i have an 88 gtu and the shop (fnr) says that it needs a new ecu and afm and i found one locally on craigslist for like 100 for both and i just want the car running. will the s4 gtu run with the 87 t2 ecu and afm?

i searched and didnt really see anything

thanks in advance

 

Nope. Use one from the same series/style, and make sure you match the numbers up.

 

what do you mean by numbers?

 

I have an s4 NA ECU and AFM if you are interested? I live in the Twin Cities.

 

The ecu has numbers. N338 for instance, is the number on my 88 convertible ecu. The AFM has numbers on it too, just look.

 

There are numbers on the ECU and AFM.

 

potentially im just trying to get the car running so i can sell it and im not sure what the numbers on my ecu and afm are..... how much and i can pick up

 

i got the ecu, afm, and map sensor for the turbo 2. still all working... it should work as i was told by some members that as long as its from the same series, it should swap in. only difference is that there is no turbo, injector sizes are different, no boost gauge; but should work.

i bought these from forum member "spooledupracing". he sold me this because i told him i was trying to turbo my NA. i was planning to port match the intake manifolds and get a stock turbo. but i sold my na before putting those in since i had too many issues with the car... timing was probably way off. idk... anywho, he told me to swap out the ecu, afm, map senosr, injectors, and whatever. or you could just plug in all the ecu and afm. i believe if you switch the map, then the fuel settings will change. you can try to swap the map sensor too.

 

the turbo ecu will not run correctly on an na, mainly the injector size is drasticly different, and so is the map sensor output.
you would need turbo ecu, no emissions solinoids pluged in, turbo afm, turbo boost sensor, and turbo injectors for it to run half way decent. on an na.

 

You need an N326 Ecu and N326 AFM..
also you need the Presuure sensor,N326.

 

A turbo ECU & AFM will make the engine run very lean, and the boost sensor difference will screw up the fuel map and the timing.

Use matching sets of electronics only. N327 & N338 ECUs will also work in place of an N326.

 

I got like 5 s4 n/a ecu's laying around. And MAYBE a s4 n/a afm. $25 each shipped. PM me
