Oh, you might be right.
SO yah, Im not sure about knock then, I have a couple questions for innovate and need to give them a call, so Ill ask about that as well.
But anyway, Im using an Innovate OT-2, which is basically just an OBDII datalogger. It can be daisy-chained with other Innovate products, so you could for example add an LMA-3 and hook a map sensor to it and datalog boost with your other OBDII stuff.
Ive been using an Innovate LC-1 wideband controller for a while now, which Ive alwasy been impressed with, which is why I ended up getting the OT-2.
