VMN Hilux/Vigo/Prado LandCruiser Diesel Performance Chip

VMN has released a Diesel Performance Chip for the Toyota D4D 3.0 litre common rail fuel injected engine manufactured since 2006. It can be fitted in 20 minutes and delivers performance increases of around 30% over standard performance in both power and torque.

The principle is simple and involves connecting our chip tuning kit between the original computer and the injection system of your car. The chip tuning kit is fitted with automotive quality connectors and not the cheap computer connectors found on inferior kits. This means that they can be quickly and efficiently connected without having to cut or solder wires together. They can simply be unplugged or removed very easily leaving no physical trace in the vehicle's engine or computer memory, handy if you take your car in for servicing and don't want the dealer to know!

Furthermore, as the manufacturers' specified operating tolerances are never exceeded, you can be assured that our Performance Chip Tuning Kit will perform brilliantly and within the engines capabilities.

This chip can be self installed in 20 minutes, has four adjustable power settings and includes a two year warranty.

Anyway, before you read much further check out what our customers have to say about this product here:

It is very simple to fit and comprises of a wiring harness that goes to each injector. It is simply a matter of disconnecting the factory wires from each injector, connecting them to the wiring harnes and then connecting the harness to the injector.

The other end of the wiring harness has a red and a black wire that are used to connect to the battery using the provided spade lugs. The shorter black wire is optionally used to disable the chip if it is connected to earth via a switch.

Before launching the Chip in Australia, VMN undertook independent dyno testing on a 2007 Auto Hilux with standard exhaust and air filter. This graph show the difference between the factory performance and the minimum power setting:

In this instance, the red lines shows factory performance wthout the chip enabled and the blue lines show perfomance with the chip enabled at the minimum boost setting. The the lower line shows torque and the upper line power. Even on the minimum settings, the performance graph shows significant improvement.The following graph shows the range of increase in performance between the minimum boost setting and the maximum.

Note that the second graph includes the minimum power setting again and introduce a new line for the maximum power setting. (eg. te red line in the first graph is exactly the same as blue line in the second).

So let's have a look at what all this means in a table form:

The VMN chip on its minimum setting outperforms many chips on the market place today at a very attractive price point around 30% cheaper than other competing products.
