Never Mind - sorry, wrong forum, please delete - N55 135i - pulling timing on boost

Hi guys.

My car was eventually diagnosed to have a faulty boost pressure sensor (pressure converter). This has allowed the boost pressure and target in sync now and has sharpened up the car down low and given a more linear/consistent power delivery. Very happy.

On advice I enabled the timing correction logging in MHD and much to my disappointment I am pulling timing randomly across a few cylinders. The timing gets pulled it appears as boost develops. I recently changed plugs, ungapped bosch zr-whatever-33 model numbers.

I think it was pulling timing before the plugs replacement but maybe not as extreme.

Stage 1 on lower octane map, BMS charge pipe

Any obvious clues? I swapped one coil pack over but didn't get a change and petrol stations too. Also changed to higher octane stage 1.

Logs:

I believe post plugs: https://datazap.me/u/dainese01/log-1...data=3-4-13-23

Car is driving great and I'm stoked with it otherwise. Hoping to make sure it's running well, before Stage 2.

Greetings from Australia.

Justin

Probably would be best to post in the n55 section. These guys with the 1m are n54.
