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.

Just for my head gasket job... Head gasket kit, replaced 18 valve guides, valves, surfaced, checked for cracks, etc. Was right at $2,000. Just repaired the damaged stuff and installed. Still in all, there is no sense in any head work unless you plan on WOT nearly all the time. Just not going to be any gains... Yeah signature would be good...

That Edge Comp isn't going to be set up for 150 HP injectors very well. I tend to agree there is something wrong with the Edge Comp box. I've got to ask was this the proper Edge Comp for this engine? You didn't modify the MAP sensor leads to make it work? Then being your missing the PCM there is no way to read error codes. I would disconnect the Edge Comp and run without it and see if the problem goes away.

If your injecting the fuel too late and the ignition is occurring after TDC then the power is completely wasted and fuel most likely isn't being burned completely. Might see a gray haze. Then what is your CANBus fuel curve like? Then what is your wiretap settings like? Yes. I know exactly how to create massive smoke that just proves that your way over fuelled and wasting the power. Black smoke could prove that your timing is off depending on when the black smoke is seen. Black smoke is not good period! Just means your flooding out the engine and lacking boost pressure.

Exactly... Majority of us are just daily drivers here. None of that will amount to anything being you don't run WOT all the time. Like myself, my average engine load is 17 to 19% and about 2-3 PSI of boost at 65 MPH. Flow is super low so there is nothing to gain by porting the head. Now if your 1/4 mile racing, dyno queen or tractor pulls then your going to see some gains by porting and such where you run WOT nearly 100% of the time. Just upgrading 3-inch exhaust to 4-inch exhaust on my Cummins gained me ZERO. No change in MPG, no change in EGT's, no change in power. Just like intakes don't gain anything for daily drivers because the flow is too low. Now as for injectors (7 x 0.010 @ 320 bar), turbo (HX35/40 hybrid 60/60/12), and Quadzilla now that had produced serious power gain. EGT very controlled. MPG at 20.64 at the last tank. Can tear the tires loose on command. Awesome sprint truck. Drop the hammer its passing 85 MPH in the length of a semi-truck from 45 MPH. There is more to it being I've got a correct final gear ratio to the ground at 3.69:1 where most are on oversized tires and below 3.55 heading towards 3.00:1 which add massive amounts of load on the engine and heat.
