The factory fluid is no longer manufactured...

Tryin' Lowest was towing the RV to Parma. Next one was city driving for a week. Then now back to normal hauls.

Know the feeling... As for tunes... I've managed to pull EGTs down to 500°F at 60 MPH. In town at 35 MPH it barely 350°F. I think I might reach back to mid 20s yet.

Mobil SAE 50 GL-4 transmission fluid what I'm running. The same stuff used in Eaton Fuller transmission in big trucks. Only spec you have to meet is synthetic GL-4.

Disconnect the Quad. Then probe KOEO.

Still need to ask about the wiretap is it good?

My current test of my tune in heading way up in cruise timing, EGTs are down to 500 to 550 at 60 MPH. I should be up in MPGs.

I didn't catch that the first time. I was looking more at the timing curve. Then the wiretap with 2200us pulse that should smoke like a train. That's why I wonder about the wiretap. It should roll coal. As for CANBus mine amps up to 140% or so but the very last entry is 85% in the 30+ PSI position (EGT control). Based on several hard runs and watching the backdown number this subtract the backdown from the 30+ PSI number and get your cap. Daily economy tune...

Most likely bought a damaged unit.

I'm the weird one I'm dropping the 65 MPH and going to 60 MPH to amp up the MPG number. cutting the cost per mile. Which with 125 trip 5 MPH drop means I've got to leave 10 minute early to make it in the same time I would at 65 MPH. But the cost per mile is reduced 13 to 14 cents a mile (60 MPH) vs 16 to 17 cents a mile (65 MPH). Why replace? Just adjust your schedule and drive 5 MPH slower.

Smartysupport.com yes... I'm the server Admin. Smarty Resource . com no... No longer working for them. They turned more phone based.

ECM failure? Did you do the W-T ground wire mod?

Watch out and be aware he only RV275 injectors.

Actually, that doesn't look too bad for a tune. I've got to ask about the wiretap now. Being you've got 50% pump tap fueling that should roll coal. I'm going to suggest you look at getting a Stealth Plate for tapping the pump.

I don't suggest this... Most end up losing MPG doing that mod. Then end up losing other things like cruise control. P-pump is great for racing but not for a daily driver.

I've got a bag of old light bulbs anyone wants some?

You could blow $1,700 on a Smarty Touch so you can have 60 HP tuner that is just as adjustable as a Quadzilla. Sad to say that same Smarty Touch on a CR engine now jumps from 60 HP to 210 HP. I'm sorry to say Smarty Performance King didn't put any effort into the Smarty S-03 tuner software which is the very same software on the Smarty Touch.

Just keep in mine that Smarty doesn't advance as far as the Quadzilla. Quadzilla can do a max of 32° of timing advancement from TDC. Then Quadzilla has timing controls to retard timing in the initial stab of the throttle to all for turbo spooling. Low PSI Timing Reduct Timing Reduct Scaling Then you have the Max Load Timing Offset so when you drop out of cruise timing it retards timing the set amount vs engine load this always for building boost just off of cruise timing when engine load increases. As a daily driver can use 1.0° or 1.5° of offset. Then as your cargo or trailer load increases, you can add more offset to protect the engine. While you all are playing with a little +60 HP tuner with unknown setting there is a 180 HP tuner that has full control of fuel and timing.

EGR valve is nothing more than a vacuum leak to exhaust stream. I would do a test on compression and see if the cylinder has damage. Then do a vacuum test to see if there is valve damage. You might pull the EGR valve and make a block off plate for test purpose. I typically make the block off from an old pop can.

2002 Cummins ISB was changed over to a single wire oil pressure sensor.

Hx40 has a weaker turbine shaft. This why the HX35/40 hybrid was made. The stronger HX35 turbine is used and then the HX40 compressor. Or... Some mod the HE351 turbo. Basically the same specs.

@dripley Is right 2002 there was changes done but the FSM don't show it.

My problem is I spend so much time studying how I'm going to do a modification or addon that it ends up taking serious extra time and part digging. Then figure out how I want it set up. Then actually building the setup. Some times it takes several months...

Most here go for the 62/68/12... My 60/60/12 HX35/40 hybrid I grabbed it for the fact I didn't want to lose my exhaust brake which most aftermarket turbos you end up losing the exhaust brake (turbo mounted) then moving to in-pipe exhaust brake.

Make sure to double check your passenger side battery negative terminal.
