New VersaTuner performance tune

We published a new tune for Series II RX-8 today. It was developed on a 2010 RX-8 R3 with a K&N panel filter, high flow cat, and a catback exhaust. The before and after are from stock tune to the VersaTuner tune. The car was unchanged other than the tune.

Uncorrected Dyno Dynamics numbers. Real world numbers are probably higher. Also, pull done in 5th gear.

Pull was in 5th gear and only hit 120mph? I hit 118 in 4th on my 09 R3. And I dyno stock at 181whp to 192. (Depending on the dyno which the 181-183 range is most common results)

I think you should definitely be checking for issues be it compression, plugged injectors, or bad sparks... Something isn't right on your rx8

It's not my car and not my dyno. It was a remote tuning session. I'm not sure the dyno is calibrated correctly for the car.

+1

that seems really low, why didnt they do a 4th gear pull?

not really interesting in buying the performance tune if my engine looses more horsepower..

You understand that it's a before/after plot, right? The absolute numbers are less important than the relative numbers.

That about 10% increase then.

Could be a good baseline tune if I were to consider one in the future.

Are the coils the stock coils?

yes but having a shitty baseline doesn't seem like a great start.

I'm just gonna keep on keeping my S2 stock then because all of this is a waste of time.

I'm pretty sure they were stock as I didn't touch dwell.

Took a dive here guys. I bought the VersaTuner program with their cable they offer. Flashed in the tune they are speaking of in this thread and took the car out for a test.

On start up during the cold run cycle there was immediately a more noticeable "chuckle" when giving short throttle blips. After warming up there is 20 miles of parameter learning for the ECU of which you have to drive your car gently (harder than you know when the anticipation of the new tune is right there under the hood)

Now during the flash I chose to put in launch control, and no lift shifting. While both of these do work the launch control is a bit weak. When you hit the set rpm and it cuts the fuel it does it for too long causing a slow return on the rpm,. I'm talking 3700 set rpm and when it tachs it drops to 3100-3200 before climbing back up,. A full second to second and a half per taching. The no lift shifting is "OK" it holds rpm better but at too high of a setting approx 8800. Which means your still slamming gears and not anywhere near rev matching the shifts.

Alright now all the negatives are out of the way of which all I elected to flash myself and not part of the actual tune itself.

The tune itself is great for what you are paying for. I have all straight pipes so no exhaust restrictions, and new higher flow intake, which works well with this tune,. The valves openings are pushed back a touch rpm raised by 300, new AFR, dwells and oil injection is unchanged. This has yeilded a smoother power curve, much smoother! The power climbs clear up to 9100 or so by feel. And the overall power does feel increased but I wouldnt say much over 10whp but its is more responsive.!

All said and done I would definitely buy this again, and recommend to other owners. The tool allows you to do so much to and for your car. Data logging is built into the program as well with unlimited reflashes you can play and experiment at will( and at your own risk)

Why was the pull done in 5th isn't it 1:1 ratio for a dyno which would be 4th in an RX8

I wasn't running the dyno. I was remote tuning. I was focused on power increase between runs.

But in a 6MT, 5th gear is 1.00. 4th is 1.17 for an S2 6MT.

Any chance you'll be doing something like this for S1 cars?

So, I'm an RX8 noob. All my tuning experience was with Subarus and LS1 powered cars.

I don't expect much of a power gain in tuning the renesis but I would like to be able to take my laptop with me and tweek the car and try to get some cleaner afr's and maybe smooth out the power curve. How capable is this system? Compared to EFi live for instance?

How about compared to the old Turbo XS system that used to go in the WRX's? Cobb Accessport?

Screenshots?

Can it be expanded with an EGT or wideband?

The front O2 sensor is a wideband sensor. If you want to add more sensors, you'll need the hardware to do it. Versatuner just allows you to reprogram the factory PCM.

I realize that but have noticed in the past that the factory widebands are not able to read as quickly or accurately as some aftermarket units. In the past Ive upgraded the widebands and been able to integrate them into the factory system with a tuner, That's what I was hoping for here.

And if you are turbo the factory wide band range is not sufficient.
