I've got a problem getting spark to work. Megatune isn't reading any rpm's and only the centre led (ms V3) illuminates when the unit is powered up. I'm trying to run 2 vr conditioners so I don't butcher my cas. Im using errors daughter board, however it didn't come with instructions on how to connect. Where have I gone wrong? By the way the cas G- is connected to ground and the Cas G+ is soldered directly to the 12th pin of the LM1815 chip.
