scanmaster
For clarification, the Scanmaster is best for 1994-1995 OBD1 vehicles. It will NOT work on 1993's. The DTC function will not work on 1996-1997 OBD2 vehicles.
not to sort of hijack, but what can you do with the scanmaster? I've heard things like actively setting your IAC values when changing to a larger throttle body, does a scanmaster do this?
MAF - Mass airflow sensor (1-255 grams per second)
SP - Spark Advance (1-60 degrees before top dead center)
LP - Left Injector Pulsewidth (0-50 milliseconds)
rP - Right Injector Pulsewidth (0-50 mS)
DTC - Diagnostic Trouble Codes
MPH - Vehicle Speed in miles per hour (0-255mph)
LbL - Left Block Learns aka Long Term fuel trim (108-160)
rbL - Right Block Learns aka Long Term fuel trim (108-160)
CEL - Fuel Map Cell within the computer (1-18)
Lin - Left integrator aka Short Term fuel trim (108-160)
rin - Right integrator aka Short Term fuel trim (108-160)
02L - Left Oxygen Sensor millivolts (~100-900mV)
02R - Right Oxygen Sensor millivolts (~100-900mV)
AtS/IAT - Air Temperature sensor aka Intake air temperature sensor (-40 to 300 degrees)
CLt - Coolant temperature @ waterpump (-40 to 300 degrees)
tPS - Throttle Position Sensor voltage (0-5v)
tPP - Throttle Position Percent (0-100%)
r - Engine speed in rotations/revolutions per minute (RPM)
IAC - Idle Air Controller counts (0-150)
bAt - Battery voltage
Egr - Exhaust gas recirculation duty cycle (0-100%)
MAP - Manifold Absolute pressure sensor (0-32 inches of mercury = "Hg)
bAr - Barometric pressure (MAP before engine start = 0-32"Hg)
ACP - A/C pressure sensor (0-5v)
CCP - Carbon Canister Duty Cycle (0-100%)
It will also store the highest knock retard value of the last WOT run, to be recalled with the press of a button -- in addition to the O2mV when it occurred. If I recall correctly. Click here for more info.
