What coolant temps are you running? How about boost and EGT's?

Now you understand the feedback I use to gaining MPG's. Now if you set up the Scangauge II to display MPG, current MPG for the day and Current MPG for the tank then you can see the effects in all worlds. Also toss IAT up and watch the effects of IAT vs. MPG.

Correction. Need to see above 1000*F to burn carbon off.

I just ran into this problem but I'm pretty sure I know what happen in my case. What had happened was I made a trip to town and put my truck back in the shop and closed the door. Wasn't but a short time later I get a call to do firewood hauling. I pulled the truck out and set the A/C for MAX A/C and proceeded on hitching up the trailer. I start noticing the compressor pulling really hard on the engine and cycling rapidly. Thought that was odd I got back in the truck the vents were blow warm air. Compressor still cycling. Then I head the compressor struggle and then started venting freon. I knew then what was going on I shut down the A/C and left it off till I was rolling. I did open the hood and look and the fan was FULLY UNLOCK and barely turning. So what has happen the freon was preheated and pressure were to high and kicking out on the high side pressures till it got so high it was venting to protect the system (around 450 PSI). After I was on my way and got coolant up to temp and the fan was partial locked now the A/C worked just fine the rest of the day. So now experiencing this and seeing post in the past about warm A/C at stops I wonder if the fan is not properly locking and keeping air moving and the high side is shutting it down. Another possible occurrence is using Quickie Can with the hose included those typically have a oil charge with them and it possible to over charge with too much oil causing that problem. I've seen where condenser coils are so packed with bugs that air doesn't flow and freon temperatures and pressure sky rocket. Like today I took the time and fired up the pressure washer and slowly worked my way across the condenser, intercooler and radiator being careful not to get to close to the coolers.Today again it reached a 100*F here at my house. So keeping radiators, intercoolers and condensers cleaned is priority. So if your fan clutch is not locking properly to keep air flow moving the condenser will for sure get too hot and drive the high side pressure to trip the high side switch. So think air flow when the A/C is getting warm at stops.

Check this out rather cool.

No joke. Pun intended...

Welcome to the family Vini. As for the signature... Upper right corner of the screen is your user name "vini" now click on it. A menu will popup. Select Settings. Now on the left side should be Signature. Click and fill it in. As for 6.7L help talk to AH64ID or Wild & Free they are both good 6.7L tech on the site. As for asking question ask lots of question and be afraid of being a bother. That's what we are here for to help other people learn about their trucks. Again Welcome to the Family!

Talk about getting 4 cords of firewood in under 3 hours. I delivered 2 cords to a good friend down the road and bought 2 cords for myself. So I've got a great guy in New Meadows named Mike Dezey. He has his own logging business. So when there is a damaged log than isn't going to accepted by the mill he cuts the damaged chunk out and hauls this stuff home. Then turns around and sell red fir for $100 a cord or $200 for my trailer load. Spurce is $80 a cord. But with Stage II fire restriction this is a awesome option but even his pile is running out.

Hmmm. The thing is checks are out of date. Like I'm also converted over to all electronic means of payment as well. The problem is hackers going after large name brand stores more so. Like I've had my debt card hot swapped twice now. Because of the fact I had used it in different stores like Home Depot and WalMart. Even if I used a credit card still in the same boat. So I stick mostly to using the debt card for bill payment with the phone company and other things like this. So far I've never had a single issue with PayPal or my debt card usage paying the bills. So if you created a donation page on your site and linked Paypal to that page then you have a means of collection. Then you'll have to bind the Paypal to bank account preferably separate from the actual operational account (if your worried). Like M73M has it own account and Paypal is bound to it. So transferring fund back and forth can occur. Typical 3 days to transfer fund either way. In the past I was doing the long and hard way issuing a check, actually travelling to the bank to deposit the fund, then writing out the check and mailing. Pay for the fuel to travel 40 miles to deposit the check, then pay for the checks to be produced, etc. Way to much involvement with to many hands to lose the funds or be late with payments. As for checks they found ways to ink wash a check and re-write it out for thieves own purpose. So is a check safer?

From what I can find it a cruise control error always high. P0577 1T: Cruise Control Switch Signal High Input http://engine-codes.com/p0577.html

Vais01 do you happen to have a full listing of those codes? Maybe be worth publishing in the article database for others to see.

In the winter time when I was working at my fire station on vehicles I would drive away from the house another 5-10 miles to turn around come back home. This provided two things... One a good charge on the batteries because once the engine temp came up the batteries charge better. Also getting the engine to full operational temperature.

So I guess its time for other to go out and ask other members "What's up?" and see about coming back. I know some folks have sold there trucks or having other family issues.

Hate to say it but way better diagnostic tool that ScanGauge II. http://www.obdlink.com/ But ScanGauge II is a way better trip computer. Here is my old post... http://forum.mopar1973man.com/index.php?/topic/9895-obdlink-lx-and-android-tablet/

CANBUS started with the 2nd Gen's and continue to develop more so later. OBDLink MX has a WiFi series for iPhones. https://www.scantool.net/scan-tools/smart-phone/obdlink-mxwf.html This is just a sample of the what I was chasing after to give me the abilities to hack into the CANBUS and read engine data. This will be more of a winter project. Program manual for OBDLink LX https://www.scantool.net/downloads/98/stn1100-frpm.pdf

That's the first time I really looked at the wiring diagram... All I can say is Wow that's a confusing mess.

Basically the same as my OBDLink LX bluetooth dongle. The only I've seen so far is the OBDLink is use a bit more for CANBUS or CDD hacking. In other words lets say you want to take control of different things over the network some have grab stereo controls or lighting controls over the dongle. Both units use the same software basically. Comes back to the ELM327 chip and how much they designed to use of it.

It shifts at about 3,500 on the tach just touching the yellow zone on the tach. Red line If I remember right is 4k.

Problem is that with timing advancement the torque curve move up in RPM so advancing timing makes the power harder to reach during the cold operation forcing to rev higher. Then also the design was advance the timing to hopefully give enough time to convert liquid fuel to vapor to go BOOM. That liquid to vapor process takes longer if the cylinders and the air is colder. Make matters worse the 24V engine is the lowest compression ratio engine of all the engines to date. (SO @ 16.3:1 or HO @ 17.0:1) Even older 12 Valves where 17.5 or better IIRC.

No. It over advances the timing. This why I created the MPG fooler to RETARD the timing and bring it back to normal. When IAT and ECT temps fall the timing is advanced hard and rattling is very obvious. Then just flipping the MPG fooler on the rattle is GONE. It becomes quieter and and MPG's rise about a average of 2 MPG. Now I've got to clarify something. RACING/ HIGH PERFORMANCE Yes. You want to have a cold air intake. This is a must to controlling high EGT's and keeping the turbo discharge temperatures down while in high boost operation. Which will give better timing advancement and push the torque curve higher producing more power. But this is strictly for racing. DAILY DRIVER No. You want to take slightly warm air from under the hood. Being most daily drivers rarely ever hit high boost operations for long periods of time. Now if you trailer towing a lot I would suggest the cold air intake if you running the mountains and towing. But empty daily driver I highly suggest IAT temps of 100-140*F. Because when you retard timing it puts the torque down lower producing the power easier at lower RPM's. Not to mention it does provide the heat needed to quickly ignite the fuel where cold air can't. As you'll see the turbo discharge is high but the intercooler knocks it back down. Now a daily driver with low boost will not produce enough warm to make the engine efficient.

I'm worse yet. Get a fire call start the truck cold and run hard with high boost at 60-65 MPH for about 1 mile and shut down. The fire up the Ford 7.3L diesel and transfer gear from my truck to the fire truck and run the hell out of the Ford (3k RPM) getting to a fire call. So when I do get a chance to hitch up the trailer I'll haul trash or maybe just haul the RV for a gentle pull to build heat then get into and cook the carbon out. Then come back and idle to cool down. As for block heater use year round is fine. It will get to about 110 to 130*F worth of coolant. The element is a 750w heater so its like a space heater running 24/7 non-stop. Winter front will help but if all your travel is stop and go traffic it will take more to warm up. You not producing any EGT's to get temperature built up. 3/6 Cylinder high idle would work better. You could set 3 cylinder high idle and then have it warming up a bit and then leave. But in any case this will cost fuel.

I really do like my new OBDLink LX...
