2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Just got my kit & dongle serial sent to Matt.

 

Most likely Toyota’s overly complex logic calibrating or something

 

@Shellshock is correct. read up about this so you can understand what's going on if you have q's. if you want to get more into it, go to the OVTune Alpha thread.

 

Hi all.

Has anyone besides me actually tried to download, install and use this version of Techstream? I have tried a couple of times now, and I make good progress until the installation instructions say to "Install the MVCI Driver for Toyota TIS". This driver is not included in the download referenced by OVTune. And so, when I run Techstream and try to connect to the truck, I get an error message indicating that it cannot connect.

I am open to whatever useful advice might be provided.

Thanks...................... Frank

 

I read all that, that doesn’t say what is causing this particular change.

 

Change the OBD2 option in TS

 

Flash done. Warming up for 5 minutes then going for a run. Flashed the 91 file.

 

I didn't even get that far! All I get is a .rar file, but then unrarx says that there's no files in the archive.

 

And the verdict is???

 

holy crap, still no delivery for you?

 

Ok, just drove up to my dad's, about 25 miles away.
I took the interstate and the roads were snowy and traffic was slow. Speeds were mostly below 30-40 for 2/3 of the ride.
Let me start off saying that the throttle response is amazing and the torque down low (at like 1200-1800 rps is night and day) Yes, the response and torque are still amazing as the rpm's climb, but because of the driving conditions, I notices a HUGE difference. More on that in a sec.

I notice that 3rd and 4th gear were amazing at low speeds. I was in 4th the bulk of the drive and never felt like I needed to downshift to get going as traffic speed up some. I did notice (weather the tune had something to do with it unsure at this point) that I could break the end loose in 3rd gear with moderate-light to moderate throttle. Keep in mind that the road was snow covered and slushy. Not 100% it did that b4 the tune, but I have had the truck in those conditions before and do not recall it braking loose that easily. Not going to lie, that gave me a bit of a heart jolt because of traffic and the conditions. Hence, where my thoughts on 4th gear come in. I decided to shift into 4th to keep the power delivery slug-ish, as it were, to avoid the rear end getting loose. It was amazing. I never felt like I had to shift to 3rd to maintain speed or power as needed based on traffic and increase in speed.

I did shift into 5th a few times on the trip and it too felt great. Granted the speeds were about 40-45 when I was using 5th, but it still felt great and never overly boggy. I could input some throttle and it would not hesitate or bog like on stoke tune. Yes, If I gave it too much throttle it would, but remember the conditions and speeds were are talking about for this test drive.

2nd gear is a WHOLE new beast. I can not believe the difference 2nd gear is at low speeds! This is truly amazing to me. The truck felt responsive and eager to give power at low speeds or just lug around. I was able to come to a rolling turn and not even feel like the truck was going to sputter out like on stock tune. It just help the power and torque and off we went.

I noticed at idle, the truck sits about 600-700 rpm's. (I forgot to plug my OBD plug back in b4 the trip. I will use it for the return trip) It idled smooth and very stable.

Over all, the truck felt great. I am eager to get out and do some 4lo driving and might try for tomorrow after work for a little bit.

I will report more on the ride home if I fell or notice anything else.

 

@OVTune please dial back the throttle a slight bit like you mentioned for 1.03B

good report.

after putting a few hundred on myself, i am now saying for sure the throttle ramp needs to be dialed back a tick. just a tick. i am having a total hell of a time on wet roads. we're slammed with rain right now so I'm getting a good window to find limits. to be normal with traction and not constantly breaking traction and bringing on VSC, i am having to baby the throttle too much. way too much. it's like when i had the Pedal Commander on a too high setting. i am having to split hairs on the throttle position, feels like maybe 1/8" of travel or less. need more travel to modulate.

 

Got the kit just waiting for Matt to send my registration key.

 

ah ok. good luck over the weekend. go pester him in the Alpha thread. and send hima couple emails. he's good with PITA players it seems.

 

Ups got delayed due to the weather so they say..

 

I agree about the throttle if this will be the norm. Granted I did forget to mention I had boots on and that might effect how I can feel the pedal and make adjustments. But still, it was very responsive. I wonder if the 87 tune is just as responsive? I'm going to give this file at least 500 miles, but hope the throttle at small inputs becomes a bit better to gauge. Time will tell. More to come

 

Same here. There was ice here yesterday, that was not a fun time. You are either speeding up or slowing down, hard to maintain speed. Doesn’t need to be a lot of change, just a touch should be sufficient.

 

exactly.

 

Yes it is. I’m running 87. It’ll cut loose when you want it to and when you don’t.

 

I get to the registration page on version 119 and 127 and it won’t accept there key with a bunch of 11111....at the beginning. It just pops up with a new register tech. Software box.
