Hi Everyone,

With all the new cars having drive by wire gas pedels, it seems like it takes forever to get any response when you push the go pedel.

Well, its the same on most small cars with small displaced motors like the FIT.

I installed one of these "Sprint Boosters" on my Mini Cooper and what a difference ! It was like I had a real gas pedel with real response !


Here is the WEB site to check it out.

Home of Sprint Booster

Its a little pricy but I totally enjoyed my car once again after this Mod.

The install on my Mini took 10 to 15 minutes ........ check it out

 

I suspect you have never driven a car with mechanical linkage to the throttle.

I also suspect you're here to peddle a Chinese black-box to connect to the gas pedal sensor.

Why anyone would want some aftermarket box to alter the signal from the pedal to the ECU is beyond me. But lots of people think it's fun to get more throttle than their foot tells them they should, regardless of the loss of control, and possible damage to their car's electronics.

Carry on.

 

Unfortunately, there are no Sprint Booster electronic throttle body controllers available for the Fit. I believe that company in particular deals with primarily European imports (or at least I've seen).

However, in the Fit's case I believe Blitz and Pivot make an ETBC for the Fit. There is a vendor here who sells Pivot models, their screen name is twpanson and here is a link to one of the group by threads they have.

 

I thoroughly enjoyed my ETC while I had it.

Now with FlashPro I am able to re-write the logic controlling the Pedal vs. Plate Relationship.

TPColgett is running one of my new throttle maps, and has since done away with his ETC as well.

 

The electronic throttle controllers sold by twpanson work well as a means of improving your fuel mileage providing a choice of settings and a throttle position readout... I always use the slowest responding mode when on the highway to get more miles from a tank of fuel as well as on loose or slick surfaces when traction is bad to improve control... The faster opening performance settings will provide quicker throttle response.. It will get you moving faster when pulling off from a stop or when jockeying into another lane before the opening is closed by a jerk that thinks you don't need to be in front of him. ... Mine has been on my car for over three years and others have used theirs even longer with out it causing any problems..... Never take advice about anything from someone that is biased and formed an opinion without first hand experience....

 

So you would be willing to undergo castration even if I advise against it?

 

Is this like swapping out a cruise control throttle cable for a non-cruise cable? If so i'd be interested. Too bad I can't just pick this up for $20 at the junkyard like that

 

Aaanndd.. This is why no one takes you seriously, unless they don't know any better.

I'm still standing by my previous bit of advice for you

I got nearly 25k miles out of my ETC

 

I'm not sure I understand your question...

Before the day of electronic throttle control, all cars had a mechanical linkage, either a cable, or a rod, that connected the gas pedal to the throttle plate (either in a carburetor or throttle body if it was fuel injected).

Cruise control in those cars was a separate mechanical linkage, usually a cable from an actuator. The actuator was either vacuum powered or an electric motor. The controller module for cruise control was mechanical in early cars (think 60s, 70s) or electronic in later cars (80s, 90s). Mechanical cruise controllers required the speedometer cable be routed to its control box, and a new cable from the control box to the speedometer. Later electronic cruise control used magnetic pickups against the drive shaft (with magnets glued to the drive shaft) to sense car speed.

With electronic throttle control, introduced as a means of better controlling emissions (and necessary on hybrids) the throttle plate is moved by means of an electronic stepper motor. There is no longer any mechanical linkage between the gas pedal and the throttle. The gas pedal moves an electronic sensor that sends a signal to the ECU which in turn controls the opening and closing of the throttle plate.

Cruise control in these cars uses additional logic in the ECU to control the opening and closing of the throttle via the same stepper motor. No additional data is needed as car speed is already known by the ECU.

The so-called after-market electronic throttle controllers are overpriced circuits that you plug in between the gas pedal sensor and the ECU. They alter the signal to the ECU telling it the pedal has moved more than actual, resulting in more throttle than you expect. Alternatively in "fuel saving mode" it will move the throttle less than you expect. These are also prone to failure (some reports of sending Fits into fits (limp mode) are on this website.)

DSM has a GD for which aftermarket ECU flashing software and interfaces exist. He advocates altering the factory program to alter the mapping of the gas pedal sensor to throttle opening. This makes a lot more sense than corrupting the signal, but I don't think this software/interface exists for GEs (think hondata flashpro).

What was your question?

 

I think you'll get better performance with castration.

 

Speaking from experience for a change?

 

no no, just bias. Trust me.

 

That was quite an explanation.

That actuator box for cruise control killed throttle response on the few cars I had that had one (that or it was just old), swapping the cable out for a non-cruise cable made a night and day difference and was the best $20 I ever spent. I assume this will probably be the same feeling, just modernized.

My post was strange, I apologize, passing thoughts, it's been a long week.

 

Think of it as viagra for your gas pedal. If you have good foot control there's no need for it.

 

At least on the cars I've owned with cable-operated throttles, the segment on the carb/throttle body had two grooves—one of which was for the cable from the gas pedal, and the other for a separate cable from the cruise control unit. Pressing the gas pedal didn't cause the cruise cable to do anything (or at least didn't move it in its sheath; it does flex a little in the vicinity of the segment).

I guess the car you had must have used a different setup, where the gas pedal cable went to the cruise control unit, and then a single cable from there to the throttle? Otherwise, I can't make sense out of what you wrote.

With the drive-by-wire systems, your options are rather different. The typical boxes available just lie about where the gas pedal is in its travel, which makes it more or less sensitive to begin with, but don't intrinsically alter the throttle response time—just one's perception of things, which is perhaps good enough for most things. Altering the programming of the ECU, as DSM suggests, does give a lot more actual adjustment, but has its own challenges and possible difficulties. I suppose one could alter the response of the throttle actuator somehow (whether electronically or mechanically), but that would presumably throw the ECU into a complete tizzy and lead to all sorts of difficulties.

On the other hand, altering the physical feel or location of the pedal has never been easier.

 

Correct, both Toyotas

Removing box also saved 3 lbs

I have no complaints about the throttle in the Fit, I can blip, rev-match, pretty much do whatever I need to without difficulty, I am however curious about this device and how it would finally make my life complete.

Wish there was a try before you buy program.

 

Steve244,

No I am not trying to sell the Sprint Booster but I am trying to let the members here know about it. I have been driving for 44 years so yes I know all about cars and gas pedals.
You on the other hand may have never tried this product so you really can't comment as to its positive results to the purchaser.
I installed it to remove the lifeless feel of my electronic gas pedal and to me it is an improvement.
Each person here is only attempting to express positive comments, not force people to think their way is the best, and the only way of thinking.

 

Honestly, I don't notice a delay at all in the fit. The only thing I notice is the obvious rev hang after pressing in the clutch.

In my last vehicle, a jeep patriot, there was an obvious lag from the electronic throttle. It would actually f up some times, and have no response at all until you let off and pressed the pedal again. That wasn't fun when you were trying to merge into traffic.

 

I haven't been to your website (sorry, biased) but someone mentioned up thread that your device isn't listed for Fits. Try again.

 

Based on the site info it appears to be available ............................... and it can be returned within 30 days
