to start off, i've been going through these 2 links alot lately, only to go back and find that I followed each %100 besides actually installing the turbo. from what I have read, you can install the turbo ecu and still drive the car with the turbo ecu, as a n/a engine on 450cc injectors.

car starts and stays running, but idle sounds off. TPS and IAC/ISC fully tested impedance and checked the ISC moving when you put the key in and turn it. car runs otherwise when you rewire back for a n/t ecu. getting gas to the rail and you can hear the fuel pump, sounds like its misfiring, but not getting any DTCs from evoscan.
thing is, I have a 99 spyder body and a 95 eeprom ecu, later read that 95-96 ecus had an inverted signal in comparison to the 97-99 cas, for turbo model CAS that is. I still have the factory sohc head in place, with its CAS. not sure if the same applies for the 4g64 CAS but probably so, Ive switched around spark plug wires with no better results. Car drives like crap as if ignition timing off but non-adjustable CAS and timing is checking out fine at 7 degrees on the crank with the timing light.
have a new 97 ecu otw to see if any changes. hoping for the best. not sure what else I can possibly check. there are 3 wires on the cas plug, red, blue , black, just like that, and the 2 ends put out 12v when checked on ignition. so middle must be signal. not sure if anything can be rewired there either.
