Thanks, odd units for that axis.
 

That is Nye's XDF

Presently I am logging the following variables with ME7Logger:

nmot (RPM)
gangi (GEAR)
wdkba (ThrottlePlateAngle)     

pus_w (BaroPressure)               
plsol_w (BoostPressureDesired)
pvdkds_w (BoostPressureActual)
ldtvm    (BoostFrequencyValveDutyCycle)
mshfm_w (MassAirFlow)
tans   (IntakeAirTemperature)
zwout (IgnitionAngle)
 
dwkrz_0  {IgnitionRetardCyl1}
dwkrz_3  {IgnitionRetardCyl2}   
dwkrz_2  {IgnitionRetardCyl3}           
dwkrz_5  {IgnitionRetardCyl4} 
dwkrz_1  {IgnitionRetardCyl5}                     
dwkrz_4  {IgnitionRetardCyl6}                     

rkrn_w_0  {KnockVoltageCyl1}       
rkrn_w_3  {KnockVoltageCyl2}                   
rkrn_w_2  {KnockVoltageCyl3}                                         
rkrn_w_5  {KnockVoltageCyl4}   
rkrn_w_1  {KnockVoltageCyl5} 
rkrn_w_4  {KnockVoltageCyl6}   

vfil_w  (SPEED)

fr_w {LambdaControl}   
lamsbg_w (AirFuelRatioDesired)
ti_b1  (InjectionTime)
tats_w {EGTSensor} 
tats2_w {EGTSensorBank2}       
tabgm {EGTModelBeforeCat}           
tabgm2  {EGTModelBeforeCatBank2}

usvk  {O2SVoltageSensor1}         
usvk2 {O2SVoltageSensor1Bank2}
rl_w  (EngineLoad)
fzabgs_w  (CountMisfireTotal)

Lots of information out there, but this document does a great job at getting some of the very important fundamentals across (attached).

My advice is to read as much as you can get your hands on... If you're the type that learns better hands on, get friendly with some local shops/engine builders or consider a course for ICE or even tuning (beginner courses usually touch on ICE basics).

A lot of basic info but was a good read figured id share https://drive.google.com/file/d/0B9AlTN-WfgmnN2huYjhaRnJFcGs/edit?usp=sharing

Very cool ^ So when you hit the switch for cat efficiency it sets the value to whatever the mask is in the XDF perameter to bit 0 or 0x01?

I know, technically everyone should read the FR and understand how ME7 converts load request to boost, but that's beyond the scope of what we're trying (at least me) to accomplish here. Once people see appreciable results from their OWN work, I think that'll create the drive to dig deeper. I feel as though if we keep the redundancy to a minimum, it'll prevent a lot of questions later.

With that being said, I'm just approaching this based on the questions I get most. I would love to hear from some of the new members, fresh off the boat. I figure I'll add map names in parenthesis in the xdf descriptions for the stage2 xdf, that way the natural progression steers people in the right direction.

HOWEVER:

These are just my thoughts. I don't want to monopolize this, or trivialize anyone's ideas. That's not what I'm about

As a kickoff I think the XDF is excellent.

I could live with LDRXN not being in PSI, but that's only because I do a separate calculation on a spreadsheet to get an estimate for what PSI would be.  For now leaving it as PSI is probably the way to go, erring on the side of simplicity is my preference, it's easier to introduce advanced concepts after a basic understanding has been established rather than getting bogged down trying to explain things that could have been avoided in the first place.

For those following along at home, should we have set the Rev limiter and Speed Limiter at this point?  Looking ahead, next we will...

I think having both versions in the xdf (load and psi values for LDRXN for example) and so on would be great to help people learn on their own the relationship between the two. Once they get comfortable they will most likely move over to using the tables/maps correctly (load values for LDRXN). Just took a look at the xdf...Might also be good to add the ME7 acronym along with it's English description for the maps, and adding axis descriptions for the ones that aren't obvious. Great job by the way!
