ECM problem
My question is I have a 98 ecm now will switching to anything 99+ give me issues? My father in law has an extra ecm but unsure what it came from (ls1 truck swap) ECM # 16220610 service number 09354896.
Edit: did find out the space ecm is from 99+ 5.7 car so I guess the below question is null.
additional question is since I have HPtuners I can just transplant my tune onto it without issue?
