Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I try to identify in toyflash and it just crashes on me, any ideas?

 

Ignition on, engine off?

 

Correct

 

My interface box is also blank though. I'm using a tactix openport 2.0 rev e

 

Drivers installed?

 

For the cable? If it didnt come with the tune software then no

 

Yeah you need to load drivers. Instructions and link to download drivers in Ovtune instructions.

 

Oooof, now I feel silly

 

Glad I didn't have to pass you to tier 2.

 

Anyone in Sacramento 916 that can help a fellow TW out? I want to update to 0B04. I feel as Matt's taking he's sweat time so that everyone will update thier ECU.

 

"as if"

"Mat is"

"his"

"sweet"

 

“his”

 

Ok pretty sure when you clear DTCs for Engine/trans it also clear fuel trims and trans memory as clearing the Dtc clears freezeframe data as well as ‘monitor status and results’
But feel free to do it the other way. I did both ways.

 

Chipis, I am going to reflash the 87 performance tune today because it has been really temperamental. I haven't used the clear DTC function yet. Is there any harm in doing this?

I do this before I flash correct? Then flash, start truck, turn off truck, disconnect battery (10 mins), then 10 min idle correct?

 

So can we just use the p5flash utility to clear the DTC’s? or is that too easy?

 

It will work only as Mat programmed it to work. I believe Techstream has been programmed to do more...Im saying this based off my experience of using it, doesnt mean im right . Just do both methods via Techstream it will not hurt anything.

 

For us dongle guys without Techstream will this work the same?

 

No battery disconnecting as that doesnt do anything. Just flash your truck and then clear DTC for both engine and trans. Let us know if its still rough. If it is then clear fuel trims and trans memory via techstream the way everyone else has been doing it.

 

Im a dongle user. Mat has mentioned you cant reset/clear fuel trims via his software or unplugging the battery. You must use Techstream.

 

So flash first then clear DTC's on the P5-Can and the TCU?

I don't have Techstream and don't intend to install it because I'm on a work computer. Techstream has never been a requirement
