MSII v3 with ignition enabled and using a VR sensor. I have used this setup for all my races with no problems. Went Laguna Seca this weekend and no spark. I went through all the usual tests (checking grounds, signals at all the points on the relay board, checking for current at all the usual places) but no spark. I have a perfect connection between my coil negative and the relay board, a good voltage signal from the VR sensor to the relay board. It ran perfectly a couple of days ago but when I got to the track, no spark. The coil is good, the voltage to the coil is correct. I switched my MSII with my spare unit and burned the proper msq to it. I changed the relay board with my spare, all to no avail. Interestingly enough, I have a signal on my tach when cranking but no signal on the Megatune display or Tunerstudio display on my laptop. I get a MAP reading and other readings on Megatune and Tunerstudio but no tach signal or tach count. Something simple is missing here.
Any ideas anyone?
Thanks,
James

Re: No spark
Ok, the only thing that got changed was the battery got moved to the rear of the car. There must be too much voltage drop to run the MSII. I will run voltage drop tests tomorrow. Does anyone have other suggestions?
