Need help!!! Installing Apexi Neo on SOHC KAT - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Can some of you pros please help me find a wiring diagram for installing an Apexi Neo on a 89 Coupe 5speed with a KA-Turbo???

Just got the installation complete started up the car and It seems to be dumping a crapload of fuel its coming out of the exhaust in vapor form....very dangerous....practially dripping.

So I bought an APEXI NEO but cant seem to find any diagrams on installing it for a KA SOHC?? The book in the box has all SR RB and CA stuff no KA???

Some Specs
SOHC KA 140k miles with 30k on rebuilt head
T-28 turbo
Mazda FC injectors
Full 3 inch HKS Exhaust
ARC Sidemount intercooler
RFLB blowoff

Thanks any help would be great???

Here is a wiring pinout:

For afm settings, use the same as the CA18.

Pull 33% fuel across the board minimum for idle.

You are tunning on a wideband correct?

I will do my best cause now I am stuck with no car....Thanks!

You will really be stuck with no car if your af/r's are drastically off. Then you will have a car with a blown motor.

I suggest getting it tuned at a shop.
