CAMARO6 - View Single Post - Camaro 2016 with LT1 or TTV6 can be tuned without affecting warranty

I have to strongly disagree on this one. The 2010 and 2011 V6 with the LLT engine/ Bosch ECU is the only recent engine I know of that shows no evidence of a flash counter and has gone through several warranty issues while tuned without GM voiding the warranty.

The 2012 and up V6s with the LFX, and the L99/LS3 V8s with the Delphi ECU's have a flash counter. The LT1 V8s are similar in many ways the LFX V6 and I believe also use a Delphi unit.

So I'd be shocked if there was no counter on them.

GM has so much torque control programmed in to the LF3 TTV6 that it literally limits throttle input to 50% up to a certain rpm along with many other things to limit torque such as reducing timing. No way GM is OK with someone simple tuning that all out. Surely they are keeping an eye somehow on that kind of thing.
