CaM 0 Posted March 23, 2006 I heard a rumour that jetronic BMW's can replace their moving vane type AFM with a MAF/"hotwire" type from a certain model saab. anyone know if this is also do-able with the 205gti, as they run essentially the same injection system? chur, cam Share this post Link to post Share on other sites
M3Evo 0 Posted March 23, 2006 Not heard of any direct replacements, but lots of people have used some kind of piggyback thing to control a MAF. Share this post Link to post Share on other sites
Ryan 99 Posted March 23, 2006 Don't an AFM and MAF measure different things (airflow vs air mass)? If so then I don't think it could be just a simple plug-in replacement. Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted March 23, 2006 Yup, but Motronic may be able to use it. Jetronic certainly can not though. Share this post Link to post Share on other sites

CaM 0 Posted March 23, 2006 ok, 'tis a question of doing that and seeing how much improvement there is, or running an aftermarket ecu setup, which would be in the vicinity of $1500 NZ, installed and tuned. seems i'll have to go the latter to be rid of the moving vane afm Share this post Link to post Share on other sites
