Vtech logger vs MTXL AFR
Has anyone noticed a big difference between AFRs on Vtech logger vs an MTXL?
my mtxl is showing 10s but vtech logger low 13s.

switching, only got one sensor.
Going to play with it again next weekend - MXTL had not been free air calibrated in a while so maybe that was the problem.
From my numbers last year the MXTL seemed to rich but vtech too lean.

10:1 would run like a bag of poo between 3000-6500 rpm

was in the 10s, probably closer to 11 but still bit rich but that was only really at WOT.
Have a feeling it was reading a bit rich though.
Might be time for a new sensor to be sure. Its about 2 seasons old now (and lived in the exhaust mani over winter)
edit: damn they are dear $90ish!

try a auto parts store first. I found the same sensor from my local pepboys for $49 vs $90+ shipping from innovate.
here you go. search for part #17014 at what ever parts store you guys got down there.
