If you are modifying your diesel engine, chances are your standard MAP (manifold absolute pressure) sensor will need upgrading. Some manufacturers fit sensors that are even sub par for the standard turbocharger. This is where we come in to help.

These 4 bar sensors, will happily see you towards your goal of achieving more power, in a safe and reliable way. Not only do they measure the boost pressure to help with the tuning of the turbocharger, and ensure the ECU can adjust the turbochargers output to match that which the software on the ECU is asking for, they also add a margin of safety, because running at 1.9 bar of boost (2.9 bar actual) on a 3 bar sensor, there’s little room for the ECU to monitor large spikes in overboost.

No one wants to see their brand new and expensive hybrid turbocharger, dismantle itself into the engine, because the ECU was unable to register an issue.

Sensors available with correct loom adapter to quickly and easily wire in the sensor to your current engine loom. Calibration data and wiring information included.

One sensor, or one sensor with plug as selected.
