Anyone running an HP Tuner on their N/A, Catback 5.3 K2XX? If so where did you get it from?

Yeah, I've been using HP Tuners since 2012.

 

I bought it straight from HP Tuners themselves, why hassle with summit racing or any other re-seller when buying from the actually company is that easy. You'll need the tuning device plus however many credits your vehicle takes to license.

 

Just know that HP Tuners does not come with tunes or anything, the user is the person making all the changes so you will need to understand how things work in the GM world of calibration.

Okay, I’m coming from the Cummins world, where you could purchase pre-tuned EFI Live downloaders. That’s why I asked that way.

How much of a bear is it to tune? I am computer savvy, but I don’t wanna screw things up

I'll be honest here, if you've never done anything like this before it will not be easy. The 2014+ trucks run basically the most advanced calibrations that are out there for GM vehicles aside from the T1 trucks that just came out.

 

There are courses and books/video's you can buy to better prep yourself. Greg Banish at Calibrated Success offers books and video's. There is also The Tuning School and many youtube video's to shine some light on what you will be dealing with.

 

I learned on the computers that came out in the late 90's through the early 2000's when I first started tuning in 2012, so everything I learned on those computers carried over into the newer 2007+ computers while also being introduced to new things in those computers. Then as time went on they progressed and once 2014 came, things got more complicated but most of the same basics still applied.

 

 

There are other options out there if you don't want to do it yourself. Like a dyno tune from a shops or finding a local person that does tunes. I've never been a fan of handheld tuners so I don't all of those options.

Kinda what I thought. That’s more or less what I was looking for. If I purchased the tuner and the licenses, if anyone was selling tunes or if I’d have to find someone somewhat local to me in MD.

What mods have you done to your truck so far?

Right now it’s CAI and exhaust. I will eventually go the route of forced induction, but I need something to tide me over and I was looking over my options.

Cam stated right, hp tuners is pretty invasive when it comes to control. I have been using it since 2015. I acquired most of my learning from videos and the hp tuners forum. In my opinion it is a great skill to learn if your planning on tuning or having most of your vehicles past present or future tuned. It took me a good year to learn enough to feel confident in tuning. A lot was through trial and error but helped instill the concept. I also believe it helps one understand how many of the vehicles systems work.

There are companies that will send programmed tunes for Hptuners and have you do some data logging to fine tune it.

i have the old HPtuners module,  I wish i got the pro version, as the number 1  performance tune upgrade you want to do is Improve PE tables, this is where the most bang for the buck power is hidden, close to 50hp is left on the table under PE. this is dialed down due to emmission regs by GM, 2500 truck have it turned off completly on some model years., thus why you need the live wideband O2 graphing.  I wouldn't touch the timing, until you got some seat time, I would recommend tuning your transmission first.

That’s another reason I was looking into them, because I wanted to find a product that could tune the transmission as well. I’m gathering that I should get the book and do a lot of studying first.

yes get the Greg Banish books, then watch sloppy mechanics videos and Goat rope garage you tube videos,  then you can buy the GM trans tuning books for HPtuners .  also you want to purchase the chinese  VCX Nano  device to read and clear transmission learn functions, and tb relearn, and body control computer for diagnosis..  if your really anal the factory repair manuals cant hurt. either on CD or paperback

this guy is an actual trans rebuilder so he sounds like he knows stuff.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf

      Towing In Loose Gravel

      By rdonarski · Posted

      This landing is worse than most. Patchy blacktop with washouts, soft gravel/sand at bottom that washes out with every heavy rain. I tell everyone to put it in 4WD. A lot of them think they can pull out their trailer in 2WD. They end up digging a hole and then putting it in 4WD.  The lake is a pristine lake and has a lot of money on it. There are several wake boats and lot of large tritoons. The people with the money don't want it improved because they don't want more traffic.    Boat Landing 1.jfif Boat Landing 2.jfif Boat Landing 3.jfif
