I did some pre-dyno maintenance/inspection today, for tomorrow. The HPFP looked really clean after ~1,000 miles. This is probably the cleanest it's been since I started running E85 :)

I thought I was screwed afterwards, though. The pump wouldn't build over ~900psi of pressure...turns out I didn't tighten the solenoid down quite far enough. Once that was snug, pressure was fine.

Checked my MAF cal and it's within +-.5% on the high end where it matters. Hopefully this all works out. I'm headed up north in just a while and should be on the rollers first thing in the morning :)

:popcorn:


BTW I think I am an official meth and eth head :) Haven't had time to tune for my 2.5 gallons of corn but the car does love it.

GL on the rollers Phate

I think its time to start looking at MAF volts instead of Load to determine power output. The MAF scaling for corn does indeed skew the load numbers.

injector scaling FTW so we can get back to real load numbers and not have to scale all the tables based on load...right?

Make us proud clint

tapa dat ass

My load hasnt changed like that due to e85. My Gs Is a lil different but thats it. If we went off maf volts it wouldnt take into account maf size. So we would need some kind of scale that dictates power vs volts scaled for each maf size. YOu wanna get that handled for us please. Thanks pimp. lol

What you talking bout willis?

if you scaled your maf up by 1.20 + your larger MAF, your load values are not realistic. Maf Vt may not work either but Load def doesn't work LOL

I'm not a math guy so can't help you on a MAF vt / power conversion there pimpdaddy :)

No results yet?

results are tasty :)

Fixed; oh and update plz kthx?

Phate texted me his numbers from the dyno run. I came.


Tapadatass

What a bunch of cock teasing in here


Tappin

Garbage. phate's next post better be made of Liquid Schwartz. I wanna know them damn results!

tap dat ass?

WTF man. We are waiting... @bewsted I need help on my map, my logs look nothing like yours in load or g/s terms and I am sad.

Who gives a fuck what a maf gs table tells you. Your load tables and maf voltage will tell you all you need to know as well as the dyno. Scaling my maf up is how I got my car to run e85. I know of no other way sukkafish!

Ps. All u gotta do is divide you maf by what ever the % is and you can get a very close # on gs.

1.5 hours from home still...I WILL post results tonight

1.5 hrs.. i'm sure its a 15min drive sir (for you)

Should I just spoil it? it is 300+ / 400+...

hmm.. a lot higher than I expected (285whp)

Quit being such a cock tease you fuck...

id be shocked if he broke 320

That's because my shit runs like a boss lol

tapa dat ass

OK, thanks to all for posting in the last couple hours. I got like 5 hours of sleep last night and the drive home is pretty dull. They kept me entertained :)

So anyway, on to the good stuff - got the car strapped down around 10:30 this morning. It was an absolutely beautiful day, there was almost no correction factor for some of the runs, lol. I made a quick baseline pull and the shop owner/dyno operator (Shawn) was like "uhhhh....something's fucked up, it's not reading right...". I wasn't near the computer so I asked him what the deal was, he said "this thing says you put down over 400ft/lb of torque?!?". LOL, yes it did, 1st pull ;)

I did my first pull with a 12.2:1 (.83 lambda) tune with 1° less timing than what I was running on the street. Here are my starting timing values (2500-6500):
After 19 pulls of throwing more and more timing at it, I ended up with this timing curve (2500-6500):
The top end power just kept climbing little by little, that's what took so many pulls to dial in. The low end could probably withstand a little bit more, but why? I took the timing from 4k-6500 to the point where I lost power. I backed it off by ~1° from where it made no difference, so I'm comfortable with these timing values.

The attached picture "Dyno_Base_Final_Compare_20110828" shows my first pull and the final pull on my .83l tune. I picked up ~20hp over the entire rpm range just by adding timing.

After I got finished up with the .83l tune, I wanted to test some leaner conditions. I hate to say it, but Dustin was right saying it doesn't make much difference. I made a baseline .86l pull with 2.5° less timing than my final .83l tune. Stepped up timing from there in just a few pulls and ended up with an almost identical power curve. The attached picture "Dyno_AFR_Compare_20110828" shows the results of changing the fueling.

____________________

Cliff Notes:

-Car ended with peak hp/torque of 325/425

-Car made 300+ hp starting at ~3900rpm

-Changing AFR's didn't have any significant affect on final power output, even after changing timing.

Attached pics of graphs are SAE correction from a DynoJet. Uncorrected numbers are ~5 less than SAE. It was a near perfect day, today. BAT's were in the 115-125°F range throughout the day. Every run was started with coolant temp ~187-190°F for consistency.

____________________

The car feels pretty darn good. It pulls ssssooooooooo smoothly and of course it feels a little faster than what it did beforehand. The flatness of the power curve really surprised me, but the car is damned fun to drive like this.

Forgot to post this, because someone is bound to ask:

"Mod List":

cpe CAI
Protege Garage TIP
Stainless Works Catless Downpipe
Fidanza Flywheel (LOL)
E85
Sexy tune via Cobb Accessport

Stock parts, just to clarify for those who ask anyway: stock TMIC, stock catback, stock exhaust manifold, stack intake manifold, Autolite XP Stock replacement spark plugs...there isn't much done to it!!!

that is so win phate! :You_Rock_Emoticon:

makes me want to go 100% (once i get FP internals)...

Wow! Good fucking job dude! That timing is crazy! I thought we didn't make much power after your original set up. Does e85 change that or am I just remembering wrong?

I've been waiting all night for this post! Another ko4 faster than my 2871!

edit: That graph is beautiful!

baller.

Christ almighty. New stock turbo records? Lol

PS - for those I texted - my numbers were off because the comp at the shop was set to a different correction factor. I told Shawn I didn't care what the numbers were, as long as I could compare runs. So I was looking at non-SAE #'s for the text, lol. :oops:

But man that is some awesome torque numbers!! Man was i good on my guestimate of HP, BUT im much more a torque person! Nice cliff thats some awesome torque numbers!

phate, we should get togethor some time soon, my new set-up is almost done and i need a few more vital parts, but i would love to do a 50/50 e85 and let you tune my car.

Are you using the fuel pump internals, or the whole fuel pump.

Guess I need to get my ass in gear....:(

Can you post data logs from the dyno pulls?

Bad ass BTW. Makes me want to go dyno now that I have my 3-Bar MAP sensor...

But I guess I need to add some more timing first! :arms:

Also, out of curiosity, by what percentage did you end up scaling your MAF curve for straight E85?

go out and pwn some evos now plz

12pk IIRC he scaled by 20% as a starting point and tweaked from there. You should do 20% of the whole curve then do a MAF cal on 100% E85. Honestly though I dont know if i would jump right into 100% i would start at like 60/40 mix. then 75/25, then 90 / 10 of e85/93 octane. This should limit the gunk going through your system, and make sure no bugs crop up while running the eth

Plus a 90/10 mix will prevent the cold start issues that e85 has. Just be sure to save your 93 tune.....

POW!!!!!!!!!!!!!!!!!!!!

Holy crap timing. I know E85 burns slower so it "needs" more timing, but I never expected to see that much of a difference.

jesus lol

ready to throw some more parts on there? haha

YOu believe me now? LOL

Now imagine with a nice tmic or fmic, DNP manifold, and a nice intake manifold> 350whp. Now peeps see how I was able to dyno 345whp out of a stock turbo srt and how the stock turbo subarus and cobalts are getting 375whp on stock turbo with e85. Mad timing. I put 42 degrees at my bros srt on e85 where it maxed at 30 before e85.

@phate : thanks.

I will be throwing timing at my bitch like no tomorrow now that you did this.

How much boost were you running?

I had to scale my MAF +16% on 50/50 e85/ 93.

I was right about there also.

I'm in Decatur you are in Champaign, mucho dinero to tuneage my automobile /nod

Great numbers and nice looking curve as well. Makes me jealous and want to really take a look at trying to tune in some timing in my map.

BTW, did you ever list your mods anywhere? I don't recall what you have on your car. Also, what boost were you running for these runs? Any data logs from the runs would be great.
