Title: G25/27 GTEYE spring mod
Post by: marty on June 06, 2014, 12:41:07 PM
There was some discussion about this in teamspeak chat in the Thursday nite races so I will post a link for those using these pedal sets. Highly recommend it as it gives much more feel then the stock springs, may be time to upgrade mine to some load cells but with this I can control brake pressure quite well.

They are based in Melbourne as when I ordered it it came hand delivered seeing I live only a couple suburbs away from where they are.

I have this spring mod and find it really good. I have struggled to improve my pace and braking was my biggest challenge. Since installing this spring I can feel the brake pressure/threshold and am now able to adjust the brake balance and, in AC, the brake gamma so that I am not locking and spinning all the time. With AC I have been able to adjust the gamma so that the spring pressure point (which is non-linear with the GTEYE) matches the non-linear gamma curve set in AC. So, like a real brake, I can push the pedal to the "resistence point" and then control the brake threshold through pressure on the pedal.

I did the Gteye spring upgrade previously in my G25 and it is better however I then went to a load cell from Ricmotec
http://www.ricmotech.com/Load_Cell_Upgrade_Kit_for_Logitech_G25_G27_Pedals_p/rmt-lc27.htm (http://www.ricmotech.com/Load_Cell_Upgrade_Kit_for_Logitech_G25_G27_Pedals_p/rmt-lc27.htm)

It totally changes things.  Small amount of travel and a hard pedal which totally relies on pressure in the same way your
car does.  Initially you will find the pedal to be pretty hard but you soon adjust and the control over braking is much better.
Definately worth the $109 US + delivery, unless you want to buy a complete new set of pedals with load cell included for twice as much.

Just out of interest, Freezer, are you a left-foot braker, or right?

I can vouch for the GTEye.  Best bang-for-buck mod around and very much makes braking a lot less of a lottery than with a standard linear spring pedal.

Hm, ok...I was and still am afraid of a load cell setup a bit, due to the exact same thing, I just can't RFB in-game.  But then I can't LFB in the real car.  (well I can but it feels wrong and the result is not ideal either :) )

But I'm not suggesting that my left foot braking with the load cell is an issue.... its not.  You get very precise feel and control with the load cell, rather than just a heavier pedal that the spring gives.

I am the same as others - cannot left foot brake in a real car but left foot brake in-game. It could be that most cars are not setup for left foot braking. Here's a picture of a car (an SUV!?) that is offered only with a semi-auto box (no manual option) and is definitely designed to allow both left and right foot braking.

Hey guys,

Just bought and installed the GTeye. Great customer service by the way. eBay'd it on Monday and it arrived on Wednesday. Can't complain about that.

I am now trying to fine tune the Gamma and dead zone settings in AC and it's a real pain to have to leave the car, close the session, go back to the setting menu, make a change and then back into the car to try out the changes.

Just wondering if you guys could give me some idea of what settings you use in AC to at least get me close as a starting point. I realize we all drive differently and the setting will be very personal, but it would be handy to at least get a range of settings that other people are using.

Thanks
rob

From memory about 2.9 for me. I also set brake bias to about 70-75 when available. This seems to allow me to push the brake pedal right to the compression point of the spring without lockup. I can the feel the threshold via pressure on the pedal.

Hey thanks heaps for the G27 assistance last night Gratulin! feels a lot better now.

Your welcome. AC has been the easiest and the best wheel setup of all the sims I've tried. NetKar was the best feel previously of course but it was quite brutal if you 'oversteered' the car - for me anyway....

Post by: Rolz on June 26, 2014, 02:01:15 PM

ok talked me into it... I've ordered one... might give me more control rather than the gentle big toe push I've been doing to get the balance right...  :P

Anyone splurge out on one of these bad boys?

One other thing with brakes in AC. There may be a random bug with the braking that needs the brake pressure to be fully depressed while in the pits from time to time. Not sure why it happens but occasionally I go out on track and the brakes are locking up with the slightest touch of the pedal. If I go back into the pits and do the "depress brake pedal fully" thing it returns to normal.

I have the GTeye spring, it is great, much improved and easier to modulate ABS, i left the gamma as it was.

Gratulin, the brakes on the g27 and g25 need to be depressed fully after powering on to initialise them an set the range, otherwise you get 100% for the little you press.. is that what you mean?

Yep. Perhaps you don't get 100% but definitely very sensitive. But not all the time and not necessarily for everyone?

Well, my knees aren't getting any better so after using the GTEye spring mod I put my original G27 brake spring back  in.

I'm not sure if it's because I'm not used to it, but I don't know how you guys drive with the normal spring...  with the GTEye I instinctively knew where the lock-up point was before I was there.  But with the normal spring it's like you have to lock-up to know where the threshold is.  It's terrible.

But, I think I'm going to have to get used to it because my knees are screwed and it's either give up on racing sims or use the original spring.  Not sure what else I can do.

Have you tried moving the pedals laterally? ???
I get knee troubles having my legs at certain angles, noticable in different cars.

I've tried backwards, forwards and side to side.  Doesn't seem to make a difference :(

Strange as I find the spring a little stiffer and much better for feel, but still nothing compared to any real cars. Sure Ive done more laps on the g25 then in real cars on track but its a bit weird your having so many issues with it.

Is it from a past knee injury that yours are effected so bad, maybe try adjust your seat position as it could just be your leg in a weird angle more then the stiffer spring.

Would be a bastard going back to stock spring but better pedals with load cells would surely be even worse for you then the modded g25. Do you get any issues driving the real car on long trips too or is it purely sim racing that stuffs your knee?

Never had any knee issues before.  And that's after years of cricket and various other sports.

Might go to a physio and tell him/her how intense sim racing is!

Have you tried raising the pedals?

The pedals are on the floor under my desk and I'm using an office chair.  I'm using a WheelStand Pro which I attach the pedals and wheel to.

As an alternative, have you tried the old squash ball under the pedal trick, as something in between? I've never raced with either mod, so I have no idea if they're comparable. The squash ball might be less force for your knee.

Yeah you need to look after them knees bro!
Have you tried this type of seating position?
This is me from my Asian-happy-style-drift-sensation SIM days..

Don't let it get out of control Mr Threepwood. You kinda need your knees IRL for a very long time.

There are plenty of controller options. Many paraplegics SIM race. I'm sure there are even G27 mods.
Title: Re: G25/27 GTEYE spring mod
Post by: Guybrush Threepwood on September 13, 2014, 10:05:44 AM
I don't think the seating position is going to change much as it is just the pushing pressure that causes the issue.  I have tried lowering and raising the seat and adjusting everything to sit more vertical or more horizontal (as much as you can in an office chair and desk) but hasn't helped.

I might try Wally's idea of a rubber ball.  I don't so much need anything stiff, just something that reduces the linearity of the brake pressure as it is depressed with as little resistance as possible.

I think it's only been an issue because of the ridiculously long sessions I've spent with AC.  I blame Dick and Marty and the Superman Jump for making me have so much fun fluffing around for hours on end.

Hope you can get better, Guy!

I used to use a set of A1's it has/had a dual spring in the brake, the stronger one kicked in about halfway down.  It has helped heaps finding the braking point.  With a normal spring one -and  fanatec is the same - indeed it's extremely hard to find the right point.

Little update to this.  Ricmotech now has a V2 upgrade which includes a different spring, rubber damper and electronic chip which supposedly give the pedal more travel/feel.  It was only $19 plus delivery, I have ordered it and will update once it arrives.
