Now to be even clearer, but not to step on any toes...
CT and PW are definitely NOT the same thing, but nearly all scanners display CTime as Pulsewidth.
You hit the nail on the head about CTime, no need to add anything there.
But with a DS4, Pulse Width is actually measured in arc angles by the Hi Res signal from the optic sensor. All other electronic diesel fuel injection systems will actually use Pulse Width in ms as determined by the PCM, and thus display the actual Pulse Width in ms. The closest thing to seeing the actual pulse width of a DS on the scanner is the Fuel Rate.
Also, 94-95 6.5s will set code 36 with CTime >1.9ms.
96+ will set code P1217 with CTime >2.1ms.
As you remember I posted a DTC 35, with my scanner(MT-2500) I now have a 35 and a 36, the Ctime mostly is 1.64 and when it hit 1.99 the SES tripped. it went to 1.99 when I blinked, prior to that the highest I saw was 1.68
my TDCO is -1.50 (is this right with a snap-on scanner??)
also act timming and desired timing always seem off from each other, edventually if load/RPM stabilises they match (I assume this is normal?)
Will these Ctime numbers change if I try a different PMD??
Do I need to worry about the pump or just unplug the SES??
