Depending on the device you will notice the app freeze when the CSV gets too big. That limit seems to vary per device.

Report the freeze when it asks.

Our trucks didn't have Cats from the factory Hide the tuner so they won't see it and you will be fine, the obd is none the wiser. Do you have stock injectors?

forgot the sarasm light. Sucks no doubt.

post your modes and we can help you with a tune that's clean. I can pass a sniffer with wiretap now days....and I am at 6500' altitude.

glad we were able to help you ruin your TC lol. Get some video's of lvl 0 vs lvl 3 when you get a chance very curious to see how it does.

I would encourage you to watch OEM fueling on lvl 0 to see how the ecm fuels. in short, Offidle: it iwll jump fueling to ~2800 at WOT midrange it will pull fuel some upper end it will start to add fuel back up until ~3600 is hit So setting canbus at %112 will give you a max of ~4000 ( 3600 * 1.12 = 4032) but it will only do so when the ecm is asking for max fuel up top. If you want more meat under the curve you can ask for ~125% of fueling to beef up the midrange fueling. If you want to dd on lvl 3 then tune your canbus to be nice for daily then if you want to race jump up to lvl 5 with wiretap with the below Use these wiretap settings. That will make it so you always get %25 wiretap or more if you go WOT. That should lit the turbo and get you moving. Smoke will happen however, but since it is a race only thing it's fine. So DD = canbus fueling Race = canbus + wiretap

Popping up top means you need to back timing down. Make note of what epm it is popping at and drop timing by 1* Little laggy will be the nature of the best if you want it to run clean. You can only tune so much before you run into issues with mechanical injectors. We cannot adjust injection pressure on our trucks. I would suggest driving on the tune as it is now for a few days and see if your driving style gets used to it. 126% should absolutely Max out canbus. It only really takes 112% at wot to Max out fueling. If egts are still an issues I'd drop wiretap more, say 1200. You have a ton of mechanical fuel for that turbo.

What turbo specifically do you have? How did the changes do?

What mods do you have? The Hx35 can handle a good bit of fuel over stock before it starts to get puched out of it's map. I would just rebuild the current turbo and call it a day. The Hx35 can easily handle ~325 hp worth of fuel.

Yep

No worries you'll get it. Hardfuel tune just tries to extend canbus fueling to 3500 rpm the Standard fuel tune doesn't. That's the only difference I was speaking of. Don't be discouraged, you'll get it. Let us know how it goes. Bumping timing in the 2k+ region will also help egts. Increase in 1* increments until you get surging then pull back by .5* until happy.

Sorry I was talking to diesel future not you, hardfuel and standard fuel base tunes are the same below 3200 rpm, you are messing with the custom tuning on top of the base tune. You made great progress. Good job for going out and doing that! Your canbus tuning looks good. Turn your wiretap down to 1400 and report back. You have a ton of mechanical fuel so you don't need much wiretap to make good power. Your timing curve looks ok. I know big injector trucks can't run as much timing so you might be a ok. Might bump 2k+ by 1* and see how it runs. I would expect Max timing for you to be 24*-25* Again kiddos for jumping in.

Zippo difference between the two tunes until 3200 rpm. Lope is not related to the quadzilla as it does it without to input.

Under the garage door opener section there are 2 plastic tabs just press them and pull back on the hole thing.

with your injectors I would expect you to be happy with valet mode at %75-%85 of oem fuel. start playing with it and it will start to make sense, there is nothing complex about it, it's just a lot to understand at once.

No in your custom tuning menu create a tune, in that tune you will see "valet mode power" that setting applies to lvl 1 of the Quadzilla and it allows you to set fueling between 0% and %100 of OEM. So what you need to do is figure out your starting %. So go out set valet mode to %80 and stomp on it with the Quadzilla set to lvl 1. Is it smokey still? If so drop the Valet mode power by 5% and try again, is it slow, then up the valet mode power by %1. Do this until you find a good spot for your tune to start. Once are happy with how the truck takes off and smoke levels then you will start your canbus tuning at that %. Until you know your Start % you can't do much. You will just be blindly guessing. As for lope the quad is not adjusting fueling at idle, that is a result of your fueling setup. The Quadzilla will not change idle state behavor.

ccd bus means the overhead cannot read any incoming CCd message. If hte cluster doesn't show it then it is likely a wiring issue in the overhead.

Use valet mode power to find your starting point. set the Quad to lvl 1, then set valet mode power at 75%. From a stop stomp on it, It is slow? If so increase the % until you are happy with the trade off of smoke vs power. Once you have a starting % build the rest of the tune from there. Your timing will have to be ~2* lower at 2k - max to not pop

Test your sensor. I would assume your sensor is old and it is not able to read under 4 psi.

That's what the ECM is likely seeing as sensor input. What year truck is it? It's a sensor input so if the sensor is incorrect then the reading is incorrect. 0-2 psi is normal 4 psi is high.
