Were you tap dancing on the pedal?
yes.. I was. thats why its flapping..
smooth throttle nothing works.. only stabbing the pedal brings it to life..
N75 has been wired direct to ecu also to test, same fault continues.
when the car first came in it has 17705 fault code which I thought was the usual issue, but no codes have ever come up since, no matter what software I have flashed in, on different box, same box, etc.... the fault is constant.
If on real road test, or longer running up and down the box simulating road drive, sometimes, randomly the n75 will come to life. Its coming to life remains until next ign cycle, and its dead again.
Only if I stab the acc pedal on off tap dancing stylee does it start up working again, pretty much on demand.
I've never ever seen anything behave like this..
If ecu's unhappy, and limp mode type event, no faults logging seems just weird.
Its behaving like the 17705 faultcode would do, but without throwing out that code.(or any for that matter)
