What 10 items to you monitor. I have had this thing for a while and I am finally going to try to learn how to use it. From what I understand there are 10 items at a time so what are your page setups? Thanks. For those of you that do not know there are the following available:

Standard OBD2 Parameters:

Parameter
Description
Tyical Value

CLSD
Closed-loop status
0 (open loop) when cold

1 (closed loop) after engine warms up

ECT
Engine coolant temperature
185-220 deg F

IAT
Intake air temperature
30-110 deg F or more, depending on the weather

IGN
Ignition advance
Varies: 15-20 degrees at idle, 20-30 at full throttle

LD
Engine load (calculated by the vehicle’s computer)
0-100%, depending on conditions. 2 or 3% or so at idle.

LFT1

LFT2
Long-term fuel trim, driver’s side & passenger side
-10 to +10%

Zero after battery change or vehicle computer reset

MAF
Mass air flow
From 0.5-1 lb/min at idle to 30-35 at full throttle

MAP
Manifold air pressure
9-10”Hg at idle to near 30 at full throttle

MPH
Vehicle speed
Should match speedometer

O2L

O2R
Oxygen sensor, driver’s side

Oxygen sensor, passenger side
Should move around a lot after engine warms up; 850mV to 950mV at full throttle

RPM
Engine speed
600-700 at warm idle, up to 6000 or more during shifts at full throttle

SFT1

SFT2
Short-term fuel trim, driver’s side & passenger side
-10 to +10%

Zero after battery change or vehicle computer reset

Enhanced GM Parameters: (may not apply to all vehicles)

Parameter
Description
Tyical Value

FTC
Fuel trim cell
Varies with engine conditions. In general, numbers go up with load, except for cells 20-22, which may be used for open loop (including full throttle)

IAC
Idle air counts
20-60 at warm idle to 100 while cruising; higher when a/c is on

IDC1

IDC2
Injector duty cycle, driver’s side & passenger side
1-2% at idle, up to 85% at full throttle

IGNV
Ignition volts
12 volts or so with key on, down to 9.5-9.8 during starting, then 13.5-14.5 with engine running

IPW1

IPW2
Injector pulse width
2-4 milliseconds up to 15-20 at higher rpm’s and full throttle

KC
Knock Count
Zero to several dozen

Ideally, should always be zero

KR
Knock retard
Zero to 3-4 degrees

Ideally, should always be zero

MAFF
Mass air flow frequency
2200-2300 at idle, 9000+ at full throttle

MISP
Primary misfiring cylinder
1-8 if misfires present

MISR
Revolutions with misfires
0-10 revs is common; more than that may indicate problem

TPSV
Throttle position sensor voltage
0-5Volts; typically 0.5 volts at idle & 4.5 at full throttle


Thanks a lot,

John

inject pw, kr, boost, maf, map, mph, rpm, tps, adn two more that i can't remember off the top of my head. Any of you all have palm desktop 4.1? I have been trying to download it, but the goddamn site i am looking at sends an email to you to tell you where to download, but it never sends me the email. I really want to get this thing on to my computer so i can keep records.
