P0171 & P0174 SC 2010 Camaro

[opcode]

19982
19983

Mods:
LS9 cam
2" TSP LT's
Whipple 2.9L w/ 4" pulley
3 bar MAP (1bar tune AFAIK)
JLT CAI (110mm ID at the MAF)
E85 flex sensor (issue happened before adding the sensor)

I've reinstalled the supercharger twice in case a ring seal was broken or twisted, and I cannot find a vac leak anywhere!
No WB yet, my lm-1 seems to have kicked it.

Thanks

Does your FPR have a manifold-reference hose... if so remove the hose and check for presence of fuel (i.e. FPR is leaking into reference).

What is your rail pressure (measured with reference hose temporarily removed)...?

Are your injectors leaking...?

Are you injector tables correct for your injectors...?

[joecar]

Is your VE/VVE corrected...?

[joecar]

For your wideband, you also have to log EXT.AD1/2.

[joecar]

For INJ1DC you also have to log GM.INJPWB1.

[joecar]

Your log does not contain HO2S11 and HO2S21... I want to see these.

looks like 1 bar sd tune based vve, but full time maf for fueling, yikes.

I think you need to look at doing a 2bar map sd tune by disabling the maf.

i also hope you didnt pay for that tune.

Here is a log w/ the added PIDs with the exception of the ad1 which will be a fuel pressure sensor and the wb02 both of which I have not received yet.

No, its the stock Camaro SS setup w/ a ZL1 pump and should be set @ 58 PSI
The injectors (Siemens Deka 63lb) and tables are from the tune that come w/ the Whipple kit.


Is your VE/VVE corrected...?
I have not made any changes since I currently do not have the proper equipment (its in the mail), however the tune was 'made' for this setup and so should have been corrected.

...Measure it (at the rail) anyway.

Measure it (at the rail) anyway.
Thats the plan, just waiting on the sensor. The Whipple has a port for a sensor but no valve for a quick check

I'm looking at your log...

( sorry, I should also have said "please log GM.ETCTP also" )

Attached includes GM.ETCTP and the serial WB data.
No FP yet.

Thanks for the help!

I'm still looking, I'm running behind (hospital stuff) please bear with.

Hey, take care of you and yours. I just don't want you to be waiting on me, I'm just thankful for the help.

I was able to get the fuel sensor in today. It reads 2.94v @idle on ad1, assuming I did the math right that's 61psi at the rail.

Min PSI: 0
Max PSI: 100
Min V: 0.5
Max V: 4.5
------------------
Slope: 25
Intercept: -12.5
PID: "{EXT.AD1} * 25 - 12.5"

Take care and thanks for everything!

E38_0016.efi (https://forum.efilive.com/attachment.php?attachmentid=20011&d=1469312664)At idle, HO2Sx1 are very low (almost zero) and do not switch...

this indicates either of the following:
- air leak somewhere in-between MAF and front NBO2's;
- MAF could be under-reporting;

( at part throttle, your MAF seems to be a bit low )

this is causing g/cyl to be low, which causes trims to go high and meet the criteria for setting the bank lean DTC's.
