What does LT B1 and LT B2 mean? ST?

I know B1 and B2 mean bank one and bank two...but what is the LT and ST stand for? What is that percentage measuring? I noticed that HPT had some default red light area that you dont want it to go into...well my bank 2 is different than B1...it went into the red today, like 25% or something on B2. Does that mean I'm lean or something?

 

long term and short term... long term numbers are more stable and work off of an average, short term will help with pinpointing a quick intermittent problem

 

I need to go grab my laptop and look at the ST...I found out my LT went to 25% and that means I am dangerously lean...

 

Well it means that it is correcting 25%, but non the less yes it needs some attention. Ideally you want it -5 to +5. Me personally I keep my VE -3 to 0

 

I guess the good news is that it goes to about 8% on both banks when I go WOT...this condition was at cruising speed.

 

It should go to 0 on both banks when you go WO, because you enter open loop.
