ECONOMY

Provides an increase of approx. 4-5 MPG with a focus on economy and slightly less power in the engine's mid-range.

ECO + POWER

Provides an increase of approx. 2-3 MPG with a blend of both economy and an overall 18-20% power increase throughout the engine's power band.

POWER

Provides an increase of approx. 30% over a stock vehicle with a strict focus on power. Most customers report no change in fuel economy.

**COMPATIBLE WITH: KUN26 Hilux and all Diesel Toys Converted Tacomas, FJ Cruisers, and 4runners.

 
 
If you own a Hilux or Prado diesel, you’re most likely familiar with the plug-in boxes that are available. These boxes interface between the ECU and the engine (normally fuel injectors) and are essentially something called a pulse width modulator. This means that their sole function is to intercept the fuel injector pulses and stretch them out. This causes  the injectors to stay open longer, thus spraying more fuel. More fuel = more power, however it also means poor fuel economy and the litany of negative effects of dumping excess fuel into the cylinders.  These programmer boxes are known to be extremely prone to issues. Most commonly, the vehicle will go into “Limp Mode” where it loses all power forcing the driver to pull off to the side of the road to restart the engine. This is due to the fact that while these plugin boxes trick the injectors, the rest of the engine management system is not as easily fooled.  A host of onboard sensors are constantly providing feedback to the engine control module. If these sensors report something that doesn’t add up, the engine control module will decide there must be a problem and cut power to the engine.

 

We have learned that while plugin boxes seem like the easy solution to more power,  they should be avoided at all costs.  Tuning at the microprocessor level simply provides DRAMATICALLY more control and functionality. This translates into both BETTER fuel economy AND more power; something a tuner box could NEVER do. We have been tuning our own ECU’s for the last 5+ years as almost a side function of performing our D-4D conversions. We have tuned for US Military applications where reliability counts. We back our results with real world numbers so you can be sure our tunes are safe, reliable,  and time-tested. With the latest developments in the Toyota ECU-based mapping we can not only re-map the fueling at the ECU-level, we can turn off things like EGR, finely control boost, and really finesse these engines for HUGE performance gains. All while doing it in a safe, controlled manner. We back our tunes with a money back guarantee, we save your original files so for any reason we can refresh your ECU back to factory spec. We have a 24 hour turnaround for all of our tunes and we ship several ECU’s a week to the UK , Australia, the UAE. For more information, shoot us an email.
