JWT can add the correct base idle program for any year car into any year ECU in that model so it does not matter what you start with.SERMitchell said:
For SE-R Classics...
Yes and no. The 94 SE-R did not have the AIV tube (air induction valve) If your car had it 91-93 and you get the 94 ecu your emissions will be higher and you will run a little rich. Because you wont have that program to operate your AIV. Also be sure if you don't live in California DO NOT to get an ecu from a California car. I guess they have extra emmision code crap. I just spoke to Ben today at JWT, he told me all of this.
The only thing I can think off is the baase idle mixture control. They can fix that in any year ecu though.Eric said:Mike,
Clark swapped me a 91-92 SE-R ecu for my 94 SE-R ecu because of something with that year was different. I really can't remember what it was but none the less they did. Ben told me that a 94 SE-R ecu would work when I first called but that was incorrect. I believe this only applied to my car since it is an a/t. Any ideas?
