Cross Count numbers acting weird

[BlackOut89]

Correct me if i am wrong but i believe that your cross count numbers on idl car warmed up are supposed to jump around from 0- 250 and cycle...

well i noticed the other day that my cross count numbers were acting funny. After the car is warmed up my cc numbers are not jumping they will just stay at a random number any clue as to why?

Another thing is while i am driving foot on throttle my numbers cycle as supposed to but as soon as i let off the gas the numbers stop...is this normal?? what could be wrong?

- I also want to add i just bought a new O2 sensor from casper electronics a few months back.

Sounds like you have an open loop idle chip. No cross counting occurs in open loop.

I have a turbo tweak street chip. So this is normal?

Pretty sure the TT chips are open loop idle, so that would be normal. The Extender chips goto close loop at 160 deg coolant temp. Don't know about the others.
