Well boys I spent the morning logging some data on my truck. I wish I was computer smart enough to share it with you guys lol. I have a few screen shots though if that helps.
Ambient temps are around 35*F. Starts fine minimal smoke. Still (I’m going to say abnormally) low on power until engine is up to temp.
Everything I watched looked normal/fine except the ECT engine coolant temp. The temp when cold was around -230*F. It would slowly raise as the gauge on the dash came up to temp. Once at running temp the ECT was in the +180* range.
Do you think the sensor is bad and causing my problem as it had noticeable power loss when the ECT temp was below around 32 degrees?
Where would this sensor be located? Thanks for any help. Take care,
- Post the screen shots if you like.
- Do you know how to extract the data logs from the device?
- Are the data logs on a laptop or mobile device?
- If you are willing to email them to me, I can help with formatting, graphing and posting them here for others to provide their thoughts and input.
- I can walk you through the process of extracting them if you like if the quotes below from BWST here do not help.
Below is saving the data log instructions for Android.

When you are done taking data, tap the ‘stop’ button at the top of the screen. You may have to tap the screen once to get the toolbar to display. You can also just shut off the truck and the app will stop logging.
At this point, remember to save your data. On the Dashboard, Table or Graph screen, tap the 3 vertical dots at the top right for the save menu.
Tap ‘Save’, then ‘Save’ again to save the log in FSL format for later viewing in the application.
What I do instead is “Send CSV’ to save the log in comma separated value format and send it to my email. That way, it can be viewed later in the PID charting tool, using my PC or laptop (a bigger screen is helpful).
FSL will prompt you for your email, and then you can name the file and send it.
Now you have a logging session saved that you can view in the PID charting tool, an excel file set up for easy viewing of these engine parameters over time. It’s a great way to troubleshoot, because you can see how parameters like RPM, ICP and IPR% are changing, rather than a screen shot of one point in time.
Thanks again fellas that’s a lot of help! I did not save on my pc so I’ll be sure to do that the next go around. Maybe today I can get to it.. hopefully.
MAP reading includes atmospheric pressure. So it looks like it was pushing around the max reading possible by the sensor and about 24psi of boost. Does that sound more like it?

Thanks nailed it! 24psi it about as much as she’ll build. I did not account for atmospheric pressure.
I am going to vote for tired injectors as well. Mine with around 270k has behaved similarly since I bought it 6 years ago and it's finally on the list to do something about it this year.
At this point I think I’m just asking too much from cold oil and old injectors haha. I sure wish I had the cash for new injectors though. I think mine are on borrowed time.
A little more time to warm up is fine with me. Thanks again for the help everyone!
Andrew, these are old trucks and based on the image above, everything looks to be within normal operating parameters. Of course, that is a mere snip of the overall trip.
Like you and like I described above, my injectors and HPOP are tired at 260,000+ miles. Although, I can live with it a bit longer if that means I get to keep the $2,500 or so and time to install those parts and ride out the tired injectors/HPOP until they really need to be replaced. They still get the job done even out in WY at 9,000' towing up a 7% grade, so I am good with it.
On a positive note, you have some peace of mind, learned a bit about FORScan and can take a few extra moments talking to yourself, your passenger or your truck while waiting for it to warm up.

It can be a dicey proposition value wise depending on what you use or need the truck for. If it's just used occasionally where you can afford to be patient with it until it warms up, sure just keep running it awhile longer. Maybe try the thinner 5W synthetic oil trick if you haven't yet. I usually let mine sit and idle it's way up to at least 80-90 oil temp before I move it around the neighborhood. Compared to a little 4-cylinder gasoline grocery getter it's not a practical vehicle for short tripping around town for that reason and a few others.
