JR Handheld FLasher

JR Handheld Flasher is a device that reads and writes the software to a vehicle ECU via the OBDII port without having to bring the vehicle to our location - it is Remote Tuning option.

The flasher firmware and protocols can be updated via internet. It supports most of the cars, bikes, tractors and commercial vehicles.

You have to read the ECU and send us the original file - we will prepare and send back the file with requested tuning option.


The flasher can be used in many situations such as:

  • Your car still has a warranty – the ECU can be easily reprogrammed with the original software before visiting the dealer
  • The device can store multiply versions of the tuning options (custom, stage 1, stage 2, eco tuning etc.) It allows quickly change the tuning level by flashing the ECU in just a few minutes
  • Instead of ECU shipping option JR Flasher is cheaper and safer way of remote tuning (ECU can be lost or damaged in the shipping) - your car does not have to be locked in the garage waiting for ECU.
  • In the situation when small changes in the tuning are required it can be done immediately
  • JR Handheld Flasher can be used as basic diagnostic tool – it can read, clear the DTC’s - trouble codes from the ECU
Find your car in the Chiptuning Catalog to check if JR Handheld Flasher supports that vehicle.
