Im running 410 rwhp, and just logged my first run with EFIlive and I'm running 103-104% duty cylce with 30lb SVO's.. I have the log file if it would help anyone in diagnosing the problem, what could it be? Any other info that may be helpfull?

 

It could be fuel pressure or the tune itself. The duty cycle get's the % from the computer tuning,so if the wrong injector size,MAF table or even VE tables are in there it will screw with the duty cycle reading.I've had a car run 150% cycle before and never leaned out.Still running like that 1 year later with a ton of track passes.

 

Does that mean its ok, and I shouldnt really worry about it? Whats the best way to get an accurate a/f reading from EFILive without a wideband?

 

is my word not good enough.....

 

I checked for exhaust and intake leaks and couldnt find any.. Now I'm wondering if theres anything else I can view with efilive to figure out why it would be so high..
