Thank you very much!

By the way, what does 0.75 mean or state for?

Thanks again,

Eventually I'd like to be able to switch units on the fly or at least select USA/Metric in the configuration and I've started coding in that style, but there wasn't enough program memory on my first attempt.

Updated June 12, 2009: it works on my 95 Neon Sport, 2.0L SOHC, 5MT - VSS/KM=9926, MICROSECONDS/LITRE=57442679.

I'm working on version 76m using the Atmel328 and Arduino IDE 0013 - plenty of space now - have already added RPM and working on L/KM.


Thanks everybody for this most excellent project. Being relatively new at Arduino, it is good to see more advanced code samples using interrupts/etc.
