2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

FIFY

 

That's odd, because OP has already scanned stock 18' ECU files and said there is no change...

 

I had that as well with the stock tune. 103 - 91 tune it happened a little but that was only when it is really cold out and the truck wasn't fully warmed up. I can say that with 103B and only having it for 1 day it hasn't happened yet. I will keep an eye out for it tomorrow morning and report back if I experience any bucking or hiccups. So far this tune is much better. All the minor annoyances are gone. Now we just need to have proper engine braking and perhaps address slight rev hang ,hopefully that will be an option with future tunes. My truck is pretty quick now or should I say "fast truck" - If anyone was on the fence about adding full spec U exhaust and a cold air intake don't be. It has all come together very nicely. Loving my truck........

 

I had 800 miles on the truck. Why waste time?

 

Hey has anyone done the tune and done a lot of driving off pavement? Has the tune effected your Offroad performance for better or worse? Interested in getting the tune but don't know enough about it.

 

2018 ECU files for 87 and 91 sending out

 

I didn't get mine, did you miss me?

 

You get yours last

 

He sent you mine.

 

The 18 has a different ecu.

 

I just realized I'm in the M/T thread. But AFAIK the auto ECU ENGINE CODE has not changed for 18.

 

They are sent now

if you guys run into any problems let me know right away

 

Thanks Mat

 

Sweet! I could kiss ya.

 

@OVTune I was wondering what kind of hardware and software/app is available to do some data logging that I can share. Using my phone (Samsung) and a bluetooth obdII adapter would be preferred.

 

i haven’t received the email.

 

@OVTune are you sending mine out tonight too?

 

Very excited here after reading the 1.03b experiences. I know I can purchase & load up the tune asap but going to hold off a bit for my truck to break-in a little more. Bought a 2017 and only have 180ish on the odometer so far. I am curious about @OVTune unlocked in this latest version (not proprietary stuff) to pick-up the low end torque but just the general idea.
Is the Atkinson<->otto timing modified or something? Does one kick in sooner/later than the other? I could be wrong but from the latest updates on 1.03b it almost sounds as if direct injection / otto kicks in on lower RPMs rather than later or under heavier load like it does in stock.

 

Snail mail for you.
