Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Dang

 

Drove 250 miles over Mt Hood and back on 19700 4.88 (aggressive tip-in) tune yesterday and today. Power and great mpgs. Averaging 400 miles to a tank. Passing people is awesome with the gear/tune combo. Tip-in is fine for me

Still bouncing off the rev limiter at full throttle pulls from 1-2 or 2-3. Feels like it should be shifting at 5900, but rev limiter cuts fuel out at 6200ish. Otherwise, truck feels great. Ultimately, I'd like a gearlock + octane learning tune, but still be able to retain the ECT function.

Stock truck (besides 4:88's).

 

Both

 

Have you tried the 91 option?

 

Not at this time. Tank full of 87...

 

This is exactly my thoughts on the TC. Is it possible to limit the TC lockup to only 5th & 6th gears?

 

Just wondering what was changed or tweaked from the first beta 2.0 4.88, to this one?

 

He’s probably not gonna tell. He doesn’t want biased feedback

 

still no ECT? I want to go down to 87 to save some money but 87 with no ect kinda sucks.

 

I reflashed my 3.5 back to stock & sold it... will OVTune ever be available for a 2.7? Lol

 

Im on the new 4.88 tune with the aggressive tip-in and it’s great

 

Hoping for some help here as this has happened the last two beta drops and currently preventing me from installing 19800. Any thoughts from anyone as to what may be going on??

ZenDesk #10472 submitted yesterday and awaiting a response.

detail of issue as described in the ZenDesk ticket:

2017 Tacoma Pro Automatic with 04B04 ECU. Stock vehicle.
I attempted to install the latest 2.0 beta 19800 w/91 oct for 04B04. I’m a dongle user. When PCM Flash attempted to install 19800, it ended within seconds with “unsuccesssful” right after what I believe is hearing the fuel pump getting energized or some noise from under the truck. I tried again and same thing but this time I got a “brake override malfunction” error on my dash and a permanent CEL. I had this EXACT same problem with the previous beta build. From that ticket Matt had me do a Clear DCT, shut the truck off, verify no CEL, and then retire. At that time the retry was successful. So as instructed last time I did a Clear DTC, shut the truck off, verified no CEL, and then tried again. This resulted in the same unsuccessful message within seconds...though no brake override malfunction or CEL. Rather than trying again which I assume would likely trigger the brake override malfunction and CEL, I submitted the new ticket. Clearly there is something going on as I never had this issue prior to the last beta build and it continued with this one. Hoping you can help determine why for the last two beta build this issue is happening and at present preventing me from installing the latest beta.

 

where does one find the 16012 version?

 

16012 build was Octane learning correct? I can't remember because I always ran 93oct with it but I'm about to drop to 87 or 89.

 

Have you tried to flash any other OVTune you have besides 19800? What was the result?

 

If you missed downloading 16012 when it was up on the 2.0 public page it is not available unless it is released again.

 

latest betas are for non-dongle folk as they are p5f files. You need to wait for pcm files

 

I figured that was the case. Just received my kit a week ago. So I suppose I'll wait for 2.0 final!

So far this tune is doing wonders regardless!

 

Curious if anyone can give me some guidance. 2018 DCSB Tacoma OR, currently running on the 04A60 with 1.05 flashed. Im going to try and get the dealer to update to 04A61 so can utilize the 2.0 Beta tunes. (Too chicken to mess with TS after reading a couple horror stories)

Do I need to flash back to stock before I have the dealer do the TSB update so they dont have any issues doing the update?
