I've recently changed from a 2002 STI to a 2007 (Hawkeye) STI and one of the most difficult differences to get used to is the extremely light electronic accelerator pedal in the 2007 model. Its so light that every bump in our terrible roads (NI) has my foot bouncing up and down causing the motor to kangaroo. I'm actually getting a sore leg holding my foot up!

Has anyone else noticed this? and has anyone investigated installing a heavier spring to give a bit more weight to the pedal?

 

Yes I have noticed it, no I don't really like it, no I haven't seen a solution.

Probably my biggest annoyance bar the seats. I have a classic too and much prefer a cable.

 

WOT FTW !

Seriously though the throttle sensitivity map can be changed when mapping if a stronger spring cant be added.

 

I much prefer the cable system. I'm going to look into a heavier spring for this electronic one.

Agree on the seats! Why change something thats perfect? The 2002 seats were much better. The 2007 seats are too wide, dont hold you as well, too low at the front and the height adjuster is a joke - only pumping up the rear seat height!

 

I appreciate that this is a basically maintenance free system and it is technologically FTW however they should have added a bit more weight to it for those of us who don't have twinkle toes Maybe I'm just loosing my fine motor skills in my old age! I can't play the PS3 anymore either

 

I was told, and this might be wrong, as has been the case with alot of what I was told be this particular person, but when turning the car on don't touch the accelerator as it calibrates on start up ?

Sometimes my throttle is too sensitive other times too much play. It's never been a real problem but for preference I prefer the feedback you get from cable.

 

It does do some calibration when you first reset the ecu but I havent checked for a while as to whether it does this everytime you start the vehicle.

You shouldnt need to touch the accelerator on start.

 

WOT FTW ! Flatshifting FTW

 

I have got to agree with the aching right leg... got to be honest the lumber suport of the hawkeyes seats are better than the 04 model albeit it doesn't hold you as good.

 

i cant agree with you more thats why im collecting a set of seats out of an 05 plate tonight , i cant wait to get the support and comfort back, i even had a set of brackets made for me by an engineering company to lift up the front of the drivers seat and they worked perfect they tilted the front of the seat up by about 20mm i paid £ 30 for them if any one wants to buy them they look factory fit and are in powder coat black and you can hardly see their there, dont ask me to put any pics up of them im crap with computors, cheers steve.

 

Sorry I have to disagree, I also have the electronic throttle but I have no issues with it! but I have never driven an older scoob so I cant compare.

 

I agree - it is a personal thing though. I like the DBW throttle feel.

On mine I have noticed that the throttle % can lift when going over bumps so I mapped that out by reducing the effective 100% down to say 80% to remove the symptoms of this.

 

What does the DBW stand for

 

Drive By Wire (electronic throttle basically) rather than cable driven.

 

Ditto to all that.
Driving through twenty mph speed hump areas is either first gear at 80% throttle then brake etc etc. or kangarrooing after every bump.
The shame is it will very happily pootle along in second on a flat road, but I guess the council know whats best
I do miss the seats in my 2002 blob as well. Leather seats in Spec are a waste of bloody time.

 

I'll give you the £30 for the seat adjuster brackets - no sweat. Anything to improve this seat. I think you PM me and I'll email you or something like that to get in touch. I too have considered getting seats from an 02. I'm not sure what year they introduced these wider seats. Maybe the folks who don't experience this have shorter legs Not that I'm a giant

 

The throttle % lifts when going over bumps coz ur foot is bouncing up and down on a pedal with a combination of too little resistance (spring weight) and too sensitive a response in respect to pedal travel.

Your solution is interesting. Does this mean that you have sacrificed the 80-100% throttle range, meaning that your physical pedal travel is now 0-80% throttle depressed to pressed full thereby providing a less sensitive response. ie more pedal movement required to get the equivalent % throttle?

If yes - then that sounds like exactly what I need done.

One question though is by sacrificing the 80-100% throttle range to you sacrifice top end acceleration in favour of bottom end comfort (less sensitivity)?

 

If you compress 100% throttle into 80% of the map then it will be more sensitive.
Ideally it needs rescaled to increase the non linear characteristics already present in the std map ie less sensitive at low throttle opening and more sensitive as the throttle opens further........ or add a spring !!!

I like mine
except under hard exceleration in 1st or 2nd then i can start to Kangaroo which dose not look cool!
if anyone finds a good spring lets us know

 

Yes. That is very similar to what I have done - the throttle map is now based on 80% and above pedal position equals full throttle. So if my foot is to the floor and I get a slight bump then the pedal position may changed to 90% for example but the throttle still keeps wide open. This was also a way of forcing myself to brake later on track

1st gear - I hardly ever use apart from pulling away or 1/4 miles and they arent really representative of real world driving.

With the DBW throttle you can make the car do whatever you like as far as sensitivity is conerned which is simply not possible with a cable throttle. Turning the sensitivity down in the low end for cruising is easy in exactly the way that Subaru has done with the three different throttle maps in the 08/09 STi. Look at the i mode throttle map versus the sports # and you can see things that are possible on DBW that couldnt be considered on cable throttles.

Adding a spring would be a good option for those that want the throttle stiffer but personally I like the weight of it as it is being a soft southerner

 

can you map a 06 WRX
and what could you achive with a map?
what cost for a throttle map ?

 

Yes.

It depends on what you want to achieve really.

Gimme a shout if you want to chat through.

 

Often spend a bit of time altering the dbw throttle to how the owner wants it, sometimes though the cable works better

 

I'm very interested to find out how to remap the throttle. I like the idea of being able to change it to suit the circumstances. Do you need a full electronic service tool? or is there a simpler version about for the likes of me who isn't interested in remapping for a living?

 

It would need to be done with a laptop and cable (and the right software).

 

althought iirc the multiple maps that are coming would allow different throttle response depending on the map you were on

Simon

 

I'm guessing they will be using variants of the requested torque tables Simon in the same way as the hatch STi does?

 

now that would be telling wouldn't it

 

Seat brackets now sold.

 

Hi simon (JGM) is it true that on a remap you can map it so that when you lift off the throttle you get a few pops and bangs from the exhaust, cheers steve.
