    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

BTR 2015-16 ECU + TCU Tune for Genesis Sedan 3.8 Worth it?

0 to 60 is changed a tenth is a tenth it changes transmission shift so if you have a exhaust you can hear, you will he the difference in the high rpm in the same gear. God bless.

I really think those of you that desperately want 50-100 rwhp need just pay about $6-700 and get NOS. It's the cheapest way to really get "real" rwhp in 50 hp increments. NOS has kits that will match up for the 5.0 and will also do same for the 3.8. Yes you have to refill the smaller bottles after about 20 runs, but you will blow off most current big boys with the absolute sneaker. Mustang boys have been doing it for years and most good Mustang shops are familiar with installation. It is a safe and easy system. You switch it on when you need it, otherwise no one knows. And from what I have been told by the shops, the 5.0 ECU has such a rich high rpm fuel ratio, that there is no need to go to the exotic NOS system controls or change injectors, etc. Just food for thought. Realize you will never get a really good ECU or chip for the 5.0. And the ones that are available now are just so so. See above for what you have to put up with for 35 rwhp (and this is even suspect unless stringently identically compared to the replaced original ECU before dyno testing the "up graded" ECU).
 
See that's my point, people like you are what we need ,you have the knowledge of the inner workings of a build. I know you can put a sleeper kit on a 5.0 ! Turbos underneath the car instead of the top. I wish i had your knowledge, resources and expertise. I know just enough to be dangerous, you known enough to make dreams come true, there's your excitement, there a sleeper build in your head. Please picture this twin turbos underneath, front mounted intercooler, someone has to make injectors, I'm stuck on the piping. We don't have to run 20 psi at first just 5 to 8 psi we control the the with heat turbo blankets . Just come up with the piping, we can Frankenstein a kit. To me that's why I got the tune in case someone like you came around I'd have a better chance of not blowing my motor. I would love to talk to you, if you can't figure it out I know you know someone who could. God bless you or and thank you for responding.

Just so you know you'd need a completely different tune for boost, a tune isn't a 'catch all' for every mod you do and it won't adapt to big changes like boost. You'd want to get a real tune done on a dyno, not a mail order tune like BTR does (which works for mostly stock engines but big mods need dialed in more).
 
Ok so I'm kinda new to all this performance stuff. So carguy75, I see you have a Sprint Booster V3. Can you tell a difference in exhaust volume? If so is there a way to turn the tune on and off or even adjust it for road trips and whatnot? :unsure:

The exhaust note seem to be the same with the Sprint Booster. However, the stock exhaust is really quiet anyway.

I have the V3 Sprint Booster that can be turn on and off with a press of the button.
 
Sprint booster just changes the throttle threshold. This means that you will have more throttle response with less pedal depression. There is no change to your horsepower, exhaust, 0-60 etc.

No offense, but have you even have a Sprint Booster? If not, how in the heck do you even know what results it does or not produce?

I own the device and have not really tested the unit enough to say for any certainty what it does or not as a fact.:)

I perceive that my car accelerates quicker with the Sprint Booster, but I have not really tested the outcome properly to actually say for a fact that my car accelerates quicker.

However, I understand that you believe that the sprint Booster does not do anything for the engine, but you are stating your opinion as a fact when in fact you never even purchased the item or used it I bet, let alone tested it to make such exact statements about the product.

Good new I have one , that why I said an exhaust you could hear, when you change modes you can fell and hear it. I drive in manual mode it aides in downshifting also. BUT it's all good , in my opinion we are all family, God bless.

Hello Carguy. To clarify, the sprintbooster is a voltage regulator device. It will amplify the voltage it receives from pedal depression, and therefore advance the throttle response in respect to pedal depression. Thereby, decreasing the amount of pedal travel required to attain a higher throttle. Hence, if your stock pedal depression at 75% gives you 75% throttle response, with the sprintbooster, it will now give you 100% throttle response. That's the entire purpose of this device. Factually, it has no other effect on the vehicle except for decreasing the distance required of the pedal to attain a higher level of throttle. That being said, if it makes your car more fun to drive, then that's great. I personally have nothing against SBs.

I'm going to agree to disagree, I understand that the basis of what you are saying is true, if I'm going to run big boost, I would need a dyno tune, what I need in my opinion is a way for more fuel and 8 psi of boost. I feel like people want to kill everything in stead of shooting everything down let's find a solution. But ,Never a solution just a roadblock that's the reason why nobody makes anything for our cars. Look at pass post it's always what we can't do never what we can. Just my two cents, I hope I haven't offended anyone , I just want more power. And how does a community get this way? Nothing worthwhile is easy or simple together we are strong divided we are week.

Huh? I think you are confusing a SprintBooster vs an ECU tune. A sprintbooster is as I stated in my last post. An ECU tune is a completely different, and viable/necessary modification depending on your application.

I have both sir. , I was also responding to edizzle89 post. My bad. I ran them but together.

Again, you provide a simple explanation of the Sprint Booster concept. However, more factors come into play such as the manner in which the stock throttle opens the throttle plate. Many OEM drive by wire systems opens the throttle in a gradual rate regardless of the throttle position based on the throttle sensor voltage data. Having the throttle open fully at a lesser time does increase acceleration performance. Just try to put your Genesis in ECO mode and test it against Sport mode in stock form. The Sport mode setting allows the throttle to open at a more linear manner than the ECO mode, however it still have a delay until it opens the throttle 100 percent to provide a smoother/safer driving experience.

The Sprint Booster just gives the Genesis a Track mode in a sense that makes the pedal to throttle plate opening more a 1:1 where as the throttle opens to about 100 percent from the initial press of the pedal. Very dangerous to be honest unless you are on a track.

Trust me, I own the Sprint Booster and it does make my Genesis accelerate quicker than even the stock Sport mode.

No offense but you are making statements based only on subjective data(opinion, theories,untested) you read from the web, have you even tried the Sprint Booster in your Genesis? My information is more from observational and subjective data. However, I will do data logging to hopefully apply some tested data to my observational data.

I'm not trying to kill your idea, I just dont want you to go into it with false hope and blow your engine up. I have no doubt our engines can take 8 psi, pretty much any engine can, but just adding bigger injectors/fuel pump without a tune will cause issues, not having a MAP sensor that can see positive pressure will cause issues, not having the ECU retard ignition timing when the boost comes on will cause issues. I'm just saying there is much more do doing it right then just adding a N/A tune and some bigger injectors/fuel pump.

Because if you are the first person to try it and dont take the time to actually do it correctly and it blows up, that will make people think it's not possible. I am all for pushing the envelope but you cant cut corners. Obviously BTR can tune our cars, if you wanna turbo your car then I would work with them to see if they could do a custom tune for you, but that would probably require going to there shop and doing dyno runs
 
I respect everything you are saying, I also appreciate your input, clearly you are very knowledgeable, they are other alternatives, stand alone computers, but I coincide ,you guys WIN, I will keep my thoughts to myself,so much is said to stop progress, my tune is a stop gap ,but it's a start, we have to start somewhere, why not now? I did hear you say you all in for taking it to the next level! Help me crap help us, if I was your son would you shut me down or help me? I get It I might be the only one who want more power, maybe I should of bought a dodge charger, I didn't I bought a Hyundai Genesis Rspec Sedan and I love it, it deserves to chew bubble gum and kick ass, and we my friend are all out of bubble gum. Good day sir good day.
I apologize for the theatrics, thank you,truly for you time,comments and imput. I'm just salty because I see the surprise look on people's faeces when I shift to manual mode and you hear the crackles of the exhaust and they see that they can't catch you until the next light or you slow down is awesome I beat a guy so bad he bought me breakfast just to talk about the car, beat a guy in a ram truck wanted to know what size engine I had and said I have a scat pack that might give you a run for your money. NO ONE NOTICE THE CAR UNTIL THE TUNE AND EXHAUST I'M A WANTED MAN NOW! LOL. I started down the dark path of modifying, now I'm a addict !! Trading ,buying, or selling is not a opinion for me. I don't regret my purchase. God bless you all.
 
Guys Y'all are so quick to hate because of the lack of a large power jump... Something not feasible on a NA engine... If I wanted a fast car that would run 9 second quarter miles I wouldn't be driving a LUXURY sedan. The tune for me would be a change in driving experience. Higher redline w my cat back would sound amazing! Pair that with an incorporated pop and bang tune and it would be an orgasmic exhaust tone... the paddle shifters would actually be useful with the auto up shift and restricted downshift eliminated. And ecs fully off with tc would make some fun days in the wet/ snow covered pad... In my opinion the 950 (850 with current discounts) for a new ECU with an ECU+TCU tune is not terribly bad considering you can switch between ecu's when taking it in to the dealer.

And for the record I was asking for the opinion of owners who have the tune. MR.KMAN33 was expressing his experience with the tune, as per the question posted in the thread and I appreciate the feedback. God Bless.

My pleasure thank you for the support, if you have any questions or your in the Dallas Texas area ,I'll take you for a test drive heck I'd even let you drive my baby. Lol thanks again, and continued Blessing.
 
Do the mods for the coupe work with the 3.8 sedan? I’ve been dying to put more into mine!
 
I'd try the pedal commander thing on my 5.0 - but I'm afraid that it would make my transmission explode... as it's living on borrowed time anyway.
