Sprint Booster

"Why in the world would you feel the need to do that?"


Really?

 

I'm glad you get it.

 

i don't have the booster, i have the pedal commander, but the answer is no, this does not alter the rev hang. it cannot alter it since it can only amplify the signal and not change ECU behavior.

 

Revving your engine is another form of blowing your horn a

Thanks for the reply. Being old school sometimes revving your engine at someone was a more polite alternative to blowing your horn. You can't tap that pedal 2 times real quick

 

I tend to disagree but only because ive noticed one anomaly in the stock programming. It seems that if you very quickly lift off of the gas pedal for upshifts the rev hang is not nearly as bad, and with that in mind the sprint booster amplifies the signal, so that even letting off the throttle a little gets you into that sweet spot where it drops quickly. I don't know what everyone elses experience is but I think the sprint booster helped with my rev hang quite a bit by killing the throttle a little quicker in between shifts and then getting back on the throttle faster after the shift as well. My girlfriend who rides in my truck with my every day has also commented multiple times that she feels like my truck can merge onto the highway quicker or accelerate to pass someone significantly quicker than before. I don't have any hard numbers to go off of but I tend to agree with her as far as the butt dyno is concerned FWIW. Its not a night and day difference, but if you drive the manual Taco and play with the sprint booster until you get good at rev matching again you'll see what I mean

 

The Rev hang does not change. It's a placebo effect.

As far as butt dyno, your truck is not any faster or more powerful. It is basically just pushing the gas pedal more which is why it feels that way. You have the same thing stock by just pushing gas pedal more.

 

That couldn't be further from the truth. First not only is it not physically possible to open the throttle as fast as the Sprint booster allows it to. Second that fact alone, compounded over the course of two or three gear shifts leads to probably a few tenths better acceleration but the biggest difference is accelerating out of a corner. Quicker throttle opening means faster acceleration but don't take it from me. With all due respect speak on it when you have driven a vehicle with one installed as I am sir. I can tell you there's more to it than just mashing the pedal quicker.
Also I never said it was faster or more powerful, it is quicker and more efficient in gear changes leading to better acceleration.

 

this may be a difference between the Booster and Commander methinks

 

After watching the video and hearing what the actual users had to say I went to the website to order but after seeing the cost of this I decided not to. The product seems great and I would love to have one but over pricing a product to get a quicker return on investment will keep a lot of people from purchasing your product. That just my $.02

 

Sorry bro you are straight wrong. 100% throttle is 100% throttle. The sprint booster does not change the motor on the throttle plate to a bigger one so that it moves faster. It does not reprogram the ecu. It takes the voltage from the TPS and amplifies it. That is all.

How is it quicker in gear changes? It doesn't do anything to the trans at all.

P. S. i have had one in my last 2 tacomas, and my current car. My old BMW had a similar system built in. Even with all that, it doesn't matter. It is science and common sense.

 

not sure what you're wanting but there is a code floating around here that will get you i think $40 off the PC. don't think the booster has a discount code, not sure. anyway, just so you know...

 

Third time's the charm eh? It makes the throttle REACT quicker, meaning it is quicker in gear changes because the revs have to DROP for a gear change. If you don't understand what I'm saying then there's not much point in continuing this. I'm not saying it has more horsepower or is faster or anything else. It reacts quicker so it is quicker in transition from no throttle to full throttle, and considerably so. Like the difference between riding a motorcycle with a shitty factory cvk carb to a nice aftermarket slide carb. It REACTS quicker so it is a bit quicker in acceleration. Not a 100% accurate comparison since different carbs can lead to different hp output, which is again NOT what I am implying, but the difference in throttle feel and reaction times hold up nonetheless.

 

who are you fighting with and what about? i'm confused, you didn't quote a post.

 

The one who broeth before he knoweth

 

lol

by the way i think the missing piece in that discussion is that, as reported by Orange Virus when looking into our throttle maps, it looks like our throttle maps do not actually provide 100% throttle at 100% throttle position. iirc they suggested about 80% only at 100% position. but anyway it was just from one of the early posts, not necessarily tight info yet.

 

One other thing we haven't mentioned yet is that this isn't a direct drive system. How far down you push the pedal does not necessarily mean the same thing as how open the throttle body is because of the drive by wire system. Sprint booster eliminates some of this difference by using a more aggressive map for the throttle position sensor, meaning the throttle is opened exponentially quicker, not linearly quicker as you are implying.

 

my experience driving the truck (with a PC, not a SB) is that this is absolutely true. the throttle control is the furthest thing from linear i've ever experienced in a vehicle. please OV, can you fix this?

 

Oh goodness. This is all the same exact shit that people argued about in the Pedal Commander thread I linked. You can find a video on YouTube that shows a throttle body and the direct affect of a controller like these. It does make a difference but IMO not worth it for the price or potential associated risk.

 

Thats quite the chip you have on your shoulder. Hope you are wearing a back brace.

Saying it is quicker from 0 to 100 throttle is only half true. It depends on how you set it up. If you set up a test where both trucks (with SB and without) have the throttle at 50% then yes the modded truck will "react" quicker because even though the throttle is at 50% the actual plate is at 65% (made up number just for example).

That being said, you can get an unmodded truck to do the same thing, you just have to give more skinny pedal to match.

Let me put it this way. If 2 trucks, one with SB and one without are set up next to each other both turned off, you hold the throttle all the way to the floor, then start both trucks the throttle plate will open at the exact same speed. SB doesnt change any physical aspect or reprogram the ecu in any way.

This again is not exactly correct. It does not react "quicker", it reacts more to less throttle input. It effectively shortens the throttle distance.

Again not correct. The SB does not modify the the ecu map in any way. The truck has absolutely no idea that you installed this device. It just makes the ECU think you are pushing the pedal more than you are. So no, the throttle plate does not open faster, it opens sooner in the pedal throw.

You are about 60% of the way there to understanding. Keep going you almost got it!!!

 

I never stated that the ecu map is linear. And I agree that it is not. That has no effect an how the sprint booster works or what it does. It changes the signal before it even reaches the ecu mapping.
