The datalog showed max boost of ~30 psi at 2500+ rpm. Boost didnt start to come up from 0 until 1800 rpms. I dont think the map sensor is working right. I would expect 50+ psi on a %50 tps pull witht he old tune

Setting to 150% from 0-30 psi will give you %100 duration. It will likely give you that at %40 throttle. Issue is there is no %105 duration. So once you max out duration there is no where to go. Most guys dont want their tune to just fuel 100% when they snap the throttle to wot. Rpms and boost should both be at the right place in the map to command peak duration. You can tune how you like. If you dont see %100 duration at %150 across the board then you have something else up. The quad is just mutplying the stock fueling message A stock truck at 15 psi at 2000 rpm with a canbus setting of %120 will max duration. Like i said before you map sensor looks lazy and your ecm is not fueling like a normal truck. You tune wasnt great to starts but i am nearly positive something else is up.

If you want more offidle fuel adjust your canbus curve until you are happy, i sound like a broken record but wiretap is really good at 2500+ rpm canbus is good offidle Tune the canbus curve so at wot you are happy with torque. When you are done with that then add in wiretap to fill the voids

You might also set your min wiretap % down to 0 from 50. You have more than enough injector to not need wiretap to make up the meat of your power. Wiretap is really good at extending fueling at 2500+ rpm. Canbus fuel + injectors is good at making the meat of the curve.

Yep set your pump low scale psi to 10 psi to keep wiretap off until that psi. Leave the tps settings 0 for min and 100 for max. That just shifts the wiretap map up related to psi but still leaves a smooth curve that is not compressed.

vehicle profile selected is what defines what sensors are able to be choosen. MAke sure you setup your vehicle correct.

drag up from the bottom and click and drag the sensor data you want to move in place. Here is the Iquad App user manual. http://quadzillapower.com/content/Forms/Instructions/iQuad_Instructions.pdf

the reason we dont cut canbus on levels 4-xx is a good tune shouldnt need canbus to be cut. canbus fuelig should be smooth and easily controllable with the right foot. Wiretap is not easily controllable. even with a huge map wiretap is really best suited for extending fueling from 2500 rpm and above. it should not make up the base of your tune. wiretap is ~%25 of fueling possible. the timing piston moves a ton on stock tuning. the quad doesn't add additional movement.

I'd be looking at the 57 sxe DAP has, or a 351 cw if you want to piece something together on the cheap

what kind of waste gate are you running with 62? Is it opening soon enough to let the 475 do the hard work?

lvl 1 power.

you felt it get weak after 2800 because of lack of timing. You should have a good hard pull to 3500 rpm. The VP is starting to fall off beyond ~3250 rpm but it is still able to do 600 hp at 3500 rpm. plenty of dyno logs show that. I won't be worried about limiting RPM to 2800 as you are leaving a lot of fueling rpms on the table. A truck tuned well revving out to 3500 will be faster than a truck shifting at 2800 rpm. You lack of canbus is in the data log is why it feels like a 450 hp truck not a 600 hp truck. The lack of boost reading at the sensor at ~1800-2200 rpm is what is causing that lack of canbus fuel. I would expect your setup to be making 10+ psi before 1800 rpm on a WOT 3rd gear pull and 50+ psi above 2400 rpm. I dont see that in your logs. The data logs from the edge comp show ~28+ * of timing from 2500 rpm and above. I seen max timing commands multiple times, at 31*. you were asking for ~5-6 less timing than that in your orginal tune. That's a big difference. A VP should be maxing timing at 30* be 3k rpms unless it doesn't run well.

because I coded a max of %50 fueling for tha tuning variable. asking for %100 wiretap of 2000US at idle is dumb and people would be blowing up their trucks left and right. setting to %50 means you will get no less than %50 wiretap at WOT and climb towards %100 based on other sensor input. I wouldn't even be messing with wiretap until you figure out your base tune. The tune I suggested only has a heavy fueling table because you said you wanted that. I wouldn't run that tune as it is too fuel aggressive for my taste and my testing showed 0 increase in performance when running a fuel heavy tune vs a tune that ran clean.

Remember the ECM is fueling based on Boost, RPM, and Throttle input. low boost, high rpm low throttle = low fuel. The quadzilla is taking the ecm's fueling request based on it's own maps and multipling the ecm command by whatever you have setup at X psi. So yes, you will get harder fueling if you push the pedal down more. All of your canbus tuning should be done at WOT situtations so you have a nice smooth fueling curve that is WOT when you put your foot into it. Not doing this will try and shovel all fueling into a small % of tps input.

when you were starting out at %92 were you using WOT to go fast? Nearly positive your bucking is related to a lack of timing after ~2k rpm

If you want to use more throttle then drop your canbus fueling % to be less aggressive. Start at %90 and work up by %2 until you hit 10 psi then ramp up by %5 You will still get the same total fueling as you will be using heavier throttle input. You have move than enough injector to get your turbos going without wiretap at all and using only stock mapping. I believe you have a map sensor that is reading lazy. Looking at your datalog I have no confince that your map sensor is reporting valid information.

something is causing your boost reading to be WAY low. I have been in a couple 62/75 twin setups and they don't build boost as slow as your truck and they dont taper off at 25 psi like yours does. You lack of canbus fueling is causing a significant lack of power. SHoveling all wiretap between %30 tps and 65 tps is going to be EXTREMELY SURGEY. You are also not setting any timing settings please try this tune. and use heavy throttle input. Your tune other tune is shoveling wiretap at above %30 input this is why it is not smooth and why you can't go WOT.

you need WAY more timing than you are running for the fuel you have. I would be running 15/18/24/28/30 please post your entire tune. I am going to go back again and tell you that %50 vs %100 throttle is %100 in your mind. Shoveling all fueling between 0-50% throttle is just going to make the truck more jumping. Key difference between the edge and the Quad is the quad is multiplying the stock fueling command rather than adding to it. This means that your Throttle input is CRITICAL if you want fueling to be higher because the ecm using throttle input as a key value to tell how much fuel to command. You can kind of tune around this and tune the quad to fuel at %50 throttle, but with the ECM knowing it is at WOT you aren't doing yourself a service. If you want WOT go WOT, that's what the pedal is for. Something is up with your boost reading as well. It is WAY to low for the fuel / air you have. I would expect to see that 62 come online WAY before 1800 rpm. I would check the jumping in the box and ensure it is not connecting both pins as it seems like maybe your map sensor is setup for a late model truck rather than an early model. This would explain why the ecm is seeing such low boost.

@rogerash0 why not go WOT? if you are asking for %100 wiretap you are techinically at WOT regardless of where your foot is on the pedal. post your full tune. also post a data log of your run so we can look. I think what you are effectively doing is trying to force all your fueling between 0 and %50 throttle input then %50-100 is all the same.

I did not note any difference in EGTS with the VE when manually setting the vanes from 9cm to 18cm while cruising. For whatever that is worth there are varous tunes inthe downoload area. any of the small injector tunes.

Yep it is possible, but pointless.

Somethig is reaching end of life if you are seeing that steady decline.

maybe it's called light throttle load or something like that.

yep, you can run a lot of timing without issues.

set your cruise load limit %5 above what your typical highway cruise load is.
