Under this listing we offer preflashed 8HP45 and 8HP70, 8HP90 TCU control unit.
These units are used but tested genuine BOSCH controllers. They have been flashed with the latest MaxxECU 8HP v004 firmware.

Why you might need this?

The stock 8HP TCU is not able to communicate with MaxxECU's Mtune software therefore Maxxecu's firmware has to be flashed over the stock TCU. 

* Not all 8HP TCU is supported by Maxxecu. When you purchase a 8HP gearbox for your project you might have a TCU chip inside the gearbox that cannot be flashed with Maxxecu's firmware. They you end up with a gearbox that cannot be controlled due to an unflashable TCU.  If you are in this situation then we can help you.
* If you previously tried to flash your TCU but it failed and your TCU is bricked.

This is NOT an exchange & flashing service. We sell used & tested preflashed controllers that you can fit in your 8HP gearbox.
You place your order and we dispatch your Mtune ready 8HP TCU unit.
This 8HP TCU & controller will work ONLY with Mtune software & Maxxecu! It will not communicate with other third party ECUs!
