I ported this tune over from S1 since it's for a pretty common hardware setup.
We built it with 91 octane and a REVi Intake and TurboXS catless exhaust.
This is the dyno chart:
so going back to stock APV opening RPM made more power for you?
Got rid of a big dip/surge with a corresponding smoother load line and virtual dyno. I'd have to get on an actual dyno to see if the later APV opening is better but I can't really see how it would be.
Well I’m gonna be hitting the dyno in the next month or two. Still lots of snow here.
Anyway. I’m gonna be spending some time trying some e blends. Not looking for power gains but say we add 5 gallons of e85 to a tank topped with 93. If the fuel system allows for the extra fuel load it should reduce engine temps by a decent amount. It is very common in ecoboost stuff now. When it’s cold like this week and I’m running e30 it’s very noticeable in the temp of the car running. If that was to translate over it would be a very good addition to helping our heat problems on hot days.
at the very least it if we keep everything equal it should be a nice safe guard against knock with the added oct. especially on very hot track days at high rpm.
my main goal is to adjust tune and account for CAI and open exhaust (catless midpipe) to get some more power up top( 5k to redline) as the car is mainly track toy. I am not sure if mazdaedit or versatuner is the way to go for S2 and there is very few people tuning their S2.

Well I offered up my car to Steve at versa tune to play with. He said he could have it done in a day but I am offering it up for a week or two. Just a spare car.
So hopefully he finds some magic in it. I’m looking for the same thing you are just a bit more and some longevity. Back off oil pump and premix a bit more amsoil and make the fans kick on earlier to keep it cool. And of course more rpm up top.
Not gonna lie not even gonna be sad if I pop it as I really want a ported one.
I would be very interested to see what you were able to achieve with your set up and tune. Just make sure he does stock baseline and then final tune so we can see the difference.
I also want to block some engine check lights (cat, airpump delete, etc) /fan on temps and similar things to what you were mentioning.
For sure a dyno doesn’t do any good without a baseline. Could care less what go it reads just what it gains. I have run into cars with way higher dyno sheets that are simply slower but baseline and top numbers where higher but gains were not.

If I may interject. My stock block s2 with FBO is tuned via MazdaEdit by a highly regarded forum member. Using the Edit program came as a recommendation from my tech (very experienced Mazda racer, based on many factors) and so I sold my brand new unused full VT at a substantially reduced price. If its meaningful for you, I'd either recommend finding a reputable shop who's familiar with the Edit program and they can make the proper adjustments for you or reaching out to some members here to see who can or is willing to help you.
My car is relatively new to me, never dyno'd, etc. Custom tune on n/a Renesis isn't going to be very noticeable performance-wise imo, maybe scavenges a few hp's from the band. I'd say it primarily helped with throttle response and further smoothing of the powerband. You shouldn't have too high of expectations, it won't be anything like gains a custom tune for a turbo vehicle will get you.
I understand it not gonna give me huge gains but being able to control the things to make it live longer is a bonus. As for tuning if you have never been on a dyno you are missing out. As someone who has been through the process many times you are never gonna match a true dyno tune with one from data logs and email. Even the top E tuners admit that much.
I except maybe 10 go at most with cooler temps and a higher rpm. Reduce oil pump because I run synthetic and supplement with more premix.
I’m not sure a Mazda edit is gonna get me anything a versa tune won’t.
If you were more specific I’d be willing to here you out. I know why the Livernois tuner is better for the big 3 cars and can tell you why it’s better than Cobb and others.
Steve, I have an S2 2010 R3 manual with very small porting and Racing Beat header. Which tune should I use to take advantage of that and 92 Octane? I have a pure 92 Octane pump in the area.
I'm thinking of getting the Tuner Lite and Versa Link cable for most reliable logging and programming. Racing Beat header causes Air Injection Pump Flow Incorrect code 4011 to pop up due to O2 sensor placement not seeing the first exhaust runner's flow as much as OE.
I should be able to disable that code easily on my own, right?
Hi @Soravia
I own a full version of Versatuner for my boosted RX8.
I can’t say which of the “off the shelf” tunes would work best for you, I have my guesses …
But I can answer yes you will be able to mask the check engine light with the VT Lite version.
I would also say you don’t really need that expensive Versa Link cable for what you are doing.
It’s a bit overkill but hey whatever floats your boat.
Im using the OBX cable with no issues and considering getting the Bluetooth
EDIT: Mistake I’m using the ODBLink SX cable
oh one more thing, have you tried the VT forums? Likely will get a quicker response there from Steve.

There are only two options that are close to what you have:
6-port: 91US/95EU Octane Stage 1 RX-8 with REVi Intake and TurboXS catless exhaust
RX-8 High Flow Cat and Catback 92 Octane
The first of those is probably closer, but neither will likely be an exact fit. You will be flowing a bit more with the header and porting. Your ideal APV and VDI opening rpm will be different.
As far as the cable goes, 99% of people only need the $40 OBDLink SX. If you're not planning to use other software that requires J2534 DLL support, you don't need the VersaLink.
I made a mistake I’m using the ODBLink SX cable. I’ve corrected my post above.

Avoid ebay clones of name brand cables. They tend fo fail prematurely and/or have incomplete firmware which will brick your ECU or fail to complete when you flash it.
