I will do a re flash, add some more E and then do another run. I'm located in Sweden, and our fuel is known to be bad. But that doesn't really explain why my stage 1 tune with less E runs better. Maybe higher boost/lower timings. I'm thankful for any other suggestions. |

Yeah as you say, flash stock, use stock gap, check for any fault codes, and do a log while stock. Start from there

MHD Stage 2 HPFP Logs & Dyno Chart
So I had a couple of runs on one of the UK's most conservative dynos at the weekend. First run was MHD Stage 2 HPFP 95 Ron; second run was MHD Stage 2 HPFP 98 Ron. Tesco Momentum 99 Ron fuel was used in both runs and with no ethanol. Only hardware modifications were a 4.5" 200 cell downpipe and TU HPFP.
See both logs below and accompanying chart. Hopefully this might be useful but comments would be welcomed! Note how things seem to plataeu a little early on the 98 Ron map, around 5200rpm? I'm undecided if I should just run the 95 Ron map in the longer term or add ethanol on the 98 Ron. This car is my daily driver and I'm not sure if I want to be adding an extra £15 per tank when the benefit isn't actually that much? There was an M140i there too with the exact same MHD map, same fuel, same TU HPFP but had a 4.5" decat, rather than 200 cell. His peak power was 456 bhp. His graph looked identical to mine in every way. I have seen his logs too and they are very similar, albeit with slightly worse timing corrections. Dyno chart is flywheel figures. https://datazap.me/u/simonocr/2024-0...og=0&data=3-17 https://datazap.me/u/simonocr/2024-0...0&data=3-17-43 Last edited by SimonO; 05-19-2024 at 06:15 PM.. |

I have now reflashed stage 2. This time BM3 asked me to download stage 1 map before flashing, which didn't happen before. I also set all the settings to OEM or otherwise without leaving them on "choose".
The log looks a bit better, but I think the power is still down. Do I have to high expectaions or are the timings actually low? https://www.bootmod3.net/log?id=664a...2aed60cedf4296 |
