Frieling Racing iBoot system is the ultimate in bench flashing tool for professional tuners who want to program ECU’s that cannot be flashed via the OBDII port. Using the Master Cable with purchased licenses, you can connect with a OBDII pinout and power connector. This male end tool has wires for power, ground, kline, Can High, Can Low, and others needed. To flash a ECU in boot mode, you need to have a boot pin on the ECU to get power. The iBoot does not supply these diagrams, however you can easily find these online.
