Do a difference from your stock to the new injectors (bigger injector = smaller CLPAM) to get the ratio (eg 28 to 34's = 0.82 multiplier to the CLPAM.

Quick queston on "psuedo lean cruise".
I have a 05 CTS-V and copied the lean cruise and moved torque management from 350 to 640. From central Ohio to Philly, pa I got 30 going out and 28 MPG on return on a stock V. Should I turn off the rear 02 or does the lean cruise setup work for both 02's together?
I get mid to upper 30's in a C5 with headers and no cats with similar changes. Got to love it!
Thanks,
Norm
As far as I know the rear O2's only monitor the cats. They have no effect on fueling. Unless I suppose you get into a cat overtemp situation?
EC.. I forgot to say thanks on the CLPAM.
Changed the set up however, ABS haeds and Trex. I found a tune Scott had posted for the Rex. I'm in SD as his tune but renabled Ltrims. My wideband took a dump (sending it back). Still gets about 10mpg but can't verify AF. I have had to play with Ltrims and right now are pretty close to where they should be at cruise. Once I get the WB back I'll probably renable DFCO and change the O2 switching points. Hopefully that get's me more then the 10mpg I am seeing. I have a 150 mile trip on the 27th to the track. 2 1/2 tanks of gas would suck
Where is this in the scanner or what is it labeled. I might be blind though.

Not there, you have to infer it or create a table. It's simply your MAF airflow value at cruise.

No MAF.. So what would it be at that point..
Dynamic Airflow. (Not dynamic cylinder air though)

Super73 I was looking at your files.
I could not see your MPG in the .cfg file.
If WB is correct that explains your bad gas milage, you running very rich.
I would adjust the VE table a tad. atleast in the cuising rpms
MAF 20-45 and RPM 1200-2400
AFR ranged from low-10's to mid-11's, and the AFR error ranged from negative 11-31% in the last log you posted. Where was it showing 14-15 AFR, and why wasn't it matching what was being captured into HPT?
Please ignore the wideband readings at this time on my logs.. The LC1 needs to go back for a new one. Both A2D's are fried in the box. When it was working properly I had a solid mid 14 AFR. L-trims are all in the relm of -3 to -1 currently. Swapped to a 180* T-stat from my 160* and I'm at 9.5-10.1... I have not played with O2 switching points yet. I wanted to wait until my wideband was up again.
What effect will it have leaving the high table vvalue stock and lowering the first value to 375 with interpolation in between to make a smooth transition between the low to high switching voltage?
I take it this won't affect WOT throttle mixture as that is open loop only correct?
It could on cars that carry negative fuel trims in WOT.
What if my numbers in each block are already lower than the ones in your graph? I am trying to improve the mileage in my 2004 Tahoe.
I created this in my Scanner and it wont work on my 2004 4.8L Tahoe....any ideas?
It also doesnt work in my 2006 GTO either.
Any ideas? Tried it in a 04 GTO as well and doesnt work. I have checked and rechecked and cant understand why it wont work. I even followed the video on how to make custom ones to make sure I did it right.
Doesn't work for me either. Truck listed in sig. Scanner says 'unsupported'
I have the same truck and it works fine for me. post your files.
