The OAT was 81, and the coolant read 225 on the temperature gauge, and the oil climbed slowly to 207 peak. The coolant did come down about 10 degrees when I throttled back at pattern altitude, but leveled off there. Sorry it didn't work out this time Steve, but it will, just hang in there. Refresh my memory- which gear ratio do you have, and what rpm's are you seeing in climb? What MAP are you running? 1) I seem to be running rich. I turned the fuel pressure down some (30 PSI on my gauge (don't know if it's accurate)). That helped, but running both fuel pumps makes the engine run very rich at full power. Turning off one pump increases power and smoothness. At an idle, 1000-2000 RMS, if I shut off the main fuel pump, the engine smoothes out, and gain a little rpm, before running out of fuel. This may be a dumb question, but why not tune this via the EC-2? 2) For whatever reason the "coil test" has stopped working. I used to be able to go to the "B" controller, and do the coil test to check the leading or trailing coils. That doesn't work, and if I turn it to off (I'm using the ignition switch), it keeps on running. Used to kill the engine before. I'm not sure what this is, and haven't really done any testing yet. First guess would be a fatigued connection somewhere.
