A quick question regarding IAT. Hooking up my Nano an going through the various screens I see there are two showing IAT. One is under the Instruments page and the other under the GEMS ECU page.
The instrument page always shows the IAT to be somewhere around what you might expect to see (eg it was about 16 outside, engine running and the IAT was about 20, given the warmth of the engine bay, rising to 30 when engine off for a few minutes), whereas the ECU page always shows the IAT at very minimal levels (same day it was -2, which I can assure you it never gets to in Sydney).
I’m not concerned at this point as to the accuracy of the reading, but more the difference shown, using the Nano, which must (does it) get its base information from the IAT sensor. Anyone else get this sort of thing on this or other Nano menus?
I know the Nano is straight out wrong on certain sections (says mine is a 4.0 manual, whereas a proper test book shows 4.6 auto, nano shows UK police setting selected whereas test book shown non police) but I was interested in this difference. I’m off to send a note to the Nano guys and see if I get a response.
