About remapping

The L14 is one of the most widespread engine control units, fitted by many manufacturers. We have 84 remap files for the L14, present across 34 make and model combinations.

If you work with the L14 in your workshop, here's an at-a-glance view of which vehicles use it and which services (Stage 1/2, EGR, DPF, AdBlue…) are available. Every file is built from the original and is reversible.
