The story so far....

Update: we installed the 760 secondary injectors. Now the car *definetly* pulls harder past 4k put it's still running lean...
I'll get that S4 TII ECU + boost sensor + FCD and be done with it (I hope), I'm getting tired of this problem....

Now, which ECU should I get? (I'm a little lost with all this 3xx numbers...). I understand the 318 is the '88 TII one. Which other ECU can I get?

Looking forward to post a "My FC runs amazing!"...
Best regards

 

Is your fuel pump wired right? Also, you want the ECU from an 88TII car. if you didnt swap ECU's when you did the swap, that's probablty the problem, But I'm no expert.

 

Ok, I slapped in a borrowes 318 ECU, 318 Boost sensor and FCD and.... exactly the same problem.... it changed just a little, little bit...

Ok guys, now me and my mec are totally blank..... does anybody have a suggestion? We are completely lost....

Heeeelp!!

 

I forget what a 318 is(Jspec ECU?)

US TII ECU"s you can use are N332(87TII) and N333 (88TII)

 

the first two numbers have to be the same in order to swap.

s4 TII's have N332 and N333 like Digi said.
