Air Pump Simulator for 2 Bank all 6 Cylinders I have created a air pump simulator for all 6 cylinder BMW engines with 2 upstream O2 sensors. It is the same size as the M44 unit but controls both bank 1 & 2 for a 6 cylinder engine. I'm shipping one off today for testing and will post pictures and wiring diagrams when I get some time later this week. Just an FYI. ***This is to be used for test purposes or on track cars only*** | Tutorial Tools | | | | |
