Quadzilla Power

As I drive a stick, that is something that I never thought of. I hope that works out well for you.

This forum really is fantastic. We love these guys over here. Also, just as an FYI, kzimmer really did have to do a lot of tweaks to the operating system on his stereo unit to get it to work. If you are pretty tech savvy you should be able to get it to work. We are not Android Auto compatible so you might have to put a different version of the OS on there.

Turns out both ME and I were correct, but for different reasons. Apparently, the map will top out about 36 psi, but if you make less than that you can definitely benefit from dropping the boost scale lower.

No. You will only get a percentage of the full fueling. It will be almost full fueling, but not quite. If your max boost is at 35psi, then dropping the boost scale to match is a pretty good idea. It may even bump up your max boost a little. It will compress the scale down a little bit and some report that it feels like a more sensitive throttle response. And I just stepped on ME's toes because he said the exact opposite. Do I have this wrong Quadzilla's Skunkworks engineer?

Our default that seems to match pretty well with what the older ADR2_1000 tune did starts at 105 and grows exponentially from there. (kind of a guess of the exponents) but here are the settings we are putting out there for default stock trucks that nearly match the ADR2_1000 feel: 0 PSI %: 105 1 PSI %: 107 2 PSI %: 109 3 PSI %: 111 4 PSI %: 113 5 PSI %: 115 6 PSI %: 118 7 PSI %: 121 8 PSI %: 124 9 PSI %: 127 10 PSI %: 130 11 PSI %: 134 12 PSI %: 138 13 PSI %: 142 14 PSI %: 146 15 PSI %: 150 16 PSI %: 150 18 PSI %: 150 20 PSI %: 150 22 PSI %: 150 24 PSI %: 150 26 PSI %: 150 28 PSI %: 150 30 PSI %: 150

I have actually been trying to find out a good number for the duration of time for a 4095 CAN bus message fueling stroke on the VP44. The results are not encouraging. It seems that the pumps are electronically tuned based off their actual output. Stronger pumps will actually decrease the time of the stroke to match the mm3 number printed on the pump where weaker pumps will increase the time to match the mm3 printed on the labels. This means that when we stretch that signal you will actually get a lot more fuel on a stronger pump than on a weaker pump. There is no real correlation between fuel delivered and time that is consistent across pumps. Its going to make estimated fuel usage when stretching really hard to figure out. To be honest, I don't even know what the average stroke duration is to be able to get a best estimate. If anybody out there knows this I would love to have that information.

Well, Its been a while since I checked this. We got TJs box in and did work with him even without knowing he posted this in the forum, so there is that. Honestly, we don't know what happened to his box. It is definitely weird and not a normal failure mode thing. Love all the help with the tunes by the way. You guys are great!

Doh!

Me78569 may be on to something though. The code in the Adrenaline sets the target RPM range and then slowly increases the fuel until it reaches that RPM and then constantly adjusts it so that it stays near 1200 RPM. There is a maximum fueling level that it will increase to and the 950 may be at that maximum fueling level until the truck warms up. Do you have a datalog of the warm-up? that would be helpful in looking at what the fueling message is.

Seriously Above and Beyond. Much appreciation for you Nick. I really hope you don't get inundated by one-off requests now. It was super nice of you to do this for Scott. His ride is pretty cool, at least in videos. -Thanks again,

Was there no other message regardging the state of the drive? It might have said something like: "Cannot Use External Storage: xxxx" where xxxx is the reason it can't?

Have you downloaded the Beta version and tested it for freezing? I really think that it fixes most of the issues that caused the "freezing". http://quadzillatech.com/TunesDownloads/AndroidApp/IQUAD_Android_app-release(1.9.40(56)).apk If it doesn't fix it for you let me know. I like the idea of having a title bar with the "name" of the currently selected tune somewhere on the screen. I will have to look into it. As it displaces stuff on the screen, it may cause all sorts of headaches and issues and might be cost prohibitive. -thanks again,

While we are adding the KPH, any other parameters that you want to see options for in metric? kPa for the boost or Centigrade for the ECT and EGT perhaps (I'm not sure this one is feasible frankly)?

Really, like the description says, the only update is to the default power levels on the CAN bus. Using the the latest 2.5 tunes (2.5.2) and with custom tuning you literally won't see anything different. The reason for the rev of the number to 2.6.x is because we are thinking of adding KPH for our friends in the Great White North to the vehicle profile as an additional sensor and any modification to the vehicle profile needs a revision update. About the freezing, that should come with the latest version of the app. I updated the .apk link here for that too. Here is another link to it: http://quadzillatech.com/TunesDownloads/AndroidApp/IQUAD_Android_app-release(1.9.40(56)).apk To our iPhone using friends. Do you see a need to see the progress bar? or is the spinning wheel good enough for y'all?

There is nothing that I've found that says any special permissions are required. However, the total size of the "cache" section would need to increase to account for the data-log. The exported custom tunes are less than 1 kB so they shouldn't really require anything extra. OK, I did a special build for you that doesn't use the createTempFile file call and instead creates a normal file in the "external" directory. Basically, all the external means is that it isn't hidden and you should be able to navigate to the file. Try this file: http://quadzillatech.com/TunesDownloads/AndroidApp/IQUAD_ANDROID_app-release(SPECIAL-BETA).apk Like I said before, this is a special one-off build. If you get a warning saying failed to export or something else, tell me what it says. It may help identify what's going on. The files were created for me in the following directory: Internal Storage>Android>data>com.quadzillapower.iQuad>files I tried it on two different devices and they were created in the same area.

well, I tried and got a permission denied error. I am looking to see if I can fix it real quick or if I need to get the developer involved.

I'm seeing if I can build a version for you that doesn't use the external memory call and just uses the getCacheDir() call instead of the getExternalCacheDir() call. Try it with the SD card as well to see if that fixes it.

I did listen to that song today and did find a disturbing lack of cowbell. I could have sworn it was more prominent in there. Regarding the createTempFile call, Here is the exact call: File file = File.createTempFile(filename, ".json", this.getExternalCacheDir()); This is the call for the "export tune" call. I think you are probably getting an error on the getExternalCacheDir() call. It is built in to the API for Android and should be used with Android 4.2 or higher. It appears that no permissions are required starting in Android 4.4 (KitKat) to use files in the directory. I do have a request out to the developer to see if an external SD card is required, but it doesn't look like it is.

I have had that happen to me once. I still don't know what caused it, but its been fine ever since then.

Good deal. I didn't get it uploaded to mopar1973man.com yesterday but will try to get it uploaded today.

I got another drop on Thursday that looks very promising. I'm just doing some testing on it today and tomorrow then we will release it for Beta testing and then when it looks good we will push it out. Of course, you can try the version this version if you are adventurous: http://quadzillatech.com/TunesDownloads/AndroidApp/IQUAD_Android_app-release(1.9.40(56)).apk I will try to get it uploaded here today too.

I know you checked the main wiring harness plug, how about the 4-pin Deutsch connector to the iQuadBT to make sure that all the wires in that are good and solid? Some of them have been over-crimped. Hopefully you don't have one of those, but it may account for the issues that you are seeing.

I am going to get rid of the 2.4 vehicle profile here soon so it is a great idea to update to the latest version of the code.

That is totally strange. It really doesn't make any sense either, but stuff doesn't always make sense. When you do get a custom tune to load, does it load all the parameters? or does it leave a bunch out?

It definitely sounds like it is a different problem. Have you inspected the plug? Sometimes they can have issues.
