Okay guys im totally stumped. The car is a stock 1977 280z with a n47/n42 and stock distributor. I am attempting to megasquirt it v3.0 board msns-e 029y4. I cant get the vr sensor to read rpms or better yet i cant get tuner studio to see rpm while im cranking. I built this board myself, everything looks good. Both trim pots are 18+ turns ccw. Ive wired the vr sensor backwards nothing. The only way to get that rpm gauge to move is to short the sensor and tap the connector together. I dont own a scope but i do have a multimeter. I dont have a stimulator but theres one in the mail, It will be here soon. I have no idea whats going wrong, As far as i know it should be triggering. Please help. pictures of the board are attached. thanks
