Wow. I'm glad I did it. F*** methanol injection lol. I don't even have the tune dialed in yet as I just filled up the tank this morning and have maybe gone 15 miles. It smells a little funny, but you get used to it. The amount of low end power gain I got combined with maxing out timing (27 degrees) on the Harrop with a 2.6 pulley EVEN on this hot ass day is like putting on a bigger Harrop lol. It's nuts! There is NO reason you all shouldn't switch, unless of course you don't have E85 in your area. I just made some PIDs for HPT and used my wideband in gasoline AFR mode. Worked pretty well and the factory EQs and the PE EQs I had set worked pretty damn well. I changed up the closed loop EQs to give a better idle and cruise, but that's the biggest thing I had to do really. I will be doing a detailed write-up on converting and tuning for those interested.

 

Where did you get E85 in Morgantown?

 

good to know. im looking to convert in about a year

 

Very good choice!

 

wow im really wanting to swap to e85 on my 2.2, woudl help having colder fuel, lowering my iat2's, and allowing me to run more timing but dammit only 1 filling station here in the city, i would be pissed i f had to calla toll truck to tow me to the other side of town if i ran outta gas

 

Dulaney Oil. They've had the **** since like the beginning of time lol.

And if you live in Mo-town, how have I never seen you? I'm sure you've seen the silver bullet zipping around.

 

would E85 help in a tc?

 

whats all needed to run e85 in a lsj, i heard just 80lbs and a tune....is that ture. im just curious?

 

im no expert on the subject but i would say wait. you need to pump in way more fuel, and as i understand it, tc guys are already at the limit of the fuel system until tuning comes around

 

I don't even know where that is. I've seen a silver redline before in motown so it prob was you. Just picked the balt up in July, used to have a silver srt-4

 

i dont think u guys could run it, e85 requires about 30% more than unleaded gas, so with a injector upgrade of some sort yes it would...

 

i dont know if you can do it in the lnf's cause of the more demand of fuel needed/ least thats what i have been hearing/, so until theres bigger injectors for the lnf, i dont think it can be done....not 100% on that thou

 

Yes, just like methanol would. Can DI handle E85? I'm sure it can, but I'd look into that first as E85 requires a stoich mixture of 9.7:1, which requires A LOT more fuel than regular gasoline. The reason it doesn't load up an engine though is that it burns faster. Granted, the lambda and EQs end up pretty similar.

 

Yup! Personally I prefer the Lucas disc style 79lb injectors. The stock pump has no problem with it though. As far as the tune, in all honesty if you have your MAF/fuel tables dialed in, all you really have to do is change the stoich value to 9.7 instead of 14.7 for the fuel calculations and it's that simple really. I changed some of the OL/CL tables for a better idle and cruise, but that's about it.

Just did.

 

ok cool thanks cause i been debating weather or not i want to do this, cause there only 2 local gas stations near me that i can get e85 from currently, thanks

Well there's only one within 30 miles of me and it's only open 7:00am to 4:30pm and closed on weekends and I still took the chance lol.

 

damn so your running E85 100% of the time? eff that.

if ur willing to spend the money it's a great alternative to methanol and race gas, but i couldnt see running it all the time.

good job for setting it up on an LSJ tho. first one i've seen have enough nuts to do it.

 

how much more power are you making?

 

.i dont want to run e85 all the time, cause i dont want to have to carry my hpt and pc with me all the time in case i cant fill up with the e85. i was looking at it for in the sense of having for like a track day only persay.

i heard of a few lsj's doing it one being local but i dont talk to the guy,

for an lsj i head like 10-17hp thats what i heard dont know if its more or less......thats just a ball park of what i heard....... but theres other plus's to it thou, cooler fuel, burns cleaner, and you'll have less knock if any.

 

i see, i must have missed any posts for them. shitty still having to run it all the time tho. that **** doesnt like to be transported in warm weather either.

when i was running it in the evo i kept the extra tanks of E85 in my extra fridge out in the garage. lmao

 

It's not a big deal. It's not my DD, but it can pull DD duty if it needs to. Like when it's nice for a week straight. Also, it's simple to switch back to gasoline. I just take off the nitrous fuel line from the test port on the fuel line, put a hose on it, jumper the fuel pump relay to turn the pump on, drain the tank, fill it with gasoline, put my gasoline tune back on, and DONE. Doesn't even take 10 minutes.

I have no idea yet. We will see on the dyno here soon.

That's where wiring in the E37 PCM for the 2.4 will come in handy ;-) It's got blending tables to run from 100% gasoline to 100% ethanol.

 

whoa. you should check into MAP switching. we do it on the evos, i'm sure it can be done on a cobalt.

 

MAP switching? This isn't an Evo lol. I don't use some tuner in Florida and email him my tunes after I do some logging for him. It takes 45 seconds for me to reflash a new "map" that I have made and saved in my laptop to the PCM. And by that I mean re-write the entire PCM calibration.

 

why not just command the pump on via the HPT scanner?

 

I see you have changed your mind since the last time we talked about this.

So have you noticed a change in your IAT2s? I know you can run a **** load of timing. I keep adding timing and the car just keeps taking it without a problem.

If you changed your stock afr value to 9.7 in HPT did you also change your wideband to read E85 instead of gasoline?
