The tests and EGR I think it was in open loop, sorry I should’ve thought of that. I did take screen shots in close loop earlier but the wife was with me and for some reason she doesn’t like me playing as she call it with Torque in a White Out (Snow Storm).

The MAP range of my truck should between 50 kpa to 390 kpa, my gauge read between 114 kpa at idle to 345 kpa. So I’m in range I’ll have to watch it.

The boost from MAP were negative numbers, -60 psi highest value and 87.5 lowest value, I assume that it should be 0 at idle and not a negative number?

From the screen shot my coolant was 147.2 degrees F which matched ECT01 (147.2). Yes ECT02 is reading low for degrees F.

Capp777:
Here are the readings on the gauges at “Key On Engine Off” (KOEO). As for the units, I assumed standard over metric? I’m also assuming that EBP means Engine Back Pressure and not Engine Boost Pressure?

KOEO Test
MAP – PID 0187 = 16.2 psi

Boost from MAP – PID 0187 = -82.8 psi

EBP – PID 0173 = 53.7 psi

Bar – PID ? =14.4 psi

Just thing out loud!
Although Ford’s documentation mixes terminology between having a MAP or MAF, I believe it is a MAF that creates a boost value along with other sensor values. Am I right that the PCM’s has a PID for boost and should be calculated in the PCM?

I agree that the BAR gauge should read absolute pressure 100 kPa (14.5 psi), where I live and with the weather system going through I believe that 14.4 is correct.

The MAP/MAF sensor is reading 16.2 units and from the documentation it should read Absolute pressure. So I assume that it should read 14.4 psi (although kPa would make it easier to monitor).

As for the Boost from Map PID 0187, being minus 82.8, I agree that work is needed on that.

I’m hoping (believe) that our ECT1 is a temperature sensor is for the primary cooling system which monitors the engine block, cylinder heads, engine oil cooler, turbocharger and EGR cooler inlet.
ECT2 is for the Secondary Cooling System which is located on the outlet of the EGR cooler. This monitors the CAC, fuel cooler, EGR cooler and the transmission oil cooler.

Both systems have their own radiator, belt driven coolant pumps, thermostats and degas bottles. (Actually the primary system has two thermostats that open staggered by design, one opens at 194 F and the other opens at 201 F. So different reasons to monitor both systems.

Well I’m going to stop before I get more confused and try and work on the MAP and Boost. I’ll try changing the Map conversion and see if it matches the truck’s Boost Gauge.

Thanks Again, Hope that made sense.

All,

I was able to re-do all of the pids that were give awhile back. Here are screenshots of each and all of the responses. The last picture is also a screenshot i took before before I started taking screenshots of all of the pids.

Here is a new capture of my soot level. I have only had a minimal change over the past 200~ miles and I haven’t regened yet either.

I was also curious if this is the latest and best equation for the EGR Temp (PID: 22f46b)

EGR Temp (EGR_COT?)
Header: 7E0
Mode/Pid: 016B
(((B*256)+C)*0.0064)-4.0 or standard

(((B*256)+C)*0.007)-40.0

(B*1.8)-40

(C*1.8)-40

B*0.39216 (% for EGR Valve Position?)

C*0.39216 (% for EGR Valve Position?)

CACT1
Header: 7E0
Mode/Pid: 0177
(B*1.8)-40

(C*1.8)-40

(((B*256)+C)*0.007)-40.0

B*0.39216 (% for ?)

C*0.39216 (% for ?)

MAP?
Header: 7E0
Mode/Pid: 0187
((B*256)+C)*0.03625

Boost?
Header: 7E0
Mode/Pid: 0187

Note: I was reading 0 boost on my dash when I did this.

ECTs?
Header: 7E0
Mode/Pid: 0167
(B*1.8)-40 (ECT?)

(C*1.8)-40 (ECT2 Low Temp?)

(((B*256)+C)*0.007)-40.0

EBP?
Header: 7E0
Mode/Pid: 0173
((B*256)+C)*0.03625

Nox Reading (Non Regen)

Finally a reading of all of them together. ECT1, ECT3, and EOT are all accurate from the readings on the dash (I took this after driving home the other night and it was about 9 degrees outside. The temps from all of the individual pids were taken AFTER these were.)

I am confident in the Engine Oil Temperatures (some reason I have them in there twice), and ECT1 / ECT3. Those both match what the dash is reading.

The EGTs seem accurate and fluctuate appropriately. EGR_COT 4 looks accurate based on the other ECT’s.

The CACT (Charge Air Cooler Temperature at Outlet – Intercooler Outlet) ones I do not have a way to verify, but I would think that the lower 28 degree readings would be more accurate based on the outside air temperature.

On the boost, I will try and get one at 10lbs to see if we can tell any difference, but it is hard to tell according to the dash gauge for an accurate reading for that.

Bronco’s boost readings…

If you set the units to kPa and let
Torque convert to psi do the numbers
more closely match?

If my math is correct…

((((B*256)+C)*0.03687)-32.23)-[33]

This is based upon your dash boost
of 8-10 expressed in psi.

Bronco:

Sorry it didnt work for you. Hopefully
MPD56 is having better luck.

The math from the previous screenshots…

(3526*0.03687)-32.23=97.77 kPa
(5622*0.03687)-32.23=175.05 kPa

Your baro reading changed from
97.78 in first screenshot to 106.12
in second screenshot…

97.77-97.78= -0.01 kPa = -0.00 psi
175.05-106.12=68.93 kPa = 9.99 psi

I am not sure whats going on at this point
if the numbers are not yielding similar
results.

Your original Boost equation was off by a factor of 10. So I changed the equation. It now replicates what my dash guage shows.

((((B*256)+C)*0.03625)-[33])*.1

Can someone post the test response
for pid 0170?

I believe your boost values maybe embedded
in the data returned as reported by your
truck.

Merry Christmas to all!

Edit:

Boost
Header: 7DF
Mode/Pid: 0170
Equation: (((B*256)+C)*0.0048346)-Baro()
Units: psi

Without the test response I am guessing
at the variables.

Not sure what your using for a custom PID for boost but I’m not getting anything close to what my dash gauge replicates.
