Edit: I've decided to not offer ECU flashes due to updated guidance from the EPA on tampering policy.Last edited by Andrew325is; 07-18-2021, 01:31 PM.

Originally posted by Andrew325is View PostI've decided to offer ECU flashes without the purchase of a harness for the S54, S62, and M54 with an MSS54, MSS54HP, MSS52, or MS43 ECU. No other engines or ECUs are supported at this time.
Available options for all ECUs:
-EWS delete
-SAP disable (DTCs disable)
-Rear O2 sensor disable (DTCs disabled)
-Speed limiter removal
Additional options for S54 (MSS54 or MSS54HP) and S62 (MSS52).
-Disable Cat efficiency DTCs
-Disable SAP/Cat heating sequence
-Change rev limit (all gears + N)
-Change dyno rev limit
-Change between SMG or manual transmission
-Change SMG final drive ratio
-IAT sensor re-scale
-Change cat protection threshold temperature (S54 only)
-Change sport memory settings
-Burble / pop on lift off (S54 only)
-Disable CSL intake flap DTCs (S54 only)
-MAF delete / Alpha N (S54 only)
-Disable cat protection (disables enrichment) (S54 only)
-Disable EGT monitoring (S54 only)
-Disable ‘105’ DTC for motorsport thermostat (S54 only)
-SMG shift lights for 6MT
Some options may not be available depending on ECU version. There aren’t as many options available for the S62 as there are for the S54. I won’t know until I load the file.
I’m also able to apply an Evolve Automotive Performance Tune for S54. Gains are between 14 and 18 hp (above 5000 rpm). It is available for both Euro and US cars with either US or Euro headers. High octane fuel required (98 for Euro tune or 93 for US tune).
Prices:
$100 for ECU flash with any of the available options
$400 for Evolve Automotive Performance Tune for S54
Most of the price is to cover the licensing costs of using the flash/tuning software. I’m offering these services as a benefit to the community.
