Thanks, I will try that tonight. I have a friend with a vw and his is set to 51 degrees using the speedshop system.

That would be about right then, the crank scope is an estimate.

Alex, when checking synchronisation it switches between synchronising and not synchronised. Any idea what I may be doing wrong?

I suspect the original issue is still present, and you're getting some signal dropouts.

Are you getting any crank errors?

Have you revisited Paul's fitting instructions? he specifies a gap of 0.015 thou.

When we wired the injectors we grouped them so that 1+4 fired together and 2+3. to match the VW firing order, could this be the issue?

Tried a different pickup yesterday and it worked much better. It synced and even got to running status. However it must of been out on the timing as it kicked back and knackered my starter motor.
Next job is to properly mount the new pickup and set it all up again.
Thanks for all your help.

For a vw flat 4 the injectors should be wired 1+3 and 2+4 as the fireing order is 1432. If running batch just put them all together.
