tell it the air is colder ECU will richen the A/F ratio..

Yeah just trick the MAP sensor/Air temp to be cooler etc.
But how would you do it when you are in open loop? when it no longer looks at the sensors due to high engine RPM? The RX3 Delphi at 6000 and up RPM runs on the map no longer on the sensors etc.
