Hi !
I have a LQ9 engine with LS1B ECU. The engine has a BTR Stage 1 cam (223/230) and auto gearbox.
The engine has gone through tuning with hub-dyno and runs fine. However, the rpm oscillating at low TP/RPM/load/speed.
It occurs when drive at low speed (10-30 km/h) and low TP (11-13%) and no load (flat road).
Anyone knows where to start search for the problem? It seems that some parameter are to aggressive, but is it flow, timing or something else?
I want to record some data but what PID should I log?
