Yeh I've eliminated the wiring, but no I haven't tried another ecu.You've tried everything I would, the only other thing I could suggest is trying a different ecu maybe? Have you wired the TPS directly to the ecu yet to cut out all the loom?
It happens more times than not.Does it happen every time? Or intermittently?
The Tps trace is in the bottom segment of the picture and it's the green line at the top with that spike you see? That's the Tps dropping then going back up. As you can see the boost pressure remains constant
