First drive L92 with VVT and 4L70E LOG

[68problemchild]

Hey guys. Newbie here. This is the first real drive with an L92 with VVT and a 4L70E tranny.

Let me know what you think can be done. I am sure alot of very basic things are way out of wack so please let me know.

Thank you!!!

Here you go. Thanks!

You can remove some of the pids that are static or show no value.

Need an AFR pid, like whichever one is correct for your ECM.

RHS front O2 sensor (B2S1) is not right.

Both O2 sensors are not right, LTFT's are pegging positive.

[68problemchild]

RHS front is LC-1.

Does this mean they are working but hooked up wrong or not working at all?

Will log some AFR pids. Can you pick a couple? For E38 all I am seeing is "AFM inhibit reasons". PLease let me know of anything/other pids else needed/suggested.

Also, is it possible the harness is looking for the LC-1 on drivers side and NBand on the pass side?

If I just do both Nbands on each side, would the AFR work?

Looks like one bank fuel trim is 3% and the other is 50%+. May be the stock Nband is working but the LC-1 (pass bank 50%+) is not.

thanks.

The right front (B2S1) O2 sensor voltage HO2S21 is hovering at 50 mV... it should be swinging like the other one... if it's not, then do this:
use the LM Programmer software to set the LC-1 narrow band channel to 2.75V and see if this shows up on HO2S21.

(you have to re-power the LC-1 after programming it)

I see LONGFT1/2 both at 24%.

are you in high altitude? your map max is 85? if it is the ls3 bosh type map sensor on your engine you need to correct the scale.

[68problemchild]

Yes Nathans its the Bosch sensor. What should the map max be set to? I am in humid SW Florida.

Thanks!!!!!
