Anybody else have this issue? While driving the lm2 reads 14.5-15 Afr which seems correct. But I open the recorded data in logworks it shows it running much richer like 8-10 Afr. I am running e85 if that is important for any reason.

e85 normal reading is 8-10, do you have you settings setup for e85 or normal gas readings?

Yeah I have it set up for e85. The issue is that the readouts aren't correlating.

Well I should ask this as well. Only the logworks has to be set up for e85 right? If not, how do you do that for the handheld device.

Hook the handheld to the computer and run " lm programmer"

Still need to supply 12v to handheld. Usb won't power it.

I just updated firmware and reset the calibration. Didnt know that was even there. Thanks, ill report back tomorrow and hopefully this is exactly what I was missing.

Just curios but what are you running this E-85 on, what mods? and how's it performing?

Just tested it...the lm2 is reading much richer, that's probably was it...thanks...as for my truck its 99 rt cc took it to the track for the first time this year and im still getting used to the act and innovative lm2...best run I had today was a 13.3 at 104 and I can't launch it over 2k due to traction issues, but it feels really flat up high...as of mods Its a 408 with the 408x cam 1.6rr mopar intake eddy performer heads polished and with a 3 angle valve job. That's the most important of the mods...it is lowered and I have traction bars.

Not really familiar with that cam's specs and what is "flat up top"?

Pretty much. 550 lift on stock rockers...when I refer to flat I mean that its lacking power on the higher rpms.

Well that will come along with tuning. I've just been real curious on E-85. Always wondering is it worth the switch?

I think it is, its high octane fuel for 3.39 a gallon here, just got to use more of it. More flexibility for timing and gives me some wiggle room for the high compression. And it makes my exhaust smell cool :p

So overall is the switch cheaper horsepower than meth inj. ? (blown app.)

I know a lot of the import turbo guys run e85 so im sure it would work great for blower....really only thing that needs to be done is add fuel to the fuel map.

ignore my post in your other thread....let's keep all the 'how'd you do it" to one thread.


so...how'd you do it?

are you running bigger injectors over stock, or bigger than the gas injectors on your 408? I'm interested in trying E85 on my 360, but I have stock injectors. not sure they can deliver enough fuel.

Actually ford racing 30lb injectors with stock tune is very drivable for me. I made a return fuel system but that really wont effect its driveability much.

i think most people wanna know what else you changed or what else needs to change. everyone hears how e85 will eat away at you fuel system if its not made to run e85. all you did is upgrade injectors and thats was it? besides you return line.

Yeah that's all I changed. The only issue may be with e85 is the injector o rings. But if that happens it will be after a very long time and are easy and cheap to replace anyway. I did a lot of research and most vehicles after 96 have no issues because of the switch to plastic tanks, plastic lines, and what not. I know our lines are plastic from the factory but ethanol is a great cleaner and will actually clean the fuel system. A buddy of mine has been doing it for awhile now on his early eagle talons with no issues.

Man I wanna try this. Everything I see about e85 on n/a motors equals out to at least 10-15 more rwhp over gas

Im not worried about corrosion. I think it's all hogwash anyway. Some guys have put aluminum fittings in a glass jar of ethanol, set it up on a shelf and came back a year later, and saw no signs of corrosion. Mostly, I'm interested in what injectors were used, and how the tune was changed

they say 30% more fuel but is that just at wot or everything? also how do you read the lambda as opposed to a/f?

Filthy Filbert
08-03-2011, 12:15 PM
exactly. those are the questions I wanna know!

it would make sense that it's 30% more fuel everywhere. but then again, with the cooling effect that the alcohol has, maybe that's enough to prevent detonation or the excessive heat caused from running lean?


I'm pretty sure though, that it's more fuel EVERYWHERE, not just WOT. because when you look at the guys who modify their carbs to run E85, they have to do some extensive mods to the idle circuit to increase the idle fuel, which says that you can't just "jet up" the WOT and be done with it.

When I was first figuring out what injectors I needed I bought the 42lbers from ford and by my calculations that was nearly a third more, trunk out it was way to rich. I could have tuned them down but im still pretty new to act so I just bought a set of 30lb injectors....works perfectly, the factory o2 sensors don't know what fuel you are running, they just read air content. So actually the computer may think its running at 14.7 but its really not its more like 9.8, the computer is just on a gas scale compared to ethanol. As far as lambda goes I haven't really touched it much but everyone that's been using it says its the way to go and from what I understand it makes it much easier to figure out how much fuel you have to change without doing much calculations.
