Abarth punto evo throttle pedal wont self learn

[Scuderia Turin]

As title really.

Car is a Abarth punto evo which has had a bigger throttle body fitted and the ecu has been mapped to suit the modifications including the throttle body fitted but now the throttle is not responding to pedal input.

I have fitted a new throttle and a known good second hand one as well as a new pedal but again when the car is running you press the pedal and nothing happens.

when trying to throttle position learning it fails to execute, request out of range error.

I have tried 3 different throttle bodies and two pedals all know good items, we even changed the engine wiring loom to be on the safe side and still nothing.

Can anyone help?

Hi,
I think that the problem is in modified engine ECU.
My suggestion, when you like to do those things, then buy yourself a second used engine ECU, clone it and then modified it.
Original stuff you can leave in some box on the side. When you have problem, you can always put it back to normal state (original)...
