Tacoma ECU Tuning for 4.0L

Found it, it's an issue we have at the moment with zendesk, tickets are not populating properly.

yes we can upgrade N/A ECUs to TRD + tune

 

@OVTune same boat as @TacoSupreme2012, I sent updated data about 2 weeks ago. This is regarding Order# 4287
Request# 6117

 

We are working on this, we have a problem with zendesk tickets, you do not need to resend, we are waiting for them to fix it.

 

@OVTune
Will it be much longer? You have my data in the PM.

 

Good for you Matt! Good thing you had plenty of experience being busy. It’s the best! Now your test will be multitasking and balance work/home. Congratulations

We are closed from 3rd to the 8th, but we are still working on finishing pending 4.0L tune files. We did have an issue with our zendesk but this has been fixed.
For the 4.0L (only 4.0L) some files and ECU versions take additional time for us to build support for, due to the inability / impossibility to gather the BIN data over OBD. This makes tuning them *dependent on your ECU ID* a bit slower.

 

Ok. Thanks for the update.

 

X2. I’m still patiently waiting too. I know your a busy guy with a lot of plates spinning.

 

Calibration versions for support today (tunes)

04413 (04412 update)

Thank you! I received the tunes and upgraded from 04680 to 04681.

My preliminary impression from a 15mi. drive on the 87 tune for a stock N/A manual 2012 with TRD Offroad package is that it should have come from the factory like this.

It's easier to start from a dead stop and easier to shift in all gears because of the improved throttle response. It definitely feels more similar to my '96 Tacoma now, in that regard. Accelerating with the A/C on is better (still have to give it the beans...doesn't add power) because the engine feels smoother and sounds happier revving out.

Overall, I'm happy with it and I'm sure I will become even more pleased with it as time goes on. Having to shift many dozens of times a day, this tune has improved my enjoyment of driving the truck.

 

@OVTune any chance you have already or will be looking at the 1uzfe down the road? Or not a platform you would go after? I'll soon have an older non-vvti ls400/1uzfe I'll be looking to tune.

 

Would love to do more platforms but Tacomas alone keep me too busy

 

Very interested for my 4.0 1GR. Can it be used to calibrate tire size for speedo? If not can I run a programmer for this and also run the OVTUNED as well?

 

So Iv read the first like 100 pages and then skipped to the last like 60 pages and I still don’t know if this is something I could benefit from. Most of the trucks that have this seems to have different sized pulleys or some kind of exhaust mods and they are s/c that I don’t plan on doing. All I have is a trd exhaust and 285/70/17 nitro ridge graps that weight 49lbs each. Will I benefit from this with my setup?

I’m mostly looking for increased mpgs and I drive pretty conservatively ranging from 18-17 mpgs mostly highway driving in SoCal.

 

Has there been any N/A guys with tune that have some dyno numbers to share? Or done some just 0-60 times to compare to see improvements?

 

I run my tune in 87 octane mode for fuel savings. It's a truck, I dont do stoplight races anymore now that I'm an old man lol

 

Oh I know I'm not a race truck by any means lol the 0-60 reference was just to see gains. I'm mainly wanting to know hp torque gains to see how worth it it is. I'm up to a 34" and could use the power before I regear

 

@OVTune .....any progress with my custom tune ?

 

Did you mpgs go up after installing this?
