Wedge performance custom tune on Canadian 91+ Meth. I am loving holding almost 17psi at redline. Thoughts on the log?

Log over all look well. See more boost lag than stock but that is what you get if you want more on top (after reviewing my factory logs, this statement in not true, the stage 1 is a tenth second faster to 8.5 psi than stock; granted my stock is 60k miles old). Your map is asking more than your turbo are putting out, not meeting boost target. I would image a tune that is custom would match what your turbo is capable of. It doesn't seem to be effecting log negatively but i want to be meeting boost targets so future me will knows when something is wrong if it doesn't match...

Looks great IMO, i wonder if cylinder 4 isnt getting quite enough meth i saw a small correction in the timing on that one. the rest of it looks great with just 91 and meth!

[sbuchana12]

Thanks guys. I see so many logs on PS2 but not many on PS1.So I thought it might be helpful for anybody looking at this as an option. It totally transforms the car at the top end, as it pulls way harder. Wedge said that look at boost target as more of a ceiling. He does not want to add more WGDC because he said it would take away from how smooth it is currently, and push the turbo past efficiency.

I am using the AEM kit with the large nozzle currently. Its the 1000cc. Should I drop down to the Medium size? Would that atomize better? Any guess on current AWHP?

Looks perfectly fine.

Don't let anyone else tell you differently.

Don't change a thing.

[Turbod]

Looks great for a PS1.

I'll just write my thoughts here since you asked.
Keep in mind I'm not an expert.

It appears to be a good smooth tune but I don't think you're getting the most out of what you have.

1. You're sacrificing low-end for top-end power but this may be necessary for the AEM kit to flow enough meth into cylinders.

2. Overall the torque seems weak throughout the pull.

3. Fuel trim looks great. Not a big deal but AFR is going rich in the upper rpm. Mine's on target of 12.5 throughout the redline.

4. Your WGDC goes pretty high at 6000rpm already. Mine's usually kept at 85% and I rarely see above 90%. A high flow intake inlet should help.

5. IAT and timing corrections look excellent at 9*. Pretty good for Canadian gas. What ratio of water meth mixture are you using?

[sbuchana12]

Hey Supermoon thanks for your input Do you have a stage 1?

Addressing your thoughts:

2: What torque do you think would be right?
4: I have a Pure Inlet
5: I am Running a 50/50 mix

Yes, I have FBO PS1. It's all in my sig.
No right or wrong but in 3rd gear, I normally see 650 to 680nm at clutch from 3500 to 5500rpm. The peak occurs at 4500rpm.
From 5500rpm to 6000rpm, the torque tapers down to 550nm and it stays flat to the redline.
I'm not sure which is "better".
With PS1, you can limit the power in mid-range and carry it over to the redline or make a lot of power in low to mid and let the power fall off past 6k rpm.
The sensation of power through the redline is fun but for daily driving, I find the power in low-end and mid-range is more helpful.
Top-end is what PS2 is better at.

Good thing you got an inlet from Pure. My VRSF inlet sucks. Do you have a stock intake?

Since your tune is dialed in, I wouldn't bother changing the nozzle size or mixture ratio.
But I've seen people getting better results with less water.
Some say straight meth works best for our engine but I recommend 70~80%.

Is Canadian 91 any better than 91ACN? If not, using less boost makes sense.
Steven is from AZ so he should know what's best for you.

[sbuchana12]

Ok perfect. It's good to see another PS1 Car

Canadian 91 is on par with 91ACN or maybe even slightly worse. Our fuel is bad up here. I do have a stock intake as I heard that an aftermarket one does not do much except for sound so I didn't bother with it.

And damn you are like double my torque at clutch lol. Must feel pretty fun. Do you have any logs I could look at? I am curious on what yours look like what fuel are you running?

Cheers.

I use 97 RON ethanol free gas which is rougly equivalent to 92 US octane.
I pm'd you my log.

[sbuchana12]

Log looks good, 20psi would be fun in the mid for sure! I wonder why I am not hitting the 18.5 target for me?

Is your rail pressure a bit low throughout the run? And your timing seems lower than mine. You are 5-6 constant but I am hitting 9-10 at the same mid-top end?

From what I understand, if you're targetting a lower load and if the turbo didn't have to work hard for it, you won't be hitting the boost target even if you don't have any hardware issues.

The map was made for pump gas only that's why the timing advance was limited to 5*. New map is in the works.

With limited octane, you can either use more boost and less timing advance or use less boost and more timing advance. The earlier will yield more power and the later will be more efficient. Timing advance past 10~12 degrees doesn't yield much increase in power from what I heard.

Rail pressure at 2200 psi isn't "low". It's always been a normal value since MHD was released but a new table to override the rotary HPFP was recently found so a tuner can now choose to get it up to 3000psi.

Using a higher pressure would yield better fuel atomization and can provide more volume, especially for E85 mix but I worry it might wear down the pump faster.
My gas is ethanol free so there's no reason to make the pump run harder and I don't want any unknown side effects.

What year is your car? 2012 or 2013? You will never hit your boost target on the Wedge tune because that's not how it was intended with how he set it up. You may have the plunger style HPFP that cannot flow as much as Supermoon's rotory style HPFP. That may be a reason not to give you as much boost mid range. Another possibility is smoothness of the map. You will want a larger turbo if you feel the rush of torque and then it fall off up top. This should feel smooth and consistent throughout your pull.

[sbuchana12]

Ok thanks Supermooon.

Turbod my car is a 2011. And it does feel smooth throughout the pull for sure.

@ Superman,

"Good thing you got an inlet from Pure. My VRSF inlet sucks. Do you have a stock intake?"

Why do you say that? A tube is a tube is a tube? The same diameter and metal?

They tried to copy Pure inlet for cheap but they didn't get the fitment right.
The mounting points didn't line up correctly.
They should've drilled a much larger hole for the stock rubber grommet.
I kept tightening the bolt and of course, it broke because the pipe doesn't fit.
I can't get a drill in there so I have to live with a stuck bolt in the cylinder head.

Other than that, the machined grooves for the o-ring were wider than the o-rings unlike Pure's.
Didn't come powder coated so it's obviously false advertising but they keep using the picture.
O-rings started melting a bit after a few months so I asked for replacement (not for free).
Got a reply after a month: "We don't have the o-rings available for sale separately but I'll do my best to get them in stock ASAP."
It's been a year now and I don't see any update on their website.
I got the o-ring specs from Pure and ordered from McMaster Carr (25 o-rings a pack for $10 + shipping).

[maxihari]

hmm
that makes me feel uneasy about my upcoming installation of the turbo and VRSF inlet pipe.

Did you talk to them about it?
