URD MAF Sensor

How's the pickup and go on this mod? Kinda on the fence of purchasing and wont be able to return if im disappointed with it.

 

Has anyone seen any specific HP gains with this or is it just the seat dyno method? Just curious if it is worth the time and money?

 

Honestly, it says on there website that it helps mods like intake work better. For me it seems to run a bit more efficiently. I only had it for one gas tank and I still have a quarter tank left. So im hoping it will atleast improve my mpg. Was getting 17.1mpg-17.6mpg mixed driving. If im getting 18.5mpg-19mpg mixed then ill be happy.

I didn't feel any noticeable difference with a $200 something equipment that only took me less than an hour to install. So it is worth time bc I didn't have to do much and im hoping to get slightly better mpg. I am not going to do any actual dyno and Im sure no one else is going to do any dyno unless they actually install a supercharger.

If you guys want to know more or have any other questions then feel free to message me.

 

So no noticeable of better acceleration at all? Im assuming you got an intake and/or exhaust? If so, by chance did you get an uploaded map from URD to go along with the bolt ons?

 

the URD MAF does this in simple terms

More air flow in due to CAI >

it sees the air flow signal from the MAF.
amplifies the signal based on air flow and programmed curve charts inside URD module with Throttle position
sends that signal to ECU telling it there is more airflow there at current throttle position that actual TP is programmed in ECU at
This then makes the ECU add more fuel, timing, and AF ratio to get optimum burn.

There are many factors that affect engine performance.

Barometric pressure
air temperature both exterior and underhood Intake temperature. (temp of air inside motor before combustion - lower temp = more power)
Fuel octane
Air Flow both CAI and Cat Back/delete exhaust. Free Flow. Some engines need some backpressure.
You have to remember Toyota is a very conservative tuner of their ECU's so they are programmed for efficiency and longevity - meaning its hard to trick the 4R ECU into superpower mode.

I hope this helps.

I have the URD MAF module and I am pleased with it. I understand my expectations too.

 

Looks like a great trail (Round Knob) - how far would you say that is from Chattanooga? I've got property due west of Chattanooga we visit a couple time a year - the area looks similar to mine but I'm always up to try something different.

 

Okay - that said about performance improvement how would you rate the improvement compared to the $300 (+-) one gets from the Pedal Commander?

 

What a joke. Why waste money?

 

Pedal commander does nothing more than remap the drive by wire response curve. That why it has different settings.

you are not adding more fuel or air you are only changing the voltage going to the electronic throttle to open faster.

If Im not mistaken some "pedal commanders" out there have the ability to go the other way and smooth out the throttle even more for rock crawling and offroading.

Where as a Cold air intake is adding more air - URD is remapping the actual sensing of the mass air flow sensor telling the ECU there is more air flow - thus ECU adds more fuel.

 

Almost got me again. Get me once, shame on you. Get me twice, shame on me LOL

 

URD MAF up for sale. Listed in the marketplace. Went with a full YotaWerx tune.
