Installed S15A-24-03-547_4.0.1 in my 24 X4M using licensed ISTA and an OEM ICOM.

I have no good reason for doing this other than my obsession with software updates and hyper focus on seeing a project through from start to finish.

Overall much easier than I thought it would be. Took about 45 minutes including the power supply setup and initial ISTA tests / calculation.

I also wanted to point out that I have been playing with official ISTA since ~February of this year and it has not once flagged my car for tuning. It does run the tuning detection tests, but always passes. This is with a Dahler module set to Race almost every time I am out for roughly 12k miles.
