Custom ECU Re-Map and Common Rail Diesel Tuning

GO 4x4 can Custom Re-Map your diesel 4WD vehicle, providing increased power, torque, economy with better driveability and response. A Custom Diesel Tune to improve performance from your tow vehicle, tradie ute or off-roader can be tailored to suit your needs, with the same vehicle having many different tunes, depending on use. Every Diesel Tune is provided with a 2 Year Unlimited Km Engine & Tune Warranty.

GO 4x4 specialise in Common Rail Diesel tuning or Re-Mapping, providing a custom user-specific tune to diesel 4WD vehicles, diesel cars and machinery.
It is not a preset package tune from Russia or Europe (where air temperatures are vastly different to Australia), that is then downloaded into your ECU in a flash. Nor is it a “plug-in” or “solder-in” chip.

Diesel Re-Mapping optimises performance for the same or less fuel. The Diesel Tune is setup according to your use of the vehicle. You’ll need to advise us what you use it for, and what you find lacking.

For example: Towing a Van occasionally, Towing a Heavy Tradie Trailer every day, carrying a Water or Fuel Tank for a Fire Unit – there are so many uses, the tunes vary substantially.

Our focus is drivability, widening the useful RPM range, to change the entire feel of the vehicle.

To achieve this, we go into the ECU and change hundred’s of tune settings – the relationship of fuel, air, timing sensors (MAS, MAP, Crank Angle, TPS, EGR, Boost, Cam Timing, Injector Timing and Pressure, AFR’s) – a myriad of networking that generates the factory tune.

As you can see from our 2018 VDJ79 Dual Cab, Stage 3 Kit, there is a dramatic increase in useable torque. 325 to 622nm. That’s a 92% increase!
Power lifts from 109kw to a respectable 144kw, and this is achieved with less fuel.

You can see the red line on all graphs is obviously the ‘After’ performance. Power and Torque are obvious.
The AFR is Air Fuel Ratio. The higher the line the more Air, ie less Fuel load, leaner mixture. Most tunes achieve a 5-15% fuel saving, but the maximum possible is 40%. In theory it could pay for itself over time, but you wouldn’t do a re-map just to achieve better fuel economy

If you run down the graphs at the same RPM, you can see the red line is above the blue in the AFR’s and all other specs: Power, Torque, Boost are up while Fuel Load is down, all the way to 2300rpm. All happening at the same time. And even when the AFR’s drop below the standard setting, it’s not by much.

It’s not magic, it’s using the existing ECU and sensors, just changing how they interrelate to each other. 

Tune Options:
Stage 1 = Tune Only.
Stage 2 = Stage 1 plus DPF back Exhaust Kit
Stage 3 = Stage 1 plus Turbo back Exhaust Kit
Stage 4 = Stage 3 Plus Hi-Flow Turbo Upgrade
Stage 5 = Stage 4 plus High Capacity Intercooler Upgrade
Stage 6 = Stage 5 plus High Flow Injector Upgrade

To go further, hard parts need to be changed. Upgrading to a higher capacity turbo and hi-flow injectors.

To protect your investment, we retain the factory built-in ECU safeguards that protect your engine and driveline. We take a back-up copy of the original and new tunes, dual storing them at different sites. If it was ever needed, we can restore the original tune.

We also provide a 2 Year Unlimited Km Engine & Tune Warranty.

If you are interested, you can make an appointment to drive our 2018 GXL Dual Cab. With the ECU Re-Map & Exhaust Power Upgrade (and Auto Transmission Conversion), you’ll absolutely love the result!
