After my recent firmware upgrade I no longer have any reading on the VSS (Vehicle Speed) channel?  Does anyone else have this problem?

My speedo still works so the sensor is still working.

Car is a 2001 Honda S2000.

Same here, except on a 1994 toyota supra automatic. Speedo works, but VSS input to AEM reads nothing. Since an automatic needs VSS to shift, the car can't shift. Reverted back to v1.17 but now we find issues with using INJ7 and INJ8 as general outputs (can't set up to provide low output) which were not present in v1.23. Arrggh!

Does AEM ever respond with an indication they will address a bug in the next version, especially if it breaks every car out there with an automatic...

It would be nice if AEM took a more active role in their forum but I wouldn't hold your breath.
