Bedtime Story
So I went to Auto Zone (about 5 miles from my house) to pickup a couple of front brake rotor for my mom’s Suzuki Esteem. Coming back a young dude driving his very clean and very hipped flaming yellow Cobalt SS passed me on the right turning lane and stomps on the gas to show me that he is the man. I decided that it was not worth the gas/meth and just let him go.
Later a mile down the road I catch up to him at a red light (I’m behind the Cobalt SS) and I then realize Mr. Slick got his girlfriend with him and I can see that he is talking to her while staring at my RX8 from his rear view mirror. I know what he is thinking “there it is, another slowpoke RX8 and if I smoke him like I have smoke other RX8s in the past, it will be a definitive score with my girl tonight”. Then I heard my son sitting in the passenger side. “Dad…kill it.” Well, I can't disappoint my son (he is another rotor head). Next thing I do is to disable the traction control and turn the meth on.
So it goes like this. Light turns green, Cobalt SS takes off like bad out of hell. I let him go…then I smash the gas pedal…second gear I’m almost next to him…third gear…where did he go? Got of the throttle and a second or two later there he is next to me looking at my RX8 with what I can simply describe as a WTF face.
So next red light and side-by-side. Light turns green and the Cobalt SS doesn’t even try. My blinkers on and Cobalt SS dude is doomed to watch a girly movie tonight in order to save face with his girlfriend.
I love my Pettit Racing Super Charged RX8.

Pettit versus Cobb AP ReFlash Comparison
I’ve not been on the forum lately but I was told that someone is offering a ReFlash for the Pettit Supercharger using the Cobb AP. I was able to do a back to back comparison between the EFIDude and Cobb tools on a normally aspirated car and learned a lot from the process. I would be interested in participating in evaluating the Cobb AP Supercharger flash as well.
I know $695 or so is a lot just to try another reflash option so I would be willing to provide an EFIDude ProLogger to log data during the comparison and the dyno time necessary to properly evaluate the Pettit and Cobb solutions. Perhaps the AP dealer will loan us an AP for the comparison and let the owner buy it if he likes it. Either way, the owner can keep the ProLogger as my thanks for letting me be involved in the evaluation. It is a neat little tool for logging data and is the exact same tool Cam uses to do all his development work. You can download the software for free at www.EFIDude.com and I am certain we can find a sample Supercharger data file for you to view if you have not already seen the tool in action. You can also get a reflasher option for the EFIDude tool so you can take advantage of Cam's file updates via email. The man is relentless in his development and always provides file updates for free!
I will also ask Cam to attend the dyno runs to make sure the Cobb ReFlash is acceptable to him from a mixture and timing standpoint as well as making sure his Supercharger kit is running as designed.
I will post the dyno results and data so others that may be considering the AP option will have some data to evaluate before making a purchasing decision. It is always nice to see exactly what your money buys before you spend it along with getting Cam’s opinion on how the stuff affects his kits.
Please feel free to PM me if you have any questions or if I can be of any assistance. I’ve tried to stay off the forum as much as possible to keep threads on topic and away from meaningless personal chatter (which I seem to attract a lot of, sorry).
Thanks, Lola

Lola, who would be making the SC tune with the AP?? All you mentioned was a providing a datalogging capability. I'm not positive, but i'm pretty sure the only people who can make AP maps are those few whom COBB have given their tuning software to.

Its already done. The car has been running around since Monday.
I actually had that tune "in the can" two weeks ago.
I'll have a 4-port auto Pettit flash out there on Monday the 31st as well.
I'm not totally sure what Lola is talking about, however. (Unless he is planning on hacking that calibration as well.)

Idle can be wherever you want it - 1100 is good if you delete the idle bleed (which you should do since its such a hillbilly way to handle the idle on a DBW vehicle).
I've had it all the way down to 400 RPM, but that is just silly.
Phil's will be up and running Monday night.
Yeah, that would be pretty awesome. Save me the trouble.

Any sane person can come to the conclusion that "The Dude" and Lola know WTF they are doing and don't need to hack anyone's Johnny-Come-Lately tune to get an RX-8 running right (mine, and all the other flashed MT Pettit RX-8s have been running right since at least December). I don't think the accuser even believes it. I think he would like to believe it, but I don't think he does. I mean come on; he can't be THAT stupid. It totally makes him seem desperate IMO; like some cheap hooker trying to protect her street corner.
I also find it hilarious that "The Dude" and Pettit have been flash tuning RX-8s for the last 5 or 6 months, and he's arrogant enough to think that it's a big deal he created a Pettit-friendly tune "2 weeks ago." I hope Cobb soon realizes their mistake in associating with this monkey, and they soon puts a muzzle him. Monkeys are known for throwing feces, and that is never a good business practice.
BTW, Lola's quite the tinkerer, here's one of his hobbies:
He not only tunes these, but he builds them AND drives them. Much more close to rocket science (since this thing is a !@#$ing rocket) than a little PCM, which isn't as complex as a particular self-aggrandizing tool would like you to believe it is.
He was nice enough to let Juan and I climb into the seat (that's me in the picture). I was pretty surprised that I could fit in that thing (as was everyone else who witnessed it, I'm sure )

Nice! I always liked the open-wheel stuff. I'll have to settle for the Grand Am cars for now.
Eliminating the idle air bleed allows a much finer control over idle since the throttle isn't almost completely closed anymore.
The stability of the idle has more to do with the blower's proximity to the MAF than anything else. A proper MAF housing would go a long way to returning the MAF to its normal operating range.
When were they not that way? You are already in the 20% range at idle. There is plenty of torque authority on the part of the motor if you wanted to drive it at <2000 like you seem to fixated on doing.
