Thanks for posting that, but yea... I messed up with the way I used perfboard to attach the components on the vss/inj lead wires. It's pretty messy. Before, I was using 3-4 inches of wire LCD -> arduino. Now I may add more to clean it up near the arduino (where the problem was).
I'd pay to have someone build me a nice one.
I already have the appropriate wires tapped in my car (with crimp-on quick disconnects and everything).
