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?

 

+10 whp. see my thread "kane tunes my car"

 

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).
9) Should one decide to go F/I the AP will stay with you.

 

Question: Is the COBB AP for a stock RX-8 worth the $

Answer: Yes.

 

GET IT! you will not regret it!

Also, if you can follow instructions at a kindergarden level buy it from Mazdamaniac and he will do your tuning for FREE!

 

10) Read CEL's and clear them.
11) Flash Anti-Theft mode for when you leave your car at the airport for extended periods.

 

Thx, Kev. I overlooked those points.

 

What is Anti-Theft mode and what about increased fuel economy?

I like the increased rev limit (for autocross) and better mid range power!

 

The anti-theft tune is a stock map which sets the rev limiter to 200rpms. This, in effect, prevent the car from even starting. In theory someone could have your key but without the AP to flash back to stock they would be unable to start the vehicle.

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.

 

Cobb's Anti Theft mode PDF (Note, this is the for the '04 MT so check your year)

 

that's pretty neat, I'm sold.... thanks all

 

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.

 

The AP can keep them from stealing your car, not the cassette tapes inside.

 

You would have to be RETARDED to lock your ECU and then leave the COBB in your car for someone to steal.

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.

 

I can get the car fixed should someone really want to steal stuff. I'd rather they not try and take my car.

The COBB is portable enough to go with you anywhere.

 

ok then, you put your cobb in your bags....and the airline looses them. Cant drive your car until the airline discovers what state your bags ended up in....

 

Never check your bags

 

You mean it's not a magical force field? And to think that's what I bought the Club for.

 

I had my first experience with the AP this weekend, and I can tell you I'm frickin sold on it. Definitely a must have.

 

Cobb Sucks.
Period.
























Just kidding, it pwns!

 

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.

 

If you were to buy from MM, you would delete all of the tunes that are on the Cobb. (save them to the computer of course) You will download his basemap that is basically a stock tune with a raised limter, fans, omp work done generically. You follow his directions that are clearly stated in his tuning thread "Mazdamaniac Callibrations" about loading that map on your car, doing some datalogging, then emailing the base tune you used, plus the datalog files to MM. Its very simple. Then after awhile, he will send you a revised tune that is specific to your car. Then repeat the process again with your new tune about 2 more times. The only thing that sucks is waiting for the corrected tune when he gets backed up.

 

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!

 

This is why l bloody need one

 

Jeff will make any and all corrections to the MAF readings that will need to be done. But since you are using a stock intake and have no in/or out mods besides a drop in filter, maf work prolly wont be done. You usually only need to work on the MAF if you change out the intake or add a freer flowing exhaust.
