Howdy all,
I have a 2008 Silverado that had the LY5 engine swapped to a 2011 LC9. All of the sensors on the engine were swapped (like MAP) the MAF is still the 08.
I know I need to change the MAP calibration to 11 and the injector flow rate to the flex fuel values. I am wondering if I need to reconfigure other tables that are different between the 11 and 08 years, for example, the VE coefficients for speed density, octane scalar delta. I also assume since the LY5 has a 9.9:1 compression ratio and the LC9 has a 9.6:1 compression ratio i should update the high and low octane maps to the LC9 version.
I have attached stock tune files for the two respective engines, am still very new at this and appreciate any advice for my current situation.
