Car has done 50k but I've only been running the MHD map for a few 1000 miles.

I'm looking at buying the Stage 2 map next week and then if all looks good on the logs I'll look into a custom MHD tune.

Need some dry weather, non stop rain in the UK.



The plugs were last changed at BMW 11k ago so I'll buy new NGK 94201 and close the gap to .022"

Which adaptations would I need to reset?
I've been running the 95_102 Stage 2 map with a 98RON/E30 blend for some time and it's good. 11.5@121mph and about 430 whp/480 hp engine.

Custom tune at E50, stock turbo, upgraded HPFP, best I've seen so far is 470 whp (SC_B5X)

You can try using Codes>Reset Adaptions in the MHD flasher.
It worth to try 102Ron map with 100Ron fuel? May be also to add octane booster
