JAC Remapping Service
JAC makes pick-ups, vans and SUVs that do a hard day's work, and a remap can take the strain off the engine when they're loaded. We write each map in-house for your engine, so it suits how you use the vehicle.

Why Remap Your JAC?
On a pick-up or van that works for a living, the gains that count are torque low down for pulling, smoother progress in traffic and a bit less diesel each week. For working vehicles our commercial van remapping is built around that, and an economy remap puts fuel first.
JAC Diesel and Petrol Tuning
JAC isn't in the vehicle catalogue our calculator reads, so choose JAC in the calculator and enter your model and engine yourself. We look at the engine and come back to you with what a remap can do for it. The map is written in-house by a qualified motorsport engineer around the loads you carry, and the vehicle goes on our 4WD dyno before and after. JAC SUVs are covered by our car remapping too.
Call us on 087 744 2633 with the model and engine, and we'll take it from there.

What happens on the day
Check your JAC in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.
If your JAC is an automatic, ask us about a gearbox (TCU) remap on the same visit.
