Anyone know of a way to tighten up the throttle lag? I have heard of devices like Sprint Booster, Pedal Commander, and Ultimate Control... thoughts?

Not sure what throttle lag you're referring to, but this is an economy car.

Maybe try getting something faster?

Google “Sprint Booster” to see what I’m referring to. Not looking to make the car faster.

I read about Sprint Booster and frankly it sounds bogus to me. Have you ever tried one?


A simple thing you can do to make the Elantra quite a bit more responsive is put the automatic tranny in Sport mode.

I have a similar device to the Sprint Booster on my Gen Coupe. It's a Tros Potent Booster and half the price of the Sprint.

It is amazing and should be the first mod someone does no matter what the car. It will make the throttle as reactive as you can stand. It is easly changed on the go if you want.

I get better gas mileage too as you do not hardly use as much actual gas pedal movement with it on.

I have Sprint Booster installed on my car for about a month now. Before purchased, I was skeptical as well, but after watching videos, and reading reviews, I decided to give it a try (30 days money back guarantee). I have no regrets of buying it. The car is responding much quicker on take off and when needs to speed up while driving(to pass..., or to merge into...). I have a company vehicle for daily driving and use my car mostly on weekends. So, I still on the process of finding the right mode on selector button without compromising fuel economy. First, I set SB on Sport-5, then tried it on Race-9, and it really feels like you are in different category of cars. Now I backed down to a Sport-9 selector for more moderate acceleration.
So, please, do not install this kind of stuff on your car; it may change your driving habits wrong way.

I really don't see how boosting the accelerator profile could improve gas mileage. The opposite tends to be true, ie reducing acceleration and staying in lower gears longer improves gas mileage; it's called ECO mode and it makes the car pretty sluggish.

Mine is a 2019 manual transmission. And they don’t come with mode select...

Any affect on insurance?

My insurance company says it's a performance modification (no different than adding a turbo), even though it does nothing for HP. It's essentially putting the car in a "sport mode" and leaving it there. I explained to them that the A/T variant has Drive Mode Select and therefore the ability to change to a different throttle response natively from the factory but they said that if I get an aftermarket part to do the same (even if it's installed by the dealer) it will void the warranty.

Pretty much a function of them not understanding cars (the guy I spoke to didn't know what a throttle body was), but I digress...

Regarding drive modes, eg ECO and Sport, they clearly change the automatic transmission's rpm shift points, but I don't know about throttle response - perhaps someone here can weigh in on that?


Regarding whether or not installing a Sprint Booster would void the car's warranty I would ask the dealer.

I drive several vehicles with lag, diesels with serious turbo lag. I can honestly say that what some may mistake for lag in the elantra is simply a lack of low end torque which is a result of the adkinson cycle. I'm on my 2nd Elantra. First was a '17 model.

The low-end torque (although weak) is there. You can notice a distinct delay when applying gas before the car moves. For example, you cannot easily "burnout" an Elantra as the ECU gently applies acceleration as opposed to FOT.

Drive-by-wire time delay is a real thing.
When you push the go pedal you're sending a signal to the engine computer, nothing more.
The computer takes consideration of the current running conditions, which takes time.
Of course some computers are faster than others.

A calculation is made based on engine speed, present load and more, then the throttle plate opened at a controlled rate, and fuel delivery adjusted, but they must track to keep the air/fuel ratio in control during that fraction of a second transient.
Otherwise the engine will put out puffs of excessive emissions every time the throttle is moved.
Carburetors were very sloppy at this, with their accelerator pumps.
At one time in California some cars were not sold with 5-speed manual trans, only 4-speed because the extra shifting made them fail the emissions regs.


Anyway on my previous car (2006 Toyota Matrix) I could demonstrate DBW lag by giving the throttle a quick jab (in neutral).
I could get my foot on and off the pedal before the engine would rev up about a 1/4 second later.


Those throttle enhancers simply make the throttle signal to the computer bigger, and/or add a time differential factor to the signal, to make it seem like the pedal is moving faster.
They cannot reduce computation lag.

This may or may not apply to your Elantra, but give it a try: Before I purchased Elantra Sport, I was driving 15 Elantra GLS 6speed manual gearbox. The ECU, mostly in sub-zero temperatures (I see you are from Edmonton as well), cut the throttle every time it sensed even slightest wheel spin. My solution was to disable the traction control button (single press). The vehicle became lively and allowed normal (for me) driving. While this feature may be helpful to new or unskilled drivers in slippery/winter driving conditions, for an experienced driver it is a nuisance, as the car refuses to move when the throttle is depressed.

Does turning off traction control also effect ESC (electronic stability control)? I won't be trying this.

No, it only allows for the wheel spin. ESC is not affected, unless you press and hold traction control button for more than 5 seconds (if I recall properly).

You need to get one of theses. Easy to install, easy to program, many different modes. It will transform your car and the first month you will be driving with a huge grin on your face. After using it for some time you don't even notice it until you shut it off. It should get you a bit better gas mileage too as you are much gentler with the throttle.

Is it similar to the Sprint Booster? Do you remove the gas pedal to install?


How much was it? Do you know if they ship to Canada?


Cheers
