[QUOTE="sath182, post: 1317133, member: 29607"] Thanks, that's the same form I had settled on using. I wonder if the dithering is encountered only in cruising conditions or if it's also present when rolling straight through the rev range like they recommend... That last bit is really interesting. I think it only applies to the main map though. I noticed that the adjustments on the trim table are not directly translated to the main map. I can't quite remember the numbers of an example off the top of my head, but it's not a 1:1 adjustment (especially on the enleanment trims). Picture you have a +20 on a cell in the main map. And the trim adjustment says -13. You would expect to come out with +7 after accepting the trims, but actually end up with something like +12. I"m gonna look for a nice open stretch of road this weekend and work on my trim tables by doing a series of pulls in 2nd or 3rd gear. Before I do that though, I need to make reference marks on my throttle grip for the percentages. Thank you, companion software, for making that incredibly easy. Too bad I don't have data logging so I can see what the measured AFR is for some of the trouble cells I'm keeping my eye on. [/QUOTE]
