Engine temp and Air mass readings from INPA



Air mass reading seems off the scale? any ideas read on the google could be MAP or MAF

Also engine temps show as over 100deg in INPA but the hidden menus only show 69deg? which do i believe?

i did have it all hooked up from a cold start and the coolant temp climbed up to that point and didnt seem to be stopping. so i checked the onboard read out.
I have read that the eariler version of INPA can give false readings so im going to try update it and go from there.

Yep, got new EGR and main thermostats to go in to hopefully solve that. temp barely gets above 55deg on my usual commute.

I got the package from Cable shack. so just used their install UI the first time i installed i just did it manually.

It may not be 100% up-to-date with regard to Daten files but the INPA version is the latest

Interesting, my 330d was showing the same with air mass reading being off the scale, was the same with it unplugged, which it shouldn't be, so I need to check what version of INPA I've got and update it.

Me too. I have a 730d and my Maf is off scale plugged or unplugged. But I get that even in Ista+.
So how to blame? Software or maf??
