I have a problem with VEMS not seeing 2nd VR signal, hoping perhaps here would get faster reply.
All the info is here: http://www.vems.hu/wiki/index.php?page=MembersPage%2FPeepPaadam%2FPorscheNineFourFourTurboPnP
Tried switching polarity, nothing. Secondary VR assembled per instructions.
Do you guys have any idea?
TIA!
Did you add secondary lm?
Did you connect input to jp 20?

Is pin 13 on big connector disconnected(as should be)?
did you put 10 k resistor on second lm output? it needs to be near that secondary trigger bridge

in that black circle ;)
Thanks Kamuto, that was missing!
Regarding others, I did not state the obvious lol :D And in wiki link there is photos of my board, all the top side components are visible and ok.
I will test it right away!

it should work I think :D
Tested it with sound card, I used C130 since I don't have 3rd trigger and there is no special configuration in the Play Trigger menu for Porsche trigger. Even though it displayed 2x less rpm, there were no trigger errors etc.
On Friday I can test it on real 944 Turbo again, hope it will work fine :)
