I'm clawing my way out of Gen3 and getting more involved in Gen4 but it is a slow process. We have a t56 put behind a bone stock 2011 5.3 truck engine. The 4/8 cylinder cut has been disabled but I can't decide what is the best way to tell this ecm to not care about it's lack of auto transmission. I have considered trying to work with a camaro LS3 manual trans tune, but then I would have to reinvent the engine tune for this bone stock 5.3 engine...that sounds like a bad idea. The other thought was just to not worry about it, turn off all the codes that might pertain to the auto trans, and see what happens. If I do NOT have a grounded pin at X1 Pin 1 then won't the ecm just think that there's an auto behind it and that it's in gear (aka a suitable condition for a manual trans engine to stay in). This option seems too easy, surely something in the tune would wig out if it didn't have any trans data, right???
Am I over thinking this? Any help is appreciated.
