What is remapping?
When a manufacturer develops a new car, truck, bus or machinery they have to take into consideration all of the conditions it may be subjected to in all of the regions/countries in which they intend to sell this model. This means that instead of optimising the Engine Control Unit's (ECU) program or 'map' solely for the best performance or the most fuel efficiency, manufacturers must compromise the map to account for these potential differing operating conditions. When we remap a vehicle, we change the parameters inside the factory ECU to best suit how you use the vehicle. The maps that we adjust may include fuel pressure, boost pressure (on turbocharged applications), ignition advance and throttle pedal control among others.
See Remapping & Dyno TunesIs remapping safe?
Yes, it is a completely safe process as it gives the engine the performance it would have had in the first place before the compromises were applied to the original programming. We do not remove any safeguards and all of our tuning is done on our Mainline dyno to ensure that the remapping is kept inside safe limits.
See Remapping & Dyno TunesHow much does remapping cost?
Remapping on our Mainline dyno starts from $1,350, depending on your vehicle and the outcome you are looking for. Mechanical pump tuning starts from $750. Contact us with your vehicle details for a quote.
See Remapping & Dyno TunesHow does the dyno process work?
We begin with a baseline dyno run, adjust the relevant engine settings, and use further runs to assess the result — then compare the final tune against the baseline.
See Remapping & Dyno TunesDoes tuning affect my warranty?
Warranty implications vary. We'll discuss this honestly before any work — we won't make claims we can't stand behind.
