Scanmaster numbers / actual numbers

[TURBOPOWERED68]

Here is the deal.
Car running like crap
checked the MAF numbers and they were between 18 and 22 w/ translator and ls1 maf-- and 11 and 14 with a stock MAF.
Fixed setting on PL TO standard FROM 512 gps- Extender chip.
and now the car seems to be working better
is it my imagination? OR
Are the scanmaster numbers are just for the viewer?
OR
Is the ECM seeing and using the same numbers that the scanmaster is showing? thus the car running like crap because of the bad setting?
scanmaster, translator and PL on the car.

The PL setting does impact the signal to the ECM, only the setting in the translator impacts the signal to the ECM.

Pretty sure that power logger settings only affect how the data is scaled. The ECM deals with a 256 bit binary value and PL scales that to something we can understand.

Think about it this way. There are 5 analog inputs that really just read 0-5V. The PL scales that to values of 10-20 (for wideband) 60-1500 (for EGT) -29in-30PSI (for MAP)

Powerlogger displays 25PSI on the boost Gage but the ECM understands this as D2

so in dummy terms -- the only way i can think.
signals go from the sensor to the ECM - and the ECM uses that signal as is comes IN.
The PL only displays them for us in the form that we ask for them.

So yeaup it was my imagination -- add crazy to my list.

I thought that it might be possible for the PL to effect the MAF signal because of how the power logger can change chip settings.
then theres this
z-idle chevelle 9 10-30-2014 255 std picture.dat MAF setting set to 255 std. ----Same translator same LS1 maf NO changes other than on the PL
z-idle chevelle 3 10-30-2014 fan on picture.dat MAF setting to 512 extender chip---Same translator same LS1 maf NO changes other than on the PL

what do you think?

 

[TURBOPOWERED68]

compare the AFR and RPM lines

just noticed that the "fan on picture" was in closed loop and BLM learning.
That could be the reason for the big difference.

The PL setting does impact the signal to the ECM, only the setting in the translator impacts the signal to the ECM.

I meant to say "does not impact" can't hit all the keys anymore.
