How the heck are you suppose to tune the low throttle setting on the AFC with a logger. I am using MMCD and I have never figured out how to do it. I kind of ran into a snag when I lost my palm pilot and I am finally getting another one this week.

What exactly are you suppose to be logging and looking for when tuning the low throttle setting. Any help will be appreciated.
 
some people use the o2ft but I have yet to use that method with success but you use the LTFT and let the car fully warm up(may have to drive around a little bit), then let the car idle and watch the low FT and try to keep it as close to 100% as possible. Add fuel if the ft goes up over 100% and take fuel away if under 100%. these corrections will be done at the low rpm settings on the lo throttle adjustments of the afc. after driving more you may need to cerrect5 again. PM me if you have any more questions and I will try and help
