URD MAF Sensor Calibrator

[jordanrb81]

To the OP this is great and thank you. I spoke to my very trusted mechanic about doing a COI either AFE or K&N and a Borla Cat back exhaust and he said well you can do that but if you don't do anything to the MAF sensor then the ecu and engine will actually work against the mod. you basically need the MAF to tell the ECU what you've done or, like on other threads on here, you'll find potentially less power and worse fuel efficiency. I found a JET MAF that claims to do just that, but having been to the website of the one you put in, knowing you can send them exactly what modifications you have done makes quite a lot of sense. it's my understanding that these three modifications really work best as one combined upgrade. I thought I'd let my engine break in a little more as it still has less than 5k on it, but this is very helpful. it sounds like you've already got the COI AND the CAT back exhaust, is that correct? thanks again!!

Yes, on the CAI and Borla Cat. Not available at the time was the URD CAT back at 3"OD. Suggest you look at this as good alternative to Borla. Not that I am unhappy with the Borla.....

Love how you try and say 'hey guys check out this cool thing' and you get sidetracked into a debate about air filters or some such.

Can debate it forever and have been...

I like the URD MAF too!
I cant say as to how the MAF works but it does.
Seems like it even shifts better.
I hit 305hp :gossip: on the scanguage2...I know its not real hp measurement...we don't have to debate that here, thank you.

/cheers

Depends how you look at it. Others took the post down the road of Wet/Dry/OEM filters. URD MAF works great.

My experience after running them for awhile (Wet/Dry) No Problems

That's what I meant, I have had no issues with K&N either.

I’m starting to like the sound of this thing more and more.

:lookout:

I just put one in 2 days ago and dig it. It’s not my 650hp Evo but a little bump is noticeable and awesome

 

[TRUSTYAXE]

Anyone else have any experience with these? I did some searching and have only found positive reviews, mostly on other vehicles. I’m surprised more of the sprint booster advocates haven’t tried it yet.

Had mine on for a couple tanks of gas now...easily getting and extra 50+ miles out of a tank. Still more pep too

Interesting, can you post pics of it installed? Did you use the tuning software? If so how did that go?

I have one, with TRD intake and URD TRD intake tune on it. I have nothing but good things to say. I was one of those people complaining about power not anymore. It smooths out the throttle and power band along with giving you more power. Also makes the pedal less heavy feeling. I bought the URD Map sensor and Sprint Booster at the same time. I installed the URD Map sensor first. After seeing the how well it performed I sent the Sprint Booster back for a full refund. I also don't see need the Sprint Booster at all if you have the URD Map sensor. I get around 320 miles per tank now with 32" tires and 2.5" lift.

I think the 4 runner is a great vehicle. I'm the type that's not happy with a complete factory vehicle also. With that being said I think all 4 runner 5th gen owners need the following to correct its shortcomings.

TRD intake/screen removed from intake lid
URD MAP Senser with TRD intake tune

The bushings give you less body roll in turns and a closer ride of a KDSS equipped 4 runner.

I will grab a picture for you a little later today. I just had URD put the TRD intaketune on it. Didn’t feel the need to go have it tuned. Living in Denver just robs power from the vehicles. This helps get some of that back.

I installed the URD MAF Sensor and immediately felt a difference in throttle response and positive difference in MPG.

I've been sitting on a Sprint Booster since purchasing the TRDP, so a week leader installed it. Set to Sport Mode 4. It does make a huge difference in pedal responsiveness. My opinion is worth the money just for increase in throttle response vs modulating the accelerator.

Interesting you guys are seeing such positive results from a MAF calibrator..

I don't get the MPG improvement though.

I do agree these things are calibrated like garbage from the factory. I really wonder what they were thinking...or if they even spent any time on it.

Ok here is the engine bay. Unit is on the firewall and you can see 1 plug on the MAF plug. The other is on a coil plug unseen

I can’t explain the bump in MPG either but it is there for sure. Haven’t dipped bellow 20 mpg since I put it in. That will definitely change soon as lift and Gobi rack go on in a couple weeks. First tank after install I filled with ethanol free and got over 400 miles on the tank.

Just curious if there any longer term reports on this. It seems by resetting the ecu by either pulling the EFI fuse or disconnecting the battery the truck is back in learning mode. I've also noticed that the folks are running premium after resetting everything.

There a quite a few things changing to really contribute all the gains to the MAF sensor calibrator. It would be interesting to see what changes with just installing the MAF sensor calibrator and leaving everything else the same.

Finally got mine. They were out of stock as I ordered back in January. Hardest part was trying to find an ocd friendly spot to mount it. Leaving the battery off overnight and we will see how it goes tomorrow.

Yours looks so much nicer than mine. Im going to clean up my install tomorrow now

Just ordered one. Hope it’s all that it’s cracked up to be.
