Intake Air Temp reading 6°F too high. Is this a problem?

SouthArk370Z

I called my local Nissan dealer and was told that they would have to do an inspection/troubleshooting/&c and couldn't give me any kind of estimate of how much it might cost or if it would be covered by warranty. Went round and round with the rep. I asked "If we assume that the ECU is out of calibration by 6F, is that covered under warranty?". Got the same we'll-have-to-troubleshoot-it answer.

I swapped the MAFs and IAT is still 6F high.

I called the dealer back and talked with a different rep. Instead of going through the long explanation of what was wrong, I asked how much to recal IAT and is it warranty. This time I was told that re-cal was one hour labor (~$100 after taxes) and it should (but no guarantee) be covered under warranty.

I have an appointment for recal tomorrow morning. Even if I get stuck paying for it, it's worth $100 to me just to have the damn thing read right. Not so much for any performance benefit but just because I like my instrumentation to be right.

This should be a good time to get them to adjust the insolation sensor for turning on the headlights - been wanting to do that for several years now but didn't feel like paying $100 to do it.

Anything else I should have them tweak while they have it hooked up to CONSULT? It should take no more than 5 minutes each for the IAT and insolation - I'll still have 50 minutes that I'll have paid for.

Thanks for the help and support, people! I'm not sure which I like better, my Z or this site.
