Razor, How do you figure out what percentage of your burned mixture is meth vs. gas? Jay

Eric, lambda is much closer, but the target of lamda is still not equivalent for all sources. According to this source: http://www.engin.umd.umich.edu/research/undergraduate/reports/REUReport5-EmissionsE0-E85-2004.doc.pdf With gas, your target lamda should be 0.85 to 0.90 whereas your...

Razor, Last year i had a car setup running a very good tune with an AFR of 11.9 running straight 92 octane (no alchohol). When I drove home, I had to run my local gas which is 10% ethanol blended. My AFR stayed the same, but I noticed way more knock and had to pull timing. Eventually I...

Razor, you lost me here. If you spray too much meth (and I presume this means that your mixture is burning alot of meth) your AFR would drop becuase meth has a much lower stoich value. So as you spray more and more meth and then bring out less gas, shouldn't you be targeting a lower AFR? If...

Targeting an AFR of 11.3 would only be valid if you burning about 80% gas and 20% methanol. This may be the case in many instances, but not necessarlily so. What if you were burning 50% meth and 50% gas? Then your AFR at 11.3 would be so lean your motor would last a second. If Stoich for...

I am switching from a non-progressive setup that had a lower pump volume, to a progressive setup with a much bigger flow capacity. I'm also going to be using a ECU that allows the WBO2 to adjust the fuel curve to a target AFR. The problem I foresee in tuning this setup is that i have no...

Correct, Crawford R3 and running a hydra ems. Not exacly sure how it will be hooked up but I think I'll have the hydra (similar to the FAST ems) turn on the Alkycontrol PAC. The Hydra uses a GM 3 bar sensor as well so I assume that I can wire up the same sensor to the ecu and the PAC? jay

Nope, Subaru STi. But the short block is far from stock. :D

Razor, I bought two its from you last fall, one for my Syclone and this one I'm putting in a car with a 2.65L 4 Cyl (forged rods, forged crank, forged pistons, darton sleeves, and a Garret ball bearing GT35R) that makes 550 wheel hp on C16. jay

I was previously running a SMC kit that I bought around 2000. With it, I had two M10 nozzles and would run the pump speed at around 3-6 (depending on my boost level). After a pump and controller failer, it's time to upgrade and I now will be switching to a new Alkycontrol PAC setup. My...
