For autos that aren’t OBDII compliant, tuners really need to physically eliminate the ECU, open it up and solder a whole new microchip onto the motherboard, somewhat like upgrading an early nineties Personal computer.

Also referred to as chip tuning boxes, they get the job done by "tricking" the ECU into raising the quantity of fuel injected in to the cylinders, enabling a lift in force, for that reason leading to far more torque and electrical power. 

In case you leased your automobile, or bought a vehicle on finance, chances are you'll realize that remapping it can effect your deal.

When executing an ECU remap for By natural means aspirated engines, the increase in efficiency gained’t be substantial plenty of to justify the charges of car or truck tuning. In the meantime, turbocharged engines make important electrical power and torque gains.

Your vehicle’s motor might also be minimal somewhat to verify it may produce a great harmony of gasoline consumption and outright functionality in less-than-excellent disorders, like incredibly scorching climate (when engines commonly produce significantly less electric power.)

One more crucial factor that you ought to think about is the fact a remap can void the car’s warranty.
