Has anybody got a pinout diagram for a ecu A18-000-DV8 STI 3 pin,
cheers

 

That's not an STI ecu, I'm pretty sure that's for a UK turbo 2000.

On the sticker above those numbers, in much bigger type will be 2 or 3 numbers or letters. What do those say?

 

says SP in pink writing

 

In which case that sounds like a Prodrive ecu. Give me a clue as to what car it's fitted to.

 

its a 98 classic

 

This should help ya.

ty. is that not a 4 pin one tho?

 

Scroll down the page.

 

i am after ignition control and tacho, sure i have tryed that 98 diagram and was not same wiring and my car?

 

the pin outs on JGMs site are correct for your car. my97 - 98. 3 plugs. only possible difference is the cam and crank and fuel pins, but thats a difference for uk and jdm cars.
engine speed output is b135 pin14
Ignition control is b137 pin 10, and b137 pin 9, number 1&2 and 3&4 respectivly.

 

ok cheers ty all
