MAF Specs

[wvicary]

Does anyone have the specs ( volts or grams/kg ) for the MAF sensor on a 2005 Cayenne V6? The only numbers I could find refer to a voltage reading of less then 1.1 volts at idle. I was looking for volume specs at idle,part throttle and WOT.

Anyone?

I looked and did not find anything other than ohm and voltage tests under troubleshooting P0102.

If you want those tests let me know...

Cheers Loren but I have those spec already. When I read the numbers using Durametric I got numbers I have never seen before. At idle it shows 180k/g and at WOT at redline 6100 k/g. I don't understand these numbers. I am familiar with grams/sec and have the specs for a Touareg V6 but they don't jive with what Durametric shows. I'll keep at it until I figure things out. Thanks for the help.

Usually (on other Porsches) from idle to 3000 RPM the number doubles or even quadruples.

I hope this info shows up on here. Please post if you find yourself. The only thing i'm digging up for this is kg/hour

I know audi MAFs (g/s) like the back of my hand but not much for porsches.

xsrfs, I know what you mean. The Vagcom software for Audi & VW's is ten times the product that Durametric is and it even costs less. The Durametric cable looks like a Vagcom copy but the software isn't up to Vagcom performance. Hopefully someday it will catch up.

Really? This is my first porsche and when I bought it I assumed there had to be vagcom equivalent. I'm shocked tbh. How do you diagnose these things then?

Durametric is about the only thing out there for a half way reasonable price. It is getting better with revisions but still has connectivity problems with the newer Beta version. It does cost more than VCDS and unless you want to pay a lot more for one of the higher versions, you can only use it on 5 cars as it locks in their VIN #'s.
