Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Seems correct to me.

 

Careful... you might trigger someone

 

No Performance updates to 0B402 or 0B403 DAM! Well i am going to have to find a dealer who will TSB my shit so i can get some Performance tunes.

 

Scratch that dealer stuff . I am just going to flash back to 1.03 its the only tune so far to work well with my trucks setup.

 

Or just TSB your own shit

 

Oops! I forgot to clear the values after flashing and went for a drive already after idling. Can I still clear values and continue or just restart and flash again and then clear values with TS? Thanks in advance.

 

Mat actually said to clear only if you experience issues. Just run it

 

@OVTune matt can u tell me, is the performance 87 tune different in other aspects other than just tip in?

 

Different than what, compared to?

 

The 87 base tune

 

Changes include:
Throttle Air calculation limiters (atmospheric weight..probably not the most ideal way to describe) 4D control
Throttle Airload Limits
Throttle RN6 - Calibration (Reverse, Nuetral, 1-6th)
Shift tables have been slightly adjusted (but still close to base)
and some other things.
93 octane version has other enhancements like fueling / ignition etc

 

My truck is very tempremental in lower rpms. It ran perfect on 91 base tune. On the 87 base tune it bucks or stumbles in low rpms when you try to give it gas. It did it on factory tune and tsb also. I was wondering if I should just go back to 91 base or if there was enough of a difference in the 87 performance if I should try it first.

 

Submit a ticket with full truck information :ECU ID, octane / tune files that have issue, Truck mods, etc

 

Ok thanks maybe I'll give it a shot first. I should have just left it on 91 base. But no 91 around here and 93 is over 3 bucks a gallon. Can u recommend a octane booster that u have found that will give me the 4 needed octane points that isn't 20 a quart

 

I figured I would submit a ticket once u get all caught up. I don't want to be one of those people bothering you when you have tons of shit to do. Lol

 

Maybe the issue is that since you've flashed the 91 originally, then 87, if you did not clear the ECU learn values it's using 91 learned KCSV and it's going to have a lot of knock retard and run terribly.

 

I reset all learning values with techstream.

 

Okay then submit a ticket with all the info I requested please. I will get to it as quickly as possible.

 

I see, I just clear it for peace of mind since Mat has said on some trucks the flash does not clear the learned values and it seems to me using TS to clear is better than pulling the battery, I figured it would do no harm. Thanks I will just run it as is and once I try out the performance tune I will clear after flashing next time.
