Fixed!

I bet with 370cc injectors, the car wouldve ran a lot better but might not have run better that 93 octane since there are no other mods on the car... idk.

Lack fo station of E85 is true, here in Chicago it's a little bit more common now then it was. But now days it's not that hard to have two maps and switch between them depending on whats available.

As for the 370cc injectors, yeah sure the car would have ran a lot better with 370's untuned on on NA, but thats cause they would spray about 35% more fuel which is needed for E85 to burn properly.

As for performance you wouldn't really see any, just a lot more gas consumption LOL.

Any one have a idea on how much mpg i will lose. I am getting 30mpg now and i figured 25mpg on e85 since you are supposed to run about 15 to 20% more fuel during cruising and 30% more at WOT. Its a honda so there is no point in going WOT. ..lol

Just my way of saying F you to big oil.

Truth is Treason in the Kingdom of Lies - Ron Paul

Tune it with crome. At full throttle, you need to bump the volume up by 30%, but at part throttle, the higher octane allows you to run leaner safely, so you can cut that down to only about 15% at part throttle.

Ask for directions to soapland, bring about Y50000 and don't take your mom.

Yeah i thought you only had to do 15% at part throttle but have heard different things hear and there so....My wide band only shows afr for gasoline so i will just tune for 14.7 at cruising speeds and probably 12-11afr under load just to make it safe. If fuel consumption only goes up 15% i should still be getting 25mpg ...

I will defintally look into the propane thing. I remember seeing a propane datsun for sale on one of the local forums a while ago.

In the end i just want to give the middle finger to the oil companies

(I know that smilie is just waving no no but, just consider it a middle finger to the oil companies for now.)

i have an enthalpy tune for 370's, n60 maf
now to run e85, i can just plop in 480's and go? (370*1.3=481 iirc)
are the ignition maps the same for gas and e85 (or at least very close?)

i also have an safc2 so im thinking of doing 550's and upping the boost to near 300hp reliably on stock block. my question is how big of injectors will safc control? everyone always says 550/no bigger than 680/whatever... will the enthalpy tune allow me to get 740's/820's on e85 so i dont have to buy more injectors when i rebuild my motor(eventually) or would the idle be crappy with a big cruising mpg loss? how big would you guys go?

^_^

His whole fuel system is probably filled with this stuff.

the gas in my 240 has been sitting for about 5 months but i put some stabil in it before i stored it. Even though i did i wont get on it until i get some frest gas in there. I just dont want the old gas to clog up the injectors.

WD:

Do you drain out the gas before you store it or just drive it year around?

Has worked for me so far.

Some of you may know i tune for and always recommend e85 if you have it locally.. there are a few things i tell everyone when converting over to e85

First thing you need is a wideband, it is very very important... i browse through this thread and see people knocking e85 saying it made their motor sound weird.. thats because you're burning a 19:1 afr you need more fuel.. approx 32% more

second thing you need is either a good retune or a alcohol tolerant FPR (e.g. aeromototive)
after a few tanks of e85 you will need to change your fuel filter as all the crap built up in your tank will clean out and accumulate in it remember e85 is a solvent and will clean out all the deposits

now your car should run good.. now comes the tuning part (recommeded) for low throttle you want to tune to around 14.7:1 afr (gas scale) but WOT on boosted motors i have found out that 13:1 afr is about ideal when running e85.. higher octane allows you to run leaner safely

if you guys have any other questions about converting over to ethanol please dont hesitate to email/message me

I tune KA(T)/SR/RB/VG/CA18's! Fast shipping and best price! many references.
I also sell consult cables!

when you say "Great for smog" what exactly do you mean.

Run it on pure E85 or mix gas and E85 for the test.

I'd like to know because I have to pass smog in a few months and I know my 240 won't without a wink and a handshake

hit up my email if you don't want to discuss it on the boards

So in your opinion can I buy 33% larger injectors (555 -> 740), adjust the FPR to get the proper AFR and call it a day? Would I want to advance my timing a degree or two? I know that it's not ideal for daily driving, but I would just be running rich which isn't horrible.

Specs : fully built SR, upgraded turbo, Enthalpy tune, Tomei FPR, Walboro 255 pump

I have a quick question though. When he tuned it he disabled the stock o2 sensor but, i made him re-enable it before he burned my final chip. I wanted to keep it for small changes in the weather such as air temp. and humidity. He said that if i run the o2 sensor it will make me run lean because of the difference between gas and e85 afr's, but since the o2 sensor is searching for 1 lamba that would be the correct whether its e85 or gas right?

*EDIT*

Sorry we're talking idle, 1 is on the money for stoich. Is the ECU MAP or MAF...MAP huh...hate you.

Some guy was talking about using HHO gas system or some thing like that in the 240sx general section. It caught my interest because of how simple the setup is. That might be something for me to look into instead or running the e85.....or even better.....use them both. Pay 2.70 for e85 while still getting regular gas mpg.

they want 50$ for a how to manual but, i suspect i can find out how to make a system for free if i search.

LEMHEAD16 --- exactly what WDRacing said, it releases less HC and burns cooler than gas so it does not release as much NOX

drape123 I want to know your opinion. E85 is about $1 cheaper per gallon than premium here and we have about 5 stations in my city that sell it at a wide variety of prices. So in your opinion can I buy 33% larger injectors (555 -> 740), adjust the FPR to get the proper AFR and call it a day? Would I want to advance my timing a degree or two?

Correct if you have a tune set for 550's you can run 740s and your car should run OK.. or what i tell a lot of 240 owners just throw some 370cc injectors in there.. that will run great and will actually lean you out a little bit on the stock computer which is GOOD for power since E85 has a higher octane.

one thing you might notice on a stock ecu though is cold starts suck... the car will misfire until it gets warm.. that is because you really need to advance the timing 7 degrees on the Cold start map because again it burns cooler and has a higher octane

If you'd like me to send you a retune for your enthalpy ecu for e85 lmk.. i can also tune it for SARD 850cc injectors which are the biggest sidefeeds available and cheaper than deatschwerks (and sard are brand new)

You can't just "run" E85. You need a way to increase the fuel flow, since E85 requires roughly 30% more fuel then pump gas does.

True, you can either turn the fuel pressure up or get larger injectors.. for a NA car looking for a few extra HP you can drop in 370cc injectors and advance the timing 5 degrees and call it a day.. other than that you need a retune.

hope this helps out

In a 2006 Accord I did run E85 with no problems, no alterations, exept the check engine light kept tripping due to the O2 sensor. But aside from that the car started, ran just fine for the couple months I did it until E85 and regular gas got too close in price to justify the use of E85.

I never researched it, but how much can the stock injectors increase flow on their own?

I'm looking at going with some E85. I'd like to get some new chips from you Jay. Then swap for when I feel froggy.

I also need to install the 3076r. Probably this weekend.

Werd 'em up

I think I smell some popcorn

EDIT: $475 shipped from EAT. Badass!

The close e85 station prices suck (3.60) but, if i make a 15-20min drive i can get it for 2.76 ......

EDIT:

The only mod i plan to do other than the injectors and tune would be to replace all the fuel line with new. Does e85 have any adverse affects on wideband o2 sensors...like a shorter life span?

Also, how much timing should i add in the cruising loads? I dont have a knock sensor so i was thinking 3 degress would be good and for under boost i would just leave the stock timing (only 6-8psi).

Opinions welcome......jason and WD

Um, running higher octane fuel has NO added benefits unless you increase boost or timing. Especially since you're going to be burning more fuel then compared to pump since the soich of E85 is about 30% richer.

WD

My friend and me went as far as going to 14psi on stock timing with e85, and had no detonation at all.

My guess would be anywhere after 14psi thats also depending which turbo you use.

We are using a Precision GT32. We haven't gone over 14psi on stock timing he has been driving like this for a couple months now. But I think that up to 14psi on that turbo stock timing is fine, and see very nice gains.

After that you might need to monitor timing closely and start pulling but I'm sure it wouldn't have to be much.

yeah E85 is miracle fuel. im running 16 degrees total timing up top at 30+ psi no detonation on a gt35
