2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

@RaunchBox - I too have had a similar issue. I didn’t consider it being related to the tune, but after reading this I’m second guessing it. I am on 1.05B 87 tune. Was driving normally and as I was rolling down the road the auto LSD light came on and stayed on. A moment later the traction off light came on. I toggled the traction button and the lights went away and haven’t come back. @OVTune is it possible that the tune could cause this?

 

What the hell??

 

I feel your pain lol. Mine got progressively worse, everything began faulting out. ABS, Traction, CRAWL NOT AVAILABLE hah I'm not supposed to have that sir! Everything was flashing and beeping and going crazy.

 

I'm not even sure how it could...nothing out of the ordinary has been modified vs any other version..

Are you getting a Check engine code? If so can you use our software, "read DTC" and tell me what it is


Did this happen while trying to drive while the engine was still cold?

 

No check engine code but I can read it out anyway to check. Engine was cold, happened on my way home from work after sitting 4 hrs. This has never happened before. This was a week or so after initial flash of 1.05B. Day 1 of the flash I gave the truck hell but have been driving normal since.

 

^ same

 

I highly doubt the tune is causing these fault codes/lights. If I am not mistaken the tune only makes modifications to engine controls, timing,fuel trim,valve timing ect. I don't believe the tune modifies the traction control/abs system in any way that could affect those.

 

The wait for '19 support is a real life struggle

 

Very much this....

 

Sorry '19 guys... very soon though. If I were a betting man, I'd say it's gonna come with the new FM.

Buckle up!

 

Finally got a chance to flash to the 93 tune. I'll be taking the truck to work tomorrow to see how it goes.

 

What’s typically the best way to get ahold of Mat? PM on here or email? I bought that used dongle Tuesday last week and the last email I have from him is mid day Wednesday

He’ll get back to you. This week he’s been working on wrapping up flash manager, updating the tune and adding some new stuff.

 

@OVTune , is that "single map for all gears" file going to be ready and available for all when the new FM drops?

 

Yeah I understand. I’m trying to not be impatient but it’s hard. I’m like a kid who has his Christmas present in hand but without batteries right now.

 

Oh for sure - we’ve all been there. He was doing some dyno work this week so is a bit delayed on tickets than normal.

Registration is typically the longest part of the process. Flash manger is going to make new releases MUCH better

 

I've been following and reading this thread for awhile. Now considering going with it at 1.05. My question is how many have gone from the tsb to 1.05 and feel it was a significant upgrade?

 

@02Duck
I have had the tune since the first one offered for the M/T and I have always run the 91 files. I did the TSB and it was an improvement over stock but the tune prior (1.04) was still better IMHO than the TSB. The post TSB versions 1.04r/1.05A for the M/T improved upon the prior releases and TSB and incorporated some of the TSB changes IIRC. Most of the M/T guys have still not had the opportunity to try the tune revision that includes the table expansion that followed the initial release of 1.05 for the M/T.

The upcoming release with the expanded tables and with the added options of performance/economy tunes,single table shift,full otto,throttle by gear control tables,throttle torque by gear control tables,throttle limit control ect. should be a very significant improvement over the TSB.

 

Same. It gets better with each iteration and is exponentially better than stock.

I’ve been tuned for over a year now. The TSB is a definite improvement but during that time I definitely noticed and missed the improvements I had with ovt

 

@M1Awolf, @Shellshock
Thanks for the feedback. The tsb helped alot but there are still spots that I'd like fixed. Sounds like the tune is the way to go.
