Common-Rail Diesel TuningAdvanced Diesel Tuning Module

The GeoTune™ Diesel Tuning Box is a quality Digital Diesel Performance Tuning Module and it is a part of TruCore™ product range BMconversions offer.
The Advanced Common-Rail Tuning module we offer is a high quality device designed and manufactured in the UK, for UK climate and extensively tested with the UK fuel grade so you benefit from flawless operation, no error codes or warning lights and silky smooth power delivery.

We chose our supplier not because of the fancy box packaging. Our choice was made purely on the result and customer satisfaction this product receives.

Our High Quality diesel tuning boxes offer:
- a wide range of adjustment to suit all driver preferences;
- rugged, hard wired cables with no computer D connectors much beloved by other companies and not suitable for the under bonnet environment
- an off switch to bypass the module
- simple fitting with NO wiring modifications or battery connections.
- customer support provided by those who designed the product.

The tuning box uses our proprietary low power RISC microcontroller technology that digitises the sensor signal(s) 10,000 times per second, meaning that this is a truly digital module. Current consumption is negligible so no extra battery connections are required. Reliability is excellent with negligible failures and this is why we now offer a LIFETIME WARRANTY. The signal is then modified in the digital domain to reprogram the fuel pressure, overriding the engine ecu, to permit increased fuelling and therefore torque. This increase is in relation to driver demand and engine rpm so accurate control is possible more or less anywhere in the rev and load range. By incorporating 9 fuel modifying maps in the firmware, we can cleverly provide separate switches that control the torque enhancement at low/mid rprm (below about 2500rpm) and mid/high rpm (above about 2500rpm). Hence you can choose to have just more low down 'pulling power' - ideal for motorhomes and vans, or more 'top end' for sporty fast road use, or both for the power mad! The on/off switch allows you to bypass the unit and return the performance to standard. Switch it off for a few days now and again to remind yourself of just how effective the unit is!
