Hi just a few questions really I've put a 2.0 S.Top zetec with fiesta xr2i inlet on. in my mk 4 escort cab efi. Ive got a DEWY ecu from mondeo and wiring loom. Any help with how to wire it in would be good. What's the difference in MAF sensors on 1.8 and 2.0 is it just the size of the housing or are the sensors different. Should I link wires into my fuse box or make a separate one. Struggling to find mk1 mondeo bits now. This is only a temp thing till my turbo'd zetec is built. Due to cvh spitting it's dummy out last week prematurely. Any advise would be great thank you.

 

Pats is no big deal to use. Focus sensors are easy to find and you get obd2 diagnostics so you see if somthing is playing up.

Zetec turbo with the focus ecu isn’t hard either
