I have a E40 ecu that we are using on a 1969 Camaro. The ECU came from a salvage yard and is suppose to be for a 2005 Envoy XL with a 5.3. Can anyone verify this # 12577191 so that I know what to buy. I also need to know if the HP tuners can work with a Accelronics box to control the 96lb injectors, and what map sensor can I use.

Thanks J
