Logging Parameters and Their Meaning

[Whytiptoe]

So I have looked at N54tech website for this info, but if someone could assist me that would be great. I am looking to learn what they are for the KIA as most of this is for the BMW's motors. Thank you in advance for your help.

Timestamp = time since logging started
RPM = RPM of engine
ECU_PSI = ECU/DME observed boost
Pedal = Gas pedal input
IAT = Inlet air temperature
Fuelen = value changes on firmware and engine type
Firmware 10, Lambada II T-GDi. So what does Fuelen mean?
Wgdc = not listed but seams to be always 0
Throttle = throttle blade position (0-100%)
Fp_h = fuel pressure high system
Calc_torque = not listed
What does it mean, I can take a guess
Dme_bt = DME boost set point
Meth = Methanol flow
Fp_l = fuel pressure low system
Gear = Current selected gear.
Stinger seams to always be 0
FF = Feed Forward
Load = DME load index
Clock = not import to anyone other than BMS
Map = map selected
Trims = fuel trims
Trims2 = not listed
AFR = AFR for bank 1
AFR2 = AFR for bank 2
ING_1,2,3,4,5,6 = ignition advance cylinder 1,2,3,4,5,6
Avg_ign = Average ignition retard for E series and some F series models
So what does it mean for the Lambada II T-GDi
Oilf = not listed
Can take a guess, but seams to always be 0
Waterf = not listed
Can take a guess, but not listed
Transf = not listed
Can take a guess, but seams to always be 0
E85 = not listed
Target = JB4’s target boost
Boost = PSI in charge pipe
Boost_2 = not listed
MPH = not listed
Don't really need anyone to tell me as it is MPH, just not listed.

WGDC is generally wastegate duty cycle. It will only increase when the wastegate controller is trying to bleed boost from the wastegate actuator to prevent the wastegate opening - the actuator will generally have a spring to hold the wastegate closed, and that spring is generally sized so that a given boost pressure over-ride the spring tension and opens the wastegate, which lowers boost. A wastegate controller is used to allow more boost than would, on its own, open the wastegate via the stock actuator (so a turbo setup generally has a value called "wastegate pressure" which is the highest boost you will get in limp-home mode (in this mode, boost control is often not available.

My guess is that oilf, waterf and transf are temperatures, but they require a sensor to obtain them.

Calc_torque will possibly be the torque figure based on engine parameters that is sent to the TCU to help it make decisions on gear changes.

Fuelen is fuel enrichment.

It will remain at 0 during normal driving. Under WOT the values will fluctuate as the AFR is leaned out. This value is what the fuel wires control, which then has an impact on AFR. Without the fuel wires, the car runs rich and will misfire particularly on Maps other than 1.

E85

I mean we know what that is, as it lets the JB4 know the ethanol content feeding into the HPFP, but the value will be inaccurate unless there’s a FlexFuel sensor and an accompanying 0-5v signal wire attached to the JB4.

Trims = Fuel Trims on Bank 1
Trims2 = Fuel Trims on Bank 2

Ideally, you’d want the values to be in close range of one another.
