^^^I like to hear that

I also had a weird thought...Since Ethanol burns cleaner than regular gas to the best of my knowledge, would it be possible for one to pass an E test while being catless running full E or even part E?

 

Maybe. E-100 would pass IMHO.

 

Hmmm...I'll have to experiment with this thought in October when I've gotta get my test done. That would be straight awesome if it worked

 

In my state, they look for the cat under the car and check the OBDII, no sniff unless it's older. Pre '99 I think.

 

Hmm that may be how mine is too...because the last time I went with my '02 Blazer they didn't run it they just hooked up the OBDII and told me I was good.


I'd still love them to run it just to see

 

LOL haha yea that was a 50/50 mix with e85 and 91 octane. No wonder why my car threw a low rail pressure code before we went to straight hptune. I hope what you are saying is good lol this whole fuel injection system crap in new to me... I'm so used to tuning a carburetor.

 

Yeah your car is a freaking torque monster 330% airloads on E-47 is unheard of IMHO. You are seeing 45% IDC right now with 12.9 mS IPW at 0.883 PE lambda.
I can carb tune as well. I have a WB on my Polaris Outlaw 525 so I can tune it.

 

LOL torque monster... yea I know tell that to my tires and the V-8s I embarrass from time to time.

This is what I looked like when reading that-------->


Haha a wideband on a quad thats awesome, I never thought of that... I always just arm dynoed my stuff... if I couldn't feel my shoulders getting pulled out of the sockets it wasn't fast enough! haha retune for race gas!

 

Yep I run 12.6-13.0 A/F on the quad just like the cars I tune LOL. End thread jack.

 

You still have a low rail pressure issue on E-47. That last file I sent I advanced the injection timing to ~325 to 339* BTDC. I hope it helps if not you might need to back it down to 2 parts 91 octane to 1 part E-85.

Your car makes too much low end torque for the HPFP to keep up on E-47 LOL. You really should try to mod the HPFP if you know of a diesel shop that could bore it out and put a larger piston in it.

 

^^^^^^ Looks like mine on E85.

 

That is his car on E-47. RYRO14s car did the same thing on E-47. His car (RYRIDESMOTOX) made 370 wrtq on a mustang dyno on 91 octane and 5-7* of midrange timing.

 

Well, got my first taste of the corn tonight. Went out to do some logs. All I have to say is *&%%$ *&%# &^@#!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I <3 corn

 

welcome to the e85, methanol injection club. im running a 7gph nozzel since i bolted the 5857 turbo

 

koooooooooooooooorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrnnn nnnnnnnnnnnnnn

 

5 gpm nozzle on the stock turbo when the pressure switch arrives, everything else is ready.

I'll try and snap some pics when I pull the headlight out to finish it up for Gremlin. Prob be Mon or Tues.

 

LOL too much torque... damn, that sounds like a personal problem haha. I have been looking around for a diesel shop and I found one. I'l call this week and see if they can do some adjust of the HPFP. I logged the new tune. It still drops pressure but it only does it on the second pull, not before, not after lol

 

For those that may ever need to switch back and forth:

Had to go on a 5+ hour drive trip up north and back a while back, to an area that didn't have much E85 around, so I decided on switching to gas for the trip and then switching back once I got back...

Tip: After running the car down on gas or E85, fill up and drive around for 5-10mins BEFORE flashing the tune, or the car will hate you.

The first switch back to 93, I ran the tank almost empty, filled up, rolled the car back, and flashed it right then. The car wanted no part of things until it got into closed loop, and still pretty much ran funky until it was most of the way through the fuel transition in the fueling system. I secretly blame it on the car becoming an E junky.

Knowing this, when switching back to E85, I did the flash after some driving and my trims started shifting, and it was a smooth, seamless transition.

I know not everybody has fuel trim monitoring capabilities, so just give it 5-10mins of easy driving to get the juices flowing before doing the flash. I would also recommend keeping out of boost during the transition period as well, for the sake of the engine.

Anyway, just wanted to clarify any questions people may have had about the order of things during switches back and forth.

 

so why is it that I have to prime my car on the cold start with the E85? Is it cause the the E85 or the tune that makes is hard to start? Once I get the car started she runs like A champ.

 

I don't have a idle or starting issue at all. But I have read that E does respond unfavorably to chilly mornings.

 

Does the MAF scaling alter the MPG INSTANT readings at all? I mean I don't think it would buuut I'm seeing noticeably better gas mileage running E47.

 

Injector constant increase raises MPG displayed for whatever reason. No way to scale it into the BCM. I informed Vince of this during testing of the E85 layer tune.

 

Oh darn

Even still, I don't think I have seen a drop in gas mileage thus far. Seems pretty much the same based on fill-ups and manual calculation.

 

a little late but subd

 

my mileage test is on! i got a 350 mile trip to Houston on e85. last time i made it from Edinburg, Tx to Buckeys Truck stop thats outside of Houston with 1/4 tank to spare on 93. gonna see how far i make it on e85. im taking an extra 5 gallon jug of e85 just to make sure.
