5ek injector trim codes

My truck was programmed all 6 injectors to 9850 can anyone tell me why. I cant find this trim file in your chart exaust temp was running hot at this got it set to proper numbers on injectors helped alot

 

hot trims are sometimes entered as a way of adding power. it stretched the pulse width and injection window in relation to crank position. Its completely wrong, but some people refuse to believe.

if you want more fuel, fit a bigger injector as opposed to stretching the pulse width. people that enter hot trims should have their hands crushed in a vice,

 

Wow, little harsh but I'm right there with you. Lol

 

It’s wrong on so many levels. But it adds power and you won’t see the damage/shortened service life for some time. So people do it.

It’s very difficult taking a truck with hot Trims back to standard without the driver complaining

 

So you're saying an engine shouldn't vibrate at idle because you've got it set like there's 6 different sized injectors in there? That's crazy talk lol

 

No it should idle smooth enough to sit your coffee cup on the engine and not spill any. But most cat reman injectors won’t do that.
And the problem will be worse with hot trims that effectively max the pulse width modification for each injector.

injector 1 might flow 30% more with a hot trim, injector 2 might only flow 10% more with hot trims. Making your fuel quantity balance between cylinders miles off

 

Anyone know how I can get the number off the side of the solenoid without pulling the injector or jakes?

 

Round dental mirror and flashlight.

 

That crossed my mind but I didn't think I'd have enough room for the mirror. You've done this yourself? Maybe I'll give it a shot.

 

Yes....just got to get the right angle in order to read it.
