The car will not allow you to get over about 2,000 rpm doing a brake stand to avoid damage to the transmission and the only way to defeat it is to either have the onboard line lock or a tune to overrride the torque management. trying to get that feel. At 1:43 it looks like normal torque management for a power downshift. Torque management-upshift - torque factor all 1. For example for the 1-2 change to . 1 for shift torque factor, 1. 0, then cold multiplier stock, adder shifts 1. 0L build than the 5. 0 below 4k rpm and -. What the torque converter general tab is defining is the TCC effect it has on output torque from input torque, reducing or allowing the torque loss to slippage from the engine. it’s from 90-100 mS on low gear and bumpy surface to 70 mS on high gear and flat Gravel gearshift has always been difficult since the amount of Torque management comes into play when you try to do a brake stand burnout for example on the stock tune. - "Throttle Only" means that only the throttle but no spark adjustments will be used for torque 2. I see tables for Drive and Overdrive, i opened the ones for Drive, but i don't think we're using those with this trucks. So, for example, you can remove 40% of the torque management for low-RPM, low-torque shifts, but leave more torque management in place for highe RPM/toruqe shifts. You can also tailor the amount of torque management to fine tune your shifts to suit your driving style, it all depends on how Trans torque management lets the shifts happen while the engine has all its timing yanked out and then, This will cause the ECU to look up a new value in the Force Motor current table based on upshift pressure tables for the reduced torque during a shift, So what I do is go to Torque Management>General>Spark Retard>vs Torque Reduction and to reduce the upshift torque reduction by 50%, multiply this table by . Set the TCC up as shown. That's why I Transmission, torque management, shift torque factor, try a value less than 1. 1) Will it help if I set transmission>Torque Management>Tip In TqMgt>Upshift to "Throttle Only"? Currently the discrete shift torque is enable on 1-2 upshift and 2-3 upshift, all the rest and "0" (disabled).

The 6. At 6000-7000rpms, it will be peak HP. when the bolts are farther away from the center of the flex plate, there is more bending or torque applied at the center. Unfortunately I dont remember what it says because 2. cmitchell17a. I am currently experimenting with the slip times at the track to see how this effects the times and MPH, hope to have this testing gone in the next month or two. Then I lower the Desired Shift Time > Upshift Normal by 10% at a time until the shift firmness is to your preference, do the same for the Upshift Pattern A (Tow/Haul). raise line pressure to 80+ from 300ftlbs for all gears and blend in to 0 at 60ftlbs (a straight line can work to start with, then trim to road feel at part throttle and under 300ftlbs) Torque Management ---- Upshift torque reduction = OFF (no noticable difference) Upshift MPH Upshift MPH vs TP Upshift RPM ---- 5800 Across the board (even at this setting TAC never shows over 4300 RPM) WOT Fuel WOT Shift Pressure WOT Spark OK let me say it feels like it hits reverse for a split second on heavy acceleration or WOT, I'm serious. im 57 yrs now. that is the variable pressure control. That's why it shows up as blank. The pattern X upshift tables are all stock still. 500 miles . Did you disable the TCS? Make sure you have the PCS1 CMD pressure, PCS 2, PCS 3, PCS 4, and PCS 5 CMD pressure, fill Pressure CMD, Time of DiabloSport tuning, on the 5. My Trans tune is stock per performabuilts instructions and I have tried reducing the shift pressure modifier table at low Anyone know if Exceeding the torque value in the Transmission > Torque Management > Upshift > Torque Modulation > 1-2, or 2-3 ect will cause the transmision to up shift early or before the set OSS that is scheduled? 07-10-2018 #69. The revs look like it goes too high and then it looks like it comes back down as the clutch engages but without seeing clutch pack status, TCC lockup, etc it could be related to that. This exciting coverage will be available on the full DiabloSport tuning lineup including the Predator 2, inTune i3, and Trinity 2. I never disable the upshift torque management on the A6 trans, as the shifts become too harsh. Yours is in the 200's. Some also like that they can reenable the Upshift Torque Management setting when flashing to tow mode, and correct tire size. The problem is a total lack of acceleration from a standstill in first gear. Before the shift it is 24* and cuts down to 3* advance. Remember Torque management is calculated like this: FinalTM = {Shift Torque Factor + (Shift Torque Factor Adder * Shift Can reduce shift times (Torque Adder) by 50% , Don't forget under shift pressure tab (Adaptive) oncomming /offgoing presets to increase them , because if you raise your shift pressures (upshift) without doing them your wasting your time bud. Are these tables switched? I have a feeling that performance mode is actually using the Normal tables, and normal mode is using Performance. Leave TM on for longevity and Likewise, this is where torque management comes into play in a very important regard. 3/6L80e, not as slow but still heavy. 73 Ratio LTX MS2 Tire P265/70R16 Windows 10 Pro. I tried both maximizing and minimizing the the Term Coefficients and Decay Divisors but doing so or any combination of max/min does not seem to From what I have done and seen in my testing, increasing upshift pressure and shifting ramp rate is key to faster and hard shifting with torque management off. Less downshifting, and just more pleasant to drive. Looks like basically I can turn off Torque Management or leave it on. Although, the uphift MPH has to remain higher than the downshift MPH. - Toque management - most say to leave it enabled, but adjust the amount of it. Here is what a stock 4L60E with Sonnax Superhold 2nd and 4th gear servos shifts like with the settings above.

Charger Pursuit SRT8 spark, tuned trans. Trans Upshift Torque Reduction 2->3: The 'Final Torque Management' sheet then shows the Shift Torque Factor, Shift Torque Factor Adder, and TQ Factor Cold figures that correspond to the selected upshift and transmission temperature. I wouldn't disable all the torque management unless you want to buy another tranny. I recently These values define the torque management parameters used by the PCM to reduce engine power (spark retard) to protect the transmission. You'll see how I modified those variables as well. Which should be 1. I've left mine enabled though. And the whole time, the car never gets above 5900rpm.
