Hp tuners commanded torque. Thanks for the insight!! 2019 Procharged 5.

Hp tuners commanded torque. Oct 28, 2016 · Worth noting I got idle demanded torque in gear table and a new airflow factor table by ECT and RPM added in the last 3. Now you also know max travel for tune. 5 or 12. The shift times are longer so the clutches will generate more heat if more torque is applied. I've commanded as high as 30* to get about 21*. 0 instead of the . This is where it can benefit getting it down around 20 to 40 at idle delivered. 3 Oct 5, 2008 · The following tables seem to use engine torque % on the column axis: Power Enrich Lambda; Desired Air Load; Max Air Load Torque – This table uses engine torque % in the row axis, not the column axis. When I reach my tunes lockup speed I notice one of the channels shows "TCC applied: Yes", but I do not physically feel it locking. CMD Torque Delta-Commanded Torque? HP Tuners LLC; Top; I am trying to tune a 2016 Silverado with small cam and Long Tubes, and am following the tuning school method for virtual torque. When the lock-up is commanded OFF in a two path converter, converter charge is the pressure and flow keeping the clutch off against the apply pressure. So far, I can't seem to find an absolute or definitive answer to this. I use the wideband to make sure the commanded AFR equals actual AFR, and only use "Engine Delivered Torque" to for example see if I make more horsepower at 12. When the Torque Source indicates "Pedal" sometimes the Commanded EQ follows the Power Enrichment tables and some times it doesn't and just sits at 1. Once that table is adjusted accordingly getting the Peak Torque and other torque related tables dialed in is then possible. However, if the different between the desired torque and the commanded torque exceeds the fast torque exit threshold, the torque will be ramped out "fast" to prevent too much positive throttle hence the name. anything under 700 rpm and it wants to shake bad and die out. I see where the immediate and predicted torque request aren't changing on the throttle pull, but this kind of unknown torque reduction happens on GEN V's all the time and there's no explanation for it unfortunately. jpg T eng- torque of engine T ogc - torque of off going clutch T occ - torque of oncoming clutch The 4L60E is dumb, really dumb, it is given a command to shift, and a current charge to determine how much fluid pressure to shift with. Regarding what torque converters were used in each rebuild, I suspect the first, more expensive rebuild used a better torque converter and the second failure wasn't a torque converter failure but part of a piston in one of the clutches. So sounds like lowering the torque adder table in the low torque region a few percent and bumping up the inertia factor a number or maybe two would do what I'm looking for without being dangerous. After logging the results of Driver Demand at 600kw and Peak Torque Table at 550 (nearly stock) it is clear that the Peak Torque table directly drives Predicted Engine Torque Command value and that if you simply max out the Peak Torque table you will never go into PE unless you zero the PE Torque criteria. 0 program I can make the torque converter lock up using a tech 2 or HP Tuners. Looked at this yesterday but don't have HP Tuners on my current PC, but what happens to the Engine Torque/Delivered Engine Torque and the Commanded Throttle Torque (I think it was called) when the MAF is disabled? Looks like the throttle closes when Engine Torque goes above the Commanded Throttle Torque. I scanned all 3. Jan 21, 2022 · The normalised torque sets the scale of what represents 100% load. If you increase the Virtual Torque which increases Max Engine Torque, then you have to increase your Peak Engine Torque to be higher than Max Engine Torque. Jun 17, 2020 · But also, make sure you don't raise your peak torque table in the idle areas too much, especially if you drop the VT table in the idle area. This is a significant change from older GM controllers in how the ECM: This leads to a more integrated and streamlined control process, however, it also means a change in thinking for many tuners. Jul 16, 2009 · When that was done, I have been using "Engine Delivered Torque" to determine what WOT AFR the engine makes the most HP with. This in turn increases torque, and when you increase torque at high RPMs such as 7250, HP goes up by ~1. 05-19-2018 #29 lt1z350 Nov 27, 2011 · The big thing with the torque management is that everything uses torque management, the idle spark being the most annoying. If I add another 4 I'm still at 20*. I'm not knocking and I'm not showing torque limiting active in the logger. "Maximum Engine Torque: The maximum possible engine torque, this should be higher than Predicted Engine Torque Cmd otherwise it is limiting. If I have 22* peak commanded I get around 18*. Quick Navigation GM V8 Tuning - Engine, Gas (Gen 4) Top. So far I have run into quite a few roadblocks but lately, I am making some pretty nice progress. You need to monitor Peak Eng Torq, Max Eng Torque, Immediate Eng Torque, Eng Torque, Driver Demand Torque Requested, Immediate Axle torque commanded and Actual axle torque. 0 v6 with hp tuners for a little while now and wanted to have some fun with this motor before i do the 3v swap in the spring? was trying to get some big pops and bangs but i cannot get timing to go bellow -10, tried zeroing out the whole spark torque ratio table to get rid of spark torque management but had no changes? Please help. 2020 Mustang GT 10r80 FBO+E85: Odd Commanded WOT Lamda + Torque Mgmt on Shifts Full headers with cats, exhaust, Steeda closed air box, ported intake and TB. 85 value set in the Power Enrichment tables. On the 2006-2008 TrailBlazer SS there is a TCC Apply Delay Table that we need to be able to manipulate to lock the Torque Converter when desired. to index your shift pressure tables, and index your torque management limits. what would raising commanded torque do? engine->fuel control-> commanded torque at the bottom left. I have hacked all of the open loop tables, even those that I wouldn't normally mess with. hpt May 26, 2015 · On Hold Time (Single Value): I think this is a typo in HP Tuners, and should actually say Off Hold Time, but this is a delay for the ECU to hold the AC torque value after the ac compressor clutch has been commanded to disengage before it will fall to 0. Max Torque; Max Engine Torque vs. Jul 9, 2015 · It seems like most all 2015 and newer trucks have this issue of Max engine torque being lower then commanded engine torque and they pull timing to achieve the correct torque value. eg. This is the table that was causing the Trans source for Predicted Engine Torque. Aug 13, 2018 · That said, Driver Demand Requested Torque must always be higher than Immediate AXLE Torque Commanded and Actual AXLE Torque or it is a limiter. Basically what happens is you command Torque Converter Lock Up and it has a delay table that we don't have access to with HP Tuners. commanded torque. You can see that the Accelerator Position D is around 80% and commanded throttle is at 100% but then decides to drop to 40% then raise back up just curious if anyone might have run across this problem before before I am running an 0411 ecm with a 2002 Cadillac Escalade 6. I believe the shift torque and shift time have to work together to ensure longevity. " So, Predicted Torque must exceed Calculated Torque otherwise the throttle won't be 100% open. I am trying to increase the max torque in hopes to see full commanded timing, but when I do the actual torque also increases. Reaching out for help. You may actually need to lower peak torque in 1000 rpm and under. The trick is getting these all lined up properly. However, while coasting down and downshifting, the throttle blips open during the shift to ?rev match? of sorts. Stock tune does not seem boosted more than 6-7 psi !!! Not sure if it is related to me trying to request more air load (more boost) but boost goes hits 20psi then drops to 15psi when the throttle body decides to back off. Start by lowering your commanded rpm/mph on the WOT 1-2 to allow a little more buffer between commanded and rev limit. . But it will not lock on its own. However, Maximum Engine Torque must exceed Predicted Torque, which mine does not. - Depending on engine reaction to torque reduction, gear step on upshift and engine RPM, a torque reduction value has to be input to further extend transmission lifetime - Too much torque reduction would cause a "interruption feeling" Mar 7, 2022 · I have a tune on my 04 4l60e with 6. conventional upshift control. Feb 9, 2017 · There is a table that limits torque for each gear on the M7. I've been doing experimentation trying to understand how the torque model and driver demand works while in WOT. ive upped the idle rpm a bit and it still will not maintain the set rpm. Apr 1, 2008 · Tuner in Training Join Date Jun 2007 Location Coppercliff, Ontario Posts 35. Airmass; Idle Airflow (Drive) vs. 23. 75sec shift times. I don't think you understood my initial question. A value of 255 means all cylinders will remain enabled. I finally have the spark doing exactly as commanded minus knock retard adding some more on top. May 24, 2022 · I increased the amount of timing reduction for a given commanded torque reduction , so I can command very little torque management (like 9% to 12%) and get a massive reduction in timing. Aug 26, 2023 · I have been trying to tune my stock 6. Fuel Cut Torque Ratio vs. Nov 28, 2023 · Hello everyone ive been tuning my 2006 mustang 4. e85 p51 fml trans. This also helps with the other table because you command less torque reduction means the table has even less 'guessed' torque reduction, it helps both ways. 2, but it changes the section on Torque Reduction and added speedometer recalibration. 0 but no matter the change the result is the same (295-300 torque)! Does someone have a base tune to get me started. I was doing research on Torque Reduction and found that it is a good idea to enable it at stock values for 0-3000 RPM operation to ensure the transmission lives longer. Sep 29, 2020 · 1999 7. The torque converter will NOT lock up ON IT'S OWN. For most guys with stock settings you can simply lower and raise the commanded torque in the idle table to give more airflow/torque while in gear. by definition, truncation is to "cut short" so I think I agree with what you are saying, truncation is not even allowing the power to exist, where reduction is pulling back the power that already does exist. 4x. Generally it is the torque calculation that is the culprit, especially if this is a speed density tune. 0L lq4 and 4l60e. I have rebuilt this transmission after it went out running the attached tune (with me now changing shift points, shift pressures, and tc locking). Commanded Torque Table? Results 1 to 1 of 1 Thread: Commanded Torque Table? Thread Tools. RPM vs. Torque Intervention: Enables check between throttle related load and airflow related load calculations. A log with low, mid and WOT torque shifts would be ideal. start with a completely bone stock tune put it in MAF only and tune the MAF exactly perfect if you have a big cam making less torque at idle and off idle then go to your VTT and multiply the idle area by . Here is the math Airflow (g/sec) = (commanded torque (Nm) - Torque/Airflow Offset (Nm))/Torque/Airflow Factor (Nm/g/sec) Nov 18, 2021 · Hey guys, I am a very beginner coyote tuner. Oct 14, 2010 · If torque management is gone 90psi is plenty of pressure even in a stock trans to make a quick shift. 0. Especially if I can determine that the torque converter needs replacing just based on physical observations. 8, currently it is commanded IIRC 11. At a minimum have the following PID's Trans slip, TCC slip, TCC pressure, PCS-1 pressure, time of latest shift, commanded gear, trans engine torque. The PE settings are merely to command an AFR of 12. The torque is calculated based on the torque to load conversion. When I command 'TCC SOLENOID ON' in hptuners, it WILL lockup. Desired Idle RPM; Finally, I wondered if it was intentionally keeping spark low to keep the cats hotter. The commanded A/F ratio always reads 12. I see the indicated torque being where I expect based on the driver demand I set, but the load appears to be much higher than I was expecting. Thanks for the great support!! The sequence goes like this: TCC Off Torque reduction request is purely active to stress the least possible the shifting elements. Thats it, plain and simple. 7 or so, so go and try, but reduce timing also. torque is a derived calc. I believe TQ+ is when the engine is commanded to produce more torque for transmission purposes, as opposed to shift modulation where it is to produce less torque for transmission purposes. if you simply zero the torque management spark retard table, the idle suffers as the idle over/under speed uses a torque request. Apr 30, 2020 · Zero pedal engine torque, immediate engine torque commanded, and delivered engine torque all say around the same value, my scanner shows I am sampling them all at the fastest rate although it looks to me like some of them aren't actually sampling that fast, so I may be aliasing some of the data since timing and rpm are jumping around faster It seems that Driver Demand tables might influence this, as far as I can tell. Apr 7, 2020 · This was a 2018 ZL1 1LE and no matter what you did with the rev limiter tables, he was still limited from revving past around 4000 RPM in neutral. Spark Only Torque Ratio for idle control and driver demand; Spark Torque Ratio Limit for idle control and driver demand; Driver demand torque; ETC Idle Throttle Angle Expected vs. File is attached. I am having an issue pinpointing why 1st gear has a much lower commanded boost than any other gear, while they all have the same commanded torque. im new to HP tuners and tuning all together. May or may not help you but it seems to affect Max Torque in that area when you change the Peak Torque table. Jan 27, 2022 · Engine>Idle>Torque>Adaptive Idle>Idle Torque Limit>External load - log zero pedal torque into this table VVT limiter - command 25deg advance to verify how far it can go (only if you installed correct limiter to prevent over travel!). Requestor: If the Torque Ratio Request is below this value then cylinder fuel cut will be used ETC Injector Disable: During ETC Traction control strategies the PCM may disable injectors in order to control engine torque. Also, when the Torque Source indicates "VSS Limit", the Commanded EQ is 1. I honestly dont see any real way of tuning MAF/VE accurately to set up WOT without a WB, I guess that is why GM has it so damned rich stock, so that it is a near enough is good enough approach. com Ford > Engine > Torque Management. I just increase the rows by a percentage thats constant across the speed axis, thats how the GMPP tune for the hot cam LT1 does it too. If the normaliser is 1000Nm and the vehicle load is 100% then the torque to load reference will be looked up and there will be a percentage that the normaliser is multiplied by to give the torque. 8, etc. It turned out to be the Fuel>Cutoff/DFCO>Cmd Torque Delta & Command Torque Tables needed to be maxed out for neutral. I am unable to change the commanded A/F ratio. 2015 sierra 5. RPM - This table uses engine torque % in the row axis, not the column axis. During this time, the torque source is TQ+. Probably normal for low torque shifts, I just don't like it. I purposely set the driver demand torque quite low at WOT. What drives this Predicted Torque Cmd PID? Thanks. See full list on hptuners. Be careful commanding less torque modulation in character 0 and 1. Aug 4, 2023 · That's a lot of information, but as i read it a few more times i believe this is very beneficial in learning how the ZF8 transmission works. Dedicated "E85" though the tune is calibrated to the winter blend tested ~71% fuel I could source. Apr 28, 2019 · Hi, i try to tune my 2018 camaro 2. Anyone know what I am missing? Help would be greatly appreciated. im trying to get it to remain at 800-850 but it keeps going lower and stalling out. I haven't got to the tuning side of the trans yet but this explains a lot of what we need to be looking at when it comes to applying changes to the trans to get the shift preferences we want and to also keep the trans from just eating itself in a short time. A value of "0" for any bit means that cylinder will be disabled. The units of torque or torque/time don't really fit shift pressure or shift timing so HPT had to make the shift properties tab to put it all under. I've gone thru my tune several times to make sure it isn't a load limit or something dumb and I'm just not seeing it. My father has a 2020 gt that he is letting me test on to build experience and knowledge of how these cars work. Very useful to idle tuning. Remember: its not about how HARD the trans shifts, its about how QUICK it does it. I want to make my 4l60 last as long as possible and I haven't changed any TM settings. That old school nonsense about a trans that slams the tires in every gear and hits hard on shifts is just that. If torque is high, such as after adding a cam and removing a lot from the VE table or especially doing a MAF only tune, then the ecm will try to add fuel to obtain/maintain that torque. Can I ask what "premium knock advance" means? Sorry a lot of this is new to me, I kind of picked an extremely complex car to start learning how to tune on lmao. Any PID to determine engine torque/trans. 3, KOOKS 1 7/8 long tubes, full true dual 3? magnaflow with built in x pipe, L86 intake, and throttle body, with a shade tree tune and a F**king locked T93 trans "she runs good though" plugs look nice lol I cannot figure out how to make this 10r80 follow the commanded shift point to save my life! Commanded 7700 rpm only to get 7200 rpm each shift, each gear. Once you monitor these things it will give a more clear picture as to what is going on. Torque Reduction: Master enable/disable for Torque Reduction via cylinder fuel cut. I updated Part 3, didn't feel it was a big enough change to warrant being labeled V1. I am working on a 2011 Silverado and have disabled Closed loop as well as LTFT's. This table is an 8bit binary "Enable Mask". This resides in the ECM. Right click trans slip / tcc slip / pcs-1 pressure and trans engine torque and set polling to 20Hz. 3L Powerstroke Garret 38R, 238/200 Shop built injectors, Minotaur tuning 2015 6. Hence, you'll notice all the idle torque tables in there for both throttle and spark. Thanks for the insight!! 2019 Procharged 5. By default the abuse mode seems to be disabled and I am confused whether this means I have been driving with 0 transmission torque management. Gear; Max Torque vs. Feb 5, 2005 · Also in my Transmission-Torque Mngmt-Torque reduction vs Torque vs Shift table it starts at 200 for 1-2 and is set at 10 20 30 30 30 30 30 30 37 37 37 37,,,,2-3 starts at 240 and goes 10 20 25 30 30 30 35 35 35 35. Take a log and post the logs and tune, including the stock and modified tunes. Once lock-up is commanded ON the flow reverse and now your converter charge pressure is what applies the clutch. E 78 and E 39 ECMs use a torque based control structure that is similar to systems used by Ford and Dodge. 7 and smooth one row/column out so that it wont pull lots of timing at idle and buck off idle while spark and throttle fight each other. Logs are showing around 0. Show Printable Version; HP Tuners LLC; Top; All times are GMT -5. How do you ever get the max torque above the actual torque? So I am trying to back into how the PCM is calculating torque and airflow, I see how HP Tuners laid it out in the formulas, but the math is simply not working. In vcm scanner, I notice there are 3 channels for "TCC applied". Is this a Torque management setting that I am missing? I will post a log and cal file when I get a chance later tonight, work computer for now. I had a custom tune sent to me and it still doesnt want to idle. 7L Powerstroke Sep 12, 2015 · Torque reduction is torque allowed during a shift(y-axis is torque converter torque)(table populated with Out put shaft torque values). Is that right, or is there something else? I understand some of the torque balancing that has to happen, but was hoping to get a better idea on Immediate Engine Torque Command (IETC). This applied with 6r80 and still applies for 10r80. Running out of ideas. 0 update. Personally, I would start by lowering the commanded WOT shift RPM on the 1-2 to say 6000 and make a pass to get data without being on the rev limiter (hopefully). 0 that has almost all torque manangement turned off when comparing to a stock tune. It is missing for this particular OS in HP Tuners. Have you got a stock tune to compare to. mri ehft tpmnw xipo glsx yfa wzsd afpql vvk rgdon
