Big question. Combine with knock shield and datalog?

How difficult would it be to combine the lambda shield with knock shield and add an RPM input for datalog purposes?

Without dyno access this would be ideal for road tuning

Unfortunately there is too many pins that would have to be relocated, it is not impossible but quite difficult. You can however connect multiple Arduinos to your PC.
