Does Motronic 1.1 ECU-s work with high impedance ECU-S? I am switching from 150-716 low impedance injectors to 150-203 high impedance ones. If I stay with the current wiring with fly wheel sensors, what ECU should I use?
Still debating switching to 1.3, but the damper mods and the fuse box mods needed scaring me!

Motronic 1.1 uses crank pulley sensor . the 1.0 type reference and speed sensors on the fly wheel, may not interface. Id do some searching to find out what this entails. Using them may restrict you to a 1.0 027 ECU which uses low impedance injectors I bet a super eta harness would make the graft as simple as possible. IIrc, 1.1 uses same impedance injectors as a 535 1.0
