Note to Self-
Have EFIDude tools Check
Want AP with editing software (Edited, I can not have it as I have not auditioned to purchase it)
Add Want HymeeSoft Editor
Hymee, where do I send my check?

There will be behind the scenes people to thank, and all that will come out in the wash. For now, I'll keep tight and concentrate on doing what I know - developing quality software. I am blessed that I am able to mix my profession and technical abilities with my love of cars, and a passion to learn.
Hopefully it won't be too long before my product is part of this shootout!
Cheers,
Hymee.

I said this privately to Trey and now I will say it publicly. Anything Jeff says he knows about how a RX-8 PCM works came from Cobb. I doubt he did any of the Mazda reverse engineering himself. Jeff then tells the world how it is and how others are ignorant. Cobb stands by while he does this. You'll forgive me if I take offense.
Christian, Jeff is a professional that represents your product. He routinely uses gorilla marketing tactics to sell your product and you stay silent. I call him on the carpet once and all the sudden Cobb has something to say about childish behavior. That is a mighty high horse you are on pilgrim.
With the above said. I would like to contribute what I can to the education of the public. Here is a link to a FREE EFI 101 class, compliments of Cobb Tuning. I hope this demonstrates that I am not on any sort of high horse
I will be happy to field any questions as to how this information is pertinent to a rotary engine, essentially all engines are just air pumps and you do not need to own a piston engine to understand the principles of EFI calibrations.Take care,
Christian.

Thank You! I whole heartedly agree and will do the same.

Christian,
Speaking of helping, I tried to talk about the "difference" file approach and fear I've made a pig's ear of it. Could you please chime in?

Changes in flow distribution from a catalytic converter is documented in the information TeamRX8 posted awhile back on the FIA race cats. It shows how distributions change in the cylinder filing and if thats changing then everything upstream is changing as well.

Lastly, neither has file editing right now so there is nothing to compare. The Cobb is supposed to ship a file editing capability for an extra charge. EFIDude is supposed to offer a freeware editor downloadable from their web site. I suspect the Cobb software will be much nicer but have nothing to base that on.
Hymee, please do not tell me I have to audition for your product or otherwise have to provide a resume.
I'll edit my Note To Self to remove the Cobb AP from my wish list.

Feel free to cull through the threads and piece together a non-contextual argument to support that idea.
I have consistently said the same thing and I will say it again here:
The OE wideband does not read low enough to be 100% useful in tuning a boosted rotary application.
If you want to apply the word "accurate" to that, feel free.
The OE wideband also does not scale lambda output evenly at its extremes, but since it isn't useful there anyway, the accuracy of its scaling is not important.
The OE wideband is not useful for tuning a boosted application.
If useful = accurate in your vernacular, then I think we have other problems looming in the dialog.
Christian,

If you ever have time, you can sift through the hundreds of hours of logs I've made of injector timing, ignition timing, airflow meter output and a myriad of other data points under every possible load condition.
Then again, you would just steal the data, anyway.
Since day one on this forum, your entire MO has been to establish your position in this market and to steal as much proprietary information as you possibly can. Talk about "gorilla". You want to be the 800-pounder and all you end up as is the elephant.
Your "open source" tuning thread is just a preposterous phishing scheme.
BTW - on the "Stage 1" tune, I've pulled almost no fuel at all. This is why most people are still in the high 11's at WOT.
That tuning level only addresses drivability tweaks. The problem is dealing with various MAF tubing and its affect on fuel trim which is based on the ranges in closed-loop where I have trimmed fuel to reduce cruise load-up.
Nice try at asking politely to steal, though.
I like that. I guess that would have been an accurate assessment on Lola's part if he had an actual idea of what he was talking about.
I doubt that definition is what he had in mind when he said "gorilla".
OK. Now its starting to get old.

Power!!
It reminds me of an episode of "Setup." 10 minutes of actual racing footage in between contrived situations meant to artificially create drama. That's the car show I mean.

I see the first (on the forum) sale of a used Cobb programmer - there was talk of the unit being 'mated' to the ECU, to prevent one tuner programming all the RX-8s in town.....
Do any of you know if this feature made it to the final version?

The seller needs to plug the accessport to the car, and hit the uninstall screen. That will restore the car to factory settings, and allow it to be used by the new owner. Without uninstalling, the AP cannot be used on any other car.

WOW, I may have mistaken you as a professional. This sort of behavior is unmistakably childish. I hope I am mistaken and we can all continue these conversations as professionals. Otherwise, this will turn into another pissing contest that will do nothing but entertain a few.
Take care,
Christian.

Lola your remarks there are completely out of line. No more of that from you will be tolerated by me.
2nd if this Cobb customer is a customer of Jeff's why isnt he working with Jeff on dialing in his tune like others are doing? Is this car absolutely 100% stock?
On the other hand Jeff- I have seen this now from a handful of Cobb users with your maps. Have you figured out yet why we may see these lean AFs on a select few cars?

Come up with a comprehensive plan for addressing it? Sorta.
The problem is that there are variables that I have to address incrementally.
What I think I underestimated was the impatience of the people that have bought the thing.
I've got 40+ of the APs floating around out there.
7 or so are "problem" cars. Of those 7, more than one of the owners seemingly refuse to contribute useful data.
One way or another, I will address the issues, but I need some cooperation.
I'll attempt to draft a procedure that is more "user-friendly" so that I can bring those problem cars under the wing, so to speak.

I sprinkled it with my magical fairy dust (That was for Christian)!
It was just MAF calibration. the Maf curve is very long and very smooth.
The trick is to tilt it one way or the other until it balances correctly.
Then, the way it adjusts CalcLOAD will follow suit.
