This is not cat test, as it only happens during cruise. You can never idle and hit cat test... I have tried.

Welcome to the world of trying to run a xp/s1x/nic+ sized cam on a narrowband. It happens, its always going to happen. I have offered my solution up many times, and that is converting to run in full time open loop mode which eliminates false readings from the narrowband.
your right it happens when its first started and I start to drive . But it does come about randomly sometimes there after, so im guessing thats the true cat test

so using my aeroforce gaues (narrowband) to monitor my LTFT is , say, pointless? cause after a few maf tunes, everything seems in check, locks at 0 and runs fine

How is running in open loop going to change things? I have a wideband but unfortunately during the time of my cam install, the stainless DP on the car, has no rear o2 bung so Im waiting for that to be installed so I can run the wideband again

got a link to explain this? I have NO issues with my tune except for the random 16.4 , and you claim its from my tune not a cat test
