VVTI position hunting

Recommended Posts

Sorry I never got a chance to do a log, car was down for paint. In case anyone has this problem I fixed it by lowering the proportional gain to 3.0 in the vvti inlet LH control settings

What was your Proportional prior to it being reduced to 3.0?

The proportional for the 1JZ vvt mode is 6.0 when set to default PID mode.  This works ok for most 1J/2J's but I have seen a couple recently need lower P.  I dont know if it is related to wear of the hardware, oil viscosity/pressure, or some other variable.
