Whats ALL the parimiters that can be read LIVE on the U7198?

[LS1C5VETTE]

Can I read my A/F ratio while the car is running? Whats everything else I can read, I can find it in a search...

Do you have a Predator?
If so, plug it in and see for yourself.
There are alot of parameters that you can see, but A/F ratio is not one of them as the PCM does not monitor A/F.
You can see all 4 O2 sensors, the long and short term fuel trims, engine rpm, vehicle speed, etc.

Thanks

you will need a aftermarket wideband O2 System to monitor this.
