9.2 KNR Powerlogger Files Attached!

[mtocrs1]

Need help guys.Two files attached. Changed nothing. First no knock. Second 9.2 KNR? WTF? Both rolling on the throttle trying to keep wheelspin to a minimum. Looks like I need some more injector. Running non progressive alky kit. What do you guys think?

Looks like duty cycle is maxed out , has a few frames at 100% TPS is a little low as well.

 

[mtocrs1]

but why?

Yeah, bigger injectors are needed, but why one time no knock the next time 9KNR? TPS is a little low however I set it just before performing these runs. Will get 4.62V full throttle. I guess I wasnt in it all the way. Scares me sometimes when I see the knock gauge light up like a chritmas tree.

Knock was at the shift point 2-3? Were the tires spinning?

Any way to verify fuel pressure? How much fuel was in the tank?

I have a hood mounted Fuel Pressure gauge but I cant say I was looking at it at the time of knock. Digital dash shows 12 gallons in tank but we all know how accurate the digital dash fuel gauges are. Maybe I will top it off and see if that makes a difference. How do most guys hook up a fuel pressure input to the powerlogger?
As far as wheel spin. Cant say for sure but I think they were spinning.

As far as logging fuel pressure with the power logger you will need a transducer. I got the one from caspers, not that difficult to add to the set up. I think full throttle sells one as well.
