INTRODUCING TO ECU Remapping, WHAT IS THE ENGINE CONTROL UNIT?

Before the ECU Remapping, we have to say that the ECU or Engine Control Unit is an electronic device that manages all engine parameters. Most of the units are produced by Bosch, Magneti Marelli, Siemens, Delphi, and Delco IAW.

On WHAT VEHICLES can WE MAKE THE ECU REMAPPING?

The units were introduced in vehicles around 1990, but until 2000 were utilized memories that could not be erased and reprogrammed. It was necessary to dismantle the unit and replace the memories. In the following years were introduced reprogrammable memories that have facilitated the work of re-mapping, allowing the programming via special tools. Those can read the original software of the vehicle and copy it to a computer without disassembling the unit. With the same procedure you can write the new software. The changes are instantaneous and in case of errors you can permanently block the functioning of the unit or damage the engine.OBD Connector

WHICH PARAMETERS WILL BE CHANGED AFTER THE ECU REMAPPING?

The main parameters that are modified are the injection time, the pressure of the fuel pump, ignition timing, the sensitivity of the accelerator pedal. Sometimes also the limits of the lambda probe, the turbo pressure, overboosts time, the command of the throttle and the rev limiter.Chip Tuning Winols,ECU Remapping

WHY CHANGE THE ORIGINAL SOFTWARE?

The manufacturers produce vehicles to be marketed in different countries, with different limits on pollution, fuel, weather conditions, driving style and routes. To reduce costs in the design phase, the automakers produce a single engine that will be adjusted (and limited) by programming the control unit depending on the country where it will be marketed. Always leaving a margin of tolerance to not make the maximum capabilities of the engine. With the change of the control unit you can make gains in terms of power and consumption, reusing the tolerance margin left by the builders and adapting the software to the precise use of the client. Nowadays there are many vehicles on the market with the same displacement but with different powers, this well be a commercial gimmick to boost sales of the new models. It is a practical example of how the software of the control unit can increase or decrease the return of a motor. If the adjustment of the control unit is made with criterion, one can obtain increases in power and torque up to 25%, reducing fuel consumption up to 20% with increase of the duration of engine life.chip-tuning

AFTER THE CHANGE, CAN YOU RESTORE THE ORIGINAL PROGRAM?

The moment you make the change of ECU, the original software is copied into our database and delivered to the customer. The customer can use it again at any time to restore the unit to its default settings.Backup ECU

WHAT DEFECTS CAN BE CORRECTED WITH THE ECU REMAPPING?

  • The car has covered many kilometers, and is not as efficient as when it was new?
  • With the passage of time have you noticed an increase in consumption and a decrease in performance?
  • The turbo starts working late and does not push as it should?
  • Starting the engine comes out white smoke from the exhaust?
  • The car takes too long in making a pass?
  • The car has problems with the climbs?
  • Il pedale acceleratore è poco sensibile?
  • The accelerator pedal is not very sensitive?
  • Are cautioned holes or irregularities during acceleration?
  • You clogging problems with the diesel particulate filter?
  • The engine will not start easily in cold or hot?
  • The automatic transmission creates problems when you’re climbing causing continuous gear changes?
  • You have problems with the EGR valve?
  • You have installed a sports exhaust without catalytic converter and want to eliminate errors relating to Lambda sensors?
  • Do you have a van with AdBlue system and want to reduce costs by eliminating the additive?
  • Have you noticed an increase in oil during the oil change?
  • You have a vehicle racing and want to eliminate the speed limiter?
  • You have mounted a turbo increased or increased injectors?
  • Want to exclude the operation of the flow meter?
  • Want to exclude the Start & Stop system?
