on off long term fuel trim readings on my predator

[carmos]

hi all,iwhen i monitor my long term fuel trim on bank 1 and 2 half the time i get one or the other bank with some sort of number.the other bank is 0.is my predator broken?the one i did today shows 0 on bank 1 and -1.56 on bank 2. my car is a 2008 corvette auto.only mods are halltech intake and 160 trermastat... some times it shows figures on both banks but its almost random..thanks for any help.

p.s what i mean by 0 is it has no read out not thats its reading 0.sorry for any confusion.

that's normal... both banks won't be exactly the same...

if your numbers are 0 and -1.56, you're golden - right where you wanna be.

hi lew,what i mean by 0 is there si no reading in bank 1.so when u use redux software it says there is no data.when u use the data veiwer software u u see data for bank to 2 e/g. - 1.56 and there is no data on bank one.
here is the log. thanks

probably because your bank one ltft's are at 0... so that's why there's "no data"...

if it's at 0, there's nothing to adjust for....
