The Official Superchips Forum

Ron,

I understand you cannot give away too many details of Superchips "special blend" but can you explain what the Cortex torque management actually changes? If it's not actual line pressure, then what is it adjusting? Timing advance/retard on the engine side? I need to understand if "superchips value 100%" or 125% may be risking the life of my 6L80E transmission.

I saw your quote from my post on the GM tech bulletin for factory flash of the transmission TCM. Knock on wood that resolved shifting issues before I ever bought a Cortex 2950. Since the Cortex, I have not had problems. I know the adaptive nature of the advanced 6L80E transmission can have hundreds of adjustments.

Thanks,
Tom

The tables we use to adjust the values for the ‘shift torque’ option are based on gear selection, throttle position, and load. The TCM uses these tables to determine how much torque to request from the ECM during a shift. The ECM will then limit power output to match what is requested. The OEM tunes these values for smooth, comfortable shifts, since that is what the majority of the consumers will want. By changing these values with our option, the customer can change how much torque is requested and therefore get more (or less) power during the shift resulting in a firmer (or softer) shift. The percentages are based off of our tuned values which we already felt were an improvement over stock for performance.



The option uses this formula: Torq_Value = Stk_Data + (Opt_Percent * (Tuned_Data - Stk_Data))



As an example, let’s say for a 1 to 2 shift the stock tuning would request 50 Ft*lbs and Superchips tuning requests 100 ft*lbs. If the user selected 50%, then the tuning would now request 75 ft*lbs.



As for risking the life of the trans, we can’t really say. However, there are customers that have been running this tuning since 2008 and we have never seen a transmission failure. We do not recommend using the max setting and this is why there is a disclaimer stating that it voids our warranty

Ron,
Thanks to you and your technicians for that explanation of the Cortex torque management. The term could mean different things to different technicians. Now I understand that Superchips is tuning "torque management" tables on the transmission controller side. So you're tweaking the transmission controller as it requests torque from the engine. Leaving the engine controller to match those requests through engine side values such as spark timing advance/retard and so on.
Thanks for clarity how Superchips does this....other tuners use other methods sometimes only on the engine controller side?

Based on your thorough explanation I think it's safe to explore the settings lower than "max." Before I was nervous to use "Superchips" value or 125% Superchips etc.....I was misinformed by others that using values less than "max" would void the Superchips powertrain warranty. Thanks again.
