Jeff,
looks the same as a distributor curve, you can do far more with that if you wanted to

Start by increasing the advance at the cruise KPa from 1500-3000RPM,

Phil, I want too...

How many deg advance would be advised or trial and error keeping an eye on the AFR gauge?

Advance it a few degrees at a time, Id be looking at running 25-35deg, lean out the fuel as far as you can too. Its depends on how your engine reacts, but most will go to 15.5AFR easily enough, especially on a wasted spark setup. This may not be possible on a dizzy based setup as the spark may not be powerful enough.

Right I've been a-fiddling... and the results are very good. The Accel Enrichment will need re- doing later.

It still needs more work.
Any more thought's?

Loaded the map in that Phil posted, which has raised my 24degree max advance at WOT to 31. Christ sake, you can really feel the difference. My car is a westfield so it achieves 0-60 in around 3.5seconds but where you can really tell the difference is how quick it gets to the rev limiter at 6000rpm! Seems a lot more willing to get there. Spent a good few hours today autotuning the VE map.

It does make it a bit more frisky doesn't it. Are you using the auto tune in TS or Megatune?

24 was a long way out, 30 is more like where it needs to be, glad you can tell the difference,

Autotune in the latest Tunerstudio version.

Much appreciated Phil. VE quite close now, just a few more tuning runs.
