If I set my Zumo660 to simulator mode and then let it simulate a ride I see wrong speeds simulated at times. The speeds based on road_speed tags work fine. When simulating riding on a road with a speedlimit=90 tag the gauge on the GPS says 100 and when on a road with speedlimit=50 the GPS shows 60. Any ideas of what is wrong?

I don't understand what you mean by this sentence.
When simulating riding on a road with a speedlimit=90 tag the gauge on the GPS says 100 and when on a road with speedlimit=50 the GPS shows 60.
I am fuzzy, but my understanding is that there are several (8?) road classifications, each with a defined speed, hard-coded into the definition of the img format. Speeds are mapped to the closest/rounded/truncated or something. Usually this is good enough for routing.
If I simulate a ride on a road with road_speed=4 and speedlimit is not present the speed will be 90km/h, this is correct as I see it. If speedlimit is set to 90, the simulated speed will be 100km/h. This is not a big problem but I suppose the calculated arrival time will be a little wrong.
