C7 Corvette Burble Tune ***POPS, BANGS, & CRACKS!!!*** Deep Dive

I figured out why my burble tune's drivability was less than ideal. In this deep dive, I'll show you how to create a really drivable burble tune, and I'll show you how to make it more or less aggressive to suit your preference.
I’m using an interface and software from HP Tuners.

Dude.... great video. I been wanted this explanation for a long time. You should work at NASA

[@a_as_in_tony9855]

Thank you for the video bro , I’ve been looking for a video all over KZbin ! I will be tuning my C7Z like this soon!

No problem! Glad I could help!

[@snvffxxx]

Thank you Rob. really appreciate it.

I wanna see you do a POV drive of this car so we can hear more of that poppin' and crackin'.

[@RobsHouse]

Next upload will be an installation of the DSC Sport Mag Ride Controller and there will be a ride along in that video with plenty of pops and bangs :) also will be doing some dragon rips this season and I’ll make sure to get cabin audio in there because it sounds insane on the dragon!

[@RobsHouse]

I just posted a reel of me driving it on instagram the other day as well if you'd like to hear the pops. Instagram is @robshouseofficial

sounds great!

[@robjordan204]

Dam, bruh... How do I do this with just a hammer and screwdriver and some "duck" tape....Lol

[@RobsHouse]

😂😂 I wish there was another way!

[@tjwong007]

I tried your settings in a 2017 ZL1 I can get it to not go into DFCO but it won't pull timing to the neg numbers. If it goes into DFCO I can see it go neg but there no pops because theres no fuel to pop!

[@RobsHouse]

The pops happen during the transition to DFCO. It probably isn’t pulling enough timing prior to DFCO entry

[@Seb726Laviolette]

Mine is a stock no tune 2019 with xpipe and it does pop pretty good.. Maybe they changed the stock tune a little bit for the 2019..

[@RobsHouse]

They did. I have a burble and non-burble tune loaded onto my NGauge. The non-burble is the factory 2019 minimum tables and it does pop and gurgle slightly. Obviously nothing compared to the burble tune, but it has some character at least haha

[@Seb726Laviolette]

Kk cool thats what i thought and no does not pop like a real tune but once in a while if you punch it and release the pedal quickly you can get some pretty good ones!

[@shaoun5876]

Mine is a 2019 Zo6 pops with each and every down shift full stock zero tune

Works with any exhaust. It’ll just sound slightly different.

[@carlautogarage2561]

HI Rob, I have a stingray lt1 and would love to have your pops and bangs, cracks on it. Have the file read out. How much will it cost if I send to you for same job you did on your car. Thank you

Shoot me an email at [e-mail]

[@ChadBIsRacing]

Hey man, found your thread on HP tuners.. This sounds great! What changes have you made since?

[@RobsHouse]

Well the car has a cam in it now. So I redid the entire tune. But the strategy is the same for the pops.

[@ChadBIsRacing]

@@RobsHouse Cool, I'm reviewing the tune now..

[@cal.or7]

Hi Rob , stock Ecu? Maybe you’d be interested in a remote tune? 1971 240z with c7z06 lt4, would love for some burble and flames

[@RobsHouse]

Yup it's a stock ECU tuned with HP Tuners. Mine doesn't shoot flames but it has some serious burbles.

[@angelojohns3189]

Ok I want my c7 to do this I'm In Orlando likw where I go to do this I have no clue about computers ans what your doing in the vid but I wa.t that sound help pls lol

[@RobsHouse]

Unfortunately, I can't really help with that. I could remote tune it for you if you had an HP Tuners device and knew how to flash tunes using it, but that's about it. I would say just take it to a shop that knows how to tune Gen 5 GM vehicles, but unfortunately those are few and far between in my experience.

[@mustafajan5910]

This is really cool I was wondering if this doesn't cause any problems?

[@electric7487]

You will have to delete your cats if you want pops and bangs. That means stay out of California and register your car in a region that doesn't have emissions testing.

[@RobsHouse]

@@electric7487 You can still do it with cats. The pops won't be as loud. It will shorten their life though for sure.

[@lukedewitt9428]

Hey so i cant edit my virtual torque settings. Do you know of a fix for that?

[@RobsHouse]

Make sure your VCM editor is in "advanced" mode.

[@jonasdasilva1611]

Hey man love the video looking to do it on my corvette just wondering if it ruins the engine or anything thanks

[@RobsHouse]

Been running it on mine for 20,000 miles so far. No issues on my end.

[@alexaughenbaugh885]

Hey man, love the video. Is there a way to tune the car where the burbles are only in sport or track mode? Or is there a cheap gauge/controller where I can load multiple tunes? Thanks.

[@RobsHouse]

Yeah. You'd basically mess with the 0% accelerator position driver demand tables. There's the normal table and then the sport/track table. You'd just set the sport/track one to be more aggressive (lower values in that row) and have the normal mode use higher values so that it doesn't ramp out as much timing. It'll likely still pop a little, but not the super aggressive pops. As for a controller, you'd just have to get your own HP Tuners interface. There used to be an HP Tuners N-Gauge where you could have multiple tunes, but N-Gauge got EPA'ed out of business :/. I always carry my laptop bag with me anyway in case I need to scan codes or something.

[@ericellison7586]

If you want flames lose the cats and mufflers, if you have them

[@chaznad5411]

Hey!! Awesome video. Was curious how this could be done. I guess my question is … I have an 800rwhp c7. The current exhaust is kooks headers/xpipe , npp Will this cause issues to performance I don’t want to risk issues

[@RobsHouse]

I show how to do it in the video. It will not cause performance issues if done correctly. It only affects how much spark is pulled under deceleration. Doesn’t affect anything else

[@adammason1587]

@@RobsHouse I am assuming it only affects gas mileage because of unspent fuel, actually does it cause any issues with the cat?

[@RobsHouse]

@@adammason1587 It will affect gas mileage only if you disable DFCO. If you leave it enabled like I did, your fuel economy will be unaffected. However, it will definitely shorten the life of your cats. By doing this, you're allowing combustion to happen with the exhaust valve open essentially. So, the exhaust will get hotter than it would otherwise get. Extra heating of your cats will shorten their lives.

[@Bedwetter2012]

Is their a way to get pops on upshift for a manual stingray?

[@RobsHouse]

Yes. Just disable clutch fuel cutoff (CFCO) under the DFCO/fuel cut settings. There’s the decel fuel cut (DFCO) and the clutch cutoff (CFCO). If you disable CFCO, it’ll keep fueling while you shift and it’ll pop.

[@josea7137]

Hi, I have a doubt. With these virtual torque settings. Do you get the farts yet? Or does it have to be complemented with adjustments in the minimum spark table? I already had it done in the minimum spark table. I have also applied the virtual torque adjustments. It gives me the feeling that now it explodes stronger and with more fire... And another doubt. This was 3 years ago... is there a better way to do it now?

[@RobsHouse]

You need both. The minimum spark adjustments are to allow it to pull more timing, but with the default torque tables, it will stop pulling around 0 degrees. If you want to go into the negatives to get big pops like I did, you need the torque table modifications. There is no other method. The Gen V GM platform is torque-based. There is no getting around it.

[@josea7137]

@@RobsHouse Yeah. I have done. Now I get the strongest explosion.. but it still doesn't decelerate well at all... in 2nd gear it still pushes me when I release the accelerator... I have adjusted the spark to -20... maybe it is too much. DFCO is in stock. and the 2nd speed for example... when I decelerate it seems that DFCO does not work in the entire RPM regime... it is making bubbles all the time and the complete fuel cut-off does not come

[@RobsHouse]

Something must be wrong with your torque table settings. Mine reaches DFCO just fine. If you messed with the decelerating tap rates in the torque management, that can cause jerky behavior and/or not reaching DFCO. Those shouldn't be modified.

[@josea7137]

I think I applied it well. if you send him the file. Can you verify it for me? I could send it to you if you tell me your email.

[@jaskaransangha7037]

Hey for some reason mine doesn't go under -5.5 in spark

[@RobsHouse]

Probably have to be more aggressive with the torque tables

[@yousefalkhudair4420]

Are they bad for the car ?

[@RobsHouse]

it will decrease the life of your catalytic converters if you have them. Aside from that, no.

[@danteros9460]

Can this work for a ls3

[@RobsHouse]

Yes, although the torque management system is probably a bit different. I haven't messed with one. I believe they actually have a DFCO entry and exit spark, so you could probably just play with those values and achieve the same effect. Just lower the entry spark and your minimum spark values and it should do something similar.

[@tylerfrost040192]

What if you have an aftermarket can with a lockout and your intake can angle is always zero degrees? Would this method then affect drivability?

[@RobsHouse]

It will not because you're limiting to only messing with the deceleration cells. I actually have a cam in mine now, and it drives fine still.

[@tylerfrost040192]

@@RobsHouse you don't think those affected cells in virtual torque tables will relate to idle/take off transitions? Not arguing at all. Just curious what you think. I've already created a new file to flash when I pull my truck out of storage in the spring.

[@tylerfrost040192]

*Following this guide

[@RobsHouse]

I had all these same concerns when I installed the cam, but from my experience, it doesn’t affect take off because you’ll be at a higher airmass as soon as you touch the gas. Throttle will open and your cylinder airmass will increase. However, it can definitely affect idle which is why I only messed with 1800 rpm and up. To that end, taking off from a stop shouldn’t be affected even if the airmass was still low because I didn’t mess with the torque tables that low in the RPM range. I started at the 1800 rpm column so that it wouldn’t screw with idling or really low rpm stuff (stop and go bumper to bumper traffic for example)

[@tylerfrost040192]

@@RobsHouse makes sense, I'll alter it to affect the next column past 1200 (1600 on my file?).

[@corywimberly8043]

can this be done to a c5 using hp tuners?

[@RobsHouse]

Most likely, but I’m sure the procedure is different since it’s a different ECU. I have never played around tuning a C5
