Convert your Digifant-2 to Digi-1 ecu

by PSI (AKA chuck B)

•  
• The first thing we need to do is pull the plastic cover off the the back of the plug that goes on the ECU and slide it as far away as possible.Then we need to pry the the two peice plug apart with a screw driver or knife.With a very small screwdriver you will then be able to swap some wires around on the plug.
• Pin # 21 needs to be moved to #5 on the plug The wire that is in pin #5 gets soldered to pin #7 wire.Pin #17 gets moved to pin #15(full throttle switch).You need a jumper wire from #14 to #23.Pin#21 gets swapped to pin#20 on the plug.
• Now you need two 3 wire plugs(one for throttle switch and one for the air temp sensor).You will also need some 3 wire throttle switches.
• Now we need to chop off the airflow meter and throttle switches plugs.pull the #17 bl/bk wire and tape those to the existing throttle switch wires.This is pin#1 on the 3 wire plug for the new throttle switch plug.The br/w wire(pin 6 on ECU)is pin#2 on the new throttle switch.The r/bl wire(pin#11 on ECU)is pin#3 on the new throttle switch.
• The bl/w wire from the old airflow meter plug(#9 on ECU) is now the new pin #2 on the air temp sensor plugThe bl/r wire(old airflow meter wire)needs to be soldered to pin #1 on the new air temp sensor(the wire that was moved from pin #21 to #5).The br/w wire from the old airflow meter(#6 at ECU)is pin #3 on the new air temp plug.
• Now we need to bridge pin #6 and pin#1 on the ignition control unit(you don't need this unit for the G60).
• It sounds very complicated,its not.
