precat = catalytic coverter that comes right after the turbo - part of the stock "down pipe"
main cat = catalytic converter in the middle of the exhaust pipe, under middle of car
TPS = throttle position sensor
ISC = idle speed control
VA = vacuum advance
psi = pounds per square inch - usually used in reference to turbo boost, vacuum, or tire pressure
RPM = rotations per minute - this is displayed on the tachometer
bcfpr= boost compensating fuel pressuge regulator
shp=sport handling pakage
tt=turbo timer or twin turbo
dis=direct ingnition system
mpi=multi port injection
tbi=throttle body injection
na=normally assperated(no turbo or super charger, all motor)
nawz=means your a moron...he he
o2 sensor=oxygen sensor
no2 or NOS=nitrious oxide
What? He's still around?

MAS/MAF = Mass Airflow Sensor, or Mass Air Flow.
1G(as used here) = First Generation, some state it refers to DSM(see next entry) cars as a whole, I state it stands for the 1st Generation of the Eclipse/Talon/Laser cars. Generally when a car is stated as 1G, it's the first ever body style/design of a specific car that lives long enough to be retooled over and over again, Such as the Corvette, Eclipse, RX7, Camaro, etc. etc. There is no Generation designation for the S/Q as it's only design was just cosmetically changed over the years, no major body/chassis change was ever implemented to create a 2G S/Q, thus necessitating the need to call the originals 1G.
DSM = Diamond Star Motors, a joint venture between Chrysler and Mitsubishi that produced cars such as the Eclipse/Laser/Talon, Stealth/3000GT etc. etc.
To add to that,
1G BOV, would simply be the "BPV" off of a 1G Eclipse/Talon/Laser TURBO, as the 1G BOV as everyone states it, was actually designed to recirculate the air, and not "Blow it off".
1G MAS, is the Mass Airflow Sensor from the 1G Eclipse/Talon/Laser TURBO's. This always refers to the Turbo versions, as the NA versions are useless to us.

KYBO: Keep Your Bowels Open, nick name for an outhouse, pronounced Kï'-bõ...
MAP: Manifold Absloute Pressure (sensor),
Stoich: Short for Stoichiometric, which in our case refers to A/F ratio. A Stoichiometric chemical reaction is one in which all the reactants are used up most efficiently. So, Stoichiometric A/F ratio is that ratio which is just right: around 14.7:1 by mass, but this varies with load and compression and other factors. If your engine is running stoich then it's being as efficient as possible. Stoich is what the ECU strives for in closed loop operation.
Closed Loop Operation: When the ECU uses info from the O2 sensor to fine tune the A/F ratio.
Open Loop Operation: When the ECU ignores the O2 sensor because it can't be trusted or isn't practical under certain conditions, such as engine warmup, hard acceleration, deceleration, ect.
