Any plans on a catless map for the s2? Does that even make much of a difference vs a high flow cat from a tuning standpoint?

Steve@VersaTune

Not much difference at near stock power levels. More tunes are on the way this summer.

Would Versatune be able to delete the TPMS and airbag lights for folks with aftermarket steering wheels and multiple sets of wheels?

I assume it can also handle a cat delete.

Steve@VersaTune

We can only mask ECU related codes. We do not access the other modules. TPMS and airbag are not managed by the ECU, so we can not mask TPMS or airbag codes.

Isn't there a Daikei Boss hub that can take care of the Airbag light for our cars?

I've learned to live with TPMS light.

Great! Do you plan on changing the radiator fan setting to come on at lower temps in future tunes? From what I understand that would be a great benefit to these cars, and is one of the main reasons I was planning on getting tuning software this summer.

You can do that yourself very easily. You can download VersaTuner prebuilt tune and edit the fan temp signals and then flash the new tune that has their tune and your temp settings. It's very easy to find the setting for that just by scrolling through their values and can be changed in 2 minutes or less. Flashing took me about 10 minutes from when I plugged into my obd2 til I unplugged

Is there a way you can show a list of available tunes on the program currently

Steve@VersaTune

The tune selection is limited at this time. We are working on expanding it. You can see the full specs and available tunes here: https://www.versatuner.com/features/mazda-rx-8-gen2

Steve,

just bought the series II package and I'm pretty excited. Can a rev match option be added? My heel toe shifts are usually trash Giant loaves of bread for feet. Im confident that this would make a great selling feature for your product I the future.

You sir ...are dreaming !

UnknownJinX

There was a thread a while ago that involves moving the aluminum cover on the gas pedal a bit to the left to improve heel-toe.

Cars with auto rev matching from the factory usually has a way to turn it on or off on the fly. It's not something I want to have all the time.

Banma

Well Disney princesses have taught me that it' ok to dream!

maybe I'm way over simplifying the process but hear me out: Both brake and clutch pedal have switches to signal that they are depressed. Could we just tell the ECU that when the clutch is depressed WHILE the brake pedal is applied at least 50%, apply .25 second of full throttle? If the 50% brake application is too specific(maybe the brake switc, is only an on/off switch) just make it so that the throttle function only happens when DSC is switched off.

The stock ECU can't be reprogrammed using reflash software ... you can only edit existing maps .

Dang

Although this is taken from Steve's introduction:

• Add custom functionality that is not available from the factory like launch control and no-lift-shift

RotaryR3

It does allow launch control and no lift shifting. But so far I haven't found a rev match feature.
it seems it could be possible though I doubt it would be easy.

Brettus

I do wonder how that was achieved given the constraints on the stock ECU and the hardware available . I suspect it doesn't work very well ?

Banma

I'll let you know in a week or two. Depends on how long it takes to get here.

RotaryR3

The launch control works fairly well though it doesn't hold the rpm the best. When I reached the launch rpm it cuts the fuel and it ends up dropping about 250-300rpm before picking back up again. Slow tach rate... So yes it works but could be better if they used an ignition cut and maintained the set rpm closer.

The no lift shifting can't be set to any choice rpm it is either on or not you choose at the time of flashing. If you put it on and use it then when you hit the clutch it will cut fuel til it reaches 8800 rpm the holds there and actually holds it right on it well. But this still is so high it results in over rev and a clutch dump. Would say it's only useful in a drag race situation where the lunge of power from dumping the clutch into the next gear can shave time off your run.

Steve@VersaTune

We use the stock rev limiter code which is fuel cut. It's possible that we may find the hysteresis value for the rev limiter which may allow you to tune the limiter for a smoother cut.

Custom code is totally possible with OBD-II flashing. We use custom code for LC / NLS.

I have looked into auto-blip, but have not found (if it even exists) in the ECU where it calculates the current gear. We can add the code to do it, but it's a major work effort considering the gazillion RX-8 ECU calibrations.

RotaryR3

Is there no way to use the stock rev limiter coding but switch out the value of killing fuel to killing spark instead to provide a more steady abrupt limit... It would provide a much more consistent launch instead of one time getting a slight tire spin and sooid launch then the next time getting wheel hop and little more than a rough ride.

Steve@VersaTune

I think the issue is more the hysteresis value and cut timer than fuel cut vs. spark.

Banma

Sorry, all I heard was, "we can add the code to do it" 😀

I stand corrected .
I have Mazdaedit and the rpm limit hysteresis is defined (200) on those maps so it can't be too hard to find.
There are maps to define the gears in there as well but I have never managed to figure out how they work.
