Gibot123 16 Report post Posted October 31, 2013 Does anyone know if it's possible to rewire an old style air flow meter to run a maf style sensor. Or is there more to it than just the sensor message to the ecu. Does the air flow meter actually control the idle air at the meter it's self or is it all done at the ecu or is that only on the electronic throttle body's and not the cable controlled ones ?

alfizta 6 Report post Posted October 31, 2013 I guess that an Air Flow Meter does not have an integrated temp sensor as the the MAF has, right? Quote Share this post Link to post Share on other sites
Gibot123 16 Report post Posted November 1, 2013 I'm not sure what exactly does what . Just very curious to find out. I think that the earlier AFM tell the peramiters of the air intake to the ecu but it also has an electronic box that seems to open and close the main air flow before it gets to the main throttle body on the AFM itself. I think this has been overtaken by the fly by wire system but I really don't understand properly . Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted November 5, 2013 Because the old Air flow meters used rheostats, new ones use thermocouples, completely different signals. Quote Share this post Link to post Share on other sites
