# Team Product Owner @StefanSt Part of https://github.com/andreika-git/hellen-one family User documentation https://rusefi.com/s/hellen88bmw Inspired by https://github.com/rusefi/hw_88_bmw https://github.com/rusefi/hw_microRusEfi We shall start from https://github.com/rusefi/hellen121vag but using https://github.com/rusefi/hw_88_bmw shape and pinout. Plan: 1) merge https://github.com/rusefi/hellen121vag MCU stuff with shape of https://github.com/rusefi/hw_88_bmw from https://github.com/rusefi/hw_88_bmw we keep 1) outline 2) ignition coil drivers (we actually add two more - hw_88_bmw was a 6 cylinder board, we make a 8 cylinder ECU) 3) MAP sensor position 4) keep SD card somewhere 5) 88 jumpers
