Default ECU/SUPERCHIP problems on going.

Hi everyone,

Im having trouble with my car not working with my superchip! all started when the car stopped working one day an wouldnt start, i have a friend come round and look it over and found soon as he unpluged the Superchip it started! (was fine before it failed on me boosting 20psi ect so chip was working!) the car runs without the chip (rich and cant take the car over the 7psi limet!

when the superchip is fitted it makes the fuel pump buzz and the relay's tick no stop, As soon as the chip is out its all fine!? the car wont start at all with the chip fitted.

CHANGED SO FAR-

Tryed 3 different ECUs (same happens when chip is fitted)(fine without chip)

Changed CHIP for new one under warranty with superchips

Changed ECT sensor

had the car in for a quick check over but no luck in finding the problem

has anyone had this problem before or fixed this problem!

lots of help would be great thanks

Sound like the chip is fcuked they can some time's do that it came be water damage when it get's rusty around the ECU. You can have the chip reprogramed but it's some time's cheaper to just buy a second hand one.
