    running lean on highway using aem ems

    My A/F gauge shows I am running well above 14.7 while xcruising down the highway. I am just learning about tuning with the arm unit and need a little help. What do I tweak to fatten up the mixture for highway cruising?

    You can turn on O2 feedback if you have your wb spliced into the ecu wiring. Then you can pick what afr you want at what load/throttle and how much of a percentage you will allow the ecu to pull or add fuel.
