performance for 07 taco

Hey PB, very nice truck. I need your help w/ the MAF calibrator.I am a wrencher, can jet a quad carb but haven't ever electronically tuned an engine. I work for Toyota Sales, asked a couple young techs that have x-runners about the MAF calibrator. They said my MAF sensor is now automatically compensating for the cold air intake and JBA headers and magnaflow exhaust that I had installed. They didn't think it was worth the extra money.I keep hearing about the MAF calibrator and read up at URDUSA. They say you need scanners and? to measure? Well I called a local speed shop(Delaware), they recommended another shop that had dyno. After calling them they said they don't have a 6-lug for dyno and they weren't into electronic tuning. I found that a little strange. Now back to square one. I'm sure with instructions I can hook up wires, set-up computer and software, but from there will the instructions be easy enough to reset curves, etc? Does the maf calibrator really make a big difference. If so maybe I can find somebody to do it in Philly or Balitimore. Thanks for any advice Tacochef

 

The stock fuel mix is usually way too rich because of the sensors that Toyota uses. They are not calibrated well enough, so toyota makes them run the engine rich. An MAF calibrator is very useful when you are adding lots of intake and exhaust upgrades. The MAF helps you get the air fuel mixture accurate.

The MAF calibrator comes loaded with a general setting that will improve your air fuel mixture, but if you get a Wideband you can see exactly what your fuel mix is, and you can fine tune it. A wideband sensor goes into your exhaust system. You read the temps. Then you use a laptop to connect to the MAF calibrator, and you adjust the settings accordingly. Once you are done you disconnect the computer and the wideband.

 

Thanks PB!

...does this MAF calibrator apply a constant or dynamic correction?

 

This is the route that I am going...

As I said in another thread. I talked on the phone with URD 30 minutes after I wrote them an enquiring email. They told me that in a few weeks they will be offering a package with the MAF Calibrator and Wideband Sensor.

For those of us with a 2.7L, this is the way to go! It offers the best performance with the least modification.

 

Save your old parts. Warrenty stuff you know!!!

 

the V6 4.0's definitely do come running rich as is, modifications like a cold air intake usually make it run even richer.

The URD MAF calibrator gives you control over the fuel mix so that its not running so rich.

Even with intake/exhaust i would highly doubt you'd get anything more than 10rwhp without that calibrator. It's well worth the money.

 

Does anyone know why the 07 v6 is 236hp and not 245hp like the previous years?

 

That question is kinda Off Topic, but....

Your 07 has the same actual HP as the 06 and 05. Toyota just changed the method that they use to measure HP. The new method is more realistic.

A 4.0 liter Tacoma actually puts out about 195 HP to the wheels.

 

Any dyno results? I've scoped the URD page and missed them, if they are there.

 

Well the results are gonna vary with the number of mods done to the truck and how correctly its tuned.

URD claims their truck saw a 31rwhp gain using their:

3" Exhaust
Y-Pipe
Cold Air Intake
MAF Calibrator
