Until 08 they use a Lotus specific version of CAN that current OBD readers do not understand.I have a communication from Lotus in the UK confirming 2008.
I'm also not sure that pre '08 cars have any ODB-II type of data on the CANbus. Yes, the instruments are connected via CANbus, but if the need is for "performance data", it may simply not be there... But that's just a guess on my part...Until 08 they use a Lotus specific version of CAN that current OBD readers do not understand.
The ECU currently communicates to the gauge cluster via CAN.
Search posts from charliex, there is info out there on how to talk to Lotus CAN, but as far as I know, no off the shelf tools for it.
i don't quite understand, pennsylvania inspection requires plug into the OBD connector for a readout of some sort.
is that just that, that much of the installed software works but no realtime info is available on the (mine) 06 elise?
If you are looking for a reader you are probably better off not using the elm chip: you would need to build all the peripheral circuitry to get it to work and the chip doesnt support the 1K bitrate over CAN. A for the obd reader you can literally buy a iso9141 reader that will read the PIDs and convert them to rs232 or usb for about 100 bucks.If someone were to buy one of the Elm327 chipset readers (bluetooth) what sample rate would we get from the ISO9141 if we wanted to monitor 3-5 PIDS in real time on an 06 model year? Is 5hz possible? Is there an Elm based reader that can tap into the CAN side at 1mb/s?
