ye ill probably re-calibrate it and see what happens- list of weekend jobs is piling up lol but ye its about 1.5 months old

well you wouldn't think the sensor would fail that soon, might be worth emailing innovate too and see what they suggest ?

ye worth a try i'll email them a shot of the logs and see what they come back with- have u had any dealings with them? is there a long wait for replies?

Try logging using logworks too, see if the results are any different (log both at the same time if you can).

Have you adjusted the update speed of the MTX-L?

ye I've taken logs in Logworks also (in the same run) and it looks the same I've tried to play wit the data in excel but because the sample rate is different for the PCM and the wide band its hard to get the logs on the same graph i have to take a snapshot of data for the same time window and plot on 2 different charts but ye they are very close.

No I havent - is that via LM programmer and adjusting the "response speed" do u recommend making it slower than 1/12s (which is default i believe)?

Where have you got the WB sensor situated in the exhaust?
I've been using an Innovate LM1 for the past 6 or 7 years with numerous dyno runs & the LM1 always reads the same as the dyno WB.

No leave it on 1/12, the response being dampened the way it is on the fastest speed looks like the sensor is installed after the cat.

I've installed the sensor just upstream of the cat where the y piece merges into the cat.. I thought this was the best location for it as it gets both exhaust streams?

You haven't got a slight exhaust leak on the bank without the NB sensor?

Well I may have an exhaust leak somewhere but I haven't confirmed that yet- I haven't replaced a NB on one bank with the WB though. Still running 2 NB and the WB goes in just before the cat at the y piece merge
