How do I see my air fuel/ratio on Predator

I have an a 1999 SS, I just purchased the SLP version of the Predator, I have looked at the real time data, but no where does it show what the air/fuel ratio is, just the short term and long term trims.....I'm a newbie so understand.

The guru's here will probably tell you that some Preditor models will display A/F ratios and some wont.

Regardless, the narrow band sensor in your car is incapable of giving an accurate reading at anything other a small window on either side of 14.7, so any other value displayed by the Preditor is a rough estimation... at best.

Look about half way down this page:

[quote="100LL"]The gurui understand the nbo2 and wideband, what I was trying to ask is what parameter do I look at in the U1798 predator that displays this a/f number....all I see in my tool is the lt trims and st trims....any help is appreciated

Read the tuning " Sticky"at the top of the opening page. Did you try going to the Diagnostics menu then choose Real Time Data then select "gas general short" scroll down and select Air Fuel Ratio.

when you go to monitor the real time data, you should have Air Fuel Ratio or Equivalence Ratio as one of the parameters to moniitor... if you don't have that in your parameter list, then you can not monitor it...

Don't feel badly, my brand new non SLP U7198 (yours should be the same model) does not have that very desirable data-logging feature either.
