Feedback on logs?

[brandon19761]

Did some pulls and cant seem to get a solid a/f ratio set. I know my fuel settings are all over the place. Also my wideband reading is logging leaner than what my gauge displays and I have tried all of the aem wb options R1 being the most accurate. I used the sensor ground when wiring it to the ecu instead of chassis ground could that be the problem? I just realized it is smaller gauge than the chassis ground wire. The gauge reads within .1 at idle but almost a full number leaner at wot on the logs vs. the gauge reading.

Thanks for your time in advance.

Ok got my profile working now in case someone was thinking "what the hell we don't even know his mods". Thanks.

Great to see you have a MAP sensor! Now, you just need to calibrate it. Your goal is to have one line sitting on top of the other all the way until about 5k RPM's. These links will help you do idle, rev, cruise, and WOT fuel trim calibration:

You need to get your coolant temp and intake temps down. Your ECU is currently pulling 2* of timing combined for these.

Here is how the ECU views the coolant temps:

Enter ECU Learn Mode :: 170F (77C)
Coolant Fan ON :: 200F (93C)
Pull 1 degree timing :: 206F (97C)
Pull 2 degree timing :: 224F (107C)
Enter Open Loop Mode :: 228F (109C)
Default Coolant CEL :: 235F (113C)
A/C Override :: 240F (115C)

Here is how the ECU views intake temps:

185F = -3°
132F = -2°
100F = -1°
73F = 0
48F = 0
20F = -1°
-23F = -2°

You need to set your TPS to read .63v:

Also, keep watching your front o2 sensor. It seems to keep getting leaner as each pull progresses. Make sure it's operating fine (cycling) at idle.

Other than that, they don't look bad. I'm not sure what to tell you on the wideband issue. I know there's been plenty of people who had an issue so do some searching and hopefully you'll find an answer.

Once you make those changes, post up some more logs and we'll let you know how it's going.
