In most cases the vehicle will have to be returned to the company that performed the reflash, or it will have to be taken to a dealer workshop so it can be set back to standard. Taking a vehicle back to standard after a remap can be challenging and costly. “When we start to diagnose vehicles, we’ll ask our customers to get it back to standard before we start to work on them, otherwise we can spend lots of time and money chasing a problem that’s not actually there,” explains Gavin.

According to Gavin, the biggest concern in the workshop is trying find a problem that may not actually be in the vehicle but in the remap. Unsealed 4X4’s Pat Callinan recently met with Gavin Bradford from Diesel Care to discuss some of the common issues found when trying to diagnose a diesel 4×4 that has been remapped. Remapping is the practice of downloading a different map into the vehicle’s ECU and opens up the possibility to change many parameters of a vehicle’s performance.” “They’re sometimes called “piggy-back” systems and can be removed easily unlike other forms of power enhancement such as ECU remapping, also known as flash tuning. There are several advantages of this set-up and, as demonstrated by Diesel Care, “The device is separate to the vehicle Electronic Control Unit (ECU) and is connected into the system harness by means of connector plugs. The Steinbauer Power Module is a plug-in unit. No footprint is left on the ECU, each module is programmed to a specific vehicle, ready to plug in and experience the results.” The Steinbauer Power Module is a plug-in unit, so it’s easy to install and remove. The diesel experts attest that the Steinbauer Power Module is “a highly advanced, completely programmable electronic computer module. Diesel Care says the Steinbauer Power Module is one of the easiest and safest ways to modify a modern diesel engine’s performance, which is achieved by electronically changing the engine management system’s parameters.
