ICP Pressure

[yfzjim]

What is normal ICP pressure reading? I know it varies depending on rpm, load etc but I have seen some people reading 3000-4000 psi. Mine cruising at 55-65 mph unloaded hovers around 1400-1500. Is this normal?>

[pete322]

Thats what I see. cruising 55 in 4th gear @ 2200 rpms. hope to hear from some other people as well.

Sounds right. Mine is around 1200 or so at 60 mph on flat ground with no wind. That is on the stock vxcf4 file.

You can't get an accurate reading on a tuned truck, they manipulate the icp value for mor power.

You can't rely on the pressure reading because that's what the tuners use to keep the pressure up and it tricks the ipr to stay open. Check the icp voltage and that will give you an accurate reading.

I was too late. Portcity beat me to the punch

Yep, the only way to gets true reading is convert ICPv to ICP psi, analog gauge, or DashBoss.

ok, ill check the icp voltage and report back

[Msims02]

I believe my bully dog reads icp in volts because watching it icp show 1.4-1.5 and IPW show 2000-3000.
I'm fixing to run to the store and ill check again for sure

Here is one of my data log files. The first column in "time", the second column is "ICP Calc" that shows actual, the third column is "ICPv", the forth column is "ICP psi" that the PCM is showing what the tune writer had the PCM seeing to fool. This is with the SRL++ tune.
