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: before plugs: https://datazap.me/u/dainese01/log-1...20-21-22-24-25 I believe post plugs: https://datazap.me/u/dainese01/log-1...data=3-4-13-23 https://datazap.me/u/dainese01/log-1...data=3-4-13-23 https://datazap.me/u/dainese01/log-1...data=3-4-13-24 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 Last edited by dainese; 11-29-2018 at 07:22 PM.. Reason: Never Mind - sorry, wrong forum, please delete |
