POLL: OVTune Reviews (3rd gen)

Took a couple hour drive today. 17 dbcb AT running 91 performance. At 83 mph rpm was around 3300 with cruise control set. . If I tapped the throttle would upshift drop to around 1900 for a few seconds and then back again. Without cruise have pretty good dead pedal in the middle and feels like it wants to downshift hard to keep up. Then over all again if speed drops. Any suggestions? Thanks

 

Are there any issues when going in for biannual smog checks? Is it detectable or do you have to put stock tune before you go in?

 

From everything I read it is not detectable and should pass normally

 

The first post of this thread or OVtune.com will answer your questions. It's been stated numerous times in this thread.

 

The issue is the double overdrive with bigger heavier tires and truck don't work well together even with the tune. 1900 RPM is just too low for that engine to make enough power to overcome the wind drag, gravity, weight, regardless of the tune. The tune helps but it can't work a miracle to pull that much drag at such a low RPM. Gears are what this truck needs. I did 4.88 and I have the 91 base tune and truck handled 80mph+ with 4 guys and camping gear so much easier. It would run between 5th and 6th most of the time. before gears it needed 4th way too much to try to maintain that kind of speed with a lift and heavier/taller tires.

 

Thanks for your response. I appreciate it. I just don’t remember it running like his before the tune? Pretty sure it did not sit at 3100. Maybe 2500? Can’t remember

 

If I were to buy the latest OVTUNE and if a new update or version were to come out, do you get those as well for free?

 

Yes

 

I’m sold. Getting it next paycheck

 

Does the $699 include tunes or is that a separate cost? Thanks

 

All current and future tunes are free.

 

Edit; Dang he quick ^^

Includes all the tunes, and future updates

 

Yes it includes the tune. Once purchased, all of the future updates and info are available for free

 

New release coming (with a new one and assumed exploding sales, wow)... full exhaust?!

 

Order number 4119. I've had mine since the sale that occured around tax time in February 2019. I loaded version 1.05 of the 87 gearlock program on to my 2017 TRDOR in March. At first it seemed awesome, I noticed that it didnt want to downshift immediately. I've had major gearhunting issues since I started adding weight to the truck, and really whenever I travel in the mountains. By the time I loaded the Tune, I had already re-geared to 4:88's, added a shell, dual battery, SSO slim line bumper, and sliders. The 3rd gen motor/trans is obviously the problem in my case, but I bought into the hype with the Tune. After being unsatisfied with 87 gearlock, I'm currently running 87 performance... It isnt much different in my opinion. I still cant pass going up a hill, and when traveling in the mountains it still cant find the right gear. Granted the throttle response has improved, but for me the biggest problem is its inability to stay in a gear. The downside of performance is when the truck wont shift and you continue to apply pressure to the pedal at a certain point it will spike the RPM's to 5500 and zip right toward redline before downshifting back to 2k RPM's. I spoke to Matt Wilson at OV and he offered me the opportunity to test tune version 2.0. Obviously I jumped at the chance, however when he sent over the file, he also included a disclaimer basically stating that it's still flawed and they are aware of the issues I might experience after I load it. Why would I knowingly load a flawed tune? it's already been a joke.. So at this point I've given up. I'm dismantling the truck and going back to a 2nd gen. Whatever happens with the 2020 models, i doubt the motor/trans combo toyota is proceeding with will ever be remembered fondly. Bummer. I put a ton of cash and effort into building a turd gen. Lesson learned.

 

The tune isn't "flawed" it's a beta, and 5th/6th gear was still being worked on which was explained. Which is already been adjusted in the updated version of 2.0 sent to people.

We gave you the file to get your feedback. Thanks.

With the extra weight and going through mountains, by limiting yourself to the 87 files you didn't gain any torque or power so I can understand why with the extra weight it was unsatisfactory, especially with extra weight.
There's a 50+ ft lb difference between 87 (stock ignition) and 91...

If you were expecting to hold 5th or 6th through mountains w/ extra weight on 87 tunes I don't think that will ever be possible and we apologize if you thought the tune was capable of this. If you factor in the change altitude with mountains it compounds the power loss.

 

The 2nd gen was a steaming pile of trash compared to the 1st gen... might as well take it all the way back.

 

One of my biggest gripes about the 1.05 tune is that it doesn't downshift by 1 gear, instead when i press the pedal harder and harder it does nothing then suddenly jumps two gears down and revs all the way up. All I can say is WTF??? I have started driving in S mode and shifting when I need to instead of relying on the shift tables, which suck ass. Heavy truck with 33" tires and 4.88 gears, 1.05 91 performance tune with over 5k miles after flashing, drives like shit.

 

I'd highly recommend you try our beta 2.0 for the 4.88s. The shift scheduling on 1.05 is for stock gears and stock tires..

Just so everyone is clear when reading.. the tune was developed on a stock truck.
If you have an extremely modified truck like : Lift, large heavy tires, different gears, additional weight, etc it's not going to be ideal. That's why we are working on different version for different truck setups.

 

I'm relieved to hear that. After reading OV's response to my feedback I thought I should try 91 before getting rid of the truck. Considering you're experiencing the same behavior, I feel ok about my initial response. I chose to avoid 91 because of fuel costs and availability in some of the more remote locations I travel to.
