noob question
I'm new to to the scan and tune section and I'm hoping someone can give me some info on all the acronyms I see in this section. I know very little about tuning but I am trying to get a clue by reading thru the threads in this section and I don't understand alot of the jargon here. For example what is VE or SD? I recently figured out that LTFT means long term fuel trim and KR is knock retard. IAT is intake air temp? Is there a glossary or something I can read to help me understand the info in this section?

These are some that i know just off the top of my head.
AI - Alcohol Injection
AFR - Air Fuel Ratio
DFCO - Deceleration Fuel Cut Off
ECT - Engine Coolant Temperature
ETC - Electronic Throttle Control
IAC - Idle Air Control
IAT - Intake Air Temperature
IFR - Injector Flow Rate
KR - Knock Retard
KPA - Kilopascal (metric pressure measurement)
LTFT - Long Term Fuel Trims
MAF - Mass Air Flow (Sensor)
MAP - Manifold Absolute Pressure
PE - Power Enrichment
SD - Speed Density
STFT - Short Term Fuel Trims
TPS - Throttle Position Sensor
VE - Volumetric Efficiency
VSS - Vehicle Speed Sensor
WOT - Wide Open Throttle
I'd go over to LS1Tech and read some the stickies there.
