By chip tuning or remapping your Renault engine, you will enjoy better overall driving performance due to appropriate adjustments made to ignition timing, fueling, air intake, and other factors. These can be tailored to your unique driving environment and style.
Chip tuning is used on vehicles manufactured before 2000. It requires our technicians to remove the Engine Control Unit (ECU) from the Renault, which is a relatively simple procedure. Then they remove the EPROM (erasable programmable read-only memory) chip from the unit to read the generic data stored there by the manufacturer. EPROM is the type of memory that retains information even if its power supply is turned off. Renault factories, like all auto makers, use generic values on these chips that are same regardless of where or how a vehicle will be driven. You can get higher performance by having the data on the chip altered to fit your circumstances. Once the chip has been reprogrammed with the appropriate values, it is reinstalled into the ECU, and the ECU is put back into your vehicle.
Remapping is essentially the same as chip tuning; only there is no need to remove the ECU from the Renault because the stored data is read via an OBD/OBDII port and is linked to the electronic on-board diagnostics in your Renault. This procedure is used on vehicles made after 2000, which offer these diagnostic capabilities.
The performance gains are the same whether you apply chip tuning of ECU remapping. You will have a more powerful drive, better fuel economy, and a more responsive throttle in your Renault after either procedure.
