Toyota Hiace

Every tradie needs a van,
that carries their gear and takes their men
from A to B, reliably,
and it's cheap to run, so it makes money.
The owner of this Hiace said,
I like the van, but the lag is sad,
I want to have some fun with it,
I need more grunt, can you do it?
Sure we can! - we said to him,
Just book a time, and bring it in!
We did the thing we like the most:
unleash the beast, adjust the boost,
enhance values inside its brain,
to get a pretty awesome gain.
Thirty horses went on top
the hundred-and-thirty that she got,
but what made owner shed some tears,
was the 100 extra newton-meters.
The lag is gone, that turned him on,
he thanked us all, the deal was done!

what you get

  1. We can add 30HP to the factory 134HP - resulting 164HP
    This helps the car in maintaining the top legal speed, which is typically a challenge for any vehicle on a hilly road. This is a result of horsepower utilisation at the high end.
  2. We can add 82N.m torque to the factory 343N.m - resulting 425N.m
    Currently, a strength of modern diesel is torque. The vehicle will have heaps more grunt down low, will have more aggressive city drivability, especially at intersections, green lights, etc. In addition also better towing abilities since torque is responsible for getting the dead weight moving until you reach travel speeds.
  3. We can extend the dynamic RPM range which is responsible to deliver maximum power and torque in specific revs. By widening this range engine will have no chance to get outside of the top performing torque range, meaning no more lag during shifting gears.
  4. We’d also recommend increasing the boost pressure, optimizing the acceleration mixture aka Air Fuel Ratio (AFR), keeping Exhaust Gas Temperature (EGT) down and adjusting injection duration. These will ultimately give you that smooth power delivery that you’re after throughout the whole RPM range.

fuel efficiency

Fuel consumption is another beast altogether and since everyone loves fuel efficient vehicles it’s worth to mention how and why engines can save dollars. There are 5 main factors that determine fuel consumption and these are:
  • engine controlling maps in ECU software
  • condition of engine
  • customized rims and tyres
  • driver’s driving style
  • terrain
What we can change is the engine maps and it increases fuel efficiency dramatically, but never forget about the other 4 factors.

How it is done

Click if you are interested in the detailed procedure...

Your Beast's is Engine Control Unit (ECU) has 3 protection layers.
  • a 16 bit password
  • locked OBD port
  • encrypted file system
Without being too geeky let’s just say the first stage of our work is getting through these protection layers one-by-one. Once that’s done we can start backing up changing the map files that are responsible for controlling the engine. We do it by modifying the turbo pressure, the ignition, the injection timing, the acceleration mixture and the lambda sensor values, which will enable us to increase the performance of your model by the following: The procedure is the following:
  • removing the ECU
  • establishing a connection to ECU
  • taking a full backup of the map files (recovery point)
  • modifying the map files (the actual tuning process)
  • uploading the map files to the ECU
  • re-fitting the ECU
  • test driving
This is a STAGE 1 tuning, meaning no hardware modification or mechanical alteration to power trail needed - it is purely an software programming work.
