I’ve also been looking at cylinder balance/ratio on my own van. Apparently the reading are taken from a central point and pick up the ‘noise’ from each cylinder. So the reading are not per cylinder, if that makes sense? And the sensor is central so the noise is greater on the cylinders it is close to.
I read this on the forscan forum.
Did you get pump/injector learns done?
Try some better quality diesel with a can of system cleaner through and see if this effects it at all?
Yeah, you are right it may not be related at all. Just seems coincidental.
I know there was water getting in the bonnet so maybe water ingress near the ecu, another transit owner had this happen and had the same cylinder contribution numbers. So I am hoping it is that.
Yes the injector and pump learns have been done a couple times now and don't help.
I think it is either electrical or it is related to the clutch and flywheel being unbalanced and affecting the sensors that read the position of the pistons etc.
and also the harmonic balancer is soft so maybe that is also part of it.
It just seems weird to me that it got worse overnight after the scv was done, i have no idea how that could change so much in one day unless the mechanics messed with it. which i will never know.
So next step is just to do the clutch and flywheel and see what happens then!
