I run 3 less degree from optium for safety.

Dragon, I plan on running 15psi max on 91, do you run 17* across the positive pressure load map or do you start with a larger advance and work down? What is your max advance under boost?

91 octane

actually it's much more andvance on the vaccume and lower boost areas and works its way down as the boost comes up, I also run almost no split in the no boost areas and increase the split as it comes in to the peak tork and boost areas then I reduce the split to about 5' under peak boost after it comes out of peak tork...



lol.. hope you can understand all that how I worded it.. It's kinda hard to put in to words..

The map I'm running could be more agressive, but like I said before I'm happy to loose a couple ponies to keep the apex seals intact...

I'm going to pin this for future reference and please feel free to add any ing maps you have that you feel are safe or post any documentation you may have on ignition in general on a rotary engine.
