I have code every now and then for the icp . Now I have a p0470, p1211, p0541.
The truck runs smooth but does shake a little when sitting and ideling

 

That's a whole lotta messed up right there. Hope it came with an instruction manual.

Baro s/b 14.6 or so depending on elevation.

Exhaust Backpressure, IPR duty cycle and ICP all look like the decimal is wrong. More likely numbers would be 11 psi EBP, 11% DC and 589 psi at idle.

Don't want to delve into IPW.

On the other hand the voltage and air temp look believable.

Is the truck a stick?

 

Decimals are in the wrong places on some of those PIDs.

ECT is not a PID monitored by the 7.3L PCM, so that will never be an accurate reading. Unless the truck is a manual, in which case some year models display this accurately.

Your Exhaust Back Pressure should be very close to MAP, or atmospheric pressure, at idle or with KOEO. If you are around sea level, this should be 14.7psi. If it is 11psi, this is low.

 

Truck is not auto. I thought I remembered reading some different numbers on most of it. But it's been awhile since I have read up on any of it

 

Is there a way to change the decimal??
I am in south east tx
The ect I wasn't to worried about. I have to chase a short somewhere. My dash gauge for ect stopped working and I replaced the sensor which didn't help

 

Not that I am aware of. I would contact SCT and let them know since it will likely have to be done in a firmware update.

I have seen a lot of issues arise with the Livewire on the 7.3L as far as monitoring and datalogging go. It seems as if SCT is working away from the 7.3L slowly and not offering support as they used to for fixing bugs.

 

I take it that the vehicle is running so that voltage is low. Should be around 14.1.

 

It's only going to get worse. OEM Parts were discontinued as well (unless they fit the 03-07MY as well. Dealers selling stock only until its gone.

Without people who are at least partially dedicated to the 7.3 like yourself, we'll all be in trouble in another 5 years or so.

Try to get service from anyone, The Red Truck or the most used Scan Tool here is all but gone. Literally.

 

Your barometric pressure is in Hg, we're more familiar with PSI.

The FIPW 1 and 2 have zero use. You're better off looking at transmission temp and torque convert slip in their places.

ICP duty cycle is off by a decimal, it should be about 11 at idle.

Running a hot tune will throw those codes. That's not to say the code is false, I'm saying a hot tune creates a situation that the truck doesn't like.

EBP is ridiculous, our EBP sensor maxes out at about 53 PSI. If you were in Alabama when you took this, I'll venture to say you won't have 11.4 PSI EBP under any circumstances, so that's not a decimal slip.

104 degrees F IAT on a rainy day? Is this an open-element intake (6637)?

5.89 ICP. That looks similar to a DP tune idle with the decimal off by two counts - it would read about 589 PSI

ECT is in total conflict with EOT... I'd dump that to prevent confusion. Pilots block/disable a malfunctioning gauge rather than be forced into staking their lives on possible disinformation, and they work with what they know.

Engine load - I never work with PIDs of this nature. Give me fueling, pressures, and temps - but leave the calculated stuff out of it. Bad math or altered tunes kill any accuracy this might hope to have (like the MPG on the overhead). MAP would be far more useful here.

 

Very true. We hear about this daily when guys call in looking for a PCM. The dealer tells them they cannot get one. Unfortunately, we no longer have them available for sale either for the same reason. Too hard to come by. About their only hope is a used one on eBay/Craigslist, or a reman from an auto parts store.

I have noticed this with other parts as well. It is sad, but a reality for all automobiles that are over 10 years old.

At least you don't have to worry about us. We will be tuning and supporting them until there are no more on the road.
