Is the COBB AP for a stock RX-8 worth the $
I have a stock RX-8 with no plans to do any modding.
I drive the car daily (parked for the winter) and autocross at every opportunity.
What benefits, if any could I expect to see with a stock RX-8 and an AP map adjustment?

1) Increased OMP volumes for better internal lubrication.
2) Slightly leaner A/F ratios for a little more power.
3) Better throttle response, especially through the midrange RPMs.
4) Lowered radiator fan "turn-on" temperatures.
5) Raised rev-limiter.
6) Raised idle speed.
7) Data-logging.
8) Real-time display of a single data point (most people monitor the A/Fs).
9) Should one decide to go F/I the AP will stay with you.

In the hands of a capable tuner the Cobb AccessPort allows for several things, such as (but not limited to);
1) Increased OMP volumes for better internal lubrication.
2) Slightly leaner A/F ratios for a little more power.
3) Better throttle response, especially through the midrange RPMs.
4) Lowered radiator fan "turn-on" temperatures.
5) Raised rev-limiter.
6) Raised idle speed.
7) Data-logging.
8) Real-time display of a single data point (most people monitor the A/Fs).

11) Flash Anti-Theft mode for when you leave your car at the airport for extended periods.

Increased fuel economy would be a byproduct of leaner air/fuel mixtures. Cobb provides an economy tune but honestly I get better mileage from my MM tune which I use all the time.

I have a concern with the Anti theft mode.
Most wouldnt want to carry thier Cobb with them on a trip. So you load anti-theft map and leave it in the car somewhere. Thief breaks in..cant steal the car so he grabs anything he sees of value in the car instead. You come back to a broken in car that you cant drive and you cant unlock the ECU.

If you travel so light that the COBB won't fit in your carry-on or your checked bags maybe you should take a taxi to the airport.

Ok, I'm looking to buy a AP (From MM of course) and I'm curious what exactly you get with his adjusted calibration. I realize he is correcting for mods and condition specific to my motor but these adjustments are being applied to the 4 maps that come from Cobb and that is what I get back from him, 4 adjusted maps plus a "baseline" for another tuner to work from? Also, and what I'm most curious about since I'm unsure of any knowledgeable tuners in my area, does the MM adjustment include raising idle speed, fan on temps, basically what's mentioned above or is that something a 3rd party tuner must do? I'm not planning any drastic mods beyond a cat-back and BHR coil set, possibly a midpipe.

I see, that clears up a lot for me. I assume his tune is ment to replace that Cobb map and most keep their Cobb economy, valet and anti-theft maps for use, assuming they used them to begine with. Also, in the 2 or so revisions, his further adjustment is based mostly on datalogs or does the ole seat-of-the-pants dyno information factor into it?
Using the stock intake system with a K&N drop in and disconnecting the VFAD, would it be prudent to do the "scale your MAF" process stickied in the tuner forum or is that not needed with stock intake an/or something MM will have already corrected?
Thanks for the quick and helpful info!
