Neil,
seems like a good bit of kit i have spent a lot of time looking at
the lm1 innovate meter, are you going to also use the aux lma-3 box
with the lm1, so you can have inputs for rpm, boost, throttle% etc
logged. and as nicole above sensor position before the cat if applicable
and DO NOT install the bung below the 3,oclock or 9,oclock position.
condensation can form in the exhaust pipe and permanently damage
the sensor, 6,oclock is the worst position to mount the sensor.
