[f30_335i_ca]

Hi All,
appreciate any help here.
'04 M3 6M, car needs CA state ref from previous owner mods. I put exhaust & intake back however they said the ECU SW is modified.

With OBD scanner I read
Cal ID 1: 7842981,
Cal ID2: 7842980,
CVN1: C2 EF 8A 0A,
CVN2: 15C9 86 06.

I need to make these SW IDs back to factory, but not sure which binary to load.

I believe this correlates to MSS54HP, what binary do I need to load? From ECUWorx is it A7842980 – 211323002701J469.bin

Can I use WinKFP to reflash to stock?

TIA!
