hi its not the fuel, it looks like the loom is knackered as its not picing up the map sensor hence flooding the car with fuel, loom has seen better days so on the look out for another one, its not worth repairing it.
also it doesnt matter what chip you fit or injectors or map sensor the engine still runs fine what ever, tried my ecu with stage 3 chip in my mates standard cossie and it ran fine.
acossie tuner said it was perfectly fine to try someone elses ecu as a process of eliminating that as a problem! couldnt see how a ecu could possible blow my engine up anyway, fair enough using the wrong set up and driving it, but i was only ussin the wrong set up to see if it would start
