Right so i had some issues with rev 1;
- not triggering some remotes (too fast)
- no power option for the remotes
So i give you rev 2
- Variable voltage for the keyfob (1.25 - 12v)
- User variable trigger time (0.1 - 2.1s switch time)
- General tidy
Note this will not fit in the same place as rev 1 (unfortunately) however can still fit into the xAC housing if you want (without modification) however i envision a sort of Y-harness between the xAC and this box the simplify installs.
Please please please review add comments and ask questions!
I am still working on a complete car / motorcycle / whatever implant entry and start system the idea if for it to work with any id you can put onto a 5577 chip (please dont hold your breath just yet 
)
