Quadzilla Shudder light throttle

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 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.

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?

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

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.

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 :sofa:

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.

This means you have the wrong vehicle profile selected for the tune.   Your eco tune needs to be in the vehicle profile "1998-2002 v2 2.5"

 

You had uploaded the eco tune using a different profile that was for the testing stuff, I fixed that so other people could use your tune.  Since you are running V2 now you have to use the v2 vehicle profile.

You have to make sure that the tune that you are downloading and loading up are for the vehicle profile you have currently selected. otherwise, it will load up for the different vehicle profile and not for the current one. you could probably find it if you switched vehicle profiles, but it may have been corrupted during the save.

@Mopar1973Man @trreed @silverdodge @anyone else having these types of issues right offidle / low tps.  Can you guys give this flash a try.  I have rewrote the way the ECM and Quadzilla trade off control. The ecm will handle fueling / timing sub 950 rpm.  There is no longer a smoothing function in place to try and prevent stalling, I have handled that back to the ECM for control.  

ADRV2.exe

 

Let me know if it still does weird things, also let me know if you notice a significant increase in smoke right off idle.
