Problem:

One customer gave feedback that AutoTuner Master Tuning Tool was unable to read SID209 via OBD. The software indicated that the ECU has already been unlocked using a different tool.

Key Information:

When an ECU is unlocked or patched by one tool, it often becomes incompatible with others.

Attempting to access it again with a different tool (like AutoTuner) – especially in boot mode – may cause ECU failure or a complete loss of communication.

Recommended Solution:

Do not attempt boot mode with AutoTuner, as this is high-risk.

AutoTuner released new software update for the Keihin KTKSv2 ECU on Triumph models via OBD on Sep 15, 2025.

Our virtual reading (VR) database is complete and covers all known part numbers, including 6001-19WN-000, 6001-19YH-000, and 6001-2933-000.

Note: This protocol requires the Motorcycle Euro5 OBD 6 Pin cable

Compatibility List*

AutoTuner released a new software update for the Continental GPEC4LM ECU in BOOT mode, found in Alfa Romeo, Fiat and Jeep vehicles on July 24th,2025.

This update adds support for a specific variant of this ECU, notably found on 1.5 engines. For those who followed the previous update, you may have already noticed these engines on the list!

BOOT unlock is also available for these variants, allowing them to be written via OBD mode. As this OBD protocol is in BETA, we invite users participating in the BETA program to report any issues they encounter so we can continue to improve it.

AutoTuner has updated the OBD protocol for Continental EMS2510, EMS2511, EMS2512 and EMS2513 ECUs installed in Ford vehicles.

Until now, only virtual reading (VR) was available for these ECUs. This operation has now been replaced with a real reading (NR) directly via the OBD port.

This ensures full compatibility, without depending on the availability of the file on our server.

Important note: previous virtual reads were 4MB in size, while the new real reads are 3MB. A new read is therefore required before any further operation on these ECUs.

Ogni tanto mi prende la nostalgia dei miei bei tempi e mi rifugio in queste cose.

Dice: anche ai tuoi tempi c'erano omicidi, violenza, rapine...

È vero, ma una differenza c'è, ed è grande e definitiva: "ai miei tempi" ancora sapevamo distinguere tra quello che era giusto e quello che era sbagliato, tra la verità e la menzogna, tra la bellezza e l'obbrobrio.
