From previous dynotuning and datalogging on my old b18 crx (it was boosted) cylinder 3 leaned out on WOT. Do the K series motors have the same issue? Im creating my tune as im typing this and want to know if I need to add just a tad of fuel. Ill find out sooner or later.

Cylinder #3 does run a tad hotter, all my calibrations add a few % of fuel trim on #3 injector. Seems to keep everything happy. This is less of a problem with the K20Z3 and K24A2/A4's because of the coolant divertor.
