Joel, for the tach signal, i'm tapped into the blue/white crank sensor wire at the ecu. I wired it that way for ease of installation, however do you think it would make a differnece if I tapped that wire at the sensor itself. On a side note, I had to replace the stock 95 crank sensor with a 97+ sensor. When I wired it in, I kept the layout of the wires the same. I shouldn't have assumed, but I thought the sensor would not function properly if it were installed wrong. Does anyone know if that is the case? It's interesting hearing you say that you couldn't get the car past 2200rpm. I thought that i've read successful posts about getting the v3 board to run fuel fine, but when you go to spark control, that is when the issues pop up. I do not have access to an o-scope. Again, thanks for the help.
