marcinczyk Posted August 14, 2004 Share Posted August 14, 2004 picked up a ECU from the junkyard.... part number 22611aa383 F when I took my old one out it had the same number but without the "F" on it. Anyone know the difference between the two? When I installed the new one...the car started right up..but I am a bit concerned that it is not the same and I might experience something new down the road as a result. Any help would be greatly appreciated. Marty Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted August 15, 2004 Share Posted August 15, 2004 The F isn't part of the part number, so you have the same computer. Quote Link to comment Share on other sites More sharing options...
ststephen Posted August 20, 2004 Share Posted August 20, 2004 I have found that sometimes a different letter of that sort is due to either a different factory of manufacture or a "revision" letter for the part. I just saw that with a fuel pump for my wife's car, I replaced a XXXXXXXac with a XXXXXXXaf. The "af" was the newest revision of that part, as the aa-ae were crap. I wouldn't worry...
