I just found this post - very late I know. You stated at the start that you were using 20psi fuel pressure. That seams very low as most EFI engines use approx 45psi (3Bar). Not sure if you ended up sorting it all out but low fuel pressure would give you lots of dramas.

The loom was modified by The Castlemaine Rod Shop to work without the BCM and ignition key. I purchased the USB ALDL...

Your Rod is looking good Peter. I feel your pain as it took me 4 years to get my 1972 Beetle on the road and then I have spent the last 10 years modifying and changing stuff. But it keeps us a home where the missus can find us. The dash is looking neat, nice and simple and I see the changes you have...

Thanks for that info. Might help me locate a suitable loom.

Also after the ECM plugs to suit the VY computer. That engine is going i...
