My ECU is off to Rob for a check over following an incident on a rolling road earlier.
About 3hours in to a rolling road session, ignition is complete and getting towards the top end of the fuel table, we had just mapped 4000rpm and were halfway through 4500 when the engine stuttered and the car died. The mechanic shut the engine down immediately, we tried to restart but engine wouldn't turn, strangely we could hear a bubbling sound, taking the plugs out number 1 cylinder was full of fuel.
Looks as though a circuit blew on the ECU keeping the injector open, so we span the engine with the plugs out to clear the fuel and changed to another injector circuit and went to re-start. At this point the smoke decided to escape from coil number 2, something is definitely wrong with the ECU as its putting out a constant 12volts to just one coil. Having no spare smoke available we called it a day and I took a low loader home.
As I'm running large injectors on a low PW will this have put additional load on the circuit causing it to blow? The injectors are 440CC High Impedance (~12/16 OHMs) on a 2.0 Duratec, at 1000rpm the PW is 2.7Ms.
