Thirteen months and no issues thus far!

Glad it's working for so many.

Does the wire diameter determine the stiffness of the spring? I used the 0.47 as suggested but still find it a bit soft for my liking. That being said, my ankle is much happier now!
Shortening the spring a little will increase the tension

Thanks again polaski!!
BTW, can you give us more detail about fuel consumption now that you had a good year with this?

Brilliant. I will give that a try before I buy another spring.

Polaski,

I am having a difficult time locating 5 x 3/8 x 0.047 spring but I did found a 6 x 3/8 x 0.047. Would it be better to find one shorter or longer than 5?

Hey Robert, You can shorten the 6" spring to 5" with some fairly heavy duty wire cutters, a grinder, Dremel MotoTool or the corner of a file edge.... Needle nose pliers can be used to fashion a loop to put the hook through.

After using the 5" one for a bit I found it too strong and went to a softer maybe longer one so the 6 may work. I guess a lot of it is up to the feel on the pedal we each have. I tend to forget until I see this thread that I made this mod.

Not really. The car still gets 34-36 mpg driving locally and about 38-42 if I take a long trip. I've become lazy anyways as I use the cruise all the time. Sometimes I wonder how I put 80k on my last car without it. The fit is much happier when cruising down the highway now that the valves are set so I can't really compare before/after.

I do know that if I drive a toyota which seems to have the softest accelerators known to man I have a problem of flooring it unintentionally because I'm so used to the fit+spring. Not good with that 5.7L...

Found the exact parts used at Ace, completed in under 20 min. It's brilliant!

Almost 18 months and I might have had my cruise on for an hour total time since... I was having cramps along my shin bone from having to constantly work those muscles to not put too much pressure on the gas pedal but that crap is history since I did the fix. Now I need to figure out how to do the Polanski A/C thermistor fix before summer rolls around again.. I have always messed up doing anything that involves wiring.

It's not that hard... just don't fry the resistor! I was going to send you one from my spare parts, but I wound up frying them... the only working one (out of 5!) went into the fit.

man... had my '10 Sport for 4 days now and this was the first thing I HAD to do! What a difference!!

My foot was hitting the spring when mounted normally, so I had to raise it higher on the rod. I had to put two black zip-ties on there to keep the S-hook from sliding down to the pedal. Since the spring has a lot less leverage up there, I also had to shorten the spring a bit; I put the top S-hook into the spring about 1/3 of the way down... basically pre-loading the spring a bit.

Now it's perfect... spring is way out of the way, and perfect amount of push on the pedal!!!


Here are a couple shots (sorry for the size)

I think that's why the original calls for shrink wrap tubing on the S-hook. The rubber is grippy enough to prevent it from sliding down.

Whiskey Six has me thinking of the USMC MOS 0341 or maybe an 08 MOS if I consider the 4.2mm mortar.

Thank you for posting this guys! I have had my 2010 Fit Sport for about a week and really didn't notice how soft the pedal was until I started to commute (100 mile r/t) and found it very uncomfortable on my right leg feeling fatigued all the time.

I think I will go to Lowes today and see if they have the springs mentioned here. I will buy both the 3 1/2 x 7/16 x.47 that DoubleR used and also the 4.5 x 15/32 x .41 that Stravos said he used and see which one is better for me. It almost looks easier to do this mod on the GE than the GD due to the placement of the hook under the dash



So really a big difference doing this mod huh? I hope so because I really like the Fit but the gas pedal might be a deal breaker for me due to my commute

yep - really a great mod; you won't be disappointed.

The nice thing is that the tension is adjustable just by hooking the spring in the middle rather than the end (see this pic)... You can make it as stiff as you want.

They're called Tension Springs. I have no idea where they are, every store is laid out a little different. They are used on the old fashioned screen doors of yore.
