-====== DSMLink Loggable Parameters ====== 
- 
-This page contains basic information for DSMLink'​s loggable data items including minimum, maximum and "​ideal"​ values and explanations of these data items. 
- 
-^ **Listed Name** ^ **Common name** ^ **Measurement unit** ^ **Min Display** ^ **Max Display** ^ **Min Actual** ^ **Max Actual** ^ **Ideal value** ^ **Description** ^ 
-| A/C comp | - | on/off | -1 | 2 | 0 | 1 | - | A/C compressor | 
-| [[afratioitem|A/​F Ratio]] | - | : 1 | 9 | 18 | 9 | 18 | - | Gasoline air/fuel ratio **estimate**. ​ This is only an estimate! ​ The calculation basically takes airflow per cylinder firing event and divides this by the amount of fuel that should have been injected during that same event. ​ The user has to tell the routine which injector size, deadtime, and fuel specific gravity was used by right clicking on A/F Ratio in the graph legend and selecting "​Props"​. | 
-| A/T D | - | on/off | -1 | 2 | 0 | 1 | - | AutoTrans park/​neutral switch. ​ On a manual trans car, this is the input used for clutch switch wiring. ​ If this value is changing as you press the clutch pedal, then you have not yet enabled clutch cut operation in the ECU->RPM dialog. | 
-| ACClutch | - | on/off | -1 | 2 | 0 | 1 | - | A/C Clutch | 
-| AEM35Bar | - | -inHg/+psi | -30 | 40 |  |  | - | AEM 3.5-bar pressure sensor | 
-| AEM5Bar | - | -inHg/+psi | -30 | 40 |  |  | - | AEM 5-bar pressure sensor | 
-| AEMWB | - | :1 | 9 | 18 |  |  | - | Gasoline A/F ratio from AEM wideband sensor | 
-| AEMWBgauge | - | :1 | 9 | 18 |  |  | - | Gasoline A/F ratio from AEM wideband sensor data.  This differs from the AEMWideband item in that this version works on the gauge type UEGO controllers rather than the non-gauge type. | 
-| AEMWBgaugeR1 | - | :1 | 9 | 18 |  |  | - | Gasoline A/F ratio from AEM wideband sensor data.  This differs from the AEMWideband item in that this version works on the gauge type UEGO controllers rather than the non-gauge type. | 
-| AirFlow | - | g/s | 0 | 400 |  |  | - | Airflow values. ​ Uses properties to define preferred units and limits. | 
-| AirFlowPerRev | - | g/rev | 0 | 5 |  |  | - | This is literally airflow divided by RPM.  It represents how much air is flowing into each cylinder per firing event. ​ It's useful for a number of things, such as checking that your airflow at idle is roughly where it should be (around 0.28 g/rev when displayed with the V2 app, 0.24 gm/rev with displayed with the V3 app). | 
-| AMtrFuelPress | - | psi | 0 | 100 | 0 | 100 | - | Autometer electric fuel pressure gauge | 
-| AMtrOilPress | - | psi | 0 | 100 | 0 | 100 | - | Autometer electric oil pressure gauge | 
-| ApexELBoost | - | -inHg/+psi | -30 | 40 |  |  | - | ApexEL pressure sensor | 
-| ApexELEGT | - | C | 235 | 1300 |  |  | - | ApexEL EGT sensor | 
-| AVCR3Bar | - | psi | -14.7 | 40 |  |  | - | AVCR3Bar displays boost from an AVC-R boost sensor fed into the MDP sensor input. ​ This is the 3-bar version, made by Denso. The label reads: "​DPS-310-2000A 949940-6270 5v". It has a socket on it for the AVC-R harness. The harness has 3 wires: Blue - Output, Green - 5 volts in, Brown - Ground | 
-| AVCR4Bar | - | psi | -14.7 | 40 |  |  | - | AVCR4Bar displays boost from an AVC-R boost sensor fed into the MDP sensor input. ​ This is the 4-bar version. | 
-| Baro | - | in/Hg | 20 | 32.5 |  |  | - | Barometric pressure sensor | 
-| Battery | - | v | 0 | 18 |  |  | - | Electrical system voltage as measured at ECU | 
-| BoostEst | - | -inHg/+psi | -30 | 40 |  |  | - | Estimates boost from airflow per rev.  On a properly configured car, this value should match measured manifold pressure pretty closely at WOT around 5500-6500 RPM.  Above this RPM range, BoostEst is expected to fall off from measured. ​ The BoostEst calculation is not calibrated to read accurately in any other RPM area. | 
-| CltchSw | - | on/off | -1 | 2 | 0 | 1 | - | Clutch switch (used for NLTS). ​ This value will only change after you have enabled clutch cut operation in the ECU->RPM dialog. ​ Until you check that box, the A/T D indicator will change instead. ​ More details on the [[cltchsw|CltchSw page]] | 
-| CoolTmp | - | F | -40 | 420 |  |  | ~200 | Real coolant temperature value. ​ This value does not include the coolant offset (if one is defined in the ECU->​Dash dialog). ​ To see the value used by the ECU for most stuff like [[FuelTrimUpdatePoints|fuel trim adjustment points]] or fan control while you have a non-zero value entered into the coolant offset field, datalog OffsetCoolTmp instead. | 
-| DynoJetWB | - | :1 | 9 | 18 |  |  | - | Gasoline A/F ratio from DynoJet wideband sensor | 
-| EGRSolenoid | - | on/off | -1 | 2 | 0 | 1 | - | EGR valve solenoid | 
-| FJOWB | - | :1 | 9 | 18 |  |  | - | Gasoline A/F ratio from FJO wideband sensor | 
-| FourBar | - | -inHg/+psi | -30 | 40 |  |  | - | Pressure value from 4-bar sensor. ​ Not generally useful as the mapping is only appropriate for a hand-built 4-bar setup used internally at ECMTuning. ​ Provided in the client just in case we need to send a datalog to someone that contains this value from our own car. | 
-| FrontO2 | - | v | 0 | 1.1 |  |  | - | Front O2 voltage | 
-| FuelPmpRly | - | on/off | -1 | 2 | 0 | 1 | - | Fuel pump relay |

-| GMIAT | - | F | -40 | 420 |  |  | - | GM IAT sensor (GM/Delphi #25036751) | 
-| GreddyBoost52 | - | -inHg/+psi | -30 | 40 |  |  | - | boost sensor used on Greddy Peak/hold 52mm gauges | 
-| GreddyBoost60 | - | -inHg/+psi | -30 | 40 |  |  | - | boost sensor used on Greddy Peak/hold 60mm gauges |

-| RawKnock1 | - | - | 0 | 255 |  |  | - | **2G only** - RawKnock values are used by the ECU to track knock sensor noise per cylinder firing event. ​ The ECU averages this value over time across the cylinders to arrive at a knock threshold. ​ Knock values above this threshold result in ignition retard accordingly. ​ Logging RawKnock is generally handy to see just how noisy the engine is or to see how much above the threshold a particular knock "​event"​ was. |
