Another ....somewhat Noob question

Can someone explain what all of these metrics mean on that the COBB AP measures? And what normal levels of each should be for our cars?

Any additional info would be great too like:

What mods impact which metrics, what is physically going on in the engine with respect to each metric, etc...


Here is the list (some are obvious):


Battery Volt - (obvious)

Vehicle Speed - (obvious)

RPM - (obvious)

Air Fuel Ratio - (obvious meaning, but what is the implication for our car/mods/whats normal?)

MAF - ?

Load Act. - ??

TPS Act. - ??

TPS Req. - ??

Baro Pressure - (obvious..i think?)

MAP - ??

Req. Boost Abs. - ??

Boost Abs. - ??

WGDC - ??

Timing CA -?? (whats normal?)

ECT - ??

Oil Temp. - (obvious)

Amb. Temp - (obvious)

Intake Mani. Temp. (obvious) I think without meth or FMIC normal is like 110 +/- 3-5 deg

Boost - (obvious)



TIA...
