Tracy. I wired my CAS the EC2 as instructed, but I also wired one of the leads in parallel with the hall sensor on my Rocky Mountain Engine Monitor. Does anyone think that this will not work? I'm not really sure how the hall sensor worked, but I figured the motion of the magnet created a small voltage spike in the circ. I figured the spike would be big enough to trigger 2 voltage sensors (one in the EC2 and one in the RMS Monitor) at the same time without causing any problem. This will be one of the things I look at if all does not work well at fist start, but does anyone know for sure this will not work? Thanks, David Leonard The Rotary Roster: http://members.aol.com/_ht_a/rotaryroster/index.html I bought 25 of these counters from Digi-Key and have a little extra board so I can make up a few more of them, so if anybody else is using the LS1 coils and needs to use a regular tach (Rusty?), let me know and you can have one for the price of a beer if we ever meet in person (if it's American beer, you'd better make it 2 beers :-). Good to hear that you got it working. I hope I won't have to take you up on your offer, though the price seems right. The meatheads at VDO tell me that my tach can't work with coil pulses, even though the instructions say it can, so it's destined to be a 100 yard target for my AR-15. Perhaps I'll send it back to VDO afterwards :-) I hope to get a lot done today, and tomorrow. The plan is to be completely finished, with the exception of the final inspection (shooting for the 16th), and successful tuning/testing of the engine. I should be able to run the engine again tomorrow, but only for the purpose of checking the tiny tach. I'll hope that Tracy can send the new firmware for the EC-2 by next weekend, so I can get serious about tuning and testing.
