Ok guys,
I have finally finished my turboed Vw corrado but a few small problems
have come up,nothing drastic.
1.when lifting off the accelerator pedal i've got no over-run cut off
anymore,on my wideband (PLX-R-500) the gauge stays on 14.5AFR,it should go open circuit as the injectors would be shut.
Using the cossy L8 Pectal ecu i have this problem,but before i had the
Pectal i was using an L8 off a delta evo.,as soon as you lifted the gauge went off the scale,meaning that fuel cut off worked.
2.Every now and then and only on a hot engine,the revs remain at around 2000rpm,as if the choke was jammed on,give the gas pedal a few stabs
and normally it clears its self.
Obviosly, if the idle valve is disconnected i don't have this problem but i get others
3.i've managed to find a rolling road here in Rome but i'm worried that
the tuner won't be able to access the Pectal software,when mapping
a Pectal super 8 system what's needed?.
Thanks for any suggestions
Andrew.

 

Maybe you should try these guys.

Probably better placed to help you than a FORD forum.

Good luck, I hope you find what you need.

 

I'm already on there mate,my engines is fitted with the Pectal super 8 injection system that was fitted to a Ford sierra 4x4 cossy.
Anyway,i've been for a 50 km drive and noticed that at operating temp. the overrun fuel cut-off works.
I'll run in the motor then look into the other problems.
