New Bench and Boot solutions for Mazda and Subaru

Flex version 6.34.0.0 out now

New protocols have been released for Bench programming of E6T ECUs installed on Mazda vehicles and for Bench/Boot programming of CVT TCUs for Subaru models.

From now on you can elaborate engine parameters in Bench mode thanks to the E6T protocol, specifically for the ECU model.

Moreover, it is now possible to modify CVT TCUs produced from 2018 on in Bench mode, and TCUs from before 2018 in Boot mode.

The new 6.34.0.0 version of Flex introduces EEPROM memory reading and writing for Bosch T93 TCUs installed on General Motor vehicles.

Specifically, the following protocols have been added:

Mazda

Melco E6T6627x Bench
Melco E6TA157x Bench
Melco E6TA2771H Bench
Melco E6T67980H Bench

Subaru

Melco CVT Bench
Melco CVT (before 2018) Boot

With these new protocols it is now possible to read and write Flash and EEPROM memories (except for E6Ts with MH8501F processor, were the EEPROM writing is disabled).

Some of the supported vehicles:

Mazda 2 1.5L SkyActiv-G 75PS
Mazda CX-30 DM 2.0L SkyActive-G 180PS
Mazda CX-30 DM 2.5L SkyActive-G 250PS
Subaru Forester SK 2.5L 185PS
Subaru Impreza GT 2.0L 150PS
Subaru Levorg VM 2.0L 170PS

The new protocol is available for the following software packages:

FLS0.1M – SW Flex ECU (car, van, bike) OBD/Bench Master
FLS0.1S – SW Flex ECU (car, van, bike) OBD/Bench Slave
