Im looking at getting the flashpaq by super chips and running the 87 tune and disabling the DFM BS.  Has anyone done this?  I’ll be doing this in a 2020 GMC Sierra 5.3 10 speed.

 

My main concerns are Illinois emissions and towing.  
 

I’m wondering if I will fail emissions or get a “not ready” status running this tune with DFM disabled?  I’m also wondering if it’s ok to tow with that 87 octane tune.  The one video I watched on it said it’s not for towing for some reason.  
 

Just wondering if anyone else has gone this route and can answer these questions and maybe give me some honest feedback about the flashpaq.  Thanks.

Matt, 

I have the Superchips Flashpaq. I ran the 87 tune for one tank, and I will tell you it is not worth it. The tunes will not affect emissions, but if you are considering using it for towing, use the "tow tune" and run the higher octane fuel. The 87 tune will likely not get you the performance you want. 

 

For context: I have a 2021 GMC Sierra AT4 with a 5.3 10 speed. Exceptions - I am running a Fabtech 4" lift, 35x12.5x20 Toyo AT3 tires, Cold Air Inductions CAI, and the Borla S-type exhaust. 

 

Flashpaq bonuses: the button memory is great; it disables all the silly things you don't want a V8 to have. The calibration for tire size is pretty much spot-on. The pedal sensitivity adjustment is enjoyable, but it can decrease fuel economy due to the fun of it all. My "real world" numbers on 93-octane and the performance tune: average of 425 miles to empty on fill up; 17-18.5 mpg by hand and on the computer (400-mile distance calculation), and incredibly fun to drive. 

 

Respectfully,

Doug

Hi, so is there a HP/ TQ  gain with this in the performance tune or is it just the throttle sensitivity?

Is the the one that has the "locksmith" to unlock the ECM and the TCM?

The performance tune has a modest HP/TQ gain in addition to the throttle sensitivity. The "performance" tune is more HP than TQ, while the "haul" tune is TQ-focused. The power increase is not as drastic as the numbers you are going to see with the 6.2 (which are the numbers they advertise), but I have no issues with get-up-and-go running a lift and 35s while doing truck things. For the 5.3, it definitely increased the joy of driving and seat-of-the-pants performance.  

 

It is important to note the "performance" tune is not for hauling, but with the ease of switching tunes, it is not a terrible headache to switch when I need to haul something (which is not very often and planned well in advance).  

 

Yeah, you have to send the ECM to the company (Holley is the parent company, I believe) to have it unlocked to work with the handheld flash tuner. It was about a 72-hour turnaround. 

 

My only concern now is whether or not I am able to add a supercharger since another company unlocked the ECM. I am going to send inquiry emails to tech support at Magnuson and Whipple to see if I can use my current ECM or if I need to get a new one for the supercharger tuning.

Update: You no longer have to send the ECM to the company for unlocking. They sell the FlashPaq with Locksmith device, which allows you to unlock everything in your garage using the hand tuner and update software via your personal computer. The new system (2849-F) allows you to unlock the TCM previously unavailable on the older FlashPaq tuner for the 19-22 Sierras. This is great because, depending on what tune you used, some of the shift points would be a little off (surge/holding high RPMs when not accelerating). 

 

I have reached out to Superchips to see if there will be a kit/software update for those of us with the older FlashPaq (2847-S) so we can benefit from unlocking the TCM and correcting some of the shift issues.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      I went through again with a test light and everything checked out.    I suppose it could be the MAF itself but I've tried 3 different sensors, 2 of which were in running vehicles previously (the one in this truck, and the one in the donor truck), as well as a new one I picked up from NAPA. I would just be surprised if all 3 were bad.   EDIT/UPDATE: I swapped in the MAP sensor that was originally with the 2010 PCM, that made the code for map sensor voltage high Go away, and the map sensor seems to read normal with key on engine off (14psi or so), but it still doesn't run and does the same thing as before.

      No Software Updates - Old Build

      By Atlas · Posted

      In addition to a cell or wifi connection, the infotainment needs to be enabled to download software updates. That's a toggle within the system settings.   But...if the truck was prevented from receiving updates in a past life, missing a bunch of updates may mean it won't go back and download all of those because they're not available or the system is too far out of date.   If a formal recall depends on a software update, the recall for that truck remains in an open status until it's applied. The dealer would need to apply the software update in that instance.   Most updates downloaded and applied via the infotainment aren't recalls/safety recalls, they're enhancements and usability fixes which aren't critical.

      Brake Pad Warning Message

      By Vu1can · Posted

      Recently I've been getting a message, "New Brake Pads Detected. Reset Brake Pad Life?", But I haven't had the pads replaced and the truck only has 28,000 miles. The Brake Pad Life shows Front 64% and Rear 79%. I select NO to resetting the brake pad life and the message goes away but comes back at the nest restart.   I stopped by the dealer and was told that it sounds like a software glitch that would require reprogramming. Even though I have the extended warranty, they tell me that reprogramming is not covered unless a module was actually bad and needed to be replaced. Simply reprogramming is not covered. So, they want $200.00 just to diagnose the problem. If it turns out no bad module, another charge on top of that to do the reprogramming. If the cause was an actual bad module, everything would be covered under the warranty.   Just wondering if anyone else has had this problem. Should this issue be covered under the warranty?   Thanks

      NHT is diesel only, correct.     The GVWRs for NHT on 3/4 ton bring them to the same numbers as many of the 2WD 1 tons.  A crew 4x4 standard 3/4 with NHT is 11,750lbs, a 1 ton same cab/box/4x4 is 12,100lbs.     Hubs and hub bearings are the same for 11.5" and 12" axles.  Housing, diff carrier and ring/pinion are larger for the 12".   All gas use the 11.5" axle, 3/4, 1 ton and 1 ton DRW.
