Before my torque converter started slipping, I was getting 20-21 mpg (hand calculated) with timing advance set to 8, pump stretch set to 1800, both maxes at 100 and mins at 25, just like you. However, my boost scale is set to 21 since I don't have a J-hook. That was at PL 7 too, not 5. Mods are in my sig.

 

yea seems to run smooth with the 100 and the 25s, i may try the boost scale down lower thanks

 

i just run the comp tune. i use pl1 for the street and then when i jump on the highway i put it on pl8. i get 16 mixed driving and 21on the highway cruising at bout 65 or less.

 

z.a.p and halycon are you guys runnin stock trannies?

 

Was, till the Adrenaline helped me fry it It's still holding in there for now, but barely. I'm gathering stuff for a manual swap right now...

 

Since I put my quad adr in I have been driving it pretty hard, so mileage is crap. Its either level 10 or 0 for me. I think with a set of 150hp injectors quad adr and stock hy35 turbo its way to much fuel for the size of turbo and the air it flows...

I do see 500 miles with the quad adr set to 0 though................ which prob deosnt help the thread

 

Man even 16 mpg would be awesome for me.. When i sent in my box i was getting about 13mpg and even now with the box i just filled up today with 334 miles on my 32g tank... im thinking my VP is about to s**t out. hahaha. darn.

 

btw. with the quad adr set on lvl 1 that is their max milage tune. so i would leave it on 1 rather than 0 and see if that helps any

 

ok thanks Ill try that on this tank!

I use to see 480 miles to a tank with no tuner and just a stock straight pipe exhaust. Now with a BHAF the quad adr. and a 5in turbo back i'm gettin worse mileage now I'm seein like 360. I normally run around on level 1, but today got to thinkin I'd mess around with the custom tunning so thats what got me thinkin about it.

 

Best I got on a long trip (from Eastern to Western Washington) was 26 mpg, hand calculated. I have what is in my sig. This was on a 70* day, cruise set at 60 most of the time and on summer fuel. AND I have the taller ratio, 3.55's i think.

 

what was the quad set on?

 

Oops, I did forget that. I had it set on PL 01.

 

no problem fire1515 just wondering. sounds like you had everything in ur favor :thumbsup:

 

Ya, I did. Haven't been able to duplicate since. But locally I can still see 20 and that is a good mix of driving. When I got 26, I was in some mauntainous areas. I would love to run across some flatlands for 600 miles and see what I get. arty018:

 

sweet thanks for the info halycon i will let yall know if it makes much difference

 

Once I get my tranny swapped out for a manual, I'll put up my findings too. Definitely let us know! :thumbsup:

 

subscribed..... theres some good stuff here

 

bumb for more info.. i know there are more quadzillas out there, more info

 

Haylcon,
Thank you!
I punched in that tune and I'm running it on level 3 because I don't have an airdog yet and I am seeing imediate improvement. I know most say that the overhead display of instant and average mileage are way off but mine has always been +/- 1mpg when I hand calculate since I've owned the truck. So that being said I was runnin down the interstate tonight and before setting my cruise at 75 it would read 11 or 12 consistently, well after inputing your tune I can run 75 and its reading out 17 to 19. I am goin to hold my breathe until I run through this tank though just to hand check the numbers, but hey this is awesome thanks for the advice!
Josh

 

No prob man, glad it's working well for ya! :thumbsup:

 

wouldn't PL1 give the best fuel mileage no matter what? As it is only timing, and no fueling mods?

 

Nope, I definitely do not get the best mileage on PL1. I believe it has something to do with load factor... Here's my theory: When you're on higher power levels, you don't have to hold the pedal down as far in order to keep the truck at a certain speed. Since the pedal isn't down as far, the load calculated by the computer is less and it commands less fuel to be injected. The offset between pedal positions is enough to overcompensate for the extra fuel that was commanded by the Adrenaline. I could be wrong and I'd love to figure that out for sure. Just an idea!

Also keep in mind that in many states and areas of the nation, now is not the time to R&D mileage.... in the cold weather and winter fuel.

My numbers were on summer fuel. Good point for sure :thumbsup:

Which tune ?

I am running pl08 most of time
See 20mpg why hand calc
See 15 mainly city/suburbs

Think I am down around 1mpg since my juice

Curious on any tunes that may help increase - I guess I should try
Lower levels also *shrug*

Go into the custom tuning menu and set the following to these values:

Pump stretch: 1800 us
Timing advance: 8*
Can max and pump max: 100
Can min and pump min: 25
Boost scale: <highest boost you hit with your specific turbo>

 

Also keep in mind that in many states and areas of the nation, now is not the time to R&D mileage.... in the cold weather and winter fuel.

 

halycon, i agree completely, my best mileage was on pl10 before my clutch started slipping, along with grandma driving

 

No I totally agree !! Hence always run on higher levels




cool thx - can you do a basic explanation on each one ? How is it diff to stock tunes ?
Thx

Yeah, just like Double-O-C said, just drive like a grandma... it's hard haha, but if you can do it you'll get great mileage. I actually get best on PL 7 though, it seems.

Here's an explanation of the tuning parameters... I take no credit for this- it comes from another thread, HERE:


Pump Stretch.

This will make the biggest difference in overall power and smoke. This is the amount of time the injector is actually opened and spraying fuel into the cylinder. I have this set pretty low on the 1000 tune that I sent you. The COMP file is set to 1800. More than 1800 creates more torque and a lot more smoke but, actually makes less power on the upper end based on all the trucks I have had on the dyno. This is where the COMP file is set to. Feel free to run it to 2400 anytime you want lots of low end power and smoke but, realize you are giving power up on the top.

This does not mean you will get this amount of fuel all the time. There is a map, in percentages based off of this number as the maximum. Beyond that the map is also scaled by the TPS. So even if the map commands 100% but, you are at 50% throttle you will be getting 50% of the max stretch. If the map calls for 25% and you are at 50% TPS you will be getting 12.5% of the max stretch.


TPS MIN. For both CAN and Pump fueling.
(from quad)
This has changed.


This allows you to set what TPS% the box starts fueling. While the obvious answer is to set this at 0% that is really too soon. Watch your TPS% while driving and you will quickly see that the TPS% is not linear and on average you are using 25-30% TPS even under the lightest throttle conditions.

The latest tunes have this set at 30%. If you set it lower than that it becomes more aggressive but, it can also cause some surge issues because it fuels so soon.

If you want a more aggressive pedal I recommend you lower the TPS MAX parameter and lower it to 60-70% for a really aggressive pedal feel.


You have to be somewhat careful with this or you will be fueling way too much at light throttle. This is set to 0% on the tune I sent out.


TPS MAX. Both CAN and Pump Stretch.

This allows you to determine what throttle position you will see max fueling at. It also re-scales the entire map based on what you select. This is set to 100% on tunes I sent out. This means that you will not get 100% of the map unless you are at 100% TPS. If you set this at 80% TPS that means you will get 100% of the fueling at 80% TPS. It also means that 80%=100% and the map is scaled between 0% and 80% but, on a 0-100 scale. In other words the map moves in increments of .8% instead of 1%.

This can be really useful for those that drive light but, want power on tap earlier in the pedal but, not necessarily right off idle.


Timing MAX

Sort of goes without saying. 0 means we do not add any timing. 10deg means if the map calls for 100% you will get 10deg added over stock.

I never go over 7.5%. In my opinion that is more than plenty. If you are going for only mileage and are going to be easy you can use 10 deg and it should be great for mileage. The problem is that under much boost it could easily cause headgasket damage.


Boost Scaling.

This function is more of a smoothing function of the map. There are 20 positions that this function controls. Think of it at columns. Until boost equals a certain amount, then it is in a certain column. It takes more or less boost to move to different columns.

So if you set this to 20, then each column is changed by 1psi. If you scale it to 40psi then every 2psi it changes.

While this can make things more or less responsive or smooth it out slightly it does not make huge differences because not necessarily every column is more or less aggressive than the next. There have been maps in the past and there will be maps in the future where they will be more boost reliant. For now we do not rely on boost that much other than as this scaling function.
-Thanks To RacerRon

--------------------------------
TIPS:

Things that will make more smoke:
Lowering the Boost scale down
Lowering TPS MIN on both CAN and for the PUMP
Lowering TPS MAX on both CAN and PUMP
Raising MAX PUMP STRETCH
Lowering MAX TIMING
Lowering TIMING SCALE

All those things in one way or another will make more smoke. Raising the pump stretch is the simplest way to do it.

Stacking With a Timing Module:
You can set the MAX timing advance to 0 or you can set the timing scaling to 0%.
Either way you get 0 timing.

lower the scaling, the softer the curve:
If you turn the MAX up, and the curve down, you will get more timing down low then the factory settings with the MAX timing ending up about the same.
If you turn the max up to 10deg MAP. and then scale it by 80% you will end up with 2.4 deg advance in that same exact map spot and a MAX of 8deg at WOT.
100% scaling gives you the most aggressive map for a given MAX timing value.

Thanks !!!!
Guessing you only get custom tuning on a custom downloaded tune ? Just went to my settings and see no customizations apart from boost get levels etc ....

 

Nope, you can customize any tune. There should always be a factory tune on there, but you can customize that and save it as either tune 1 or tune 2.

 

go to menu, custom tuning, tuning parameters, change them to what tune you want, go to the bottom to save, save under tune one or two, load tune and load the one u saved it to, then go back to ur main screen with the gauges and it should say T1 or T2 at the bottom... if not then your still on the factory tune :thumbsup:

 

Guessing this is on computer ? Or on pulse ? I have the iquad ....

 

Download the latest iquad update and custom tuning is enabled.

 

Awesome !! Got it.
Thought I had done this - but it was just the default truck profile I updated to 1.4.

Now I updated the IQUAD from the appstore - have it enabled thx
:thumbsup:

 

yea thats for the pulse
