What a timely post,have just finished rewiring my harness due to "noise",was running in-line resistors and an ISCV,due to the location of the Ms had approx 2m of harness all tightly bundled together and all was well...until...decided to short the resistors and use PWM,all was well for a while then as the weather got colder she started playing up (I suspect the longer pulses due to ASE and WUP,along with more ISCV),could I find the problem..NO...couldn't see it in Datalogs but did notice inter-flickers on the spark output LED,sent the Ms to be checked (no fault) so decided to rewire the loom using shielded cables earthed at one end (Ms) and after a lot of work she's back to normal again....it seems the close proximity of the Power PWM wires to ? sensor wires "mucked" something up
I don't know if I went over the top shielding every wire (or pairs of wires) but it did the job for me..Happy Bunny
