93 Cali ECU in a 94 FD
Would there be any problems? I'm planning on buying a 93 Cali ECU and putting it in my 94 FD. I did a quick search and found that the 94 ECU is the same as the 93 Cali ECU (EGR).
When I put a Pettit ECU in my Cali car I noticed the check engine light came on...but I added some other mods so I don't know if it was the sole cause. Would the CEL come on again with the 93 Cali ECU in my 94? |
Did you check to find out what engine code you were getting?
The only difference with the cali and non-cali ECU's is checking the EGR valve - there's a circuit that checks that the EGR valve moved when it was told to move. Supposedly you can blockoff the EGR valve and put a '93 non-cali ECU in the car and have no worries. But, if you plugged a '93 ECU into a '94 car with the EGR switch, the ECU may have been upset that the EGR switch was actually plugged in and working - on federal '93s the plug is loose and not plugged in to anything. What are you trying to accomplish by swapping ECUs around? Dale |
