Re: ---===The Official MAFT-Pro Thread===---
also at idle, if the O2s are not toggling, rev the engine and then watch the O2 trim when the engine returns to an idle. If the O2 trim climbs, the idle tune is too lean, if it falls (from 100) then its too rich. If the idle trim is too far out, the ECU tried to toggle, and then gives up and picks an open loop idle setting.
