i need to find out about this ecu x1a that was in my 89 but when i check the calibration it's from a 91 i would like to see what other i can use for a 89 auto in california this one is a F1WF- 12A650-BA with code X1A thanks guys i try to search for it but i can't find the link to the ecu family group thanks again
 
Well, I think you found your problem at least. A 91 EEC in an 89 will cause severe sensor errors not to mention short circuit a couple of injectors....

You need C0S to be able to run without EGR. If you have EGR then any 89-90 EEC will work fine.
 
Hey Becerra, I think I still have an extra C0S I picked up from you a while back if you dont have another. ;)
