Have I fried my ECU?

Just incase anyone stumbles on this in the future; I had my car delivered to thor racing yesterday. They were able to diagnose and rectify the problem within an hour..

 

Basically the 12v feed into the ECU which controls the main EFI relay (pin 31 on the single multi-plug), had a bad connection. Someone ([OOPS][/OOPS]) must have been a bit rough with the wire, and caused it a bit of a mischief. One of their engineers was able to source a replacement section of wire with a decent crimp on it; he fitted that into the multi-plug, soldered it in to loom, and the car was running fine.

 

I'd like to add that although i'm a "hav-a-go-er", somethings are best left to the professionals. I was tearing my hair out trying to figure out what had caused this problem, and they sorted it in an hour....

 

....Oh, and since visiting there today; i'm very much interested in the v8 supercharged conversion I spoke to them about :eyebrows::eyebrows:

 

Pezzler, interesting thread, glad you sorted it. I can only imagine that as the load on the 12v rail increased the voltage drop across the bad connection increased resulting in low voltage on the main rail within the ecu.
