OVT tune group buy

[Tbot101]

A real test would be before/after 1/4 mile runs at local track. If it really gains 30hp, timeslip should drop three tenths of a second. Of course, the rest of the car would have to remain stock, no removal of spare tire or seats, no other mods to engine, full tank of gas, and stock tires.

Run at least three runs before, and repeat after "tune".

Reason I'm doubtful is back in the day there were "tune" chips for Camaros, Mustangs, and many others. Historically, they all cheated on advertised gains. Its been that way for 25 years.

I am not here to cheat anyone, but I fully understand the concern. Exactly why every single dyno sheet I own is 3rd party. People don't trust tuners, it's quite common.

I believe within that 100+ page thread on mazda6forums there was a guy who did track 1/4 runs to test that and took an entire second off his time (if I remember right). The slips are posted in that thread.

Not likely he dropped an entire second. The rule of thumb is 10hp=.1second=OneCarLength=100pounds. You can gain .1second by removing 100 pounds or adding 10hp. Gaining .1second is about one car length in 1/4 mile. If he dropped an entire second, his mods would have to add 100hp.

Right, I double checked and he dropped time by a half second. sorry

Here is his posts about his runs. 15.5xx to 14.9x
Car and Driver tests showed the 1/4 run from them to be right around 15.6

I read part of thread. He is power braking, which surely isn't used in magazine tests. Someone asked if he emptied the car of spare/tools, but he did not reply. There isn't enough info to say what gains are. Someone needs to take a stock CX-5 with a full tank of gas to the track and do back to back comparisons with and without the "tune".

Well unfortunately I don't think it will be possible to satisfy you guys if you deny dyno sheets and deny a half second off quart mile times.

Literally I have 10+ 3rd party dyno sheets showing gains yet I still get questioned like it's snake oil.

I've seen all sorts of things listed in magazines. They do ALL they can to achieve the BEST 1/4 mile and 0-60 times. Slip the clutch from redline? Seen it in the notes. Powerbraking, seen that several times in the test notes. "Neutral drops", no. That's outside the realm of what is sensible, but other than that...

Here's the thing, the fact that I can get those numbers from just an ECU tune is fantastic. Looking at all the dynos, its at least a 10% gain all across the board, almost too good to be true. Regarding the "3rd party" dynos, look anyone can just create a user name and post up a picture of a dynochart. And the fact there was a user name created just to contest this thread throws all kinds of red flags. I want to believe in the OVT tune for the SkyActiv, but I can't only rely on claims from a forum. I would buy this and test it myself but going out and getting my car dyno tested takes time and a lot of money which I don't have.

Remember the intake tornado?

http://www.tornadoair.com/

Yeah with all that fancy jargon that was almost believable, too. This reminds me of that. It would be nice if an unbiased 3rd party with access to their own testing equipment test it out and post the results. Kinda like back in the old days with Sport Compact Car. If OVT is serious and willing to back up there claims, submit a tune to one of the car mags and publish it. I remember when Hondata was just a nobody. Look at them now, a very well known reliable ECU tuner.

 

[Chris_Top_Her]

I wouldn't call it a red flag, if you search the old username "OVT" it no longer shows up. So for whatever reason it was removed. Thing is multiple times in the links provided those dynos and data are from a 3rd party; namely other users. OVT is already known as a reliable tuner withim the community, producimg real results (including turbo sky 2.0).

Will this suffice? http://www.tomshardware.com/reviews/mazda5-technology-upgrade,3966-8.html

How about this?? http://www.good-win-racing.com/Mazda-Performance-Part/61-1790.html

You guys truly think GoodWin Racing would have anything to do with us if we weren't legitimate in our claims? Call them and tell them their dyno sheet is fake, done on THEIR dyno!

The fact that I must go to such lengths to prove what I have done, not to mention the worlds FIRST Turbo Skyactiv tuned.....
How about this? Skyactiv 2.0L running 8psi of boost on my tune. Surely that isn't something you can fake. Good Luck faking a full throttle boost pull on these engines without blowing them up.

It is really unfortunate but reasons exactly like this is why so little development gets done in the realm of modifications for these cars. Think of the BRZ. same idea, direct injection N/A high compression. They have superchargers, turbo kits, EcuTek RaceRom with custom maps. Part of the reason is because they don't chase away the only companies working on such things.

I sure doubt EcuTek would list us as a Miata Master tuner if we were going around selling snake oil..

anyways, that's all. Group buy is closed. sorry for anyone who was truly interested.

Or www.ecutek.com look us up, Mazda Miata Skyactiv Master tuner.

The first link is for a Mazda5 with baseline test and no ECU tuning was done.

The second link leads to Goodwin' Racing website. Goodwin Racing's goal is to sell stuff. Hard to confirm there isn't some bias ...

I used to work for a tuning garage, I know it takes a lot of time and effort and I applaud you, especially for being one of the few to turbocharge a N/A SkyActiv engine. That's ballsy and if you can pull it off demands lots of respect.

 

[tibimakai]

I'm a novice, when it comes to ECU flashing.
How this can be done, if I'm not local to you?
Definitely would help, to post all this gains/videos/graphs on the OVT site. All I see is a Mazda engine there.

 

[Tbot101]

Can you tune it without bumping the redline? My concern is more for the transmission than anything. I have never had an automatic that didn't have issues, and I know rpm and shifting and shift points do cause issues with some. I'd just be happier without the bump, is what I'm g3tting at. Hp loss near 7k rpm isn't a concern to me.

Of course, rev limit bump isn't required, we have our general safe tested limits for each, but we allow the customer to decide what they want if they want something specific (unless it is outside the bounds of what we have safely tested).
We have safely tested:
7600 RPM 2.0L
6800 RPM 2.5L.

I'd be happy just leaving it stock rpm.
Does the valve timing get tweaked? My only other concern was carbon deposit increase. I am led to think mazda tuned the valve timing specifically to avoid it. Is that maintained?

Also, all. Legit tunes exist for the vq37 in the 370z. Mazda hasn't even had a thought as complex as the ECU parameters of that engine. I'm sure that sky active tuning is cake comparatively.

What are those gains worth, 0-60 and is it readily felt when passing? Is there a way to switch between 87 and 91 tunes?

absolutely, we adjust and calibrate VVT as well, consisting of over 10 different maps in the ECU for various things like load / speed / engine rpm / valve timing for efficiency and MPG.

I wouldn't compare the 370z ECU complexity to the complexity of the Skyactiv, but I would say the skyactiv is a *bit* more complex, as it has multiple modes based on engine speed and vehicle speed, Many different phases of injection, very complex cam timing that serves many functions, and multiple different ignition strategies. Not to mention the torque control and Multi tier knock control.. It's very complex.

Interesting. More complex than each valve having its own motor and infinitely variable lift? Damn...

Do you guys have pinpointed hiw mazda keeps the carbon buildup down via timing and have you maintained that?

Definitely not that complex of a VVT system. The exhaust cam is oil controlled, intake cam electronically controlled. I guess it wouldn't be fair to say it's more complex. I better way would be more complex in some aspects, less in others. Goes for both.

Yes mazda designed the engine to keep the intake valves as hot as safely possible to help burn off build up. It works, but build up still happens. The vvt maps are altered to help with it, but it doesn't completely stop the build up over time.

I plan on doing a boroscope inspection to see how much gets caked on. Maybe at around 15k.

 

[MikeM.]

I would expect your valves to be really clean at 15K. Remember, the CX-5 has been selling for over 4 years and there are a lot of examples with 60-120K miles on them. I haven't heard of one issue with carbon deposits on the valves which is telling, particularly since we know a number of those cars have been used in the frigid winters of the Northern Plains, Canadian Arctic, Russia etc, places where you might expect to see carbon/valve deposits, especially in those vehicles used for a lot of short trips. Yet I haven't heard of a single case. It looks like Mazda did their homework when they tuned these engines.

Time will tell how engines with aftermarket tunes fare over time. But don't expect to find anything significant on your engine running Mazda software (especially with only 15K miles).

 

[davesxx01]

OK, regarding valve deposits.

Mazda has a dual injection per cylinder cycle to somewhat help with keeping the intake valve hot (+400*) and that helps somewhat.
I have owned 2 VW's ('10 GTI & '13 Golf R) that were/are prone to valve deposits that required cleaning at 60K. (pull off intake manifold and walnut chip blast) VW has somewhat cured this with European cars by adding a second injector in the intake manifold. Sadly, it wasn't approved for US use.

As all manufacturers have gone to Direct Injection lately it will be interesting to see how each combats the issue of valve deposits.

Although I am in the beginning process of tuning my case will be interesting. I live in Wisconsin and drive less than 3 miles to work every day,,,,, meaning my valves will get caked fast.
Some in the VW circles use EGR block off plates and PCV catch cans to keep oil out of the intake. I may have to look into something like this myself.

VW has told their dealers to hold RPM's at 3K for 10 minutes to help burn off deposits. Folks like me may have to go for a extended drive at higher RPM's every now and then to help with this.

If Mat or anybody that's a Mazda tech cares to address this it would be great!

(Myself? I've been a Ford Master tech for over 15 years, but that was over 10 years ago,,,, well before Ford got into DI, and am over 50 yr old but young at heart!!)

Just like with this tune, only way to find out is to test it.
