Best Throttle mod ever

Want to improve your first gear take off? Want to get rid of that annoying dead-spot in your gas pedal? Do you have 10 minutes and a Phillips screwdriver? Then i have a mod for you.

First off i own a 2010 Forte SX sedan and i hated how the gas and clutch worked. Over reving the engine or stalling at the lights was a pain in my $&%^!!!

The gas pedal works by wire, no cable. The fix involves loosening 5 Phillips screws on the left side of the gas pedal. The screws hold the pick ups for the sliders feeler arms. Once the its loosened it can be repositioned by moving it in 1 of 2 directions towards the front of the car or back. Front of car will take out the dead spot and to the rear will give you a HUGE dead-spot. The pic is upside down and only shows 3 of the 5 screws and where the the wire plugs into it.

I took my pedal rite out and was going to mod it but then i noticed that there was room to slide it instead of hacking it up.

Why do you need the ten inch extension?

i think i went too far lol... i noticed i went from 700-800rpm idle to constant 1000rpms

be sure to take your car out for a spin too not only let then engine but the tranny to fully warm up, drive it for about 20 minutes so everything is warmed up and idles at 750 rpm when at a stop, then you know your ready to do the mod, my engine idles at 1000rpm when its not fully warmed up

Finally did this mod tonight and it works great! I adjusted mine to read .94v and it's perfect.

I just did this mod last night. Seems better, but I only took it around the block and I need to get used to the new setting. I will report back on the drive to work today.

Did any of you have a screw that was painted black? Seems like it is to detect if we messed around with it.

I did this today and couldn't put the painted screw back in after it was adjusted? tried to move the sensor with it loosened, fail... had to remove it. Will this be an issue?

Thanks a TON Enviros... i also noticed this too. I'm a new 6 spd driver and I am having a hard time "blipping" the throttle for downshifting as I'm not getting to the revs fast enough (I still sometimes over-rev at the lights too) Hopefully this helps a bit.

Never knew that stuff like this can be done too. (not very mechanically incline either).

Thanks for your inquiring mind!

just did this got it down .92v pretty much no dead spot i can notice, gotta get use to it though cause im over revving a bit, just took out for another spin, seems like im getting the hang of it already, for thoughs doing this mod, if your use to your dead spot and driving manual, just becarefull the difference is pretty major, so feather the gas until your fully use to it! overall great mod!!

one question im lazy to go back and read, but do i have to put the set screw back in? cause im having trouble putting it back so i just left it without it, or should i say with it half way out


oh and heres a tip, loosen the 4 screws leaving the set screw last to loosen, because you DONT have to loosen the set screw THAT much as shown in the video!

OH and one more tip! when your reading the voltage and your cramped under there be sure not to have your arm resting on the gas pedal even just slightly!! it will read higher, i made this mistake where i kept adjusting it, had it set, tighten it then it went back to .78v, that was because it was at .78 the whole time but my arm pressing on the gas a bit made it say .97 LOL!! so just be SURE not to touch the gas AT ALL

sorry for the blabbering

I have been driving it around for awhile now, and it is way better! Thanks enviros!

Mine ended up at .97 I find it a little too close, but I don't feel like getting back under there right now. I have sore ribs from lying on my side over the door sill.

By the way, unbolt the pedal! It's so much easier. I don't know how you guys managed to loosen and tighten those screws with out removing it.

I did this today without taking the part off and with the car running to watch the revs.. While doing I pushed it all the way forward but no change in revs. So then I decided to tap the pedal to see if it was improving. I thought I seen an improvement between forward and backwards.. So I screwed everything back in and got in the car.. Gearbox light was on and I couldn't figure out why. I turned it off and on but it was still on. Since my dealership was a mile away I drove it down there with no problems whatsoever. Me not thinking that it was sunday and no mechanics work on sundays lol.. I got there walked inside and someone from sales went out to look at it. When I turned the car back on the light was gone.. WEIRD. I don't see much of a difference in response but I'm not to sure if I did it right in the first place lol.

Has anyone had a problem with a consistently high idle after they did this mod properly? My friend (lead tech for Audi) and I set the throttle adjustment at .934 and all seemed fine for two weeks...
until last week when my idle started out at about 1500 and took about 10mins to get down to 700.
it's continued to act like this since. were going to get a reading again tomorrow to see if it moved. other than that any ideas?

Newbie reporting in.

Just did this mod about 10 minutes ago, didn't have tools to remove gas pedal though. I'm not even gonna bullshit people considering this mod. If you don't have the tools to remove the gas pedal, GET THEM. I'm a big guy myself, 6'1" large frame. I am SORE from having to contort and twist and bend to position myself properly to do this. And all that is just from loosening the screws and re-tightening them. The actual mod took me about 30 seconds. Positioned it right at 1.00 on the first try, was down to 0.95 after tightening. Deadspace on accelerator GONE!

i'm too lazy to check out the first post.haha. what's the purpose of this? work for automatic? right now the gas pedal is a bit touchy.
 
#253 ·
#252 · (Edited)
For an automatic like ours, the benefit is not as great as on the manual. You know that half inch to 3/4 inch of freeplay in your accelerator? How it doesn't IMMEDIATELY respond to the lightest touch? It gets rid of that.

It's more important for a manual because that 1/2 inch to 3/4 inch of freeplay is what's screwing everyone up and making them stall so much.

Hey guys, got a problem here, just did the throttle mod, everything went good, but when i drove my car, the check engine light is on and also, on first gear, when i pass 20 km/h the motor drop (revs) I really don't know what to do, I adjusted the sensor to 0.9v.

I have a 2012 forte koup ex maual



any ideas why?

first post!! hi guys this is my first post on forte forums. very nice site. ive hated the throttle in my koup 2.0 6 speed manual since i bought it, the car drives like a dream when up in speed take off's i dont find too bad but 1st - 2nd gear shifts make the car feel lazy like hesitant for a second, also 2nd - 1st gear shifts is basically impossible to get right, even driving in a parking lot when im just triing to feather the gas the car surges then lets off, it almost gives u whip lash sometimes it gets so bad. do u think this has to do with this throttle mod? if so then im definitly going to try it cause its beginng to drive me insane!! its fine in the country where i live but when i get into the city with traffic lights and tight parking lots its bad.

thanks for the help and very great write up on this throttle mod!

Does this mod have any effect on gas mileage; negative or positive? Damn, I've been asking a lot of questions lately. xD
 
#259 ·
No effect on gas mileage. I did mine months ago and still get the same 30mpg. It's worth doing, it's a subtle difference, but makes life easier when it comes to shifting.
 
#260 ·
Rumles, sorry, but I got a bit confused, have you done the throttle mod and are asking if all of the things you described have to do with it, or if doing it will help alleviate those things?
KoupEsEcks, have to ask questions to find out what you don't know. ;) Unlike Walpole though, I actually did notice a small difference in gas mileage. Then again, it may just be me. LOL
