why would you run a LS ecu? it will run on the stock ecu. should probably get it chipped and tuned though. easiest way to find out is just plug it in and try it. as long as everything is set to spec your not going to hurt anything and you will find out if it will work or not within a couple minutes.
yeah you really only need to change it if your running a different wiring harness or maybe you changed fuel injection (multi-point to programmed) other than that it just seems like you just need to tune it maybe even chip it.
yeah idk i asked him "why an ls ecu?" too he said cuz the fuel maps are different and cuz my motor is bored over its a bigger motor and it needs more fuel... i dont kno lol... ppl have told me that the motor will run but like s**t, because i have a bigger motor and my stock ones not set up for that.. idk thats why im askin lol
it'll run rich without being chipped or tuned, havent you just tried it?
run ur stock ecu and get it tuned and all will be golden
