Tuning the diesel engine’s performance in the low to medium rev range also allows better power delivery for easier towing of caravans and/or trailers. Gain improved urban MPG by tuning the diesel engine's natural high torque output, allowing use of higher gears at much lower revs than as standard for better overall fuel economy. So, with the exception of 4 ECUs, 2 Simos, of which are old cars, Audi RS3 aren’t that common and that leaves PCR2.1 to unlock.Gets rid of those annoying flat acceleration spots in your Audi Q7 TDI and reduces the effect of diesel turbo lag for a more enjoyable and smoother drive, with longer performance power band. These require eeprom unlock on bench to allow OBD read/write/chk ME9/MED9 – ALL read/write/chk except rs3 MED9.1.5 reqs BDMĮxcept pcr2.1 and Simos 8.2/8.3. The CMD is able to read / virtual read / flash 99% of VAG group ECUs.

NO SEARCHING DATABASES FOR AN ORIGINAL FILE,įULL CORRECTION OF RSA AND ORIGINAL CHECKSUMS,ĬMD MASTER users also benefit from being able to flash VAS software updates via OBD direct from VAS DVD. NO RETURNING TO THE ORIGINAL TUNER FOR ORIGINAL FILE, This function can literally save hours of time messing around with a previously tuned ECU that requires a rework.
These are for ECUs that are unable to be read out via the OBD port but can be flashed OBD. The UDS protocols are VAG vehicles 2008+ starting with the B8 chassis. This button is available on the new VAG UDS protocols it restores the ECU Back to 100% stock. The CMD also has a few other features the Kess does not have.ġ00% BACK TO STOCK is now on both master and slave CMDs. This method takes time, involves risk to the vehicle removing anti-tamper bolts and also risk of ECU damage if care is not taken. If no original file available, the user must remove the ECU from the vehicle and carry out necessary bench work. The user must either request an original file from Alientech or ask their tune provider for an original file to work with. KESS can identify these controllers but is unable to provide the user with a file.

Most OBD flash tools on the market can offer the flashing of these later ECUs but none can offer the same functionality of the CMD.ĬMD can identify all VAG controllers including DSG (on CAN) and READ 99% of the ECUs via the OBD port or download a VIRTUAL read from CMDs server in less than 30 seconds without any ECU intervention (Bench unlock).

While boot loading is a good method, as the full ECU can be backed up in case of a problem, this method involves risk and takes up time.īoot loading would also be more suited to a workshop based outfit and not something that the lesser experienced mobile tuner would take on. Standard procedure for tuning later VAG ECUs such as EDC17 / MED17 has always been on the bench with an appropriate boot loader tool. The Flashtech CMD OBD tool is the perfect match for tuning VAG vehicles over the other common tuning tools such as the Alientech Kess V2.
