GTM Racelogic Traction control Review
 

There as been a lot of discussion about traction on the forums with boosted Z's.I get pm's all the time about the 3.3 final drive and then you have the tire discussion thread.So I decided to make a quick little video of my car with the GTM Racelogic traction control. I installed the traction control system in January and I have not had the time to really test it yet.


Here is my set up

Car is lower on swift springs
3.3 final drive
305/30/19 RE-11 in there Rear


Racelogic Key features
1.The ability adjust 1% increments from 0%-25% allowing the driver to dial in the perfect setting for there car. Now there are many factor's that contribute to this tire's/suspension weather condition's.This can be done on the fly just by turning the knob

2. 2 Step launch control allows you to build boost of the line and adjust how much slippage you want.



Low boost 600whp 545tq
45 Degrees outside

I decided to mount the unit next to the steering wheel for easy access to the unit for using the launch control and setting the slippage percentage. I have seen pictures of the unit mounted in the glove box, for me that would be a pain because every time you start the car the system reverts back to the wet setting.

In the video I am doing a 5500 rpm launch with the 2 step that comes with the system. Once it get's a little warmer I will take some more footage the Racelogic is a great system.

Did you go with the no lift shift by chance? I am excited to try mine out. No blowing off boost between shifts sounds win win.

In for more details.

In for more info too.

Camera goes out of focus just as you are launching! Grrrr.

Wow that's really nice! So you can just hold down on the pedal to launch?

How is it coming out of a corner?

You set the rev limiter you want and it will hold the car at the RPM until the clutch is released, then once released it will control your wheel slip to the desired percentage.

Mr. Squeeze, did you by any chance have a 2step with uprev before going with the Racelogic system? Just wondering if there is a massive difference or if you could even compare the two. I know the uprev isn't a true 2 step and I know the racelogic system has a lot more going on just curious is all.

I got the 2 step with the Racelogic system Uprev doesn't have launch control.
If your talking about the valet map that Uprev that Uprev has there a big difference.

I do not have the no lift feature right now and according to the manual you have to install a clutch switch for it to work. The switch has to be install on the clutch pedal where the contact makes or breaks when the clutch is depressed. This is something I am looking to do full throttle shift's and holding boost would make the car faster.

I haven't tested it coming out of a corner yet because it's still not warm enough outside. As it gets warmer I will be doing more testing with the system.

I posted a thread on it a while ago with a video from Uprev themselves. Uprev can two step...sort of. Like I said I know its completely different and im sure its not even comparable was just wondering if you played with it at all.

It's just a map change that shifts fuel cut lower.. it's not a two step, at all.

It will just surge up to the limit, then slowly drop back down and then surge back up, over and over with about 2-3 seconds between surges. AND you have to be holding your buttons on the steering wheel in just the right sequence in order to trigger the map change at exactly the right moment. It's totally useless.

I would like to see this video if you don't mind posting a link. To me it sounds like your talking about the valet where you set a map at a certain rpm floor it then pick your performance map hold and let got.

Put it this way this in the video that I just posted I dropped the clutch at 5500 rpm's and floored it building about 5-6 pounds of boost. This was done on cold tires in 45 degree weather if I try this without the Racelogic I get massive wheel hop. Look at my low boost graph and how much torque I make on low boost.


14 PSI

Yes it is useless I use this for when I park at the valet. I have tried this at the track in my 350z and it flat out sucked.

Okay I didn't know what you meant until you put it that way. We are talking about the same thing with uprev :roflpuke2::roflpuke2:

But seriously, holy torque batman. So much so early. It really is impressive how well it puts down all of that power.

The clutch switch is actually in the harness that you got, you just have to add a tap to the line. No need to add another clutch switch as the stock one will work just fine. I wired mine in last night.

Im not sure if it is as simple with the GTM setup you have. I do know that to add the no lift shift you have to tap into each of your abs sensors, which is something you do not have to do with GTMs setup. I would give Sam a call and see if it is possible to add to your existing system. If so I would be more than happy to help you out.

Thanks for the info I will give Sam a call and ask him let me know how you like the feature.

Dunno yet, we are still sitting under a bunch of snow. Hope to try it out in a few weeks if the weather smartens up. I am jealous of your video, very jealous. Mind you the snow would definitively make the traction control work overtime. haha

Repped for great write up thanks man.

Thanks for posting. I'm not sure what to do first... Engine build, or this... ;)

Wait till I get mine on the road ill upload some videos, its gonna be suhhhweeeet. haha

I know, I know... I saw your thread and I'm already making plans to move my heated seat switches to inside the console just to make room to mount the Racelogic. :bowrofl:

Now there is an idea, if you do decide to do that ill pay you to fab up a second for mine :p I might do it myself if I decide that where I want to put it is just not going to work.

That really is impressive and great writeup too! Guessing this is pretty much an FI only mod?

No. Would be great on an NA car too. I am sure you know how annoying and obtrusive the stock system is.

hi
thats how i installed the race logic in my car

This is true

Now can you do this same mod so that you can get launch control on the 7 AT. I have one and canot figure out how to make the launch contol work off the line.

I don't think this feature work's on a auto car.



I have played around with the system in the rain 25 degree weather and it ,and it was working hard. I would't have the guts to try it in the snow it would work overtime for sure though.

Looks nice, but I feel like if I had a passenger (aka the girlfriend) and she had her bags between her feet and whatnot they would hook it and tear it off. I like the CF tho!

So is it the general consensus that it doesn't work or doesn't work very well on AT cars? I hope GTM can chime in on this one.

I dont see why it wouldn't work, there is nothing different about the auto once your moving. As far as launch control goes all you have to do is tap into the brake switch instead of the clutch switch. We all know that you do a brake stand to launch, so in this way the brake acts much the same way as the clutch in the standard when starting off.

I did a bit of googling ( yes Kenchan, googling) and did not find a perfect example of this however. I would put money on the fact that it would work however.

Can this system be installed only by GTM or can it be installed by others?

Its not GTM's system, they are selling you the Racelogic system with their branding on it. I am installing mine on my own from scratch, it is not all that involved, if you can install a stereo you can install this.

Actually I lied, your launch control has nothing to do with a clutch switch. Once it is turned on it shuts itself off when the wheel speed between the back and front tires fall within a certain amount, this means it would work just fine on an automatic. With the no lift shift you have to tap one extra wire at the ECM.

From the manual.

"The system uses a secondary rev limit that removes itself automatically when the rear wheels are within a set percentage slip of the front wheels"

The way we offer the system with our plug and play harness will allow anyone to install the system it in less then 2 mints . the system comes from us flashed, programed and tested. or you can just buy the system without the PNP harness and do the wiring you self.

Here is a link to our instructions

The launch control feature will work on an M/T or A/T car. This functionality does not require any switches to activate it, it is a simple user define setting in the controller.


Sam

Mr.Squeeze

Thank you for sharing. Now are you ready for some big things :D

Sam

That does look super easy. So when people mention plugging into the clutch switch for launch control that is already taken care of with this install?

I goofed, there is no clutch switch for launch control. There is a clutch switch for no lift shifts.
