    shift special function?

    What does the shift option do in the special functions? Can you use this to to correct the input delay between the tps, map and o2?

    Not transients

    Hey guys I've been chasing down what I thought was transients but turns out it's the delay between the tps map and o2. How do I filter in order to line these up on the charts/ graph?:confused:

    Are you using a wideband? Tune the maf, first. It's easier. Be easy because the knock may be real. When you log see where the knock is and look at at the afr if its lean add some fuel.
