For the E-mix verification, I use the FuelIt app. My car runs well and has no issues whatsoever. |

For the BMW G-series JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select WMI page option 2/3/4 input to enable.
this is what they said on their official website So I'm confused, because everyone has different settings! can anyone help me explain the purpose of each option? |

I suggest you reach out to BMS for the correct settings.

Can anyone talk to the tuning process? Do tuners like F80 Paul just start with a standard tune or is there more of a discussion?

You will get a base map that is more aggressive than off-the-shelf maps. After looking at your logs they will keep fine-tuning it until you reach your goal or they reach their safety limit.

I finally was able get an e85 reading in my JB4… but reads 4% lower than the Fuel-It App (Fuel-It reads 9% while JB4 reads 5%). Is everybody having the same issue?

Logging pulls on the street is actually best from a load perspective compared to a standard dynojet. In previous cars I’ve owned they’ve always run a bit leaner on the street versus the dyno and sometimes would need a little less timing as well.
