Tachometer problem:

Orginal tachometer has a dutycycle of 33/256 and dont like signals other than that. I run the old open source-code (r027) and I made a sucessful change in it to make it work. but I will upgrade to newest firmware soon..

Is it possible to make a new constant which define the duty of the tach signal in the firmware?
