Hey i was just wondering what everyone thought about these logs, story behind this was i was tuned for 17psi on a 14b but i was told that it would be ok for me to go to 22psi, so i did. The car ran great for the longest time on 22psi, but now i upgraded to a 16g and im currently running 17psi and i just got a logger for CHEAP CHEAP. My goal is two run 22psi on the 16g. so i did 2 pulls and this is what i got

#1 log 3rd gear pull- 1st day 17psi

rpm timing o2 throttle,p
3220 33* .74v 14

3384 25* .80v 14

3660 18* .90v 94

3936 9* .90v 94

4264 11* .90v 94

4548 10* .92v 94

4852 10* .92v 94

5152 11* .92v 94

5532 13* .92v 94

5808 15* .92v 94

6072 17* .92v 94

6312 18* .92v 94

6564 18* .92v 94

6640 20* .92v 94

i think my logger sucks and i dont think its recording fast enough. it says im getting 7s/sec.... and it seems like the o2 voltage is maxing out at .92

#2 log 3rd gear pull- 2nd day- 17psi i logged more parameters here

4980 12* .92v 94% 21.02lb/min 59 190*

5384 13* .92v 26% 24.13lb/min 59 192*

6036 19* .92v 26% 24.13lb/min 59 192*

i let off at 6000rpms due to road ending, but is there anything you guys see unusual in any of the logs? any adjustments needed? And yes i know i need a wideband and its on the way AEM UEGO. I plan on turning the boost up to maybe 22psi, so any information would be VERY USEFUL and very much appreciated. Like i said before it looks like the values are maxing out at .92 and the throttle at 94%, dont know why though. Sorry if i posted this in the wrong place and sorry that the logs i posted are typed....thx in advance everyone and my mod list is up to date

^ gotcha, ya it looks like i might be getting some knock around 4300-4800rpms. Anyone else have any advice?

i was also told that i should change the byte timing on my logger cause im only getting 7s/sec. Does the timing look good at the end of the logs?

Any idea what happened in the second log at 4484rpm when the TPS value tanked to 6%? Also, Grescht is correct, you'll want to take a look at your TPS and make sure it's adjusted properly. The car is entering open loop, but your throttle plate might not be opening all the way. Either that, or the TPS needs adjusted so it sends the ECU the correct reading.

Can you run the byte timing test on the logger and then make another pull from 2.5k to redline, logging only the following parameters?

RPM
Airflow
O2 voltage
Timing

I'll also need your Hi Throttle Ne points and corresponding correction factors. That will allow me to calculate actual airflow and cross reference it with the stock 2g timing map to see if you are knocking.
