No one answer on discord to my this question. I asked. The bmw m52 front mounted crank sensor is hall effect. I wired everything. When i want to start the car there is tooo much noise. By helping discord guys used 2 piece 2.5k pullup for crank sensor and see too much noise. Used noise filter car starts but rpm to the cluster not showing correct and the idle everytime at 2000-2500 rpm. I think there is pullup resistor not correct or something on wiring wrong.

Did a pin to pin from oem ecu(ms41.0) to the uaefi. I have some questions;
1. Do i need add or remove any resistor on this project ? I'll use oem crank hall effect and cam hall effect sensors, vag r8 coils.
2. Is possible to wire button for map switch? In my country the highest octane fuel is 98 lowest 92. For us for daily use 98 too expensive. I want to run 92 daily and when i want to race press button switch for example ignition maps to the 98 octane.

Can someone comfirm this pin to pin?
