Major New Product Announcements: Pre-release info
You just make the full load ignition tables whatever you want them to be.
It will spray the NO2 because you are at full load, not the other way around.
I guess you will be running sub-optimal ignition timing when you run out of NO2, but that won't hurt anything other than performance.

^ I'm really liking this idea... Instead of trying to sync up an external nitrous control with the PCM, have everything controlled by the PCM directly... That would be sweet

It would be very easy to simply turn the VFAD output into a NO2 control and then assign it to the appropriate load level.
Think how cool that would be.
Just leave the NO2 armed and it'll start spraying when the engine is ready for it, based on what you tell the engine to do with your right foot.
You could assign the "VFAD" to open only at certain RPM, MAF readings, TPS, gears or anything else.

That is a good idea as well. Need to hack that bit of the calibration as well now...

I think you understand how potentially earth-moving a functional re-flasher will be to this community and, having seen your handiwork, I am convinced that you have the ability to make this happen.
I'd really like to see you beat Cobb to the market.

I'd like feedback from others, but I'm under the impression the proposed Cobb offering is a unit that allows the end user to put a pre-packaged "tune-up" (i.e. calibration) into their RX-8, with no means of tuning the said tune-up.
The topic of this thread is a product to allow the end user the ability to tune the tune-up.
Some say this is a worry. If you think about it in terms of a conventional carburettor and distributor setup, I'll just be proving a very sophisticated electronic screwdriver (to adjust the mixture) and spanner (to change the timing), albeit with a whole bunch of other sophisticated tools that can show precisely what is going on. Hopefully people will learn if they make mistakes. Hopefully it will empower a whole "generation", and perhaps one day people will feel just as comfortable tuning up their EFI as we used to in the old days with the basic tools on the carby and dizzy. Not to say they are easy! But is should be easier with all the monitoring and logging tools that are already in sCANalyser which we basically didn't have back then.
I won't be making anyone run their car in the wrong or dangerous state of tune. Just like I cant force anyone to drive dangerously.
I'll be providing a tool, intended to be put to good use, not bad.
And for those who are not worried having the ability to tune themselves (or want to perhaps spend less money) but still get a custom tuneup for their application, then I'm sure (hoping!) there will be a good choice of shops around who have this tool to provide a custom tune service for customers.

The Cobb will be (some day) tied to their Street Tuner software, that does what you are proposing.
It allows modification of virtually every parameter in the OE PCM.
This is what we want.
We want to second-guess Mazda.
There are plenty of ways to pop your motor. Please, please, please give us yet another. No pain, no gain.

Now that you have offered a new option, I will wait instead of going with Cobb. I have invested heavily in this club's vendors, and I'm sure you would like to hear, that I have the sCANalyser running currently on my laptop. To capture a larger customer base, are you going to offer pre-tuned maps? I plan on dyno tuning, but there will be those that don't have time or resources like me to get the custom tune, and that might persuade those on the fence to go down under.

Well I like cobb because
1) They have preset maps you can load up, no fuss no muss, no paying someone else to tune for you
2) IF the maps do not suit your needs, they will have a way via street tuner software to control *almost* every aspect of the ECU (to my knowledge)
Hymee:
I know you have the adjustment tools, how much adjustment do you have? If you also include base maps for basic stuff like NA boltons, high flow cat, no cat etc, and offer a better package for the same price (or lower) i'd be on board in supporting you.

so you say you can help us NA guys out????.....now im interested, would be great to see some results(dyno) and your price(lower than cobb)....no rush, maybe mid feb would be cool....

My plan is to support tuning shops.
But... how much is a "cheap alternative" for a in-shop flash tune? I know places like PowerTorque charge about $800 to $1000 for a reflash based dyno/tune-up for the LS1/LS2 boys.
But then if you get "service flashed" by the WDS at Mazda service, you need to go visit the tuner again for him to reflash with your custom tuneup (if he still has it on file)...
That means there is an alternative where you keep the reflash software/hardware so you can reflash your own car yourself, or take it back to stock if you like, without having to visit the tuner, but with no means of editing the flash.

Hymee.

in the end I'm not a good tuner and while the ability to play is a benefit I know my limitations.
The more i learn about this fancy efi/fi tuning, I believe i am coming to realize that it is actually easier to do than in the old days where you had some hand tools, a vacuum, gauge and a timing light--hell back then we were honing cylinders with a power drill!

how much is a good question. I would be spending about $500- 800 for a custom tune without hardware. the shop should only be charging a minimal charge for the flash and so the tuning is always going to be a cost that can't be reduced. flash tuners can't be tuned in real time so the tuning process may take longer.

The real bonus is that one good local tuner can tune many cars with one tuner device and spread the love. I haved tuned my race car using a tec3R (boinger) and being able to tune tune the stock ECU would be priceless.
