I noticed when doing a online race. When driving away the pitlimiter kicks in quite late. So a car (Cadillac DPi) tends to go up to 64 km and than drops to a steady 60. Just enough to receive a speeding in pitlane penalty. When serving the penalty I immidiatly got a new one. Would it not be better to have a bit of headroom, that you need to go faster than a few km for more than half a second before you get awarded with a penalty. Or that the pitlimiter does it's work a bit better. So i cuts of at 55 and than goes up to 59.5. Instead of cutting at 64 and bringing it down to exactly 60 Just my 2 cents.
What gear were you in? You need to be in first gear for the pit limiter to work correctly, from what I understand.
This is car and event specific. By which I mean, the car determines how the speed limiter will come into effect (tbh I'm not sure what characteristics of the engine will influence this - I don't think there are limit-specific settings, and I've personally never seen such a speed variation with the limiter engaged). And, the event (.rfm file) has a parameter PitSpeedingAllowance that allows for some leeway on speed limits. If cars being used have some 'natural' variations, this should probably be increased to compensate. @Bill Worrel those pesky characteristics aside, the gear shouldn't matter. I have found that changing gear on/near the pit limit speed can bump you over, but not as much as 4kph in cars I've used. (disclaimer: I don't have the Cadillac)
I just know that I got a speeding penalty when I was driving down pit lane in a higher gear (to save fuel) and was told by others that you have to be in first gear. But this was not in an official car and I didn't know it's a car specific issue.
I've seen a lot of cars in rF2 that the speed of the pit limiter depends on the gear that you are. For example if the pit limit speed is 80 km/h, activating the pit limit: In first gear you go to 79km/h In second gear you go to 79km/h In third gear you go to 82 km/h In fourth gear you go to 84 km/h In fifth gear you go to 86 km/h Etc. I've seen this in official cars too (FISI, for example)
The issue is that the limiter wants you to run an rpm that would stall the car(if you're in a high gear), so it just doesn't work.
