We all learn from each other mistakes and accomplishments...

Here is now my handy work on re-doing the ground wire and alternator cable.

I got to admit for the RV trip home was all uphill the whole way and I was beating on the truck pushing hard and fast. So the 13.9 MPG with towing the RV is actually an improvement. As for driving habits and gear use, I find that I can stay in 5th gear much longer now. 4th gear is rarely ever used on the highway but in the city.

Well, I can say that tire really hasn't changed much MPG wise... Started logging at July 2nd...

Fuel logs...

Here is the bus wiring... Then the 3 maps of the engine wiring...

Yeap... As soon as they gave up on carrying the fluid I did the hunt for my own fluid.

New Meadows, Idaho is $3.609 a gallon (Or about 0.81 euro per liter). I'm closer to his price. Ugh...

Then my redo of W-T article with lots of pics...

Let say I'm close to 400 HP now. My last transmission didn't like it... NV4500

Won't be able to handle the Quadzilla for very long.

Reminds me of my old 1972 Dodge Power Wagon I had years ago. Mine was a standard cab 360 CID with 4 Speed manual and 4WD. Boy, I love that old style body of those trucks.

They are good I've not dealt with them for many years. I bought a shift tower plate from therm years ago.

Throw a twist in this. Its 102*F sitting in parking lot I left the truck run and A/C on as well 25 miles traveled 2.2 gallons used and it reporting 8 MPG. Even by my math it should be 11.3 MPG.

That's excessive wide cycle... -67*F to 253*F that is way beyond what our VP44 really sees for the majority of Dodge Cummins owners. Like myself, I started this morning at 48*F and by the time I reached Ontario, OR it was 125*F in fuel temp. This is summer time. Typically my fuel temp follows closely to my IAT temp within 5 degrees.

Might call DAP and see if they can get it. You might be stuck calling transmission shops.

Spread the word I'm sure you can bring more to the member's map.

Most will suggest VCO nozzles over SAC. I'm running 7 x 0.0085 VCO DAP injectors.

As for the MPG display it has serious errors. If you travel 100 miles and consume 5 gallons of fuel you expect to see 20 MPG. Not... Like when I pulled in for breakfast it was now showing 26 MPG since that screen shot and miles was 109 and 5.2 gallons that 20.96 MPGs on my calculator.

The only way to measure CCD bus is by idle voltage. So after all the system stop talking you should have 2.49 and 2.51 volts between Bus + and ground and Bus - and ground. ASD relay issues most likely. You might look at the W-T ground wire mod to understand the ground system for the ECM, PCM and VP44. These two will help you with the ground side of the two main computers. Then my simple version...

Would be kind of cool if you place a member map pin over there in Germany... https://mopar1973man.com/membermap/

Time to ditch the Edge juice and replace it with a Quadzilla. Way better fuel to boost management. You can set all your fuel rates from 0 PSI all the way to 30 PSI (plus) boost. Then you can cut fuel rates BELOW stock value which an Edge Juice can't do. Not even my Edge Comp could do as good as the Quadzilla.

First off. PCM is the primary computer and the ECM is secondary. Either computer can shut down the engine. The P1694 code most likely points to bad CCD Bus between the ECM and PCM. You might check the PDC box and that big connector that is bolted down. When you tighten again be gentle it doesn't take very much tension to ratchet tight for it. Being it starts and runs with a hot-wired VP44 but not with the ECM that tells me there is an issue there at the ECM. The fact the WTS light is not coming on points to ECM that is failing to boot up completely. Basically, if you don't see the WTS light when the key goes ON then the ECM is not booted up and is brain dead till it does light up. So check again make sure you are seeing the WTS light before starting. Without that WTS light, the fuel pump relay will not trigger power to VP44. It will not start or run. You mention the possibility of security. You would have to check the central timer see if its a high line or standard. High line has the security feature typically and the key fob. From what I know if the security is set it should start at all and that is controlled by the PCM.
