As best I recall, In the programming world, its = a mnemonic=20 used to mean "No Operation"=3D NOP, in other words is was a line of code = that used=20 up a clock cycle(s) of the chip but actually did nothing. = Sometimes used=20 for timing purposes.

I think Tracy uses it to mean No = Operation. =20 The link between the EC2 and the EM2 is via three wires, two wires over = which=20 data and control pulses flow and the all important ground wire. If = do not=20 have a good electrical ground between your EM2 and EC2 the serial = communication=20 function will not operate properly or may be sporadic. Since you = have=20 power to your EM2, I would check and see that it has a good ground to = the=20 EC2.

Subject: [FlyRotary] EM2 NOP = flashing=20 w/RPM and a couple of other questions

Ok, the engine IS running and seems = to be running=20 better each time. I want to do the autotune process, however, = even tough=20 the engine is running, the EM2 is flashing between NOP and the engine=20 RPM. It flashes between the two while the engine runs. = What is=20 this telling me? What does NOP stand for anyway. I must = keep=20 reading over it in the manuals. Also, when I start the autotune = process,=20 NOP is displayed on the program screen.

Also, I have misplaced my books from = Tracy (the=20 Rotary Coversion Guide & the Mazda Papers). Could y'all = point me to=20 a link and/or provide some basic engine parameter guidlines such as = what is=20 the desired oil temp and water temp, preferred idle speed etc? = My oil=20 temp seems to be holding around 190 F and my water was going up past=20 210. I added an electric fan over the heat exchanger/radiator = which help=20 it get there slower. Now, to be fair to my system, this was on a = very=20 hot ramp, in a 100 degree Houston summer in bright sun. A bit = later it=20 clouded up and the temp went up much slower and was holding at about = 190 to=20 200 ish before I shut down to do other stuff.....well, actually, go = home and=20 eat the steak Jana made for me <g>.

Thanks for the time and = consideration. =20 Y'all are making this process MUCH more doable.

All the best,

Chris
