I was curious if anyone can tell me what all id need to replace to switch over to E-85. I thought i saw a thread somewhere about someone doing this but i couldnt find it when i searched. If someone has done this your input would be greatly appreciated!

 

U can't do ful e85 I think I'm not a 100% because our injectors. I'm looking I.to doing this as well but our injectors wilk go pass 100% duty cycle I think on ful e85 not 100% sure

 

I think matt and ZZP were experimenting with an intake mani that uses another injector per cylinder so you can run straight e85. Maybe they will chime in and let you know.

 

Vince can tune for it.

 

Vince can raise fuel pressure but can not safely tune e85 because duty.cycle of the injectors...

 

70% ethanol was about my limit, but I just found a lingering injector issue that may have been hurting me. (No seal on #3 from the factory) TF 2800 psi fuel pressure and that was as far as I could push it but I'm pretty well bolted up.

Stock you can run it, Gimp did, but you will have starting issues under about 50* f. Takes a double shot prime.

 

Hey iambroke I read u had issues spitting and sputtering. I have kr, and misfires on #3 but random on 4 ..... if I get on it about 4k rpm in second all I do is misfire and sput and shiz. If. Boost more then 20 sometimes I do it more often. My tune is good. Maf is 100% and dals is 100 my torque maps are good and same with over boost. I'm just seeing if u reconize my issue ol.

 

Mine was missing a teflon seal on #3 injector, compression was 10# lower on #3 from day one. I would break up under load from 2k to 4k though, fine above that. Lots of blowback on #3 injector body after 50k miles. Glad I found the issue finally. Funny thing was it didn't get really bad unil 50k miles. Must have finally blown out the fitment on a pull.

 

Your tune needs big changes to run a E-85 mix. IMHO a 50/50 mix of E-85 and gas works really well without maxing out the injectors. Heck if you are still running the timing you were running on 93 octane where you lived before you have major knock right now I guarantee it. That 91 octane you are running now will not tolerate more that 13-14* max timing and I bet you are running about 4* more than that.

 

yes a mix of e85 will make a big difference im running 50/50 mix of 91 and e85

 

Yeah i know i deff need a re-tune. Ill more than likely be hitting you up once i get my student loan. lol! I havent thrown any check engine lights or anything since i got out here tho, wouldnt i get a code if i was knocking? Im just really interested in going with E-85, and since i need a retune i was thinking about going with e-85, i wouldnt mind a 50/50 mix either.

 

How exactly do you mix the e-85 and 91 to 50/50? may be a stupid question but im just curious. lol!

 

what ever you put in of 91 you have to match that with e85, example 4 gallons of 91 4 gallons of e85

 

yeah i knew it was a stupid question! lmao!! idk why i couldnt think of that?

 

Im running 50/50 e85 and love it. car runs awsome... so awsome i burnt up my stock clutch with just a intake and exhaust doing 3rd gear pulls lol. Stage 3 clutchmasters sitting in the garage though

 

DAMN! LNF swap...kudos man!


Has anyone seen a measurable difference on the dyno running 50/50?

 

what trans and clutch were you running.

 

The stock LNF tranny and clutch. I would say about a 40ftlb gain in torque maybe 15-20 gain in horsepower more than enough to feel though. The E helps alot with EGT's so it helps keep everything a little cooler. My car actually runs smoother with it but my E tune has many many hours of tuning behind it, may be the reason for it running so much better.

 

Bump for answers!!! lol

 

Yes, one car I did saw 30whp and 30 wrtq gains on a mustang dyno with the same boost levels just adjusted timing, MAF and PE lambda.

 

No you will not get a code for knock. Take it very easy on your car for now until you get it retuned. There is a huge difference in knock resistance between 93 octane and that 91 octane you guys have.

 

Very nice! I think my question should have been. Has anyone seen any performance increases (measurable) with a BONE-STOCK SS/TC running 50/50?

 

With 10* peak timing and 15psi I doubt you would see any performance increase on a stock tuned car. No one has ever dynoed before and after on a stock tune though.

 

Thanks for the info.

 

Oops... too late for that. well i take it easy from now on. Ive also hooked a scan tool up and nothing came up for knocking or missfiring. I do plan on getting a retune soon tho.
