Hi everyone. I am learning how to use HPTuners with this new of an ECM.
So, I have done quite a bit of tuning on 99-04/05 GM trucks and it's far simpler to do. I am using this truck to learn how to tune these newer Gen IV ECMs. The vehicle in question is a 2012 GMC Sierra 2500HD with the L96 6.0 and 6L90e. This is a Flex Fuel truck. It runs on e85 often. This is all a bit new to me.
Mods include:
- S&B Intake
- Speed Engineering 1 7/8 headers and full 3 inch exhaust (no rear o2 sensors)
Mods that are coming soon:
- BTR Stage 4 Truck Camshaft with double roller timing set and upgrading valve springs and pushrods.
- 3800 Circle D Torque Converter
- Champion 4 core aluminum radiator
- TruCool 40k Trans cooler and stainless braided lines
- 180* Tstat.
So right now, I am wanting to tune it for the current mods. I want it to have no speed limiter, no torque management, and i want it's timing to be increased and shift points and pressures increased once the tow haul button is applied. Anyone have any advice for me? I want the butt dyno to be able to notice a difference. Thank you to anyone with any pointers and advice!
