how can I lean it out by changing the settings with the S-AFR?

could you give me instructions on how to change the settings to your specs using the RSP, Idle and Gain buttons since I'm not too familiar with it.

press and hold the GAIN button, it will switch to program mode from monitor mod.

now press down gain until RPM is lit up and then turn the Gain nob to select the appropriate RPM you want to lean out, then press down gain again. now % will show up now turn RSP or Gain can't remember right off hand, only one will work... this will lean it out, turn left to lean and right to gain.

now repeat the process to select all the appropriate RPM ranges...

where did you get the %'s from?

The mechanic who installed mine left it in factory settings so I can take it to get it dyno-tuned..

What settings do you have yours at? What %s so I can have a good base to start with until I get a chance to take it to a place for dyno-tuning.
