my ecu's "memory" wire is cut as well, patrick. i would make the relay/power source to the haltech as clean as possible
TurfBurn said:I guess i"m a bit surprised that you guys cut and clip so much of the stock ECU. In the Microtech installation we let the stock ECU have as much of it's inputs as it wants. We just steal the injectors and coils and the stock ECU leaves us alone basically. Works great . Hence I'm a little confused about the need to clip the memory wire and isolate the power etc.

Captain KRM P5 said:i believe the memory wire is cut to prevent the stock ecu from learning around the haltech? that has been my best guess but since the injectors are cut from the stock ecu entirely that has been a mystery to me.
ELEmental59437 said:They are cut to avoid getting a CEL, that is the only reason I see for it. If the ECU resets every time you turn the car off, then your CEL's also reset.

Just get the power from the blue wire coming out of the ignition switch. The Haltech ECU only needs 3 amps. The best source for the ground is the engine block or cylinder head. I like it better than the battery. It will absorb electronic noise better.
