Wideband reads steady but afr in crome pro 1.6.5 the o2 voltage fluctuates from 0.5-1.6 with afr going back and fourth by a full point. Also batterie voltage moves around a small amount.

92 civic dx

Inovative mtx-l wideband

Powered by a25 yellow/black stripe wire on ecu

Grounded on chassis

O2 wire hooked to d14 white ecu wire

My p06 will datalog fine but my chipped p72 will not. It has j12 removed and a dataloging header. Also has another spot jumped with a blue wire.

 

Anyone? I read that only the ground wire would cause the o2 fluctuation in crome, dosn't make a difference where i ground it though.

Any ideas about the chipped p72 not logging but the p06 does?

what wires would work safely in the fuse box for power? (92 civic)
