i'm looking into buying a pc3 and wondering if this ecu will disable the immobilizer (my 2003 m620 is immobilized) and will it function without the gauge cluster?
*also does the powercommander replace the stock ecu?
The power commander is just a "middle man" between your ecm and injectors, so it shouldn't dissable your immobilizer, you'll have to fix that separately... It effectively piggybacks your stock ecm, interpreting pulse width signals and modifying them. It doesn't replace it, so it won't fix any underlying ecu problems...
thank you for clearing that up for me, i called a company called silverbackperformance.net and they will be able to disable the immobilizer which is much cheaper than spending 2,000-3,000 on new keys/cluster/ecu.
