Just an update,
It seems like 10 steps forward 1 step back, Whilst running the car, it started to get harder and harder to start the car. now with an aftermarket ECU you're never quite sure if it's that or something else, but it does give you access to see what is happening, one of the features is "trigger log" which captures every tooth of the flywheel, cam syn and ignition events, very clever stuff. with this feature I noticed that the cam sync sensor was not functioning correctly, a $15 VW Audi sensor off ebay arrived but I could not fit it because I was off to the UK on holiday, when I got back (a week ago) I started back on the car, changing the ignition setting from sequential to wasted spark meant I got the engine running, removed the original hall sensor from old bracket, remove new sensor from VW/Audi bracket and transplant onto original bracket, fitted this to the car , checked the "triggerlog file" and saw a nice cam sync signal, but noticed that my speed sensor started missing teeth on the flywheel as revs increased then disapearing completely above 2000rpm, I have ordered a BMW Bosch sensor, the same but with a slightly longer lead, but a lot cheaper.
I have just set the cam timing as per factory specs, a job I had been putting off for a while, as it turns out, it was pretty close to begin with
Just waiting for the sensor to arrive from the UK and resisting the temptation to respray the bonnet, front panel, repair/paint front wings, fit new suspension,,,,,,,,,it never ends
