Chip tuning or ECU remapping the engine in your Mitsubishi will allow you to enjoy a better overall driving experience. These two procedures are designed to make just the right adjustments to things like fueling, air intake, and ignition timing, so that the way your engine responds will be tailored to the particular environment in which you drive.
Chip tuning is the method used by our technicians to adjust Mitsubishi vehicles built before 2000. The procedure requires the removal of the Engine Control Unit (ECU) - a relatively simple procedure. Then the EPROM (erasable programmable read-only memory) chip is removed from the ECU and the generic data stored there in the factory is analyzed. (EPROM is a type of memory; it can retain information even when its supply of power is interrupted.) Mitsubishi, like all auto makers, uses generic values on the chips so that every vehicle, regardless of its destination, is shipped with the same information. By changing the data on the EPROM chip, you can enhance the performance of your Mitsubishi. And the changes will ensure that the engine provides optimal performance in your unique circumstances. Once the chip has been reprogrammed, it is reinstalled into the ECU, and the ECU is put back into your vehicle.
The remapping procedure is essentially the same as chip tuning, but with newer cars, there is no need to remove the ECU. Instead, the data in your Mitsubishi is read via an OBD/OBDII port and linked to the electronic on-board diagnostics in your vehicle. This procedure is used on Mitsubishis made after 2000, which have these diagnostic capabilities.
The performance gains are the same whether your Mitsubishi needs chip tuning or ECU remapping. The engine will deliver more power, and you'll notice improvements in fuel economy. All in all, your Mitsubishi will be more responsive, and your ride will be smoother after the procedures.
