Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Is Mat still out of town?

 

This guy gets it!

 

I most certainly haven't gotten it!

 

It appears that I am one of the only ones that has a decent running stock truck. I have been following the ov threads for months anticipating buying 1.04. The problem is my truck has never hunted gears in nearly 20k miles. It is certainly not a race tune from the factory but it runs really well. I get great mpg in town and on the highway and, since I had the rev1 flash 18 months ago, there are no shift issues. I can count on 1 hand how many hills I climbed where it made it to over 3000 rpm without upshifting in 2.5 years. I will say that since rev1 I drove it like I stole it and I believe that helped the learning of the ecu. I will also admit that Atkinson belongs in a little car and not in a Tacoma. It has periods of sluggish performance but that is based on grandma driving. 90% of the time when I stomp it the thing takes off. One thing I avoided during the relearn was allowing it to find 5th or 6th gear under 40 mph. It only does that if I baby it up to speed. As long as I am somewhat aggressive the gears shift when I expect them to. I was planning on having the tune by now but I am going to give it another 6 months. I really would prefer waiting until I pass the stock warranty. Time will tell. The bottom line is that I got very lucky with my factory truck and am still a holdout for the tune.

 

I am back in town as of 2 days ago (not in VA yet). Will be sending out more files tonight.
Next step is dissecting Toyotas new TCU code. No ETA on how long it will take, likely a few days.

I appreciate the patience everyone. I hope to get through toyotas new update as fast as possible to implement this as a standard update in all tune files for 1.05.
Which means there likely will need to be a 2nd version of 1.05 with the new TCU (along with my new TCU developments) and setup for best efficiency. Have not yet decided the approach yet on that. But I figure it is better than sending out revised 1.04s..

Thanks Toyota. (I still love this truck)

I have talked with Magnuson is what I meant

 

So um, any more thoughts on a M/T dev truck?

Asking for a friend.

 

Tell those sob’s socal exotics wants to know when they are supercharging his third gen tacoma XD

 

Mine was pretty tolerable on the stock tire size, but when I lifted and went to 285/75s it quickly started to annoy me. It almost feels like it is pre rev1 and I hope the ovtune makes it more enjoyable again.

 

Hmmmmm..... a Wednesday morning truck perhaps?

 

@OVTune, since you are going to be dissecting the new TCU code for a bit, is it okay for me to flash my truck back to 1.04 yet or do I need to wait?

 

Not on "reading the very first post" level??

 

I just want any tune on my truck, almost all of the reviews are outstanding for all the recent versions! Here's to patients!

 

Mods are sleeping.

 

HAHAHAHA!
Dude. You live on the edge. I hope no one reports this cause I’ll get the blame again. lol

 

Savage!

 

SUBBED!

Looking to buy a 2019 Tacoma SR5 DCSB 4X4 by this time next year. There are still a few 2015 4.0' 4x4s available for around $30,000 with approximately 15,000 to 20,000 miles on them, just in case I go that route. I drove a customers 2017 3.5 last week & I have to say that my '08 4.0 Prerunner drove better (referring to trans shifting) & my 4.0 "feels" a bit torqueir but I'd like to buy NEW so I'll be checking this thread & what ever TSB update Toyota comes up with by then as well. I've read that the 2018's have an overall better factory tune the the 2016's. I like the look of the 3rd gen, I don't care about MPG's, I don't care about any tech stuff, but I would like for it to drive & "feel" AT LEAST as good as my 4.0. I have absolutely no issues with my Prerunner but I want 4x4 & new, or at least newer than my '08.

From what I've read so far @OVTune "Matt" is the man!

 

You can't go back. Your ecu and tcu are both new.


New ECU ID 04B04 (updated from 04B03)


I will let you know when it's ready. After 04B04 is fully supported I will port all of toyotas code updates into older ones (04B02,04B03) so that when 1.05 releases everyone has the same goodies.
And also makes it possible for everyone with a tune to stay updated with toyotas new changes.

 

Hey @dingel5 , does this mean you have to stay on Toyota's new calibration until Mat gets done?

I just want to be sure..

Am I on the right track?

 

Would this tune help for tire size 285 by any way? If anyone has 285s and installed this tune would you recommend it ?

 

Yes, can confirm
