Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Fyi, on stock B04 ecu, there is no "stutter".
1.05 induced it and made into the issue.
Stock B04 is handling the TC shudder very well. Once the truck is getting closer to the shudder region, it flawlessly shifts or unlocks TC. 1.05 is not shifting due to holding the gear and some dead pedal issues and that was painful to ride.
2.0 went around this issue by keeping TC unlocked. Better watch your tranny temps.

 

Mines 2019 04b31. Truck shaking doesn’t seem good and doesn’t feel good. It would only happen from 4-5-6 and primarily 5/6 since I rarely stayed in 4th long. The stutter happened from day one when I purchased in June. I’m not sure what exactly everyone else is referring to but trading in a 2015 for this 2019 I instantly felt the issue and was unmistakable. 1100-1300 rpm seemed to be the sweet spot for that issue.

As for trans temps, I don’t foresee an issue. If guys can do it in 4lo and not brake out in the desert and I’ve had no mechanical issues arise from the transmission in any Tacoma. If ever an issue were to arise I’d believe I’ll have issues when hauling wayyyyyyyy too much weight as I’ve done numerous times for 850 miles one direction at 70+.

Trans temps is something I’ll never watch unless there’s some very specific reason it’s needed. Daily driving I don’t see it ever being needed and if so I have a nice brand new truck with a lifetime power train warranty that covers it at zero cost with all the documentation to back it.

 

No hard proof, but I suspected my tranny temps might have been a little higher tuned. Either way, I just reverted to stock programming to give me a baseline for assessing 2.0 final once it comes out. I've been "tuned" for about 9 months now, running the most recently beta since it came out, and it would be nice to compare the final product to stock tuning. I burn 87 octane so haven't really tried any of the performance tunes - I just want a smooth ride with predictable power.

 

If the final 2.0 dosen't make me happier with the performance and driveability of my truck, I think a 2020 trd camry will be in my near future.

 

I stare at a Red TRD Camry outside of my dealers parts department. SEXY AF!!!

 

I noticed tranny temps went up by~10° on average daily commute. Probably not a big deal, but that's the derivative of TC tuning.
I'm about 2k on stock after all 2.0 versions and honestly I would fix just a few minor issue on stock and call it a day - adjust throttle limits per gear and handling throttle request, high octane usage( want to try 1.04r). So far shifting is smooth, no misfires, no falling flat after shifting to 3rd and 4th,no tc shudder, better fuel economy..
Will see what final version will bring.

 

What would happen if someone put a higher octane fuel in the 87 tune? Sorry if it’s been covered but there are so many pages on here it’s hard to find.

 

Nothing

 

Nothing...*bad*

 

You would pay more for fuel. That's about the only bad thing that could happen.

 

I’ve read the 2.0 info on ovtune but 99% sounds like Chinese to me. Can anyone sum up what 2.0 changes like I’m a 6 year old?

 

Tune good. Truck run better.

 

Truck go vrooommm!

 

Sum ting wong?

 

Wi to lo
