Can other people reproduce this issue?  I can sit at 1100 all day long and it just purrs away.  

 

Let me know

I can't seem to feel any sputter, but I do have an issue with quad crashing for no reason not even touching any buttons. Keeps showing this

And even if I unpair it from quad it still does it, like the app itself is caput. I tried it with s6 that is dedicated to quad and after not having any luck used s5 my phone and same thing, after a while I got the s5 to work, and later decided to try s6 and same thing so then switched back to s5 and s5 don't want to work so another 10 min later got the s5 to work. I think problem is in apk because before this last update it only crashed when switching levels too soon and now I'll be driving and not even touching anything and it can stop working, so whatever happened in last update whether it's flash or apk something got screwed up. I know others having same problems. Read reviews in app store. Using 1998-2002 v2 in vehicle selection.

I was having a similar issue with my Samsung galaxy tab. I turned it to airplane mode with Bluetooth enabled and it has seemed to help quite a bit. Now my app only freezes once a week or so. A simple restart of the device and reconnecting it works for me. Give that a shot and see if you have any improvements.

come to think of it my device is also in airplane mode.  I don't seem to have issues with the app itself, but I know others do.

Didn't even think of airplane mode, will give it a try. Thanks.

When you say restart, just the app or do you restart phone. I tried everything even shut the truck off and when it didn't help I unplugged quad from battery and it still didn't help. Aventualy it started to work again.

I haven't been able to mimic the hard shudder like Mike has but I do have a small lope at around 950 rpm with 2% throttle.  Nick I have a video that I will email you here in a bit. 

 

I still have a slight bucking issue.  It's always around 1150-1250 rpm at very light throttle input and low boost just maintaining speed.  Say I'm cruising along at 55mph and I approach a gradual incline and don't give it throttle, when the rpm drops into the rpm range mentioned above it will start to buck.  It will stop once it down shifts or the second I give it more throttle.  I have been all over the place with timing settings and it made no difference which is why I asked earlier how the quad managed timing below the 1500 rpm setting.   It does seem that all of us with this issue has larger injectors.

If you could data log the bucking so I can see what is actually happening in the data.

Here is the video. Sadly the app crashed as I was trying to export the data log on this.  This may be what Mike is experiencing but his seemed more harsh in his video.

Finally got it added

Here is a short data log of what's in the video. Couldn't get it to maintain it for as long as I did in the video but it does it several times throughout this log

Whenever your app crashes, please push the report button. It helps us figure out why its crashing. 

-thanks again,

I do it when it gives me the option to but sometimes it just locks up or shuts down without giving me the report option.

I'm noticing this issue most so at higher fuel temperatures than at cooler temperatures. When I'm seeing 130 to 140*F of fuel temperature it tends to show up better. Cooler fuel temperatures tend to mask it. I've been playing to find all the variables that seem to make this possible.

950 rpm is where the Quad is starting to take over.

Here is the data log of the bucking.  Happened right around 1100 rpm.  It's the 10 seconds or so right before the 3 throttle blips. 

iQuad-2017-08-14-02.24.54-1659283566.csv

What line approx are you referring to?

Sorry Nick, out running around and didn't actually look at the file before I uploaded it.  I did 3 quick throttle blips right after it did it.  Not full throttle blips as I was in traffic but probably quick half throttle blips and then exported the data log right afterwards.  Got to be in the last 30 seconds on the log maybe a little longer.

Yeah just had a chance to look at it.  I think 8226 to 8278.  That was a lot wider data log than I was expecting,  my throttle blips were huge lol.  What's the sample rate of the datalogs?

1/3 seconds as data comes in. 

 

Your lope at 950 is just he quad turning on and off.  950 is the limit for the quadzilla sending the commands. 

 

Your surge issue I am not sure about.  Timing and fueling looks spot on for the oem data logs I have.   How noticeable is it?

Pretty noticeable.  Stronger as it gets lower in rpm.  This could be a mechanical issue I'm thinking.  Maybe the trans is trying to shift out of gear or unlock the convertor?  This is typically lugging around in 3 or 4th with the TC locked.  Once the TC unlocks or it down shifts the bucking goes away, but that could be because the rpm goes back up as well.

bucking is going to occur too low in the rpm range.

 

 

To be clear this does not happen on lvl 0?

Problem is I feel it on a manual 5 speed transmission too. There is no torque converter clutch to unlock for me. Normally feel it around 25-30 MPH range which most of the small town I travel are 25 MPH city speed limit. Closer I get to Ontario the more you get normal 35 MPH speed limits but traffic hold me down in the 30 MPH bracket and its felt again. 

 

@NoMercy Z06 try switching to ZERO level and see if it goes away. If so the whole problem is in the Quadzilla.

Already ahead of you.  Just made a quick little run to a small valley were this happens every time, first pass was on zero, second and third pass was on 3.  I didn't feel any surging on 0 but did on 3 although it was very light.  Here's the log.

Does the quad do any apps fooling?

Nope the quadzilla has zero code in it to write to the ecm.  One way communication only ecm > quad > vp44.

 

I'll look over the log when I get home.  It would be awesome if you could give me lines to start on for each run so I can build graphs.

 

 

One more question.  Tc locked low rpm, when the shudder happens if you lay into it the shudder goes away right away?   Also what is your tune starting point?  I am sure you posted it but my memory is like a gold fish.

I cleared the data log right before I made this so there shouldn't be much to look at.  I downloaded this while on the road so I didn't get a chance to look at it but next time I'll try to get you a starting point before I upload the log.  

 

If I lay into it it down shifts right away and the shutter disappears instantly. But it also disappears if I ease into the throttle pretty much instantly as well.  

 

I'm not running tap so here is where my tune is

 

Load offset 1*

Low psi reduct 3*

Scaling 100%

Light throttle adv 0*

Load limit 35 psi

 

1500  14.5*  been as high as 16 in testing 

2000  19*

2500  23*

3000 25*

Max  27*

 

0- 94

1- 94

2- 95

3- 96

4- 97

5- 99

6- 101

7- 103

8- 105

9- 107

10- 109

11- 111

12- 113

13- 115

14- 117

15- 119

16- 121

18- 123

Up by 2 the rest of the way. 

 

 

On my economy tune I started the can bus fueling at 85 and if I blip the throttle from idle say while pulling out of a parking spot the engine would die.  If I go any lower than 94 on the tune above it will die as well.  This may be do too the 950rpm switch over and it can't react fast enough?   Again this is if I just blip the throttle quickly.
