Guest xbangu Posted November 23, 2004 Share Posted November 23, 2004 Hi all, Does anone know what sensor/s does the AMF depend on when/ how much it open and close?? I am having trouble tuning my idle, it won't go below 1.5rpm at idling. Already test with good AFM, ECU and replace all holes on the manifold. thanks Quote Link to comment Share on other sites More sharing options...
Guest MaXbOOst Posted November 23, 2004 Share Posted November 23, 2004 i hate the AFM's . only way to lose em' is to go standalone with a map sensor.... but , i welded my flap on my AFM so its open all the time..... it has a air temp sensor on the inside of the meter , and the flap sends info back to the ecu. as far as i know , it doesnt open or close by itself Quote Link to comment Share on other sites More sharing options...

[/quote'] Um.. hmm.. you welded the flap open? And your car runs?!? also.. I'm sure a 300zx ecu/map sensor swap is do-able.. (if it's do-able for turbo z's..) and a HECK of a lot cheaper than standalone I believe.. Anyway.. back to the post topic.. The AFM IS the main sensor that the ecu reads from to run the engine. The flap inside has slight spring presure (pushing it closed) and is moved by the air flowing through it when the engine is running. NOW... If you've tested with another AFM and ECU, I'd say the problem is elsewhere.. not sure where to point you though... Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted November 24, 2004 Share Posted November 24, 2004 are you saying you can put in the 300z map sensor ? on any turbo L motor? how so ?? Quote Link to comment Share on other sites More sharing options...
datsunlover Posted November 24, 2004 Share Posted November 24, 2004 I believe there is a topic in the 'turbo/supercharger' forum.. near the top, it's been made a sticky. Quote Link to comment Share on other sites More sharing options...
