I plan on buying a throttle controller which should eliminate most if not all of the responsiveness problem, at the same time this is a great answer Type 100, I'll amit that sometimes I don't pay attention to how quick i'm shifting but rather things like when I'm shifting and just watching the speedo and tach climb. I have the Mugen shift kit so I'm not sure how that compares to the stock unit, but throwing quicker shifts definitely helps acceleration.

 

broody you must have not driven or went for a ride in a Fit with a throttle controller. It is a world of difference for the Fit, at least in the GE8, can't speak for the GD model, but TC I know approves of it in his. The DBW is not really an issue whatsoever, hell even my Snisen prior to the Fit was DBW and it really didn't have issues, though I can say the Fit's DBW is better than that of the Snisen. The Snisen really came to life after I installed KPro and tweaked. Prior to that it would be somewhat dull on steep inclines starting from a stop. Anyways, my TC stays on SP7 at all times and the Fit is a much more fun to drive vehicle with it. Also can't speak for how it is with the AT equipped models, but the OP has a manual so he/she should really look into picking up a throttle controller and I have no doubt that the drive will feel vastly improved in the acceleration aspect of the car.

 

But those TC thruly make a faster response, or they mostly just throw more gas for the same input? Also, what I didlike of the DBW is the smoothness, is it still smooth?

 

They don't throw more gas...it's a change of throttle % pushed.

And yes...it's smooth!

 

Then it's pointless.
Carb + lightweight flywheel is the perfect combo.

I don't get the appeal of "throttle controllers". All it saves is not having to push the pedal as far to get the same power output. There may be some perceived difference as a result, but 0-60 is still the same. It may reduce the ability to control the car by having less pedal travel.

It's not a throttle "controller" so much as a variable gain modifying the input from the accelerator pedal. Torque and HP curves are unchanged and remain entirely under the control of the ECU.

With all the talk about run-away cars and DBW being questionable (not that I'm concerned about either), it seems ill advised to place a cheap 3rd party black box between your car's accelerator pedal and the ECU. If it toasts your ECU that's an expensive replacement.

 

Steve have you driven a fit with an etc? It's about making it more enjoyable.

 

Nope. Don't need to deceive my foot that it's faster.

 

Ah well, I guarantee that if you tried it--you'd think differently. It's way more fun.

 

I get my kicks in my wife's solstice gxp. When she's not in the car. It's silly fast, 0-60 in about 4 seconds.

We did pay for a factory tune that increased HP and torque about 10% across the spectrum. That cost about $500.00. I'm not against paying for performance, when there's an actual gain in performance. It needs better tires, shocks, springs, the works. Someday (she'll probably get tired of it before then).

 

The first time I experienced the effects of a throttle controller was in a Lexus in the early 90s... In luxury cars of that sort it is called sport mode and is a standard feature.... The people that don't get it are missing out on a great product.... It has the same effect as a large spool throttle on a motorcycle.... It doesn't just change the position of the the pedal in relation to the throttle opening but the speed of response.

 

I don't know Texas C I tend to agree with Steve on this one...I highly doubt a TC is going to make any difference in acceleration times. We need some unbiased testing done!

 

You may be right when I think about it. 1st and 2nd gear wheel spin can be a problem at times using the SP7 mode. I don't get it, people drive a stock Fit, install a part that improves performance and shares their experience.... Another person drives a stock Fit, has no experience with the product and therefore no idea in the world what they are talking about and you agree with him.... I wish you well, life can be difficult... Be nice and maybe someone will let you drive their car that has one installed on it.... There are many threads since Blitz first sold their T/Cs on here and people loved them for the performance gains.. JDM Chris evaluated Panson's ETC in both Sp and Ec substantiating that it performed as well as the Blitz in SP and also gave him a 10% boost in fuel mileage in the ec5 setting.... My car is just too strong in sp7 mode except when I want to get around a line of slow moving traffic on a two lane highway and I usually drive in the ec5 mode to conserve fuel.

 

But why don't they make it response fast even normaly?
I don't get how a slow response will help to be more fuel efficient. the slow response will just make you acceleration .1 second later...
I like to instantly feel every throttle input, not .1 second later or all "smoothened".

Technologies like dbw are supposed to make cars better, and I don't see why we would have to pay 300$ or so to fix something in a 15k$ brand new car, when it wasn't an issue 10 years ago. They made it wrong, they should fix it for free with a recall.

 

the "throttle controller" is just a circuit (amplifier?) put between the accelerator pedal "pick-up" (it's probably a rheostat, I don't think it's digital) and the ECU. It doesn't make the ECU or throttle behave any differently, just the pedal.

If it makes it seem faster, a lot of people will buy it.

When I want to go faster, I push the pedal farther. It's not rocket science.

 

i rev 4K+ and quickly engage clutch (not dump) and floor it as soon as the clutch and tire clamps hard. this is why i like MT on these under powered cars. you cant do this on AT and miss out on a lot of opportunities.

 

The $300 circuit people are buying just makes the throttle move more in relation to pedal movement. Push the pedal a little and the throttle opens a lot. Normally without the circuit; push a little, throttle opens a little. Which is better? I think saving $300 is better. Want to open the throttle completely? floor it.

This kind of customization would have been done by altering the mechanical linkage to the throttle before DBW. Was this a frequent mod before DBW? I'm guessing not as problems would be hard to engineer out; it's easier to mod a electrical signal by amplifying or attenuating it a bit. $300 is high for what it does.

 

I'm gonna guess "sport mode" on Lexus in the early 90's was a different shift profile on their auto transmissions. I doubt they had DBW then, and wouldn't have an easy way to alter throttle behavior based on pedal position. Please prove me wrong.

"speed of response"? If the throttle plate moves faster in relation to the movement of a mechanical throttle hand control, it moves more. Think about it.

If there is latency on Fits' DBW throttle, delay in throttle movement after movement of the accelerator pedal, an aftermarket electronic device between the pedal and the ECU will not change this. The ECU controls this; you'd need an aftermarket tune to change this (if not built into the hardware). I think there is some delay, at least in releasing the throttle: the so called throttle hang when releasing the accelerator pedal. Not sure about the other way. It seems to wake up immediately when I press the pedal.

 

The OP asked how to get faster acceleration from a dead stop and numerous people that have an ECT on their cars have offered using the same as a remedy for his problem... I can understand how in theory it may sound like it only provides the effect of an improvement in acceleration but in application it is a solution to the performance loss incurred by the DBW actuation of the throttle to lower emissions and improve fuel mileage as well as solving the problem referred to as rev hang when changing gears at high RPMs.... Mr Mahout has been driving in SCCA competition since the 1950s and has commented that a car that has a lower power to weight ratio than another car but builds revs more quickly can often out perform the more powerful car on the track and an ETC does make an engine pick up RPM more quickly.... J Crimson has an aluminum flywheel, close ratio gear set and lower final drive ratio on his car that he road races and he uses the same ETC in SP7 mode and setting on his drastically lightened car as those that have posted here... No one has made a claim of it being something that increases engine output but that it improves throttle response by allowing the throttle to open more quickly or improve fuel mileage by allowing the to be modulated more precisely at the expense of much slower response than SP7. I have no idea why people think the ECT we are talking about cost $300 I believe that Panson sells them for around 1/2 that much or maybe less.

 

Reducing the mass of the turning parts is not the same as opening the throttle faster.

HP/Torque remain unchanged when a so called throttle controller is added. Maybe it helps those with slow feet.
