I did 2 sessions in the same 07 Porsche Turbo and got maps looking strange. The map on the bottom from another car is how Lime Rock should look. Both times I placed it on an aluminum cross brace below the rear window...it's possible the vibration or proximity to the motor did this???
Anyone seen this before???
1) Visibility to sky, maybe the installation location was not as good in that car, or maybe the windshield glass filters GPS signal.
2) Satellite situation due to weather etc.
3) High G-forces. Maybe can be improved by 1 and 2 points but could be it can't be totally avoided with this car.
But if the line goes to yellow or red, it's definitely dropping some of the satellite locks. Why that happens, I don't know. Poor visibility to sky or the weather? Could be interference too, I guess.
I now check the rc screen with the sat time to confirm it shows 5hz before the first run of the day.
As you know, to change it to 5hz, you must use their wanker software...which in my tests...if you set it to 5hz, then close and open it again it shows 1hz even though it is still in 5hz. You need to set it to 5hz. Quit the program and check in RC.
I still think these errors are caused by spurious emissions around electrical components.
So the post above only applies to 818EX.
If anyone has any info regarding the difference between the 2 models I would be interested as I can still exchange them.
