Can someone educate me on the fuel economy monitoring capabilities of the Quadzilla? I think that the gallon/trip is pretty self explanatory, but I don’t understand what the eco gauge is telling me. My truck did not have a mpg display originally, so I have always hand calculated just for curiosity. I have never recorded or tracked mileage other than a quick check at the filling station. I am curious about these features, as I am going to start playing with tunes and see how effecient I can make this monster. 

 

How accurate is the gallon/trip function? Can I rely on that data? It seems like it would be much more reliable and precise than the “pump until it clicks” meathod. 

 

What exactly is the eco gauge monitoring, and what does it tell us about fuel economy?

 

any advice on parameters to start with on building my own economy tune? 

I've done the flash. Nothing has changed no extra gauge. I've even selected the vehicle again. What am I missing?

You need to select the "V2 Quadzilla Only" vehicle from the list, not the "V2 QUADZILLA-ONLY" if that vehicle is in your list still. Thats the one that has the extra gauges. 

If testing goes well with this version of the base code it will be moved to the main line and the new sensors will be added to the V2 Dodge 1998-2002 vehicle profile.

Dude... That means I've got to rebuild my tunes... Not cool. Oh well. 

OR you can export your tunes, change the name of the vehicle selection in a text editor and reimport them. I've done it myself yesterday. 

Its completely incovenient, I understand. But I don't want to send out an update to everone when only like 3 people so far are trying this one out to see how it works. 

Just give your tunes a different name for the testing and leave the others in place. When we roll it out to everyone in a couple of weeks time you can go back to the previous profile and get all the tunes there still working properly. 

I have successfully flashed the box. @Me78569 the instructions in your flash thread are great! Made flashing the box super easy. I exported the tune and renamed in notepad. Everything is working great. I am pretty stoked about the new gauge. I have only had time to spin around the block with it, but it appears to be working correctly. I suspect that my offset is wrong, so I will be calibrating per the instructions above. 

 

@Quadzilla Power, would data logs of driving with the gauge be helpful in development? I would be happy to provide whatever I can to help refine. 

Can't import at all for some reason. Just tried that files are grayed out and do nothing.

Try this, create a new tune with your phone and export that out to the computer. It doesn't need to have anything set in it. 

On your computer, open up your recently exported tune and one that you want to import. 

Copy all of the settingsMap stuff from { to } and replace the tune you just created with the stuff you really want. You can change the profile name here too if you'd like. Email that to yourself and with the app open (but in the background) open the email and click on the imported .json file. It should give you the option to open with the QUadzilla app. 

Unless I'm misunderstanding and there is something else going on. 

 

To import, I exported to an email. Opened with notepad, changed the file name at the end to “Quadzilla Only”. Saved, emailed back to myself, hold on the attached file and clicked copy to iQuad. 

 

This is all from an iPhone, so I know it won’t be exactly the same for you Mike. But the rename part would be the same. 

@adamey1000 Data-logs would be helpful with longer ones over different time periods. Take one now and send it then one after a few days and send it, then one after you first tank of fuel and send that too. It would be good to see how the filtering is working over longer periods of time. 

Your perceptions on how it is working is probably even better feedback.

That's where everything stops. There is no option to open period...

If you save it to a file and then try to do an import does that work? 

I mean opening the iQuad app, then going to the custom tuning menu then clicking on the Import button. It should open up a file type browser with recent items that you can choose to import to the app.

Further explanation

Here is what I get... I've already uninstall and reinstalled the iQuad app...

 

 

Nevermind something change now the import is working from the iQuad app where it didn't last night... 

Crazy devices. I'm not sure what's going on with it. 

Google Drive... I sure wished the files were just saved directly to the SD card on the onboard memory of the device. When I manually uploaded the file to the SD card on my phone it works fine. Google Drive acts like the file doesn't exist but it does but Quadzilla can list it but not open it. Yeah, it shows up on the screen and can't import the tune. Again copy it to my little 16 GB SD card file works just fine and Quadzilla can see the edited file and imports like its suppose too. 

 

Never was a fan of exporting to cloud, download on the home PC, upload back to the cloud then import back into Quadzilla. Why not just save it to the storage of the device plug in the USB cable, edit directly on the device from the PC. Then just unplug the cord. Much simpler that all this uploading and downloading to make one file edit "1998.5 to 2002 Dodge" to "V2 Quadzilla Only".

I usually don't use the google drive method. I send it via email. I never though to send it using google drive, but that works for me. 

The hiccup I get is in the editing. I don't have a text editor that google drive will let me use to edit it so I can see where you have issues. 

From google drive though (the google drive app) I just click on the three dot menu next to the file, select "open with" option and it automatically opens in the app. 

 

Although a save to memory option would be nice. I'm not sure why it doesn't show up honestly.

Here is a data log from my drive home from work today. I am confident that my offset is wrong. I would love to be averaging 37mpg! I need some miles on the tank before I check the offset though. I just filled up this morning, so it shouldn’t be too long. 

iquad-2018-07-13-03.07.30.csv

First thing I would do is to make sure that your MPG Offset is set to 100%. I think it defaults to 90%. If you've already done that you are probably running pretty big injectors. Go ahead and do the method of running at tank at 100%, then dividing the actual gallons used by estimated gallons used then multiplying that by 100 to get the MPG offset percent that will correlate with your injectors. Some fine tuning may be necessary after that, but it should be pretty close. If the gallons per trip are accurate and the AVG MPG is still way off, let me know. 

 

It looks like I missed the part about setting to 100% to be able to check the offset. I have had the offset on 125%. Quick math, the gallon trip set and my odometer is in the ballpark of 20mpg right now. It looks like the MPG is coming down steadily. It is currently around 31. I will be resetting my offset to 100 and starting again. Can I get any useful information for my offset from having it set at 125% for the past week or so? I do want it to be as accurate as possible, so if I need to start over, I will. 

 

I may may be way off base, but it seems to me that the maximum mpg at coast going to 99.99mpg may be giving a false high reading on average mpg. It would seem to me that for a truck that is averaging 20mpg, 15 seconds at 99.99mpg while coasting would have a much greater positive impact on average mpg than 15 seconds at 5mpg under hard acceleration. Since the differential is so great on those two, couldn’t it be skewing the numbers high? Math was never one of my strengths though, so you will have to tell me. 

You will have to reset the AVG MPG after you get the MPG offset fixed.

You can do the maths to figure out how you need to adjust the MPG offset from 125%, but you really need a full tank at a particular offset before you change it otherwise it will skew the numbers. If you had it on 90%, but change it to 125 just recently you will probably want to start over. 

 

The instant MPG (ECO) going to 99.99 is because that is the biggest number that we are going to send back. The way it is calculated is because the fueling message sent to the VP44 at times when you're coasting is literally 0, which we believe means 0 fuel. When you divide the amount of distance you travelled by 0 your going to have a bad time. In math its infinite, in computers its NaN (which stands for Not a Number) and throws an error code and make everything die. So, when we see the fueling message of 0, we say you are getting 99.99 mpg at that instant. If we find out that the 0 fueling message means to still deliver a minimal amount of fuel then we will need to adjust it accordingly. 

 

I have had the offset at 125% for the whole tank so far, so that wouldn’t be an issue.

I assume that even at a 0 fuel command the engine is fueling at least at the idle level. But the amount of fuel that you are burning at that point probably is not significant enough to change the average. I will do a data log this evening on my drive home from work. I forgot to export the one from this morning. 

 

An app feature that would be handy for those with my kind of memory problems would be storing the last data log until the app connects to the iQuad again. I often forget to export the log after I shut down. If that log was stored locally in the app until the next start-up, I know it would be better for me. I am unsure how much storage that would demand though. It’s just frustrating to shut down, close the app, and THEN remember to export the data log.
