Update time.
The car was up and running a few weeks before Christmas and waiting for a mapping slot at Track and Road, one of the only rolling roads I would consider using.
To cut a long story short we were being plagued with a misfire which after lots of messing about turned out to be the hall effect crank sensor Dave had been advised/requested to use instead of the tried and tested, very reliable VR sensor.
I even bought a second sensor to try, both were from efi-parts/scoff along with his triggerwheel and in the end all the problems that were caused were down to a poorly advised sensor selection. What it comes down to is that the sensor is not suitable for reliable crankshaft trigger sensing.
Initially it was thought that the ECU, wiring loom or brackets were at fault. This was completely wrong and everything else was working correctly.
Along the way the Emerald ECU we are using got blamed for the issues which I took up with them. They took the hardware in for testing and kept us updated, the only delays being the snow held up post. The customer service was excellent, they are easily contactable and they didnt charge for the bench testing even though their product was not at fault.
Emerald software is well developed and the hardware is reliable, they arent using your vehicle to develop their product. Track and Road are very good at what they do. Having so many years experience developing and mapping with either DTA, Emerald, Omex or MBE it would be foolish to use another system.
So Im fitting a new VR crank sensor and back to the rolling road for a final session. The engine sounds very smooth for a PRV and hopefully should make adequate power whilst running moderate boost due to the ceramic turbos..
Would like to put up some photos of the car but think Dave wants to keep it under wraps so he can show it off when he's back.
Cheers,
John
