So you cannot adjust that setting so the timing flashes zero ?

As Rob I think mentioned. You could perhaps do a sneaky one and turn cyl 8 into the first cylinder to fire. This may then place the missing tooth in a more usable position.

Where does the edge fall in relation to No8 TDC ?

At end of day, ecu doesnt care which cylinder is which, as long as the order is correct for the engine to run. Just some ecu settings and pin swapping, HT lead changes.

Although IMO sorting the crank trigger would be easiest.

But even at 9deg BTDC firing, the engine should start easily.

I thought further about fudging it but it won't work. If the sensor had been fitted around 110deg you could have done it.

Don't pull the engine out just yet.

Double check the transition from cranking rpm setting. If you made this very high like 4000 the engine should run on the 9deg you have, also I've checked the manual and it says the crank trigger can be 80deg btdc not 70.

I think he says the software wont allow him to enter 80.

That's correct Steve it says max 70 in the ECU , that's where I went wrong it says you can set 80 as max in the manual which I did before I fitted the motor . But have been making up new brackets for the trigger and I have been able to get it to zero at tdc and that's with The timing light but still need to put it back together to dry a start up . Jeremy

Try running windows 7 in XP compatibility mode, you have to go in as an administrator to do this I think, often needs this to run old programs like DTAWIN
