JEEP Wrangler ECU remapping
196 files available
About remapping
The Jeep Wrangler accounts for 196 files in our catalogue, with the 2.8 CRD as the dominant engine across its various designations, followed at a distance by the 2.2 diesel of more recent versions. It is a serious off-roader, and the kind of map it calls for has more to do with available torque than with top speed.
Stage 1 accounts for 137 files of the total. On a vehicle with this aerodynamic profile and these gear ratios, what is wanted is pull from low down so the engine does not have to be worked hard in difficult terrain or with a trailer. The most common ECUs are the EDC17CP27 and EDC17C69, plus the EDC16CP31 on earlier units.

What does a Wrangler 2.8 CRD gain from Stage 1?
Mainly torque at low and mid revs. On a vehicle with this weight and aerodynamic profile, that translates into less need to change down on climbs, with a trailer or off the tarmac.
Does it affect off-road use?
A well-judged map preserves throttle progressiveness, which is key in technical driving. It matters that the file does not chase peak figures alone but a usable delivery.
Do you cover the more modern 2.2 diesel?
Yes, although the bulk of the catalogue corresponds to the 2.8 CRD. Send us the reference of your ECU and we will confirm availability for your specific unit.
