Dzik,
Welcome to the club of those who have had the same problem. If you read my post above (and posts from others) you will find we have all had the same result.

As far as I am aware, the problem was never resolved.

What you can try is as I did, re-program the chip, and it may be ok initially but it will fail again after a very short time.

I had one chip that did not recover.

Source code was never released so no one can check to see if the problem lies there or not.

All the above is the reason why John and Nyemi decided to start the new ignition with the 12F683 chip which works fine.

Read the complete section as there were a couple of initial teething problems.

There is currently a move to change the "working ok" system to multispark and also telemetry tx but this is in a new section.
Best to read all.

Don't know if Gompy would care to comment as many of us have respect for his efforts and any help he might forward.
