It's pretty accurate. Only takes about 3 runs and all the WOT stuff above the 2 step are done. Below that, still has to be done the old fashion way, by hand and trial and error. I think the Fast System will do the same thing from what you are saying, except you must do it cell, by cell ..

Do you ever have problems the idle after you transferred the changes to base? I have mine at learn only above 5000 rpm and anything below is open loop but I still have idle problems after I transfer the changes.
