SR3 Update: Bingo!

Phidget 8/8/8 card replacing the “road slug” 0/16/16 card. The 16 card requires a minimum of 16ms under the sensor to trigger. The 888 card only 4ms.

Just a quick update on the Pit-Entry limitations I warned about in my previous update.

I’ve been emailing a support guy at Phidgets in Canada, who has been very helpful. He came up with a couple of IR sensor config options for me to try on their faster 8/8/8 card. I couldn’t get this card to work in previous attempts so went back to their 0/16/16 card and decided to live with that card’s shortcomings.

The first and easiest option he proposed worked amazingly well.  A few of us will do some comprehensive testing on Saturday. But in my testing today, it seemed to detect every pit entry I could throw at it. And, to my surprise, it detected six cars entering the pits simultaneously. That indicates that the 8/8/8 card might just work for now on SR3–the 0/16/16 card had trouble detecting three simultaneous pit entries.

Anyway, time will tell, but it does appear that the pit-entry speed limitations on SR3 are removed, which is a good thing. No idea if it’ll support any conceivable “Hail Mary” drop into the pits, but I couldn’t perform an entry that it did not detect.

So, never mind my earlier update post. SR3 pit-entry speed limitations appear to be resolved.

Okay, shut up and drive!
