Karman Vortex to Hotwire MAF
Hello All,
Having seen some of the posts regarding the Karman Vortex MAF meter on our beloved Evo8s, I think I now understand the system and how it works.
Last weekend I took apart my intake box just to see the KV unit, and yes, it certainly looks like a restriction.
Shiv discussed awhile ago that the XEDE could be tweeked to produce a MAF waveform using a MAP sensor and temp. sensor, BUT a MAP installation seems a little 'much' for my shadetree mechanic skills.
I've had this thought in the back of my head about doing a Hotwire system.
Would the benefits really be there, in using a hotwire to open up / smooth out the intake? I know BMWs use a lot of hotwire systems. How reliable are they? What type of calibration, if any, is needed?
Thanks,
jcnel.
