notice how my fuel set to a steady 11.48:1 when under boost is that to low? also there are times when my af is really high like 23.83:1 at the end of my run why is that? and my injector duty is only at 62%, which isnt that bad for some 440 on 8.5lbs of boost right? In know some people who have injector duty rates at like 85 or 90%. if anyone is good with k-pro let me know.

11.48, should be fine for running boost. Mine sits about 11:5:1 and im pushing about the same only SC. As for the 23.83:1 your not on the throtle so its not injecting fuel in the cylender so thats what it does. You should be good. Have you had it tuned? or you just street tuning?

P.S. The Duty Cycle Should be alright. Your not Maxing them out. Im having fuel problems running 650's so i had to max um out to get home. They should be good to 500 Hp. the 440's should be good for about 300hp.

11.5:1 under boost is pretty safe. Thats not bad for a conservative tune. I'm setting mine about there as well. The 23.XX:1 is the LEV kicking in. once you take your foot off the gas the car basically keeps enough gas dribbling in to keep the car running. 62% sounds a little low to me, but I'm not overly sure on that. I know you're not supposed to really exceed 85% ish regularly but there's a lower limit on the optimum spray pattern as well. I just don't know what it is.

the car is completly dyno tuned three times to be exact, but some times i get a weird bogging when switching gears almost like its running to rich. another thing i notice i that my o2 sensor is reading 0.00v the whole time. I hope this sensor isnt bad i just bought it like 2 months ago.
My injector duty has never gotten over 70% mark, which is pretty good.

You running open loop? or closed?

 
Rep Power: 291

open loop, closed loop is only for tunning right? where you not able to look at the file?

Yeah i got the DL, just not the .Kal file soo i dont know lol.

ok, cool , just didnt know if it worked. so is open loop right? and what do you think about the o2 sensors? o and i also get a mil for running to rich i pretty much stay on the whole time. I cleared it this morning with the k-manager. why do is keep getting this code?

One more question, when recording a datalog how long are you able to record for?

Well i have some problems with my data logging cause i use a new lap top. For some reason they have trouble loosing connections. If you find like an old 700 mhz p3 computer they work better for some reason.

As for the O2 sensor, it may be burned out, not sure. But i would check for a loose connection, possibly a blown fuse. But ive been running open loop on my car i belive. I have to double check. But sounds right. Not sure about the rich part. but i was thinking maybe you might lean out for a min when you get that lag.. Do you have your lean cut on?

Im not sure ,where would that be under prameters?

another problem when i put in the tune that my tunner gave me on cd, when i try to open it, it says its read only! and wont open. any suggestions?
