Reprogramming LT1 ECU

[86Cutlass383SR]

I know differant states have differing requirements but if I understand things correctly (and I may very well don't) as long as the engine is newer and all emissions for that engine are retained, it's legal. For an engine swap for example, of a 96 Camaro LT1/auto they'll probably look at engine numbers to verify the engine. Then they'll look to see all required emission parts for *that* engine combo. Car will then be tested and if visual passes and tail pipe numbers equal or less that said engine, it's considered legal. As long as you are reducing emissions, that's their concern. Emission wise, your car is no longer a GP, it's a 96 Camaro.
