Took the car out again tonight and it was playing up again, just like it was doing when I first got it back.
I Drove it ten miles then switched it off for 45 minutes.
Then when it came to restarting it the engine fired up for 15 seconds then cut out. I started it again and again it ran for 5 seconds then cut out. It continued to do this for 6 or 7 times. It drove about 30 yards down the road then cut out again. I pushed it back to where I started and opened the bonnet for a minute then the engine started normally but as soon as I put the lights on it died. The next restart it kept running and stayed running with a brief stutter about 100 yards up the road. It ran fine after that all the way home.
Each time it cut out while driving the rev counter could be seen dropping to 0 when the engine was running in gear still.
I checked the battery and it had 12.75V with the engine off and 14.25V with the engine running. If there was a lack of power from the battery it wouldn't be able to start the engine so many times.
Any ideas anybody? All I can say is the car never misbehaved like this before the conversion and I'm very glad I've bought another car.

An earth? The map? A sensor?

something like that must be a dodgy earth/termination, even a 'clipped or pinched cable. cant think of anything else at all.

It must be heat related because each time it's just after the car has sat for a bit after being run for a while.
It normally just gets driven and then parked either all day long or is put back in the garage for a few days. It's when it's done a hot run then is restarted after a short while that it won't start.

its gotta be electrical. even if its heat related. could be split/corroded sheathing?
might be an idea to find a good auto electrician that can cable test, as i doubt its anything you will be able to see.
EDIT: reason i say this is the engine runs but you lose electrics (with no power to the ECU it surely must cut out)

hmm actually if the rev counter drops to 0 whilst running it could be an issue with a cam or crank sensor also?They also govern spark and fuelling dont they?

You of all people should know it doesn't use those!

Something along those lines yes...

It's a shame aftermarket cams don't run with timing marks for a camshaft sensor because then if the crank sensor fails it could have a chance of running with just the cam sensor.
I think the crank sensor is the favourite here. That could explain why the tacho drops to zero when it's still running. Who knows, the whole ECU might be losing power.
Only thing is I think the only reason the standard crank sensor is being used is to run the rev counter. So both rev counter and Omex ECU are losing the signal. Has the wiring been cocked up when splicing in the Omex?
Why would the engine sometimes cut when I put the lights on?

I thought the GTi did have EGR and the preplexed did have an ICV?

The EGR is plumbed in but with throttle bodies the exit from the head is blanked off. So it doesn't breathe in exhaust gasses. Throttle bodies don't use an Idle control valve.

Ahh didnt realise you had aftermarket pulleys on the cams. Id definately suspect the crank sensor in this case.

Ah I see what you mean now... *facepalm*
Apparently the EGR valve acts like a 5th branch from an exhaust mani when unplugged and not blanked off properly?

The pulleys are nothing to do with it. The trigger is part of the cam. These are 180 cams below, the X on the end of the cam is the trigger for the sensor.
I wish the Piper cams did have a cam sensor because I like the idea of a thorough set up like standard cars have.
