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 add a new constant which define the duty of the tach signal in the newest firmware? oscilloscope picture of tach signal [1000rpm 2ms/div] http://lh6.ggpht.com/_V2yrN18mN60/S_PS4XTBJeI/AAAAAAAAABQ/92vv6KwCRuQ/s640/1000rpm%202ms.JPG [1000rpm 10ms/div] http://lh6.ggpht.com/_V2yrN18mN60/S_PS4qSA1vI/AAAAAAAAABU/LK_cLQraTAA/s640/1000rpm%2010ms.JPG [3000rpm 2ms/div] http://lh3.ggpht.com/_V2yrN18mN60/S_PS5fHudxI/AAAAAAAAABY/3n4bFhhVjsE/s640/3000rpm%202ms.JPG
