1405 lean at WOT
That's what we're asking! LOL.
A. Rod jet combo 2, 3, 23, or 26 will get much richer WOT on the primaries.
I'd start with 2, then try 23 or 26.
B. The guiding method here is one change at a time. Leave the secondary jetting where it is or return it to the baseline and leave it there for now. Heck, I'd rig them so they couldn't open but that may be more than you're willing to do.
By going to Combination 2, that is supposed to only change the WOT AFR. Then going to 26 will let you experiment with whether it will tolerate a leaner high speed cruise. Keep working on it step wise. Too lean at cruise the engine will rev and try to die. That's too lean. Test this in location you can safely drive back at slower speed, like 55 mph.
I erased the description low power because its not quite correct and may be misleading.
As the throttle is opened, the engine darn well better produce more power. And if its not a complete dog, it will make the most part throttle power with leaner mixtures. Leaner than cruise.
Nearing WOT and maximum load, the engine needs to get a much richer mixture.
If there's no load, the engine can run quite lean. You can wing the throttle wide open with the tranmission in neutral and it will rev to 5000 at 16;1 - no problem at all. Well maybe the engine won't like being free revved like that but that's another story. LOL
H'm. Interesting. Wonder why LM-1 is showing in the logworks screen shot.
Because I'm using the Auxbox for rpm I haven't made up a cable to try out the LM2 rpm input.
Since you're successfully using the pressure sensor, I would like to think that the other input functions are working. You may have to keep experimenting with the input signal or the table to get the rpm or frequency to function.
For the MAP, one procedure I usually add in the routine is to record a session about 20 seconds when the engine is shut off. it takes a couple of seconds for the MAP to show atmospheric pressure. That provides a reference for 0"Hg Vacuum.
