ae82ted Posted July 12 Report Share Posted July 12 Working on an R34 GTT with GTTLink PnP, AEM X-Series WB02 connect via CAN. The AFR reading bounces vigorously at idle and low load areas, under full load WOT the reading is stable and usable. Never had such an issue with the cars I worked on before. The engine idle smoothly but just the readings are so weird. Any one has idea what's going on? The engine is with Kelford 264/272 cam, and it's not choppy at all.
