Good day all
I know some of this might have been addressed elsewhere but here with some problems I haven't found answers to in the past 45 pages of topics:

1. Over-powered N1 during climb which results in EICAS errors "EPR Limit" and "FWD Equipment Overheat"; this continues into the cruise phase and the plane keeps flying at >100% N1 for no obvious reason even if I choose to cruise  at a low Mach (.74); TAT on EICAS going up and down (+30's to +40's) correspondent with crazy increments and decrements in N1 (I don't know which one is the cause and which is the effect)

2.Loss of lateral navigation (LNAV and HDG control) above 30000Ft; I know this has been discussed elsewhere but I also notice that the discussion wasn't really conclusive; for what's worth, I've disabled FSUIPC and re-installed the base-pack.

I'd appreciate any assistance.

Regards
Omid
