Alcohol kit... Am I lucky or what???

Rich plus advanced timing = super low egts and no knocing with the alcohol.
Remember when running alcohol it has a lower ideal ratio trhan gas so when combined with gas the ideal a/f is lowered slightly.

is there anyway to put a gauge to monitor alky pressure when its active, this way you would now if its not working right

Of course, we used the XEDE to switch maps. The next step, of course, is now to develop a software update to induce a fuel cut when the AFR goes lean (which is what happens when the Methanol injection fails. This, IMHO, is the only way to actively take precaution against this very real shortcoming.Shiv

You will then need to yank out 20-30% fuel to compensate so that AFRs go to around 11:1. You can then add in several degrees of timing across the board and raise the boost several PSI. On the last car that we tuned (turbo magazine's Project EVO), we ended up gaining 60whp on our DD dyno. That's close to 80whp on a Dynojet Of course, we used the XEDE to switch maps.

Just for reference - by personal evo which runs the latest revision Buschur Racing Alcohol kit exactly as I sell it to the customers, runs a very rich 11.1 / 1 a/f just like I tune my customers Evos and I am now making 690 whp max and went 9.98 in the 1/4 mile.
From my experience leaning out the a/f by half a point to 11.5 is worth less than 10 - 15 whp with the stock turbo.

i was on my way to an autox event when my boost gauge stopped working. i just thought a line came off and thought no biggie. well i was right. the boost line came off where the alky kit controller tees off. which means the alky wasn't spraying. i ran the whole event, with co-driver (16 runs or more total) with my boost set at 25lbs. never heard any pinging. but to me the car felt slower.
am i lucky i didn't grenade the motor????
