Anyone NOT Impressed with OVTune?

So with 87 and 91 tune you have to use 87 or 91 octane fuel? I just use regular 85 all the time and not really interested in buying premium gas.

 

It is a noticeable difference.

I tried have tried 87 base, 87 perforance and 93 performance.

I get almost similar mpgs on 87 performance and it drives/accelerates very close to 93 performance so I would go with that and save money on gas on each fillup.

 

You haven’t tried 91 base yet...?

 

That’s so mechanical items break in, and you get use to how everything is. It’s basically a placebo effect. When you get into a brand new vehicle it takes some time to get used to compared to the other vehicle you drove everyday. Also you get a little different feel as the engine, tranny, and rear end break in. Everything software related is staying the same. The algorithms and all the mapping. There is learning sequences in some vehicles when you do a replacement. I remember doing one on a focus. They had that big issue with the clutch recall. But after that learn procedure is done the vehicle is gonna shift and function the same 3 minutes afterward as it will 3 years later, unless of course the TCM was wiped. That’s pretty much how they all work

 

When you change the programming the values and mapping are going to be cleared. It wipes all that. Even if the idle is different then before the tune that has no effect while your driving. When your driving the tune will remap everything however there are still algorithms and theory the ECU must follow. What your seeing is the new mapping. When you hammer on the gas it doesn’t stop and think what it did the last time and it’s not going to deviate from any coding. It’s getting reading from the TPS, MAF, and calculating the timing and a bunch of other things and processing that to figure how much fuel is needed. Sure it’s a lot more complex than that but that basically the jist of it all. The techsteam is just allowing you to see the values and it maps out the progression so a technician or engineer can see the values/map. What you’re seeing isn’t much different that what a ford tech see’s with the IDS, Chrysler with the WItech, Honda with the HDS, or GM with the MDI or whatever their new scantool is called. I’ve used them all

 

It is not recommended to use lower octane fuel with a higher octane tune. There is no 85 octane tune, 87 (mid grade here in Colorado) is the lowest octane tune they have released.

 

Is it perfect? No. Does it make a difference that no other product currently offers on our trucks that is on the market? Absolutely. There's a huge improvement on driveability. If the truck currently doesn't bother you, I'd say stick with the stock form. I feel everyone who made the purchase probably did so because they hated the factory tune and learning of the vehicle. The minimal increase in power is negligible and really doesn't make the truck any more haul a$$ than before. At least to me it doesn't. But the everyday things such as power outpouring when hitting higher RPM, pedal sensitivity, and gear changes are all much more pleasant now.

Keep in mind, it is continuously getting better and not perfect. Thing's aren't as fast to come to market as other platforms. But what the crew has been able to do so far, and considering they're the only ones doing so, it's well worth the purchase.

 

They don't sell 91 oct in Ga and just didn't feel like it would be worth the extra $$ when 87 perf is so close to 93. My tip in adjusted and it drives great overall.

 

You can get close to the Hp gain just adding an intake. While you won’t get all the torque that you can from the OVtune some is better than nothing and you can get that for half the price. Would make a lot more sense for the Op since he is only running 85 and doesn’t want to run premium. Although I wouldn’t run 85 at all, I would atleast run 87

 

Which were the things I was interested in

 

100% worth it here too

 

I have tested stock intake, aftermarket intake, and no intake at all. None of them, in any combination, adds 15+whp.
Regarding the learning sequence, and "learning" in general.
You are correct that it doesn't learn and change any of the mapping. However the "learning" is that there are 16 + and 25 + Sets of tables for a given algorithm (lets use ignition for example) that the ECU will use to calculate the ignition degree. there are 4 primary, 2 mbt, and 16 4D comp 1, 16 4D comp 2, and a slew of other tables that all go into how the result is determined.

if the ecu uses "X" in RAM instead of "Y".. everything is compensated a certain way. The result is completely different than if "Y" was used.

Same with shifting tables.
Depending on what TCU value is set in the memory (RAM), you will never know what shift tables the code has called to load. So while it never truly "learns" new maps, it does shuffle between many of them. The end result is a drive that is always unpredictable.

 

You may want to try a tank of better gas.
Won’t help the shifting but the truck will perform better.
I’m not tuned but will pony up the money sooner or later.
My truck is at 13k miles I’ve switched back and forth between 87 and 93, there is a noticeable difference in the drivability on the higher octane. Much more consistent.
Sounds like you want to stick with 85.
Shift sense pro may be what your looking for and it’s a cheaper option.

 

To the op of this thread, I've been running OVTune about 6 months after it came out. Vast improvement and as the tunes come out, no charge upgrades, tweaks and dialing it in. Way too much list. Spent $500 on a performance carb some years back for another ride, this is cheap compared to all the tune encompasses. Like they say, if you're asking, probably not for you.

 

Hard shifts are not easy on the transmission or drive line. What your looking for is firm crisp shifts.
Slow slipping into gear will wear the clutch packs and heat the fluid up.
Hard shifts are hard on your universal joints, CV joints and various internal transmission parts. Really anything in the drive line.
I never seen soft shifts cause valve body issues.

 

You might have sold me here. Unless.. those OVTune dump pipes show some good results.

 

93 Performance = FTW!

 

You won't be dissapointed if you realize what the purpose of the tune is. Primarily, it addresses driveability issues that were inherent in the trucks from the factory. In my 2017 V6 MT, I've seen far better throttle response, increased low end response, a little more top end power and about 2-3 MPG increase. It's worth it to me.

 

I love that the OVTune exists, saving my duckies $$$!!!
I would trade one programmed tuned curve for a shuffling of tunes any day!

 

Op, if you have never used S5 or ect button then you probably dont need the tune. I have used S5 for almost 5 month that i owned the truck until I finally got the tune. Now I dont have to use S5 anymore. It was worth it because now it feels like a normal truck and not like a prius in eco mode.
