Datascan

Simple question for anybody experienced with datscan if my fuel mixture is good, what should my o2 sensor be reading in datscan?

it's reading between 82 and 92 under acceleration but when cruising it bounces between 5 ish and 90ish

also under acceleration it'll occasionally drop to 5 and come back up to the 80's and 90's again?


Any help with what I should expect appreciated

Also before I removed the cat (which will be going back in!)

When cruising with the janspeed manifold (have no data of O2 sensor)

But a/f ratio is bouncing between rich and lean?

not sure he's used datascan, bt gtir350 uses a power fc and datalogit stuff on his pulsar, he may be able to shed some light.......

DAVE DAVE WHERE ARE YOU!!!

Right I've found out it's due to only having a narrowband Lambda sensor.


now then, just got to find a wideband lambda sensor for the CG engine
