Lean during lifts - that's ok right?

Unread post by JBasham »

IIRC we had a conversation on the old board about the tune for my track motor. I'm out testing it today and it's stoich in maintenance throttle, rich by the right amount during WOT. But when I lift to shift or decelerate for a corner, and there's no perload to speak of, it's crazy lean. IIRC, that's okay right? I'm not hurting the motor?

lean is only a concern over half throttle

anything below that is perfectly safe it will just lower fuel efficiency and or cause a misfire

Thanks!

I'm writing that down in my EEC-IV notebook now, so I don't bug you again.
