I have a 1995 SE 5-spd and I was going to get JWT to work their magic on my ECU. But since it takes 3-4 weeks, I was going to get a second ECU so that I can still drive my car. My plan was to get the second ECU, swap it out with my own ECU and send my ECU to JWT to program. Now, while searching for ECUs at local junk yards, I found that the ECUs for 1995 Maximas fall into 4 categories for production dates:

upto 5/94
6/94 - 8/94 (my car falls into this one with a date of 7/94)
9/94 - 11/94
12/94 and later

When I talked to JWT, Ben told me that it would be BEST if I could get an ECU from 6/94 - 8/94 so that I don't run into any check engine light problems or anything funny like that.

But my question is, what if I get an ECU from another one of those dates... or an ECU from 7/95 (for a 1996 5-spd SE)... since I only need it for 4 weeks, would there be any harm to my car whether or not the check engine light comes on, due to compatibility issues?

What would you guys do? Would you try to get the exact match or would you be able to use another one of the above part numbers? Thanks.

EDIT: One ECU that I am consideing is A18-B41-EL0 (production date 6/94 - 8/94) and the other ECU that I am considering is A18-C84-EYO (production date 7/95). My car is a 7/94. Would the second ECU cause any problems, compared to the first? Is there any difference?

 

These guys seem to have the ECU you need http://www.logels.com/ for $175
Search for your ECU.

 

I know... that's one of the ECUs I was referring to. Plus, this wrecker happens to be down the street from where I live. But the other ECU I was referring to is WAY cheaper but not the exact same model as mine... that's why I was wondering if I could get that without any problems.

 

There is a g-force ecu in the for sale section.

 

I need a stock ECU.

 

He was suggesting that you buy that ecu and you don't have to worry about waiting for anything.

 

I've got an ECU I will sell you while you send yours off to JWT. It's from a 98, it will work just fine. I drove with it in my car for a week. Only thing is it will probably give you a check engine light. Functionally your car will be fine.

 

I went ahead and paid the slight premium and picked up the ECU that has the same starting code as my car so no CEL problems. But I guess you could help me out here... how do I swap it out with my ECU? Is there any place with detailed directions?

Thanks!
