Description

URD MAF Sensor Calibrator

*If you plan on installing a turbo in the future, please buy the MAF calibrator with MAP sensor option*

Have you been looking for a cost effective way to tap into some of that hidden power?  Have you been looking for a way to get that expensive cat-back exhaust system to live up to your expectations?  Has your expensive aftermarket air intake system let you down?  You need the ability to retune your ECU for these aftermarket upgrades to get the performance gains you expect.

The URD MAF Sensor Calibration Unit allows fuel curve retuning to find that hidden power you are looking for.  The URD MAF Sensor Calibrator and your tuning will tie all of your performance modifications together, unleashing all the power available from them.

The URD MAF Sensor Calibrator is basically the fuel control half of our very successful URD MAF/Timing Calibrator that URD included in our Supercharger Performance Upgrade Kits for years.  We know that not everyone needs timing control, and removing the timing control function saves you a lot of money.

The URD MAF Sensor Calibrator intercepts the signal from the Mass Airflow Sensor and remaps it optimizing the fuel mixture for the best power and performance.  It is the ability to retune that optimizes your modifications allowing them to work together as they should.

It is programmed using included tuning software based on manifold pressure or throttle position (depending on version) and RPM.  The software has more resolution than any other end user fuel computer in this price range.  You will need a Window PC and a serial port or USB to serial adapter to connect to the unit for tuning.

We offer two basic URD MAF Sensor Calibrator versions. One is primarily for normally aspirated vehicles that use the signal from the throttle position sensor as the load scale indicator and one with a Manifold Absolute Pressure Sensor (MAP Sensor).  The unit with the MAP sensor senses the manifold pressure and is primarily for engines that have forced induction.

The unit for normally aspirated engines can be used for:

  • Optimizing the fuel mixture for best power on stock or modified engines
  • Correcting MAF Sensor error caused by aftermarket intake systems
  • Remapping the fuel curve to compensate for high flow headers, exhaust systems, and cams

The unit with the MAP sensor for engines with forced induction systems can be used for:

  • Optimizing the fuel mixture for best power
  • Retuning the ECU for larger then stock fuel injectors
  • Retuning for increased boost levels


Here is a typical example of how effective the URD MAF Sensor Calibrator can be.  This is a dyno chart from a totally stock 2005 Tacoma X-Runner.  As you can see there was a hidden 15 Rear Wheel Horse Power (RWHP) just waiting to be unleashed.  Results from totally stock vehicles typically yield 8-15+ RWHP.  We even found 15 RWHP on a totally stock Camry. 

If you have been considering some other end user tunable fuel computer for your vehicle we think you will find that most of them have the resolution of a very dull butter knife and cost you much more then our solution. 

Our map table is truly three dimensional and has 61 load columns and 16 RPM rows for a total of 986 map table cells all of which are directly accessible.  Each cell has 200 levels of adjustment.  There is nothing else out there that is this easy to tune with this level of map resolution in this price range, NOTHING.  Only the best from URD.

The units can be used on any 0-5 volt sensor, but are primarily used to recalibrate the MAF Sensor signals.  If you wish to modify some other 0-5 volt circuit based on RPM and TPS/Manifold Pressure the unit can be applied to your needs.

The unit ships with the tuning software and a vehicle specific connection guide for the vehicles listed below.  Just select the vehicle you have and the appropriate guide will be included for you.  If you have some other vehicle not listed, the unit will ship with a generic connection guide to assist you in your installation. 

These are great units. We have even used these calibrators on Lamborghini and Ferrari MAF Sensor based vehicles with fantastic results.

Please contact info@urdusa.com with any questions.


When placing your order please tell us what vehicle, engine, and year you will be installing the URD MAF Sensor Calibrator into and what perfromance modifications are already installed on the vehicle.  This will allow us to include the correct installation guide and in some cases we have a calibration file that may perfectly fit your combination and will pre-load that before we ship the unit to you.  We have many calibrations for the 1GR-FE and 2TR-FE engines with many of the more popular intakes.  If we do not have calibration file specific to your combination a "BLANK" map will be loaded so you can install the unit and the vehicle will drive normally until you start your custom tuning.

Please put the info requested in the COMMENTS box in the check out.

Just installed my maf cal today. Instructions were really easy to follow. I was a little scared about splicing into the ECU, but after starting her up and taking her for a test drive, I could really feel the difference. It feels and sounds so much smoother now. It lunges in 2nd gear and TRD CAI sounds mean............Best power mod buy for the buck....and tuneable....the urd cai map that was programmed in feels like its on the money..Mahalo to Gadget, Brian and Robert for hooking me up......Auuurriigghhhtttt..

Received in 2 days, and that includes Gadget loading the map on the calibrator. I own a 2010 4.0L (6-Speed) with K&N intake and Magnaflow muffler. The calibrator did a great job of improving overall responsiveness and power(seat dyno'd of course). Also, appears to of increased MPG's by about 1 - 2. Install took a little less than 2 hours. I took a different route and cut the ECU wires. Then, used marine grade butt connectors with heat shrink shielding to place the MAF calibrator in-line. Thanks URD! Adam..

This little item is awesome! It was fairly easy to install. I have a 2007 double cab with auto trans. Where my truck would just sqeak a little at takeoff before, now it will smoke them on command with a CAI, cat-back system, and the MAF calibrator!! Also, running a 14.7 quarter mile time--faster than any other N/A V6 truck I've seen so far...

I purchased the Urd Maf cal unit for my 2010 2.7 Tacoma and absolutely love it. The truck pulls so much harder and runs much more smooth. It really makes a difference with my headers and CAI. Thanks for everything...
