Here is what is happening for my truck. Any power level above ZERO and any tune including DEFAULT tune will do this. ZERO level is clean and smooth no issues. Reflashed my Quadzilla with the current tune and even dumped my iQuad App and reinstalled.

I am gonna move this into it's own thread.  

I don't believe mine does that, I think I would of definitely noticed it but who knows. I'll check next time I drive the truck. 

it only happened sub %5 throttle input

Nick and Mike - My truck sounded just like that, but much, much quieter at just 1% throttle input.  I had to be in a dead quiet area to hear it at all.  Same issue you're looking for?

 

Bigger the injectors the worse it gets. Stock you can't hear it or feel it. The 75HP VCOs now really produce a nasty miss. Checked a few time 0 level is clean but any level above 0 will prosuce the problem.

Hey Mike, 

Are you running the default tune or a custom tune? Could it be case of going in and out of "tuning" with the timing? Do  you have a data-log of it? 

I noticed the same thing I figured it was the quad and the ECM fighting for contol

Mike I have bigger injectors than you. But mine is very quiet, so I'm currently ignoring it. 

Does this happen above 1000 rpm?

No. Mine is near idle range. Ill try and do a video of the display values.

test for me and see if it goes away once you top 1000 rpm.  There is a "smoothing" function in place to average the fueling below 1000 rpm if you do throttle input.  I am thinking maybe this might be causing the issues. 

 

 

Another one of those fix one thing break another.

Pretty sure ill check.

alright,

 

The code says this. 

 

If Canbus Fuel % is < %6 & Mph is under 1 and rpm are below 900

 

Then take (input fueling + Quadzilla fueling) and  / 2

 

 

Can you just take " and /2 " out of equation, or should I 

that would double the fuel and cause a brief run away or touchy throttle situtation.    The above functions averages what hte ecm wants and what the users tune wants right off idle to prevent stalling.

@Mopar1973Man

 

Can you try this flash and see if it is better?  I have disabled the smoothing function below 900 rpm.  I think that may be causing the issue.

Let try to data log again. The last one I email mailed to myself disappeared into thin air.

 

I can't run any custom tune now it will crash the iQuad App. As before the crash problem it did matter what tune you used it was the same problem on any level above ZERO.

That is weird. Did you grab the latest binary from app store? or are you on a previous version of the app? 

I figured out last night that after you apply the tune you wait for a minute or so you should be able to apply a change in power level. 

-Thanks again,

Try these steps,  

 

Open the iquad app to the tune menu, Click the home button on the phone -> apps-> downloads _> click the tune in question and load it into iquad app.

Doesn't matter. I can shut down wait 30 seconds. Start everything up. wait another 30 second touch power level up or down and it crashes the iQuad app. Now the recovery method I found to get back to Default tune is to shut down the crashed app. Quickly fire up the app again go in and change to default tune. Shut down the app again after waiting about 30-60 second for it to bluetooth over. Then when you fire back up it works again. 

 

Also noticed that any custom tune the app has serious trouble making connection. Some time its 3-4 try before it hooks up on custom tunes. But if you flip back to DEFAULT then it nearly instantly it pops right up so there is nasty code hanging the app up.

Does nothing the tune never shows up in the list. If you repeat with the same name it says the tune already exist but nothing is in the tune list.

It has been that way for a while now too apparently, not just on the latest version of the app.
