Thread: Please define my Aeroforce Parameters

I posted a thread in the how to section on normal values.. Please take a look for it.

Trans Temp 0-220º, anything over 200 is getting warm

MAF SENSOR LB/M

MAF FREQUENCY 0-11,000hz. Completely depends on throttle input and how much air is going past it.

THROTTLE POS. PCT- Ask your foot, thats how far it will be open.

FUEL %

IGNITION ADVANCE 0-45ish, again depends on engine demands and throttle input. Cruising around 20-40, wide open throttle 12-16.

PULSE WIDTH Again, throttle input based. Going slow it will be low, 0-8ish, WOT likely near 13-16ms.

SHORT TRIM B1 -20 to +20

SHORT TRIM B2 -20 to +20 un-used.

LONG TRIM B1 -16 to +16.4, if you ever saw +16.4 you have a vaccum leak.

LONG TRIM B2 -16 to +16.4, We do not have a bank 1 sensor 2, so that is not even used. We only have 2 o2 sensors and both are called bank one.

O2 B1 0-990mv, is will always bounce back and forth between random numbers, it's trying to achive the stoich rating of the fuel.

O2 B2 0-990mv, bounces around untill warms up and stays near the .400 to .600mv range if the converter is working correctly.

IAC

ENGINE LOAD ask your foot.

TORQUE CONVERTERSLIP

TORQUE CONVERTER STATUS

Over half of those I dont or wouldnt even watch as they are kinda pointless to view.

Trans temp, intake air temp, coolant temp, ignition advanced, knock retard, MAP in/hgs for vaccum and boost readings, MPG and volts were really the only ones I cared to watch.

If you are ever looking for something by me.. search on "e asy" without the space and my user name.

Here's that thread

Map reads vaccum, all engine create a vacuum while running.

Different motors make different amount but 95% run around -18 to -20in vacuum at idle, it can go higher on the negative scale to say -23 to -25 with drops in throttle.

Anything over 0 vacuum is postive, so boost/psi. Most stock L67 3800's make 6-7lbs of boost.


And our cars only use B1S1 and B1S2. As for bank 1 sensor 1 and sensor 2. We do not use anything that says bank 2 sensor 1/2.

If it's always near 150mv and not moving at all, then that sensor could be dead.

It should be switching back and forth as the car warms up, then most lock in the somewhere around the middle numbers.

There is no BANK 2 SENSOR 2.

We only have a BANK 1 sensor 2, so yes we have a rear o2 sensor it's just called a B1S2.

Then don't worry about.

Not sure what else to tell you.
