Drivers attempt at E85

To an extent. It changes based off how much you have scaled it. Ive scaled mine 12%. I was seeing about 290-300gs on pump. Then it went up to about about 30-40gs after than and Ive turned up the wick on my tune since. Ill post logs and such soon. Either way car is ripping and numbers are numbers. I wanna see what that damn dyno and track says. With about 330gs the car trapped 115 so you do all the math and figure it out for me lol.

[driver311]

Played with my tune a touch more. Richened up a touch and added a lil bit of timing. 390-400gs from 5k up. Car is handling business.

400/1.12 = 357 g/s.

That is around 47 lbs/min of flow, which is about all one can expect from your 3071 (unless ATP doesn't use the 56 trim).

[driver311]

I have a 3076r

Edit: Posted response same time.

[driver311]

Here is a few log from today. 22psi feels good

[bewsted]

Your AFR's are all over the place.

Wonder why?

[driver311]

Well they range from 11.7-12.0 really. YOur just over analyzing it. When I first shift it goes a lil leaner but no big deal. Im cool with anything under 12.5 and over 11.5. In fact this map my afr is set at 11.9 and I have been running 12.3. Ill probably lean it back out some. What matter is im in a safe range, fuel trims are good, power is great, and no knock. Remember we are dealing with a different fuel here that doesnt burn like pump gas. ON pump or race gas my afrs are a straight line across. This is still a work in progress. Im happy and car feels insane. Im loving it.
I am maxing my fuel system out over 22psi though. At 21psi I see about 90% duty cycle. So I might take my % back a touch. Maybe run 40% e85 and see if I can stick with 22psi. We will see.

Anthony, you should pull the solenoid apart some time if your bored, and give it a once through like Phate has several times. I'm sure he could walk you through it.

I'd be curious to see if it's dirty, and if so, if cleaning would help stabilize the afr's.

[driver311]

Ill check that out. Thanks

Just loaded a new map with 12.2 afr raised fp a touch. Im gonna take some more logs and see what happens. Ill post that up.

[driver311]

Here is another with a lil less boost.

[pearl_ms3]

sure wish my car was that fast.....

I checked my pump after like 5 fill ups. I had such a small amount of residue it was hard to even notice.

I guess I need to pull that solenoid apart too huh?

So when you going back to the track man....Interested in seeing what you get on vs the last time.

[driver311]

It feels pretty good for sure. I just need to figure out how to get my timing to hold where I have it set. Im requesting 14.5 degrees and only seeing 11.5?

[Babyface]

Wow, now I just wish they had E85 around here............

I was going to ask why you lowered timing but I figured you had a reason.....

The only issue I have is maxing out WGDC. Can't get anything about 93 or 94 above 5500 rpms.

So have some issues holding above 5500 rpms....Guess i should check for vacuum leaks too.

Do a e85 search in your area. Its there somewhere, it has to be. CArs run off the shit you know. LOL

[bewsted]

Have you ever fucked with your max tables? Maybe Your hitting over the set max timing?

[driver311]

Ive been running that much timing for along time with no issues. Its just since I went past 2.2ish load. Its like its still trending down as load climbs. I have it set high. IM not sure. Dustin is gonna look at my map. I thought I had it propa but Im not always right. LOL

[phate]

Man, I'm seeing >3.6 load @ ~3k rpm and >2.5 load @ 6k. I would check the max tables and whatnot.

[driver311]

what table exactly. cause my commanded wot ol table is asking for 15 max?

So you must be on straight e85 to be seeing those kind of loads. Im running a 3076r at 22psi and on 50% e85 and see nothing near that. LOL

[phate]

It's like a "max ignition" something or other table. It's at the bottom of the ignition tables, if I remember correctly. It's an absolute limit that limits both CL and OL timing, no matter what they are commanding.

I made a post a while back about a leaner spike right when I go full throttle. AFRs also seem to wander .3 to .4 or so from targets in the lower RPMS at WOT. Past 5k they stick right at 12.2 or so (targeted). I am currently running 45% E-85. Could the E85 be causing slight fluctuations in the AFR? I remember logs from before I ran E85 and that shit was like a laser it was soo straight. Also how lean do your AFRs go? I hit 13.0 when I was targeting 12.3 once and backed the AFRs way off in the RPM range to lessen the initial spike from 3-4k at WOT. Car didn't knock once even when it hit 13.0.

[bewsted]

The way I cure that is lower my target at the point in which it spikes too match what I am running past that particular cell.

If your targetting 12.0 @ 3500 RPM BUT hitting 12.4......Try lowering your target down to say 11.8 or so and see what happens.

On the subject of load I seen 2.68 today which made me go HOLY SHIT lol....

[driver311]

Probably is the gas but Im not worried about it. Just wanna get my timing set and just stick with 20psi on street and when I go to track Ill run 22-23psi. Should be more than enough to hit 440whp on track and dyno and rock some 11s with ease. Thats all I want at this point. Im playing with fire trying to go farther. We have already come so far in last 6months with these cars and tuning. Cobb has been awesome and opened lots of doors for us. Im just happy that we are finally getting the results we always knew these cars had in them.

Dyno soon boys and 11s soon to follow. YOu can mark my words. I was already so close to 11s with wayyyyyy less power. LOL

[bewsted]

I am really hoping to make some good power saturday....

Would be nice to see those 11s on our boards couldn't agree more.

Yea thats what I am doing. Mine is weird though. I target 11.8 at 3000-4000 and then 12.2 from there up. In reality I will still see spikes up to 12.4 sometimes in that range and sometimes I see as low as 11.8. After that in the RPM range the AFRs smooth out. It doesn't really bother me as long as I don't see knock.

Fuck I need a bigger turbo.

[djuosnteisn]

I still see the lean spike on a few cars.... no clue how to fix it at this point. It's a transition thing IMO.... dunno. Never see knock there though.

Wonder if it's something hardware related, like slow 02 sensor or something.

[driver311]

Im sure thats exactly it dustin.

If both of you OL ignition tables are the same, then it is most likely the max ignition tables.

I just copy my entire OL ignition table starting at 0.31 load into my max tables.

[bewsted]

Shouldn't the only thing that matters be anything above your lowest load at WOT?

Just saying.

Maybe pu's have something different I only have 1 OL table

[11cruzito11]

[QUOTE=driver311;929317]Ok some updates. Car has a new turbo. Im currently running atps new ewg back half 3076r.

When you say your running ATPs new EWG back half 3076r, are you talking about this below:

Externally Wastgated Turbine Housing for Mazdspeed 3 - GT3071R/GT3076R : atpturbo.com

[bewsted]

That is the balls....eliminates the need for a different exhaust mani... im assuming there is no wastegate clearance issues?

[djuosnteisn]

Doesn't seem to be, that's what driver's running. Looks trick.

[Dano]

Anthony....post up a pic of that EWG housing setup.

nevermind...too much trouble to see down there anyway.

[djuosnteisn]

Hahaha, i have one he sent me a while back, lemme see if i can upload it, hang on.

[djuosnteisn]

*edit*, i've emptied my in box since then.

[Enki]

I'll refill your box.

[11cruzito11]

So can you confirm he is running that housing?

I want to use that housing and wasn't sure if anyone was running it.

[driver311]

Yes im running it and it works pretty efffing slick. Clears perfect. All you need is a small dump tube made and your set. I was thinking about talking my good buddy austin to get it for his 3071 setup so he can get rid of his boost spikes and get that sick ass sound you get from this tial wg. Im loving it.
