I have eliminated the quadzilla I've also tried multiple tunes but they make I worse, I've went through that whole diagnostic page and cant seem to find anything out of spec but when I go to freeze frame it shows nothing. I messed with the map sensor harness and replaced it and now it will rev higher while driving but still pops and won't go past 2300 while free reving?

Hello there's everyone, hope y'all are doing well I've been fighting an ongoing issue that renders my truck useless, it will not rev past 2300 rpm no matter what you do, once you get past 2000 it pops and misses terribly here's the codes are 1698 ive had forever with zero issues and the p0230 is from my air dog. my grid heater is deleted so I believe that's the other two but the p0251 makes me wonder. It's not the VP as I thought because I got it warrantied with no better results any help would Be great thank you 61619919762__5C17D84F-A4A4-46C2-AA6C-40B6342BFF4C.MOV

So after some digging, I finally found the issue, the vp44 finally threw a code. P0251 checked all the wires, all came out good. Sent it back for warranty Monday to blue chip and I should hear back soon

So i found the issue to be as stated before the headlights are ground controlled fixed, still no turn signals but today I was driving around and got a no bus on the dash and the truck will not rev past 2000 rpm. I have no clue where to even start. I’ve cleaned all the grounds and checked all connectors. IMG_2032.MOV

That sounds accurate, I pulled the light switch out of the dash and ran power to the wire that goes to the lights, forgot the color of course but do you know which wire would be the current “ground feed” that I could cut and change it to a “positive feed”

So it seems like a possible multifunction switch and possible wiring issue for the positive side of the lights? Today while working on it the turn signals have now stopped as well so now only brake lights

I swapped my 1998.5 drivetrain and engine wiring harness into a 2001 1500, all fuses and relays are good, I only have reverse, turns and hazard lights the rest of the lights do not work including dash, tail, running lights and headlights. The high beam indicator on the dash always stays on no matter what. I have ground to all lights just no power any ideas?

Hey there guys, so I got an update, I receive my turbo Monday but I received an s400 Schwitzer (Borg Warner) with a t6 turbine from a friend, got it for free it was brand new in the box! Just has some surface rust from sitting a while does anyone know any specs on this turbo or where I can find any? he said he bought it for his 12.7 Detroit but never put it on. Could I use this for compounds with my SXE362? the top part number is 167735 And another Update... after some digging I believe I found some specs!! Looks like it’s a 69/83/1.58 AR

That looks like it turned out really well! I just ordered the 62/68/.7 and a 5” hx40 downpipe so hopefully by this weekend it’ll be here and I’ll let y’all know how it goes!

I think I’m in the same boat, I have a super tight tc so I think the .7 will be way faster off the line. The 7x.12 will be enough fuel right?

What’s a 62 single capable of? Would you go the .7 or .8 housing?

Howdy there everyone, hope everyone is well and healthy! So during this “pandemic” slow days at work has given me more free time to mess with the 24v so I have some 7x.12 nozzles that I’ve had laying around but I know they’re way too much for my he351 because as of right now I still get tons of turbo shutter, looking at new turbo options, on Power Driven Diesel my preferred place to get parts, they have upgraded he351’s 62,64,67mm anyone have any luck with these? Or I’m looking at an sxe 362 or 364.5 if I was to go this route would I go a .70 or .80 t3 housing? I’m looking to be around 550-600hp on a single yes I know compounds the way to go on these 24v’s but man dropping 3k to do them is hard. I tow heavy 15k+ sometimes but not that often I don’t want too much lag as I like to DD this truck while also some back road street drags on the weekends. Y’alls input would be great I’ve read a lot but still can’t come to a conclusion!

So update, I tried to reflash my unit and when I plug it into the computer it doesn't make any sounds or anything. the mini-b cable I bought says charge/sync on it so it should work, When I tried to install the driver 'devcon failed'

I’ll try to reflash tonight, see what happens and then send it in it’s just weird how this happend out of nowhere. Never had any issues in 6 years

I don’t believe it would be under warranty though, should I try a reflash?

I’ve had a quadzilla on my truck since 2014, great results. But last night I went into my truck to start it, nothing no lights or anything both batteries dead, unplugged the adr then let the batteries charge overnight. Started truck, shut it off plugged my adr back in, crank no start unplugged the fuse tap and plugged it back in started but runs like crap. Unplug the ADR and runs perfectly fine. I have the iQuad and it will not come up on my WiFi connections.... when I shut off the key And pull it out my dash dummy lights stay on (Abs, CEL, low fuel, etc) I think this is why my batteries died but when I unplug the adr they all go off. Is my box fried? I pulled it out of the cover and there’s no signs of any burning or dark spots on the board. Any help would be greatly appreciated!

Oh man, they drive me crazy I’d rather the trans go out on me, because then at least I could just build it and move on electrical mysteries are like chasing your own tail

Sounds close but my tachometer always works and the rest never work at all, it’s odd because the water temp gauge shows nothing but my adrenaline will pick up water temp but nothing about the speedo

Thank you guys for the input so far, sometimes these issues make me miss my first gen! I’ve checked the connectors behind the dash they seem okay but never really clip in they just sit in the plug, sadly the overhead console does not work (previous owner) pulled that harness out and the cab light harness I just found a used overhead console for 20$ so it finally has an overhead console just has to be wired

First post here, a pleasure to be here! I’ve been fighting with my gauges for a while now and it’s driving me insane. I have read many pages on here and other forums but have not found an exact answer or fix. My tachometer works, all other gauges inop my transmission shifts great. When I connect my scanner (Snapon Zeus) I can pull codes out of the ecm and get codes P1698 (No transmission bus messages) and P0230 (transfer pump circuit out of range) I believe that is due to the airdog. Many of my dummy lights are on. The wiring in this truck is a nightmare due to the previous owner. Any help would be greatly appreciated!
