1. If the R56 runs on Lambda then I am just replacing one fuel with another.
2. WOT IDC will drop if I add fuel not supplied by them. It has to drop to maintain Lambda. This is why I turned the gain up to get back to full Meth FAV duty cycle.
3. I assume that the supplied jets were based on the math on the Aquamist web site.
4. 100% Meth requires the largest jet, 50/50 smaller jet. From the web site.

Why are you sure I am running too much meth?

Jan said 100% Meth for power. So 100% Meth. Now we need to know what is the sweet spot. Jan help

Didn't know you are running 100%...

And I see your theory, but it has yet to be seen how much the car can compensate to achieve its target lambda. I have only datalogged 75/25, on a .6mm jet. If you have any way to log AFR's I'd be very interested to see what they are with your set-up. You also don't know how much timing it can adjust by itself.

I've said it before, and I'll say it again....you will not see me run 100%. My whole reason for getting meth injection was to help keep cylinder temps in check. I am trying to avoid another busted piston. Meth does wonders to increase octane and dramatically cool inlet temps, but because it vaporizes so quickly at a relatively low temp, not much of it is left to cool the combustion chamber by the time it reaches it. Granted, when it does ignite, it burns cooler than gasoline...but water is the key player here in getting cylinder temps down. In the words of another Thumper: Just me............... (forgive the quote haha)

The only way to know if its "too much meth" is to a) look at your AFR's b) get it on a dyno and see if its loosing power or c) you might be able to feel it bog down.
