991.2 Cobb Accessport, post your results
#571
@PTS-BRG @4 Point 0 Problem is fixed fellas no more shifting head aches on the 911.2. After several test last night the car is moving sweet and no problems car ran multiple 7.5 60-130 time without an issue.
It feels super strong and i think i can do better but with 100 degree ambient temps on a car without intercoolers lol we cant ask for more. I will try a 1/4 mile run today to see what she can trap.
I will add this was done on MS109 fuel 1/4 tank on a car with Soul Cat Deletes
Special thanks to @M Engineering Mitch you are the man! thank you for putting up with my bull**** and 10000000 text messages LOL!!!
Now on to the E85

109 OCT is about the same results as E85. Nabil out of curiosity, I too run catless pipes. APR says there isnt power to be mode from catless, have you found that the Cobb AP + Mitches tune made more if any power going catless?

You keep saying this, but Stoich for gasoline is 14.7 and that is LEAN when you're actually trying to make power.
At wide open throttle, you need to run rich to prevent detonation.
I think whoever explained to you what stoich is did it incorrectly, or at least your take away was.
Can a tuner jump in here?
From Summit racing:
"It might sound like stoich is always the goal. That isn’t the case. Maximum power is usually found with a slightly rich mixture. Drivability is better at a cruise rpm with a slightly lean mixture. Idle tends to be better with a slightly lean mixture too but a big cam will idle better slightly rich."

Stoich is a race term abbrev when you have it perfect. You are correct that Stoichiometric value of pump gas is 14.7. ‘My point was E85 is 9.6. If you just fill with E85, you go lean and bang.
Sometimes too much information looses everyone. Baby steps.
Grear news Nabil.
Good Job Mitch.

Meaning two cars both might top out at 500hp, but the carless one had a much higher torque in mid range.

Happy we got the car to where it is and I am glad we sorted the shifting issue. Now onto E85 to do the same thing, which should be easy.
If anyone would like to get protuned let us know. We don't do a lot of "e-tuning" so this wont be a forever thing as our development schedule keeps us busy, but we can get some folks in for now.
4.0 I will respond to your emails today, I didn't forget I just wanted to get Nabil sorted out.
I think that these cars can go faster. Nabil ran this in Miami which is basically the surface of the sun. We shall see.
info@m-engineering.us and we can work with you if you are on an AP and would like to get protuned.
@spdracerut I see you and I hope all is well my friend!
Nice to be back doing Porsche stuff. We did a GT2RS last night on bigger turbos, and needless to say it is a monster.

Hook a brother up Mitch. As for mods, I have all of them. : )

Drove for about 4 hrs today after getting tuned by Mitch....
This car is sooooo nice now
Cobb
Kline
Soul
Mitch tune
Fast AF....
And a Targa with manual transmission.... Such a great everyday car.
Interested to see how it hangs with the GT3s, GT3rs, and GT2rs now. I know it's heavy. And suspension is soft, but it moves!

I am happy with my tune.
Here is my concern with changing tunes to Mitch or APR.
The obvious one is, it is most likely slower than my car is now. Why do I say that? Because no one has come out and said, “We found the torque limit table that was causing the issue, and we raised that limit. So now we are free to add power.” That to me is the issue fixed.
Not we no longer have the problem.
That indicates to me they have reduced either the total torque, or the rate at which it ramps up, so as not to trigger that table. If they have done this, then there will be instances where the car will be slower than it is now. I do not want that. I would prefer to live with the problem, than to reduce power.
No matter how fancily they want to skirt around the issue.
Its a straight forward question. If you have found the table that is causing the limits, and have access to it and have increased it, awesome, let’s go.
If you’re just leaving it in place, and reducing things so it is not triggered, than I’m not interested.

We sorted out the issue, we didn't reduce power hence Nabil just trapping 133mph on the street in Miami heat. Now we also have E85 maps sorted so looking forward to doing more of those. We are working with each customer to make sure there car not only works, but are also happy.
