LH6 ECM choice
LH6 ECM choice I have a 2006 LH6 out of an Envoy. I came controlled by an E40. I have a harness and E40 but I've seen some comments that the E40 can be difficult to tune. My plan for the engine is to bore .02" over and run a Truck Norris cam and possibly an LS6 intake. It's going into an 84 Monte Carlo SS.
My question is this, is there any reason that I can't use an E38 to control it? ID also like to run a 6l80 behind it but I'm not sure that I'll find a TEHCM to match the 07 E38 OS.
I appreciate any input!

E40's are for 24x crank triggers
E38's for 58x
If you want the 6L80E, swap the crank for 58x during the rebuild. Then use E38, E67 or whatever you want. 24x/6spd is very challenging
If running 4L60E/80E or non-CC trans, I'd use a holley terminator which doesn't care what crank trigger is used
Save the oddball E40's for Colorado/trailblazer guys who don't have a choice in ECU
