Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Morning temps are around 40 and afternoon mid 60s, overall maybe 10 degrees less than before. Also I flashed 1.05 91 Base tune yesterday and cleared the CEL but the fuel economy did not improve. I have a feeling that the winter gas mix+colder temps+new exhaust that is not tuned for have played a role in fuel economy. Its sad to go from averaging 18.5 for over a year to 16 in a couple of weeks. I have a set of OVTune catted dump tubes so once I get them installed I will flash the proper tune and hopefully things will improve.

 

Purple dongle.

 

@OVTune the 04B04 stock exhaust 87 octane map is linked to incorrect PCM file. Can you please fix?

 

take out the +4.88 part of the link. They follow a standard naming convention

 

Thanks! why didn't I think of that

For those who is looking for the PCM 04B04 stock exhaust 87 octane, the link is:

Yeah, 40's will burn alot more fuel. Sadly your MPG won't go up until next spring.

I haven't tried any of the new OVTunes but I was tired of false promises and there is always something that needed to be fixed in the tunes. I still held out hoping things would change, just sold my unit today.

I've had no issues whatsoever with the updated OEM 04B13 tune. Truck is always going to be under-powered naturally aspirated.

 

Just be patient and let it break in.

 

I can say the 1.05 and 2.0 betas have really help my stock drive. Since you still have the dongle is your ECU supported for the newer tunes? I mean you have it...let it free

 

Ah, the first time I used the octane learning tune and missed it was a GL tune and had ECT on....good time good times.

 

the purple one was the original dongle before the small ones

 

You do realize these have all been development tunes, like the title of the thread says? Anyways, your loss.....these new files are awesome.

 

Not sure what’s funny, he’s right.
Stock tune is garbage.

 

Exactly......that's my reaction to stock tune.

 

It's ok, let him laugh. Joke is on him

 

Yup

 

Just got the instructions for the handheld. Does anyone know what we do to flash back to stock tune ? I upgraded from 03 to 04 but my stock tune was saved as 03 ECU and you cant flash back once you upgraded to 04. I sent a ticket but thought i would ask here also. Thanks
I am using the accessory handheld for dongle.

 

For you 4.88 folks, what's your favorite build so far? Mine is 0944 87 octane and im on 04b04 but I haven't tested the latest one yet, 19800.
