Thinking out loud on lean condition
Well, I have no money to do anything to the car for a while and I need to figure out why it's leaning out from 6,200rpm and up. If I can figure out what I need to do before hand, I can better plan my budget when the time comes. I only wish it were the tune alone but I don't think that's the case.
I calculated my injector duty cycle (I said duty) for my current power output and it recommended 50# for a 80% duty cycle. If I lower that percentage a bit it hits close to 60#. How close is that to being true?
Another factor is my MAF. It's a 80mm Lightning unit without an extender on it. Maybe the air isn't being metered correctly?
Anyone care to take some hip shots with me? I'm bored at work and need to do something to keep my mind working....
