Yes I am working on the Mk1 Focus Rs management at the moment.


I've done the pin outs and I have mocked up an engine.

ONCE TESTED I post up the info for all but ive had a few bad weeks so I am a few weeks off posting them up. Ive got a mate that's used the info to Beta test it and says it goes like shit of a shovel but he is working through a few wiring niggles.

The St170 rwd on oem management I did.


ive done the silver top 2.0 Zetec ( pre and post pats), the black top 2.0 Zetec , the ST170 Duratec/Zetec and the 1.6 Zetec SE.

I've nearly done the Rs and have the 3.0 ST220 to go at next

Yeh but until live checked them I don't give them out.

Your not going to like me if your new aftermarket ecu goes up in smoke.

Do you know the dash gets its info down the bus from the ecu ?

So things like rpm, coolant temp, the dodgy boost gauge and even the speedo ?

Thats a fair point. Yeh I've looked on etis and seen that th e ecu runs the dash but I will be running a aftermarket digital dash aswell, I've worked out just over 40 pins on the ecu from etis but that's all I can see from the diagrams :-(
