ICP voltage gauge?

HobbyStock62 · Apr 27, 2014

I have isspro ev2s and am looking to monitor ICP before I make my injector choice. I can't seem to find a 0-5 volt ev2 guage. What are you people doing to monitor ICP?

Scangauge.

Isspro makes an actual hpop gauge, that splices into the icp sensor, which will read icp psi correctly.

Scangauge 2. also use it for IPR %, voltage, ficm voltage, coolant and oil temp. lots of stuff actually

I have an interceptor scan guage, it does not have ICP voltage. Different scan guage or something? But that isspro ev2 0-4000psi will read accurately because it is reading directly from the sensor?

Correct. It reads from the direct from the sensor, not through the computer like the others.

the isspro gauge will work or you can use an edge cts. sct livewire ts should support icp voltage soon too from what I hear.

Great, thanks guys. I'm gunna go with the isspro. Just going to have to figure out a place to put it...

another quick question. so 4.8v=4000psi, correct? basically if it drops pressure at all with stock fuel, then i will figure out a high output set up before i get more fuel. but what does it go down per 10th of a volt? and what would be considered reasonable? 4.5v?

Even if it spliced directly into the ICP...the tune can give a false voltage/psi reading on some trucks. My truck is one of them with Eric's tunes. My hpop gauge is tapped right into my ICP gauge....only saw 1500psi and 2.3v when tuned. Turn back to stock and I saw over 3600psi and over 4.5v.

Mine didn't. Also made the truck run like crap when it was plugged in

Well, they're supposed to work correctly.

Cutting-Edge Diesel · Apr 28, 2014

That was also like 4 years ago lol I have a video I will try And find it

strokin6L · Apr 28, 2014

i ran an ISSPRO hpop gauge for a short period of time and it worked fine. If you want to tap into the ICP sensor...use this http://www.strictlydiesel.com/p-2657-high-pressure-oil-gauge-install-pigtail.aspx makes life a lot easier when wiring it up.

Cutting-Edge Diesel · Apr 28, 2014

this is how it would idle when it was warm. would also max out at 1500psi. but might have just been my gauge and wiring I dont know. It had a piggy back harness.

sounds like how mine idled when it had the 305/150s and php ficm tuning LOL

Chris. I think we've had this discussion before. Putting the truck back to stock in your case pulled fuel back, giving you the higher pressure reading.

The isspro reads output voltage from the icp sensor. PCM cannot skew the that.

So how can you get a correct reading? How is the scan guage or the other one reading it? It seems to me that if it can be scewed right from the sensor it can be scewed from anywhere. If I plug in the snap on scan tool will it give me an accurate volt/psi reading?
