So I just got torque pro set up and I have not looked at ICP and IPR since I had some work done. New oil cooler injectors and all that jazz

At a hot idle I am getting
580-590 psi ICP
And 22.8% IPR

Does this seem a little low or are these good numbers for a hot idle?

 

Both are perfect for hot idle.

 

I would expect 620-640 ICP for the 03/04 and 580 for 05+

MY BAD....You're right, I forgot about the 03/04 ran higher icp. I didn't pay attention to his model year.

 

Judging by his signature he is running an Edge tuner, possibly the reason for 580 ICP with the early motor.

Dang
Every thing high pressure oil wise was replaced except for the high pressure oil pump. Go figure. I just could not afford it at the time.
Will it be ok for a while like this?

When I had the work done they put back in 15w40 non synthetic Rotella.
I normally use 5w40 T6.

It always starts immediately hot or cold.
Will see what it says in the morning after its had a good cold soak.

I will also try returning to stock.

 

If the PCM sensed a low ICP issue idle it would jack the IPR to 27-30%. 21-23% at idle is perfect.

You're using the Edge too, right?

Yep those numbers were not on a stock tune.
I was on a 65 HP daily tune
I was monotoring on torque app.
I will return to stock in the morning and see what it is cold and after it warms up

 

Are you using an 03 ICP or the 04.5 and up? Post your ICP volts also.

 

No clue which ICP is in there. I will get out the invoice and see if it says. (Doubt it)
Any way to tell physically?
Will also post volts soon.

Thank you

 

Late model requires a 15/16" wrench. The early model requires a 1-1/16 inch wrench IIRC.

 

Awesome. I will check it out.

 

Even simpler. If your ICP sensor is at the back of the engine, under the turbo, you have the '03-early '04 engine. If your ICP sensor is on the right valve cover adjacent to the GPCM, you have the late '04 and up engine.

 

Reading the code descriptions for some of the ICP codes it says that if ICP drops below 650 the pcm is supposed to use default values. I have never observed this actually happen while reading data logs. Has anyone else seen this actually happen?

Sorry for the side track but it is related to ICP.

 

I know that, but I think one can still go in the other. "Same threads/pigtail"?
