Matt After problem with a petrol smell after ignition. its been noted that maybe she is overfueling after my cold feed chip. so im tryin to reset the ECU. i have taken it off the batt but how long do i need to leave it for it to clear the ecu ????
Baz maybe better taking it of a night time and leave it of all night and then re-conect the battery in the morning 😃
Mark_Dj Normally 15 mins would be fine or 30 mins to be safe. I know this worked on older models but not sure if it's the same on our cars...
