How would it manifest itself in the graph & on the road? :happy2:

It would feel as if the power dropped off then came back on. On, off, on, off..
It would show up on the graph as dips and peaks, just like it is right at the top of the graph (but thats nothing to worrie about)..
Jacksones:
Just skimmed over this thread (well it's over 40 pages!), a really impressive build!
Yes it'll still be accurate if your front lambda sensor is ok. The post cat lambda sensor is there for emissions only. It measures the oxygen stored in the catalyst so the ecu can tweak it rich or lean to maintain cat efficiency.

^^ Would the AFR graph be accurate if I have a faulty Lambda post cat sensor...?

Going off the graph the map goes BOOOOOOOSSSTTTTTTTTT, flutter, flutter, flutter, flutter, flutter (wavey line), Fuel pressure drop (at 5.5k) then its run out of puff at 6250.
Need to see what that boost is doing, the requested vs actual and the wastegate duty. Runs leaner than I would expect too, and its working the turbo too hard when its coming on boost. Flutter is the DV trying (and struggling) to control the boost by opening and closing.
Just made to feel fast rather than drive smoothly and nicely esp without linear throttle imo.
Is there a graph with the boost on it?

Would you mind logging it when in for diff please Alex?
Graph with boost tap on manifold is on last page (middle one) :happy2:
