Doubt it's the ECU assuming you have used this as well as the engine from another car?
It's more likely to be the chip.

I have put a known standard chip in the ecu tonight. Is there a way to 'zero' the mixture screw?? I have heard that you turn it 4 complete turns in one direction and the two full turns in the opposite direction. Does anyone know if this is correct??
