Ok thanks for the help

[Me78569]

Np once you get your starting point % figured out let us know and we can help build a tune from there

were you able to find a good starting % for your setup?

I haven't received my tuner should get it around next week 

[903Dodge]

When towing do you still want to stay around 17-21 degrees of timing at hwy?

 

I know you don't want any cruise timing adv.

[Me78569]

That depends on your rpm.  What RPM are you towing at?

[903Dodge]

2000 to 2200 I am pretty sure

[Me78569]

2k revs on a tow tune I would do ~17* 

2.5k revs on a tow tune I would do ~21*

 

[903Dodge]

Thanks.

Might take some time on Lvl 0 and watch how OEM timing works.  Might help you figure out what will work best for you.

 Hey guys,

 

Im seeking help in regards to my wiretap tunes not being "smooth" it almost like my wiretap comes on and off when in lvls 3-5. My canbus tun is very smooth throughout the rpm range. When in the upper lvls you can hear the exhaust note ramp up and down when the wiretap is on and off, even when WOT. I'm using Me78569 stock injector tune w/ boost scaling at 20. I have stock injectors and turbo. 

I thought my V2 Tuning may have just needed an update so i did that today and it still behaves the same way. I have attached a data log file below.

Verify your wiretap is connected well.  

 

Next drop your min pump tap fueling %.   Having min pump psi at 0 psi and min pump fuel % at %50 means that you are getting a min of 50 wiretap if you leave the line at high throttle.  

 

Try min pump tap %15 and pump low boost scale of 5 psi

@Me78569, @TFaoro, or anyone else who may be able to help: I just switched to a SO vp, and I have found that my daily driving tune needs to be tweaked to fit the new pump.  Everything was going fine until tonight, when the truck started acting up.  When revving, at the 1500 rpm point, the truck starts surging and popping, with plenty of white smoke.  I know this was a timing problem addressed before, so I am surprised to see it pop back up.  I am on the latest version of the Hard Fuel tune.  When the Quad is completely disconnected, the truck behaves normally again, so I'm hoping the issue is in my tuning.  Below I will post both my old HO pump tune and the new SO pump tune, in hopes someone can spot what I am missing.  

 

First, the old HO pump tune:

Power Levels: 11

 

Timing

Fuel Load Timing: 1*

Low PSI Timing Reduct: 2*

Timing Reduct Scaling: 100%

Light Throttle Timing Adv: 2

Light Throttle Timing Load Limit: 30

Timing vs rpm

1500: 15*

2000: 18*

2500: 22*

3000: 24*

Timing Max: 25*
 

Wiretap

Pump Stretch: 1800 us

TPS Pump max: 100%

TPS Pump Min: 15%

Minimum Pump Tap Fueling Percentage: 0%

Pump Low Boost Scale PSI: 2 psi

 

Boost Scaling: 25 psi

 

RPM Limit: 3300

 

Power Reduction: 70%

 

0 PSI %: 83

1 PSI %: 83

2 PSI %: 84

3 PSI %: 85

4 PSI %: 86

5 PSI %: 87

6 PSI %: 88

7 PSI %: 90

8 PSI %: 92

9 PSI %: 95

10 PSI %: 97

11 PSI %: 99

12 PSI %: 101

13 PSI %: 103

14 PSI %: 105

15 PSI %: 109

16 PSI %: 111

18 PSI %: 113

20 PSI %: 115

22 PSI %: 117

24 PSI %: 119

26 PSI %: 121

28 PSI %: 123

30 PSI %: 124

 

And now for the new SO pump tune:

Power Levels: 11

 

Timing

Fuel Load Timing: 1*

Low PSI Timing Reduct: 2*

Timing Reduct Scaling: 100%

Light Throttle Timing Adv: 2.5

Light Throttle Timing Load Limit: 30

Timing vs rpm

1500: 15*

2000: 18*

2500: 22*

3000: 24*

Timing Max: 25*
 

Wiretap

Pump Stretch: 1800 us

TPS Pump max: 100%

TPS Pump Min: 15%

Minimum Pump Tap Fueling Percentage: 0%

Pump Low Boost Scale PSI: 2 psi

 

Boost Scaling: 25 psi

 

RPM Limit: 3300

 

Power Reduction: 70%

 

0 PSI %: 86

1 PSI %: 87

2 PSI %: 88

3 PSI %: 89

4 PSI %: 90

5 PSI %: 91

6 PSI %: 92

7 PSI %: 93

8 PSI %: 94

9 PSI %: 95

10 PSI %: 97

11 PSI %: 99

12 PSI %: 101

13 PSI %: 103

14 PSI %: 105

15 PSI %: 109

16 PSI %: 111

18 PSI %: 113

20 PSI %: 115

22 PSI %: 117

24 PSI %: 119

26 PSI %: 121

28 PSI %: 123

30 PSI %: 124

 

So the new tune is basically the same as the old tune, with different CANBus settings and a 3* timing advance instead of 2*.  Any thoughts on why the truck would start missing? This tune worked fine for a few hours and then the truck started to act up.

Datalog datalog datalog.   In my experience white smoke and popping is due to too little timing.

 

Does this happen on the road?  Driving easy? Hard? 

 

You can try to mirror OEM timing 

 

1500 13*

2000 14*

2500 18*

3000 24*

3500 26*

This issue started after driving on a very long washboarded gravel road. At first it would pop in gear and free revving, but towards the end of the road when I unplugged it, it would pop once when in gear, not at all when it was slowly free revved, and really badly when it was quickly free revved. I will give OEM style timing a try and will do my best to get a data log of it

[Me78569]

My thought process on this issue

 

1. it was working without any changes ( so what changed?) 

2. why 1500 rpm?  ( oem timing is the low limit and quad 1500 setting is upper limit)  whats happening at that point? 

 

 

A data log would be very helpful so we can spot whats up. 

 

I would also drive around on lvl0 only for a bit and see if it happens still after a few days.  Drive it HARD.  At 1500rpm I would expect thew low limit setting of 8* to be enough to make it run without popping and smoking so I am not sure what is causing white smoke at such a low rpm.

 

 

Regardless I think I am headed up to denver friday to help a guy out, maybe we can meet up and see whats going on.  

[trreed]

Well there's no exciting data log to look at because the truck didn't do it today. Quadzilla plugged back in, same SO tune as above, and on level 3. So using Roadkill logic, that means it's fixed, right??  

Just kidding, I'll still keep an eye on it

[Me78569]

Trevor as we chatted about I owuld just keep and eye on things

 

The hard limits in place on the Quad are not low enough to cause white smoke at that low of an RPM.  Limits are 8* to 30* so at 1500 rpm you would need less than 8* to cause white smoke.

Could be a VP issue, I looked at a 2nd gen with a similar miss at 2000 rpms

[Meady24V]

Is there a link to the downloads for the old tunes? I want to flash the old tune and see if I still have the same issue. I had the ADR2_COMP before I flashed the V2. Don't want to go through the hassle of shipping it to quadzilla.
