Humm odd. Only seems to be an issue when timing is up near 20*? I've never had this happen on my long highway trips I will keep an eye out for it.

So one thing we know for 100%. since TPS is at 0 the quad is not sending a signal to the vp44. Does the miss come back when ac kicks off? Or does any load seem to kick it out of its funk?

So give me EXACT details on when this "lope" happens. As many sensor input values as possible That will help me figure out what is the cause of it.

You told me not to drive it hard until I retorque? Gotta get new intake gaskets tomorrow then I am off to the races... and yes I am bumping my rev limiter to 3700

hopefully the bugs are ironed out haha, I dont want to change anything else. Now we are just figuring out who things work with the ECM and our trucks.

Bigger your injectors are the more you need the control of the Quad.

if it aint broke dont fix it.

@TFaoro was here helping me get studs and springs and push rods in.

Fueling lower than stock is VERY helpful with bigger than stock injectors. HP wouldn't be lower as your injectors make up for it. By fueling we mean the actual fueling message to the VP44, think or the fueling message / commmand as a 0-100% for 0-235 hp on stock injectors. %50 = 117.5 hp etc Now you add bigger than stock injectors, the ecm doesn't know that the injectors flow more than stock so it is still commanding fueling like it would with stock size injectors. So rather than %50 = 117, %50 = 200 hp. Now move down to your offidle fueling, there becomes a point where even the lowest amount of throttle movement / change is too much and you get smoke. Our trucks in stock form really use about %25 - %85 of fueling, Using the quad to pull that %25 down to %15 or lower can give you a lot more fueling resolution. Again still the same power down low, but you are able to "recalibrate" the ecm tuning to match the larger flow rates of the bigger injectors.

Or at least gooder.

but the difference is big

sounds like they are bad to me. I'd be looking for a replacement.

Are you running a cruise timing of 2 now?

great info. What RPM was it missing at? overall 20* isn't that much depending on the rpm.

yea you would never get a 72 or 75 to spool as a single on a vp truck without some SERIOUS fuel.

You would hate life with a big single trying to tow. start with the small turbo and add a bigger one if you want it later.

lvl 1 is oem timing, whats happening is the screen is getting the wrong value ot show you. No real issue, just a minor bug.

on lvl 0? it jumps?

I'd do the t3 housing personally. As for injectors I would talk with @dieselautopower about it. They can get you set.

I would like to see over 12.4v+ after sitting with a full charge but @Mopar1973Man would know better. I would have your batteries load tested if you are concerned

I'd do a 62 sxe and some 7 x .010's

6 cyl mode just sounds like a normal cummins running at 1200-1300 rpm.

You will like it, if you really wanna speed up the warmup process get a EB installed. A few minutes on 3 cyl mode with the eb on creates some serious heat

Having to "figure out" the differences is hard. @Carbur8tr From what I have seen my MPG seems to be best when my canbus tuning is aggressive enough to to get me off the line without going too deep into the throttle, but avoid smoke. I have a very light haze under heavy accel now. However you should only need as much fuel as you need to keep speed, canbus % shouldn't matter in the end. Now that Cruise timing is %100 on it's own I can also say that canbus % shouldn't matter, it would have before, but the change this week removes oem timing out of the mix. I would be very curious to hear your findings from this week forward. I think that your Timing is going to need to be less aggressive across the board by 1*-2*. I would spend some time at 65 mph moving timing up and down at a given speed and see what causes EGT's to come down. Using The cruise timing setting should allow you to do this pretty easy.

in the vehicle section on the Iquad unit what do you have? Ensure you choose the V2 vehicle out of the list. that's what tells the phone what tuning parameters to use.
