So, if you use Shiv's tuning guide to make a new map, store that map as your map # 2 in your XEDE and use it ONLY with race gas.
Exactly!

Ok, great thanks. I'm not that dumb to run 91oct on a race gas map.

Now what if there was a bit of 91 left in the tank should I try to get the tank as empty as possible (without being stranded on the road) before adding 101oct for the race gas map? Sorry for the questions this is my last one

Shiv builds a little safety margin into his maps, so you should be fine just waiting for your low gas light to go on, then adding 101.

all questions in re: to stage 3
could i use the same maf adjustments to tune for race gas?
why is my crank timing all at zero after custom tune?
did you tune it through the flash?

how do you calculate how many cc of menthol will allow me to lean the AFR by 1 ??
or better yet which size of Jet (which shots menthol) should I use to make 91CA gas compareable to 100 Octane gas

Could the same general techniques be used for my car with the addition of 100 octane?

There should be a warning about using this method on methanol injection systems. Most systems on the market use a different nozzle size and have different flow rates. The Buschur racing Alcohol system has a flow rate of 7 gal/hr (442cc/min) and a standard Aquamist system uses a 0.7 nozzle which flows roughly 260cc. Even using a 1mm nozzle on the Aquamist system will only give a flow rate of ~340cc/min.

Maybe Shiv can tell us what the flow rate needs to be in order to use these mapping techniques safely.

BUMP....

I used this process to build my race gas map and I recently used both maps in a standing mile event. From a dead stop to the one mile marker on pump gas I got 143mph (checked via radar). After adding 110 turbo blue to 93 making a 100 octane mix AND changing to the race map I pulled 152mph. Nice gains to be had with race fuel.

I would like to run straight 110 leaded but I'm not sure how I would take advantage of it. I doubt adding timing to the timing table will help and my stock turbo is doing all it can do to spike to 26PSI. Advice?

Anyone bother to save these 6 images? Unfortunately, they were not saved in my copy.
