As best I recall, In the programming world, its a mnemonic used to mean "No Operation"= NOP, in other words is was a line of code that used up a clock cycle(s) of the chip but actually did nothing. Sometimes used for timing purposes.

I think Tracy uses it to mean No Operation. The link between the EC2 and the EM2 is via three wires, two wires over which data and control pulses flow and the all important ground wire. If do not have a good electrical ground between your EM2 and EC2 the serial communication function will not operate properly or may be sporadic. Since you have power to your EM2, I would check and see that it has a good ground to the EC2.

Subject: [FlyRotary] EM2 NOP flashing w/RPM and a couple of other questions

Ok, the engine IS running and seems to be running better each time. I want to do the autotune process, however, even tough the engine is running, the EM2 is flashing between NOP and the engine RPM. It flashes between the two while the engine runs. What is this telling me? What does NOP stand for anyway. I must keep reading over it in the manuals. Also, when I start the autotune process, NOP is displayed on the program screen.

Also, I have misplaced my books from Tracy (the Rotary Coversion Guide & the Mazda Papers). Could y'all point me to a link and/or provide some basic engine parameter guidlines such as what is the desired oil temp and water temp, preferred idle speed etc? My oil temp seems to be holding around 190 F and my water was going up past 210. I added an electric fan over the heat exchanger/radiator which help it get there slower. Now, to be fair to my system, this was on a very hot ramp, in a 100 degree Houston summer in bright sun. A bit later it clouded up and the temp went up much slower and was holding at about 190 to 200 ish before I shut down to do other stuff.....well, actually, go home and eat the steak Jana made for me <g>.

Thanks for the time and consideration. Y'all are making this process MUCH more doable.

All the best,

Chris
