Hi, I've upgraded my MX5 cable driven speedo to a BMW ZF 6spd which doesn't have a speedo. I'm trying to adopt a later model MX5 ABS sensor to grab a digital reading and then convert that to cable for my speedo in the dash. My question is, does the ECU have some kind of speed reading that I could tap into and bypass the ABS sensor/converter box altogether? If so I could then get a CAN display and use that as my dash.
