I just found out that the ECU im running on my turbo is an NA wut type of problems will this present

 

You'll blow the motor the **** up and it wont run right at all.

 

How did you wind up with the wrong ECU?

 

the guy that sold it to me told me its an NA ecu im running stock boost the car runs fine except for some idle issuses how can i know for sure its an NA ecu

 

Apparently you aren't going to "blow the motor the fvck up" that easily. Remove the kick panel and check the numbers against this list to find out what ECU you have in there.

 

well i got an auto NA ecu on my 5 spd TURBO wut does the #25 represent on the ECU cause ive got an ECU with 25 and that on works the one with 24 on it makes the car sputter. Where can i get the right ECU much thanks to all for your help

 

Post on www.z31.com alot more people there are likely to have one.

 

where else can i get one

 

You can, of course, buy a remanufactured one from one of the chain stores (e.g. Adavance Auto). Just tell them what you need -- year and turbo engine (don't tell them you have the wrong ECU for the core naturally). I think they run a little over $200.

 

I have an extra ECU I pulled from a junk yard a while back. Anyone know how to tell if it was a 5 speed/auto or turbo/na?

 

Well...you could check it against that list I linked to...

 

give me the number on it and how much you want Thanx

 

ok the only numbers I see on the ECU are All -B45 GO8 and 0106
