Hey guys,
I just got a Palm Pilot that has the ability to put error codes and other engine information from any ODB-II GM car. I have been getting all kinds of data from my engine, but I am not sure what some of it means. If any of you guys could help me with some of this terminology I would greatly appreciate it. Some of them I know what they are... But I am not sure if & how they would be helpful in tuning & montoring my engines performance
1)Long Term Fuel Trim
2)Short Term Fuel Trim
3)Manifold Air Pressure
4)O2 Sensor Readout
5)Throttle Position Sensor
6)Injector Pulse Width
7)Knock Retard
8)Mass Air-Flow Frequency
9)Throttle Position Sensor Volts
10)Mass Air Flow
Thanks
