Tacoma ECU Tuning for 4.0L

when was the last time you updated the handheld? I've added this one, please let me know if it is still not recognized

 

Any progress on 30433300? Tried to update last night, no dice.

 

Less than 12 hours ago (yesterday). I'll try again in an hour. The latest firmware that my handheld grabbed is V1.50

 

There was a recent member posting that his connection was the culprit. May or may not also be your issue perhaps?

 

This is important to me as well. If it costs $500 to repair the sais for it to fail again in 5 years, I would rather spend that money on a tune that gets me some power and mpg and ditches the pump software.

 

Thanks Tor, but nope... my Internet connectivity looks good. The handheld is able to communicate to the repository and grab "new" protocol and data files. The latest FW on my handheld is V1.50.

@OVTune
The error still exists. ECU 3YWG2900 is still not found. Here are my steps:
1. Plug in handheld to my laptop.
2. Launch OVTuning software. Software identifies my handheld.
(It does it's automated thing. Downloads files, etc...)
3a. OVT software finishes updating

3b. Take my handheld to my truck.
4. Plug the obd2 plug into the odb2 port. Plug the other end into the handheld tuner.
5. Handheld powers up. Then I turn my key so my truck is powered on (engine is NOT running)
6. I follow the instuctions (Setup, vehicle, engine, etc)
7. Says stock ECU file is not found. I hit OK/continue so it Attempts to pull the stock ECU file.

8. Errors out with ECU calibration file not found. 3YWG2900

This was performed at 0925am (Pacific) Mar 5th.

 

Same process for me, but spits out a different calibration error.

 

i'll try again, any updates on 304A3000?

 

Toyota issued a warranty for this. You should be able to get reimbursed. Pretty sure there is another thread on here about it.

 

Not sure if this applies to Canada but....

Doesn't apply to Canada .... sadface

30461100

30449300
30442200
30456000


secondary air injection can be fixed yes.

new handhelds arrive this week so I will explain all the features in detail. (the features are the same with the v3 handhelds. these are v3+)

 

@Brice , do you vaguely remember the code of mine? Is it the same as yours, 30456000?

 

I wanna say it had a 6 in it but I'm not too sure. We should have taken a picture. And no, mine is 30426300, atleast that's what the handheld says.

 

Guess we need to look back and see if that one has already been submitted.

 

It'd be nice to get a tow tune.

 

+1 to all of this. Followed same procedure as SUMOTNK (via cellular hot spot) at about 2130 MST. Still awaiting initial upload for 3YWG4000.

 

Looks like the first batch is sold out. Waiting on the 2nd batch and results. Will try to be one of the first on the buy. Kind of got lost in the information of 98 pages but could you request additional tunes after the first sent to you in case you get more performance parts? This would pretty much would feed my will to start slowly adding goodies to my truck.

 

So does anyone that bought one of these even have a working tune on their truck yet?

 

A handful of people do I believe. One has been bench tuned since late summer/early fall.
