Andy,

Sorry, I can barely help myself :-)

I've done Megajolt on a LandRover but only on a humble 2.25. I'm 99% sure that it has been done on a V8 though.

Try:

Good luck though! It's well worth doing.

TTFN.

Robert.

I saw this on another board

does this help? rough guide to ignition maps:

"As a starting point older two valve motors (1960 to 1990) should have max advance of 36, newer two valve motors 30. Then subtract 3 degrees for bores less than 89mm. Subtract 2 degrees for regular fuel, 1 degree for mid-grade and 0 for premium. This gives you a maxiumum advance number. If you have a good squish and quench subtract another 2 degrees. This should fill the ignition table from 3000 to redline at full NA load, 100KPA. For idle to 3000 rpm the advance should proceed linearly from 8 dgrees for a stock engine, 16 degrees for a "hot" engine. Below 100KPA add 0.3 degrees per 1 KPA drop. For boosted engines you subtract 0.3 degree for every 1 KPA above 100."
This is a good baseline tune, you of course have to tweak these numbers for you particular engine, modifications and environment"
