Make sure you do not void your factory warranty.

 

The guy at the dyno shop verified with GM there are no flash counters in 2014 models. They will start in 2015. Sent from my iPhone using Tapatalk

 

Where is he getting this from? How was it verified? My service department helped me get around tuning on my old truck and he flat out told me don't do it on the new one. They are mod friendly and they have always been willing to help out the customers with those things.

 

All 2014 trucks record and show any changes done in the computer. I was asking for my tire/speedometer adjustment and he said that's even recorded. If you want to take the chance more power to you but with 4 recalls already on my truck I'll wait a couple years.

I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Karnut. Seriously I cant really just put a number on it because of the amount of responce you get in your throttle!!! If you put it on a dyno the peak numbers will or could have up to 25-30 gains but

Yeah you all make good valid points.. I just would love to feel the difference with it tuned up and what not. There's so many adjustments they can tweak it's crazy. And under normal dd it would be ideal I think.. But at the end of the day with this being a first year model and potentially having issues down the road I don't think it would be to smart to hack into it. Ugh lol. Guess the positive side is I still have my diesel. I may hold off on the tune and maybe down the road after some more research and development it'll make more sense. The last thing I need is to tune it and have an issue that'll make me come out of pocket for. Thanks for the responses so far it's helping me out I have no doubt the truck could handle the tune.. My main fear is future recalls or anything of the sort and having it tuned will void me qualifying for the fix. I don't think the possible 15-20 hp will be worth thousands of potential dollars out of pocket to fix something connected to the tune. Sent from my iPhone using Tapatalk

 

You might ask MotoMedic...I'm pretty sure he had his 5.3 tuned by Black Bear and I believe they told him that GM would be none the wiser if he takes it in for service.

These guys say that dealerships cant see their tune

There are a couple of guys that post here on the board. I messaged them asking them to explain how they get around this and got no response from either one.

The problem with this is that no one is 110% sure. Yes, you read all kinds of things online stating whether or not a "foot print" is left from the tune. Maybe in the years past.. they know for sure. But the new 2014 model.. still too new for know for sure.

Quoted from an email correspondence with Justin from Blackbear.

 

"There is history tracking in them just like there is in a number of newer gas platforms as well as Diesel trucks. I don't know what the law is like in Canada, but in the US, the manufacturer cannot void a warranty just because they want to. They can try, but unless they can prove that the modifications made was the cause of a failure, they don't have any footing to stand on. This is the Magnusson Moss act here.

 

I would also like to note that in gas engines, they've had tracking since 2011 with the 2500 series trucks. We have yet to have any customer have an issue with warranty work. Tuning alone just doesn't stress any component out enough to cause an issue."

 

For any Canadians reading this, we do not have this act in Canada.

Tuning is the one area where I think the OEMs have consumers by the balls with respect to warranty. I think any laws favor OEMs with respect to the tunes. Under normal circumstances, yes, they have to prove that the mod led to the failure. That's easy and more clear with suspension lifts, larger tires, power-hungry accessories, etc., but tunes could be added and removed without them knowing. Hence why they added the tracking. And why would they add the tracking if they don't think they could use it against you? They wouldn't. It would be a waste of money and effort.

 

Don't be fooled, OEMs know that tuners can modify all sorts of parameters that can potentially and very easily damage your engine. And they know that tunes can be removed before service. That's why they implemented the new tracking protocols. I have no doubt that if you get caught with any tune and a powertrain failure that they will blame it on the tune. Knowing that you modified the engine and/or tranny in a way that it was not designed to operate is all the "proof" that they need to void your powertrain warranty. That's the sole reason for adding the tune tracking - warranty protection.

 

That being said, I would still consider a tune in the future. The main concern right now is with long-term reliability of these new engines and all the TSB/recals that could possibly occur. Give the engines a year or two to see how they last and to let a majority of the problems be worked out. Then if no significant problems, tune away. Or if you don't plan on owning your vehicle for more than a couple of years, tune away. Just do it understanding that there's a very high probablility that your powertrain warranty will be voided in the event of a failure. If that doesn't bother you, then go for it.

you can run E85 and get a nice little bump in power.

And 20% reduction in fuel economy. For example, a 2007 Impala with the 3.5 liter V6 gets about 17 MPG, a 2004 Ford Explorer 4X4 12 MPG average on this stuff. Both vehicles do at least 20% better with E10.

Power>fuel economy. At least for me.

There is not a "flash counter" but there is flash history tracking. This is only updated if the ECM thinks that the tune has changed. You can flash the same tune file in 100 times and it will not register it.

Black Bear uses your factory tune file (which you DL with AutoCal and email to them), tweak it, and send back to you. It's the same file just different settings.

While as said GM just cant void the warranty and by law they have to prove the tune caused the problem. In all reality though who on here has the $$$ to take it to court and win against GM or any other manufacture. That is where the manufactures know they have the consumer as they know none of us can afford to challenge them all the way to court and even if you did they would bring an engineer who would testify on their behalf that your tune pushed the power past the tolerance that the parts were designed for and directly caused the issue.

They know with a Duramax almost instantly, all they have to do is bring up the soot mass log and EGT log. If they really know what they're looking for it's not very hard to pick it out...but do they look on a gasser? I don't know...

 

I do know it's very easy with a diesel, because usually tuned HD's come in with burnt trannies and turbos lol. Guys try to get away with it but the black box catches the scheme!!

 

but I don't know with a gas truck if they would look or not....depends on the dealer I bet

      2014 silverado wt radio and hmi upgraded to i06
       
      This truck never had a back up camera. Upgraded from i04 to i06 via hmi. installed proper back up camera in tailgate, plugged in to RC port. BUT
       
      The error from the ecu indicate that the line is open. So, my thought is that the wiring is not there. I was told if the grey and yellow wire are there its there, but even if it is from the back to front, it might not be across the front to the unit.  I was temped to use a harness that would plug into that plug and add a simple rca add.
       
      So I have a black screen with  directional lines that work. Then it goes black and days service required.
       
      I took it to the dealer, they want 1200 to do it all. uh, no. I need a simple solution. help guys. please.

      I have 2014 Silverado and went to the gas station one morning and out of nowhere started smelling gas inside of the truck. Long story short, went to look underneath truck and had a 3x3 ft size puddle of fuel underneath truck on ground. Looked to see where it was coming from and looks like it’s coming from back side of motor. Can anyone help or recommend any action to take from this?

      Hi
      I'm new in this group, I hope you guys could help me out.
      I'm driving a GMC SIERRA 2014 ALL TERRAIN MODEL and I been trying replace my blower motor resistor, but the problem is that... I don't know where is located, according Google, amazon and o'reilly I bought the correct one. Every body is saying that is normally next to the blower in the passenger side, but I couldn't find it. I'm leaving photos to show you guys how it looks right where the blower is..
       
      Thanks

      So ive been seeing the conversion on 08-13 Sierras , and very popular on Silverados even the 14-16 conversions. On feb 1 some jack ass cut me off and hit my front bumper and fender , lucky for him i was already looking into doing a 2018 denali headlight conversion with the gen5 wiring harness and 2015 HD front bumper with 2500 all terrain grille To keep the theme going. As I researched could not find anything on the 2014-2018 sierras being converted to HD , all the guys i saw on IG with them had shops or buddys do them. Some guys welded either the 1500 or 2500 brackets lower ,enlogated the holes lower, redrilled , some had no gap -some liked oem gap between the grille/fenders. I did find two guys I kept intouch with they were a lot of help. One sent me pictures on how to re-drill the stock bumper brackets lower and cut some parts off it to clear the bumper , the other told me 1/2 above the existing holes . I took it upon myself to source a complete front bumper from ebay with everything $750 with shipping all i have to do is paint it , found a all terrain grille on ebay for $300 , had to buy the 2500 bumper guides and 2500 bumper fillers no luck on hood yet.while the parts arrived i bought the 2018 denali lights from fankie on here and the harness from gen5 easy bolt on by the way. When all the parts arrived i grabbed my grinder and drill .
       
      To start i took the 15torque head screws and 7mm from the sides of the wheel wells , took the 12 plastic clips from the upper cover , removed the 4 top 10mm bolts ,pulled off the bumper filler pieces between the grille and bumper , exposing the 10mm 4 bottom grille bolts , then removed the grille. Gaining access to the 4 18mm bolts that hold the bumper on the brackets, i loosened but did not remove till i went under the front bumper and removed the 2 outter 15mm bolts that hold the bottom of the bumper , i loosened the inner 15mm bolts but did not remove , once that was done i removed all 18mm bolts  holding the bumper and took it off . Once off the stock 1500 bumper brackets have 3 15mm bolts in a triangle pattern, i removed all 6 and removed the tow hooks , the tow hooks will be eliminated from this . Once i had the brackets off i measured 1/2 inch above each hole . Now this is important if you want oem gap like myself i drilled a hole slightly bigger than the bolt going threw at the center of that 1/2 mark . If you dont want gap id suggest drilling under the 1/2 mark and possibly enlongating that hole down wards for adjustment. By drilling the hole a 1/2 inch higher it drops the bracket to clear the 2500 grille . In addition to redrilling the bracket you have to cut an L shape on top right next to the top bolt that the bracket has , i actually cut the bottom of the bracket and eliminated the bottom slot for the second 18mm hole because i was having issues lining up , ended up not being the problem , i found that out of the 6 15mm bracket bolts you only use 4 the top and inside 15mm the outter 15mm that completes the triangle actually hits the hd front bumper and it sags in the back ,so removing levels the bumper flush , i tried grinding the head down and still no luck removing was the fix. With the bumper off , you want to remove the 1500 bumper guides 3(7mm) bolts rachet wrench works best and socket aswell , install the 2500 bumper guides with same bolts same place these support and clip on to the new 2500 bumper filler pieces under headlights which youll have to buy . They clip and slide right on , the two bottom outter 10mm bolts that held the old grille will hold these in place and the other two 10mm in the middle from the old grille will be eliminated. See pictures.To finish securing the bumper filler and guides you have to screw the  7mm and 15 torque screws by fender trim , you will either have to buy the 2500 or 18 fender trim pieces or just trim yours roughly enough to bolt on the remark to trim perfectly and level like i did cant even tell .So Once the guides and fillers are installed grab the redrilled bumper bracket to your liking in gap, make sure its clearanced with the L shape you can rebolt bolt to frame leaving the outter 15mm off at that point you can lay the new bumper on the brackets rebolt the top 18mm bolts the bottoms wont line up -i eliminated by grinding off ,see pic -you can reconnect the lower 15mm outter brace and tighten , youll find out that it bolts right up and if you drilled at 1/2 center like me you keep that stock oem gap maybe a bit tighter gap actually but it looks good , you can then install the grille by pushing the clips in and only bolting on the the top 4 10mm bolts once done youll find that the gap is nearly perfect if you drilled at center of the 1/2 mark , some drill under the 1/2 mark to get less gap and some enlongate the hole lower towards the original hole  to adjust and have no gap , but i see that as rubbing issues with paint.
       
      sorry for rambling on on the install , i will try to post all my pictures size will be limited and ill go back to proof read fix anything that i missed. Let me know waht you guys think or if you need help

      Looking for suggestions on front coilovers for 2014 SIlverado 4x4, I currently have a 3" motofab level kit installed including aftermarket Motofab UCA (Which I am not happy with and will be swapping out)  Nevertheless I would like to maintain the 3" lift but go away from the spacer to a coilover kit without breaking the bank.  I have been looking at the following and interested in feedback outside of going to a full blown 4" lift which I'm trying to stay away from but not opposed too either.  Also to mention this is my daily driver so more on road than off road use.
       
      Bilstein 6112- won't get me to 3" only 2.75 at highest setting (maybe)
      Eibach Pro-truck Coilovers 1.75-4" $850 which I'm leaning towards due to price but not familiar with the coilovers I know Eiback makes a good spring which is used on several other brands including FOX
      Zone Coilovers 0-3" around $2K to purchase  (Ouch)
      Icon 1-3" Coilovers about $1720
       
      these are just a few I have researched but open to thoughts and suggestions and looking forward to the feedback, I'd like to stay under a thousand if possible.
