Early ICP in a late year model engine: Any benefits??
Cheezit sent me a PM recently with a very interesting question. It came from a recent thread on the interchangeability of ICP sensors. He has been wondering if installing an early model ICP sensor (03, early 04) on a late model engine (late 04 and up) might have some benefits. He gave me a brief summary of his thoughts and it sounded interesting so I scrounged up an early ICP to try on my 2006 truck.
I have no idea on how to really test out the theory, but I wanted to see if the truck drove any differently (or better for that matter), so I went for it.
Anyone game for posting up your thoughts on what the effect might be - just to get some discussion and some brainstorming going!
There truly may be no difference, but then again ........ who knows!!
Scott (Diesel_Dan) posted some ideas that I think were pretty good. I will quote them below to get this started! Hope you don;t mind Scott!
I won't copy the other posts, but I enjoyed them!!

Later pump is both more efficient and capable of higher pressure without issue. Quicker reacting, is, well a guess... Something that could be advantageous if one had a more effective injection strategy let's say... (a quicker turning **** so to speak).
How far off am I...?

So the PCM gets more accurate or faster and accurate feedback on what it is asking the IPR to do. It is another **** to turn in the complex system that creates a high pressure pulse of fuel.
If we have to "wait" for ICP to come up, we can't pulse the injector at perhaps the most optimal pressure/width for what our intended purpose is. We could send potentially different pressure/width fuel pulses, maybe even within a revolution, given the electronics are far quicker than the hydraulics of the system...
I'm not sure what it would help with stock tuning... But maybe it could.
Am I getting colder? And how come nobody else is playing?! Are they worried of a:

I have pics (or used to) in one of my albums. The site's database error message is popping up on me, so I might not be able to access the pics for a while.
The main difference is that the sensors "bolt surface" takes a 1 1/16 inch wrench for the early sensors and a 15/16 inch wrench for the late model year sensors.

I still envy your cats tho, but my cats would not ever want to meet yours (like in a back alley, or anywhere else
)they would spank my cats!

Sorry for the slight
The boys would want to play once Mokkun got over being a BIG Chicken.
Bella would most likely think she got a new chew toy. She has been
chewing on Tetsu this last week. And she was being a home wrecker the
last few days. I have to go replace a ceramic pot that she crashed into.
Right now she is sitting on top of the computer desk and grooming ME.
She pulls hair with that tongue of hers. 40# grit sand paper I think is
what you call it.
BTW what Mokkun thinks of all this typing
Sand paper tongue her self.
Tetsu The Thinker
Hot car. After the 2001 garage fire I think it sort of looks like a face.
I thought I would post a sort of funny. Well I can laugh at it now. Toyota Solara.
The Door opener failed at about 11PM everyone got out along with the cat at that time. I think the house suffered about $125K in damage.
