Remapping your ECU

28 July 2011 5 Comments

Using sophisticated software, your car instantly becomes more drivable just by tuning the maps on your cars ECU. This means you don’t have to change any of the hardware on your car because the software just remaps the car through the OBD/II port. This is a whole different process to chipping  in that remapping the car does not involve opening the actual Engine Control Unit, but instead, separates remapping software which links to the cars ECU. The original maps are downloaded from your ECU and then replaced with a more optimal remapping which is then uploaded back to the ECU. The process usually takes 30-45 minutes.

Which cars can be remapped?
Most makes and models of cars these days can be remapped, with Diesel and Turbo Diesel models giving the best performance increases, both in the Torque and KW. This gives the car much better response than the usual factory settings. Basically this mean that after the remap your car will perform much better than it originally did. This includes having more power and an increase in fuel efficiency. Manufacturers are by law required to add a dip to the power map on your engine between 2k and 3k RPM. This was originally meant to increase fuel consumption to make more money off motorists for the fuel companies (sneaky shit right)! One of the many processes involved in remapping a car involves removing this power dip, making for a smoother power graph as you go through the gears. The smoother graph means you actually have to change gears less often which in turn  increases fuel efficiency.

After doing some research on this “manufactures dip”, I found out that many manufacturers also actively limit their car’s performance, usually so they can release a ‘sportier’ version of the same car at a later date. The only difference between the standard edition and the sport edition (other than a few body kits or what have you), is generally the maps stored on the ECU. Through remapping the car, this limitation can be removed, essentially making your car perform exactly like the sport edition! After finding this out I’ve recommended all my mates to get their cars remapped.
