so i raced 09cobaltss1 before i added meth. we were dead even (maybe a half car by him.
(mods trifecta tunes 24 psi both cars. only difference i had a hahn ic and him on the stock ic).
The night after i installed the meth kit i raced the same car again and nothing changed at all.WTF. I changed my normal trifecta tune (23.5 psi, 12.1 a/f ratio, 14 degrees of timing) to byt/tf tune 26 psi, 19 degrees of timing, 13.0 a/f ratio. with basically no results.
-I had cel for bpv (p2261) and the rear o2 sensor.
-Also, i drove the car hard the whole day then stright to racing him. IDK if oil temps were sky rocketed and i had another 300 lbs on him with the other passanger plus me.
-the diaprham on the inside of the bpv is ripped. and the tuner byt said that is the problem.
im just really confused whats going on. I read on here other people having issues with boost leaks while adding the meth. the diaphram is on national back order and **** sucks right now.
i wanna solve this.

If the BPV diaphram is ripped you have a good sized boost leak. That will cause power loss.
Dont get your panties in a bunch Nick. So secretive all of a sudden LOL.

I dont think everyone can open those logs Nick :P Need software for that LOL. I guess they could post screenshots. BTW did you ever figure out your misfire issue?
I still haven't figured it out, I really don't get it lol. I have the car running a 18psi tune now and it's fine. Im leaning toward fuel related now since Ive exhausted the spark side LOL!! I guess I need to take the pump out and see if the sock is clogged up somehow :shrugs:

This was happening before I even tried the TF tune. Ive tried running a straight HP Tune alone since and it changed nothing. The DI FP seems to rise with either tune as I near 6k to about 2300psi. Then it starts the misfire crap. Maybe my High Pres. pump is messed up somehow? lol. IDK..

First things first get the BPV fixed. Then have nick retune it for the higher concentration of meth because yes it is going to change things. More meth being injected means the STFTs will be more negative as the ECM pulls the IPW back to keep the A/F at the commanded lambda value. More meth can mean more timing can be run safely in most cases as well.

You can but if you are on 93 octane I do not see it being much benefit going over 70% meth. If you are at 30% right now it should make a difference. The SC balts need the extra water to help cool their IATs off. Our cars run as much as 60* cooler to begin with.
Sorry, but some people should not really be messing with meth if they don't even know what mixtures to run on their car
Learn about it FIRST and then install it.
Not trying to be a dick, but so much ignorance around these forums and then the tuners get questions like OMG, my turn signal light is blinking faster, is that because of the tune?
or you made my clutch slip, I'm pissed.
You want power, you gotta pay to play.
Layman's terms here people.

I've tuned for meth on STI/Legacy GT, and it wasn't too hard, but this car seems like it would be very finicky.

Does this car ever truly operate in open loop w/o feedback from the WB O2 sensor? Seems like tuning meth on this car would be a bitch compared to cars that operate in open loop at some point.

Under normal conditions no unless the calculated airloads exceed approx 270%. It can be a PITA because the ECM is constantly pulling back the IPW to try to keep the A/F at the commanded lambda value. With the methanol we want it richer but the ECM says effffff yoooooouuuuuuuu.

With the methanol we want it richer but the ECM says effffff yoooooouuuuuuuu. You can adjust the PE lambda values to make it richer. Seems easier to tune for ethanol in the gas than methanol being injected into the intake.
