Just got off the phone with MSD. They were actually concerned, and assured me they'd do what it takes to get rid of my error codes. The guy's name was Philip. He concurred with me that he thinks the voltage going to the coil pack is dropping below acceptible range (from tapping into the system with the msd box), causing the error codes to occur. I guess that the ECU monitors this as it grounds each circuit to fire off the correct cylinder. I don't know. Anyway, he was most concerned about my tach adapters not working. Basically, a tach adapter is merely a signal amplifier....it doesn't alter the signal, but just merely boosts what is already there. He told me to check the lot number to make sure they were higher than a specific number, and then wire them into the system and test them again. If they don't work, then I'll send them back to MSD for new ones or for revised ones. He seemed pretty confident that we'd get it running properly, without any malfunction indicator codes. I'll keep you guys posted in case anyone else besides me is interested in getting more spark to their cylinders.
