Hey guys,
I'm going to be swapping this engine into a vehicle which cannot produce a VSS signal to the ECU, but which requires full OBD-II emissions testing.

Will this have any impact on the readiness state of the emissions monitors?  I'm thinking/worried that the monitors will never read "OK" since there may be a requirement for distance traveled as part of the checking process, and this information comes from the VSS signal via CANBUS.

I appreciate the help!

Thanks.
