Greetings Mr. @Cadillackid,
Which scanner has the most features and options if I wanted to convert the bus into a diesel-electric hybrid in the future? Would the Nexiq/Orion be best for that or would the scan gauge come in handy too?
I would like to remove the governor on the T444E (I think) and check for codes. It will crank but not run. or it will run but for less than 5 minutes and cut off.
Thanks for being a sage of knowledge.
P.S. is 4 years too long to re-open a post?

the scangauge wont display air pressure because its not a function on the data bus..
in fact on an International gauge cluster the brake pressure is a fully mechanical gauge..
on a DT466E / T-444E the 5 main gauges (temp, oil P, volts, RPM, Speed) are data-based gauges.. (no separate sensors).. they also log on the bus.. you can see them.. I think as Node ID 99 (id have to check my notes)..
trans temp and Amps are non-bus , but electronic sensor type gauges.. they use their own sensor.. a 0-5 volt signal return type sensor for trans temp and amps is a Shunt-to-gauge sender unit.
with an AT545 / MT643 the ECM has no control of the transmission.. all inputs to the trans are manual.. (cable or electronic modulator switch on the accel pedal)..
the gauges to most note are water temp (never never never go above 230!).. oil temp (230 is pushing it and 250 is danger danger!).. ICP requested and ICP actual.. you always want to make sure that the ICP is staying close to the requested value.. and at idle doesnt jump around crazy... IPR commanded percentage.. you want to see that duty cycle low at idle and never at 100% or can indicate issues with the sensor or possibly a leaking injector.. watching oil pressure on the scanner is good too.. if it hunts a lot it can indicate an IPR that is starting to go bad.
some nicieties you can read on a scanner are your digital speed, and your cruise control set speed digitally. you can also read your engine load factor and your fuel use rate, turbo boost PSI..
I use a NEXIQ device, and I have the API for it so im writing my own glass-cockpit software but the scangauge D is a quality piece of kit.. I have the scangauge II for OBD-2.. ive had that thing forever and it rocks..
