you can go less than that without a problem, I've seen cranking as low as 4deg.

Hi,
Mine doesn't like more than 5...
Cheers,
Gavin :)

I'll drop it to five, but it may be a few weeks before I can report. I may well be back ;D

Maybe I'm behind the times now 1.1.50 is floating around, but I noticed TPSdot is not reading correctly in MT. Is this because TPSdot has changed it's meaning (or scaling) now or just something bad in the v3.ini file?

Thanks.

Managed to the engine back up and running today.

I knocked the crank advance back to 5 degrees. It now takes longer to fire and still kicks back every now and then. I cannot be removing any more advance as starting will get more difficult.

Trigger before TDC has been set correctly with the timing light ;)

What is causing the kickback?

I had similar problems with 24-1 wheel. Rearrange tooth table from 0-12 (0-12-24-36) to 12-0 (24-36-0-12) and changing spark output table accordingly seems helps.

While i have an idea what you are talking about, i dont quite follow it :-\

I'd love to help but I'm stuck too - do you think its possible to re-phrase your question as that might provoke some discussion.

Ok Rob :)

During the cranking phase, the engine sometimes stalls the starter motor as if the spark has occurred far too early. Some times does it the once before the engine starts, other times maybe twice, and sometimes it just does this and the engine does not start.

It is almost like a backfire.

I never had this problem with 1.0.73 or 1.0.78, only with 1.1.44.

I also found I had lost 10 degrees on the 'trigger before tdc' value, even though nothing had physicaly changed on the engine. Perhaps this may have something to do with it.

The trigger set up is 36-1, 'trigger before TDC' is set to 54, tooth refference table set as 18-0-18-0 from top to bottom.

Infact I have just looked at a log that this problem happened on twice in a row before starting. The log clearly shows the rpm jump to almost 2800rpm and the spark jump from 10 to 33. The rpm and spark peaks are the exact same shape.

I just tuned a 60-2 setup and the rpm did shoot up and the crank to start was delayed.

one time it started so smoothly and fast it was quite strange.
Overall it always starts though

Sorry, what exactly is not understandable?
Idea is: first time when spark occurs is delayed by half of cycle than in usual method.

Im not sure where the 0-12-24-36 relate to a four cylinder 36-1 trigger when i originaly have 0-18-0-18

F**k it, im going back to 1.0.73 and putting up with the Acceleration enrichments :-\
