The update frequency being even 10hz won't matter, for some reason I can't get datarate higher than 9Hz anyway. It's *very* choppy sometimes, average datarate is 6hz but it'll run 10-11hz, then drop to 1.5 or 1.2hz and then jump back up. I've attached a short datalog that shows what I mean well. Once I get the datarate up to a steady value, the wideband fitted, and the VSS sensor reading correctly (it's currently unhooked, as the transmission has to come out to fix a leaking core plug) then it's time to just drive and tune-the blower belt alignment couldn't be better and it fires right off every time now.
