I'm new to tuning and I'm in the absorb information and get familiar with my stock tune before I change anything. I was thinking if you had a RR couldn't you just command A/F to say 15.1/1 or so after you set the cruise control? Wouldn't that be a fast simple Lean Cruise? Is there a way to automatically grab the cruise active signal and set a different A/F when it's enabled???

Just wondering,
Ed
