RE: The discussion in this thread, According to Todd at Aeroforce, most CAN bus cars can update as fast as 20x per second. Which is probably why their Interceptor gauge displays boost in a R56 without any noticeable delay. So where did the "1 update per second rate" on the R56 come from? Anyone have tools to measure the data rate for OBDII gauges in a R56?
There is a big difference between what the CAN bus can communicate with and what it sends out thru the OBDII port. It is widely agreed to that the update speed thru the OBDII port is about 1 per second on the MINI. Here is a thread that explains a bit more about it. OBDII socket on an MCS 2004 - MINI2 - MINI Forum And there is this from UltraGauge Display Update rate?
Is the Aeroforce gauge the only OBDII device that seems to update faster than once per second in a Mini? Hard to believe no other products can. Todd at Aeroforce bascially just said you get what you pay for and they update quicker than once per second in a Mini.
I'd record a video of it displaying boost in time with the tach revving but I don't own anything that records video.
I just plugged in my scan tool (maxiscan ms509) and selected rpm - it was updating faster than I could read the numbers, so definitely more than once per second. The update frequency does slow down if you view multiple data simultaneously though. I'm not sure if that's limited by the car or the scan tool. Oh and that stupid p115C error is back again.:mad2:
Borrowed a flip video and recorded this today. Camera picked up a lot of glare but top is coolant temp and bottom is boost. Seems like its updating more than once per second.
