As a relative newb at doing this stuff on the R3 and using the TuneECU program, I doubt that I'm the one to be giving anyone else advice or instructions on this sort of thing. I spent time reading other R3 captains' posts on this subject and the Tune ECU instructions before changing anything and found the information very useful. Thank you to all of them.
It did help that I had a little prior exposure to doing fuel/air mixture re-mapping using a PCIII USB on an '07 FJR, but there are plenty of folks on this forum who know so much more about this complex and interesting subject than do I. I will leave it to them to do instructional videos and such.
