Also, steer away from cheap plug-in ‘chips’. This is important as having a ‘one-size-fits-all’ approach with a ‘Car Park Tune’ (where a file is downloaded into your car, well, in a car park or somewhere similarly shonky) simply isn’t good enough. For a start make sure you have your Ranger tuned by someone that both has and uses a dyno. Advertisements, testimonials, and general hype can overlook the basics you need to stick to with your Ranger. In fact, it really doesn’t matter which of the different 4X4 pickups/utes we are talking about, getting the ECU programming right is the biggest single thing you can do to improve the engine’s performance. Start with the engine management system, we say. Sure, there’s plenty more you can do with the Ranger’s 3.2L engine but our list will hopefully get you started on the right track. We’ve looked at the things that you should think about doing first, to improve performance (without affecting reliability or longevity) whether you’re towing or off-roading. With that in mind let’s answer the question in every owner’s mind, ‘What are the top 5 performance tips for my 3.2?’ Some of these modifications work and some of them, well, if we’re being kind, let’s just say are not so effective. No way! But, in the end the average consumption is what really matters.A quick scan around the web will show that there are a ton of modification options available for the Ranger to ‘make a good thing even better’. But, there is no way that the same car driven hard would save fuel with a chip compared with stock. The fact that a chip may save fuel is due to the perception of the driver, the car moves quicker and you do not push it as much anymore.

So, the stock software in the ECU will try to compensate, trying to bring things back to normal, which means more fuel, boost => more power. What the powerbox does is to alter the values from the sensors, such that the ECU will think the engine is running in a different regime in the current maps (which stay the same, opposed to a proper remapping).

However, the dealer may not distinguish them from an honest fault, at least not from the first attempt.

The way any powerbox makes more power is to inject different values than the sensors are normally sending to the ECU, which may look abnormal, so the ECU may log them as faults. The recording is not done by the DPChip (or any other for the matter), but by the car's ECU.
