Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Everyone who had any sort of start stumble.
1. Post which tune version you used
2. Verify you are using the files that were just posted. Because they have the same file names as before.

 

91, 31 inch, stock gear.

dump tubes catted

 

Hmmm could be something with the 91 tune or dump tubes.

Just went and started the truck again. No hiccups or stumbles. Actually seems to start better than it ever has! (87 5.29 34-35)

 

91 octane, stock tire tune. Don't have many miles on it yet, but it is delayed start still each time.

 

Since Mat used the same file name, is it possible some users are actually flashing previous 2.0 final test file instead of one released today (May 17th)?

But from reading these posts so far, it's only 91 octane files. Trying to narrow it down and help clarify.

 

I’ve ran the Performance tunes from the beginning. Seems like 2.0 beta 19770 is the best for me. I enjoy driving it (and not having to press my shift knob ECT button). So if anybody ever uses their VFTuner to make a 2.0 final-performance tune for 04B04, count me in. All the base tunes (including the most recent) just seem “weak” to me.

 

04B04 91 oct. Today’s file, because I made a separate folders for the final iteration of the tune.

 

Great info. So we can rule out possibility of same file name user error.

 

Flash Manager is 1.3.0 but the P5flash is 1.3.1. Is this correct?

 

does anyone have the fix for the VCruntime140.dll missing bug??

 

@OVTune Start stumble is still there. Cold and Warm starts.

File downloaded: 04B04+2.0+Base+91+OL+31+-+33T.p5f
Verified latest downloaded file as I had deleted the previous one.

 

@OVTune any ETA on the rest of the P5F licenses for those who sent their dongle in? Know you are busy. Just wanted to make sure mine didn't fall through the cracks.

 

Quite odd because there are not many difference between the 87 and 91 files

 

There’s a dump tube file? I didn’t see one.

 

Good to know. But after I idiling 10mins can’t you just drive it to work out the kinks?

 

Do you hear your water pump more or is it me? Seems like certain parts of the engine are more pronounced or others are less than before

 

Hate to say it, but my truck did it once so far, but it is inside 100 miles. 30 miles so far and it is noticeably different how it drives.
HWY mpgs are awesome so far

 

Also under 100 miles (around 60) - cold start appears to be a bit better, but not where other tunes were. It wanted to cruise at 1,100 RPM... a lot - hopefully the 100 mile mark is where the magic starts to happen!

91 Octane & all stock 2016 Limited. Cleared AT & LV immediately after flashing.

 

87 base tune,

I uploaded the tune on a cold motor and it stumbled when cranking. Cleared LV an AT just after flashing and before cranking. still stumbling when a warm motor.

got engine up to temp and cleared LV and AT again, let idle for 15mins (coolant temp was over 195*F). stumbled the first fire after clearing the values but didn’t do it a second time afterwards...then I got busy and haven’t messed with it further.

Will let it cool overnight and see what happens in the morning.

Eta - just cranked it while warm and still stumbling.

 

For those with start stumble, might be worthwhile to flash the 87 octane equivalent file to compare.
