Flash MS41.3

Minimum Requirements :
1. MS41 QuickFlash must be installed because the base MS41.3 code is sent in a proprietary encrypted format which only MS41 QuickFlash can upload to the ECU/DME.
2. OBD2 USB Cable with FTDI FT232 chip because it is more reliable and supported by MS41 QuickFlash.

4. Check the MAF Scaling and Load axis for the Fuel/Timing maps to ensure they are correct. Especially, if you used to run with 'hacked' MAF/Load.

*You will not be able to use any flashing software to read the full 256KB.bin or 257KB.enc

*You will be able to read/write the 24KB. All tuning can be accomplished with 24KB now :)

1. Write to ECU 257KB .enc file with QuickFlash v2+

2. Tune in RR 24KB and Save

3. Write to ECU 24KB

*** ONLY FLASH THIS 24KB TO THE ECU ***

*** DO NOT FLASH YOUR OLD 24KB ***

If you need to revert back to the stock code, reflash your full 256KB file you sent me previously.
