Alright, just a little update. Nothing good however. I have tried every setup that I have come across, and continued to read as to hopefully not miss anything that might help. Just to clear something up, I do not have the ms installed and it is not running anything at this point. I have made the connections and am still in the process of wiring a harness for the injectors. The issue that I am having is that I cannot find a tach signal that is both accurate and stable, it's either one or the other. After reading Corbin's post, I realized that he says that he only got tach spikes at a certain rpm range, and only after adding spark duties to the megasquirt. At this point, I must have done something wrong. Terry, in your experimentation with the ms2 v3 board, were you able to get it to run fuel successfully? That is all I am trying to do. It seems to me that I will need a stable tach signal nomatter what setup I run, but am I looking at this wrong. I have even tried to connect the ms wire to the white ecu tach wire, but the megatune rpm's seem to be about 1/2 of what the stock gauge reads. Anymore info you guys can give me will be very appreciated!
