the ECU for the 1988 Turbo II should be N???
and the AFM number is N??? is it N326 or something cause thats what I have
I was wondering if my problem is from the AFM not being the correct number to match the car

also when the car starts the only way to keep it on is to stick a screwdriver into the afm to allow air to flow through... if I were to leave it on its own it starts goes to 3k rpm then dies.

I'm now 3 weeks in on the problem.
I just changed the fuel filter and had the injectors rebuilt by RC
changed the intake tubing since it had a crack on it before
changed AFM's 3 times all having the same N326 code on it.
I was thinking its the ECU since I know that the engine itself is not the US ver.
It's a JDM 13BT with lots of missing hoses and the like.
The previous owner just sealed up the hoses with screws and bolts but that sounds shady. The car does sputter when it stalls out though so idk whats wrong

If anyone is in the SoCal area and would like to look or help out please it'll be appreciated.

the car is located in Downey

 

N333

i believe the AFM was the same as the one installed in the 87 which is N332.

N326 is for a non turbo car, 86-87.

 

the AFM will be N318 for an S4 T2.

N326 is S4 NA.

the WOT fuel scales are VERY different between the two.

karacks number is for the ECU, not the engine bay electronics.

 

i was trying to remember the #'s of the bay but was answering his main question. N318 does sound correct, N326 obviously isn't. i do wish they wouldn't have changed the numbers up and matched them all like they did in later years.

 

^^ well i thank you both for trying to help haha
N326 was from an n/a rx7 for sure but it came with the car when I got it so... I'm still confused
could that be why its not allowing air to flow into the engine? because it's a totally different unit?

 

No, you can start the engine and have it idle decently with an N326 AFM on a turbo engine. I've tried it out for the heck of it before.

 

yea, it will run fine out of boost but it will be pig rich under boost and max out the n/a AFM rather quickly.
