Great project ! Looks fantastic, couple of questions/comments
For the pre-canbus cars (S1 and S2 prior to 08/09 depending which part of the world you're in) - are you taking a feed from the ODBII port to get the tell-tales (idiot lights) or does everything have to work of an analogue sensor of some kind? (I have an Aus delivered 07 Exige that is toyo engined, but pre canbus)
How do you manage data from the ABS for example? and RPM/Speed lag from the ODBII port? (if that's how you are getting the feed)
Also, re the track timer - I'd highly recommend putting in a GPS tracker rather than working off a beacon, no one generally (here at least) uses beacons any more. Or perhaps provide an interface to an external 10Hz Bluetooth GPS dongle?
Very interested in seeing this progress - well done
No OBD port, it works as the original cluster
S1 and S2 K series engine connects to the sensors direct (as did it original)
wheel speed sensor, rpm pulse from the ecu, fuel and temp are analogue,
ABS sends no data its simply got a warning light in the dash connected to the ABS module.
right about the GPS, a previous race dash I put together required a beacon input as that's what they used in their cars.
I carried this over and made it available in Elise dash
But a GPS module would remove the need for more hardware.
Also some cars have complete data logging functionality and in this case its the laptimer from the data logger which needs to be shown on screen.
So I have GPS on the list and integration with existing data loggers
...question? without a full list of race tracks stored in the memory of the dash how is the start point of the track calibrated by the GPS
do you simply push a button at a certain point of the track and use this co-ordinate from here on ?
or is it normal to enter the co-ordinates manually ?
I would always like to improve on any current method , especially if it not ideal
..and about the canbus are you sure your 07 is not Canbus ?
first toyo engined Elise had white face dials and canbus , the cluster had an extra connector for the canbus wires
08 elise with black face dials had everything in one plug
I expect your car to have dial face the same as my video , white with a tighter rpm indent for the first 3K
