I do love it! But so far the only things I've been able to scan are:

 

1) PROM ID

2) Coolant Temp

3) Start Up Coolant Temp

4) Throttle Sensor

5) Throttle Angle

6) Engine RPM

7) Vehicle Speed

8) Oxygen Sensor Voltage

9) 02 Cross Counts

10) Block Learn

11) BLK LRN Cell

12) Integrator

13) Idle Air Mtr Pos

14) Desired Idle

15) Barmotric Pressure

16) MAP Sensor

17) Manifold Air Temp

18) Fuel Pump Sensor

19) Battery Voltage

20) Spark Adcance

21) Desired A/F Mix

22) Injector Pulse

23) CCP Duty Cycle

24) Knock Retard

25) Engine Run Time

26) Catalytic Temp

27) Knock Sensor

28) TCC Status

29) A/C Clutch

30) Hwy Spark Advance

31) EGR

32) Air Switch Solenoid

33) Park/Neutral

34) Third Gear

35) Fourth Gear

36) A/C

37) Oxygen Sensor

38) IAC Motor Reset

39) Fuel Cut Off

40) Learn Control

41) Rich Lean Flag

42) Loop Status

 

I'm concerned/confused about this, why can I only test 42 different variables, when the AutoXray manual shows over 100+ for GM OBD-I??

 

Is there any books or websites that you recommend for more information on what various readings SHOULD be? In other words, lets say my "Injector Pulse" is "10.3 mS", what the heck does that mean to me?? What good is the information, if I have no idea what I'm supposed to do with it? Any recommendations are truly apprecaited!:)

 

THANKS!

Well..

 

On those parameters you listed.. mostly ECM if not all ECM.. There are a bunch of other codes not related to ECM including ABS on certain GM cars. The ABS controller alone can add dozens of additional codes.

 

As for the injector pulse, we're talking about a Fuel Management paramater that is continously adjusted by the ECM (hence changing) when the car is running. It does this with the help of inputs from sensors and also preset fuel logic and algorithms so it is not easy to pinpoint specific reference numbers. If you turn your air conditioner on you should see a change in the pulse as the ECM is reacting to increased power demand.

 

If you really want to get into the whole complex world of ECM operation and programming you can read about GM EFI at this site:

http://www.customefis.com/GMEFI.html

 

You'll find excellent introductory info there..

 

Hmm.. you sure it was 10.3ms and not 1.3ms?

Just curious.. :)
