A friend had a diagnostic machine, thinks its an injector. This is what the machine said:

Is there anything there that will tell me what injector is in this engine?

If this were a mechanical engine, I would put that horsepower and torque at an 80 injector. But-since it is electronic, you have electronic injectors that work off programming. You can comfortably get 350hp and 1,000lb/ft torque out of a 6V-92TA. Maybe look into that. Good Luck, TomC

What are the active codes he has to go to the engine menu and select fuel injector info the engine configuration is not going to help him much, he will have 5234850- 1 or 2 model injectors some people just call the injectors 4850 fwiw
He will have codes 61 thru 68 for to long of response time 71 thru 78 for to short of response time he needs to check the injector height and make sure they are all set on .1520 those injectors are no different than a mechanical engine they have to be set fwiw

At this point they guy with the diagnostic is long gone. He was told to pull the turbo tube to see if the fins had any nicks in them, incase he blew a tip. Guess he'll just have to pull the injector itself to find out.

He can do what ever he wants owning a DDEC he needs a Pro/Link , the DDEC software or take it to a dealer he will be chasing rainbows for a long time without the Pro/link or software one injector he doesn't need will cost 1/2 of what a used Pro/Link will cost him JMO

Thats what was done. They dropped each cylinder out til they found the offender. Thats all the guy had time to do as he was on route somewhere and made a quick stop to help. Everything points to the injector on that cylinder. He was looking for the correct injector number before he pulled the current one. He wanted to have one in hand so he could be done with it that day.

Run at fast idle for a couple of minutes. and use an ir gun at each exhaust port on manifold and compare temperatures. May have to run it at a higher rpm if can't get much of a reading at fast idle.

That's been done. That and the diagnostic is how the offending cylinder was found. It was 30+ degrees cooler.
