Thank god there's a page 2 now. iPhone was gettin overloaded!
Looks like some great work!

The engine option we're referring to is the VK56DE. We will be looking into the VK56VD engine swap as well.

We'll offer them in three different forms: Turbocharged, Positive Displacement Supercharged, and Naturally Aspirated with Individual Throttle Bodies.

Well now if we are talking about some V8 lovin' then I might just have to take back the part about me buying the 4.2L and seeing what one of these bad boys will run me.....turbo charged of course.

Sam, is the VDC turned on/off in the video?

The VDC was left on. Our Traction Control system reacts so much faster than the stock VDC, that the ECU doesn't have time to even think about closing the throttles down on you before traction is restored. You can leave the VDC on or off depending on how you want the car to drive. For example, you can setup our traction control to allow a little more sideways action before kicking in. In that case, you would want the VDC off so you can hang the tail out more. In cases where you want minimal wheel spin, you can leave the VDC on and have the traction control system maintain maximum grip for you.

Great. Is the racelogic traction control kit on your website car specific to the 370z? It looks like a plug and play item but wanted to make sure no "tuning" is required by GTM as I plan to get a TT kit and racelogic TC and have a local installer do the work.

Yes, it is a specific plug and play harness that is supplied with the traction control unit. Also, the head unit itself is setup by us so that you don't need to worry about setting up all the various trigger settings and I/O ports. That is why it is a true plug and play system: you don't need to fiddle with it and it works straight out of the box.

Sounds great. I have some mechanical knowledge, would I be able to install this myself or is a shop recommended? I read through the racelogic install manual and I am assuming we can plug directly into the ABS module without cutting and splicing wires?

Thanks

Our plug and play system is just that: no splicing required. It is so simple, we timed our technician and it literally took him 78 seconds to plug it all in and drive away. The only reason you would need a shop to install the system is if you want a super clean install of the head unit that you would be unable to do yourself. But for all practical purposes, getting the traction control installed and working only takes a minute or two to accomplish.

Also, every system gets installed in our test car, flashed, tuned, tested and dialed in before it ships. That way, there is nothing the end user has to do except install it and go.

Speaking of the Race Logic system...

elperuano · 03-21-2013, 05:03 PM

What's the difference between this and the factory vdc? I read it kicks on sooner? Is that it?

The difference in performance will blow your mind.

Basically the factory VDC is a nasty, intrusive POS that gets in the way of having fun and if you turn it off, then you could end up wrapping your car around a tree if you're not careful. The factory VDC closes the throttles and murders the power for a bit before giving it back to you. On corner exit, this stability control strategy is a total killjoy and really takes the fun out of the car.

The Racelogic, on the other hand, is barely perceptible when it is doing its thing. Basically, it interrupts the firing of a single fuel injector for a single cylinder so that it takes a gulp of fresh air instead of a fuel/air mixture to limit the power. It does this on a rotating schedule as needed so that each cylinder gets a fresh air charge in turn. As you can imagine, this happens extremely quickly. The traction control monitors the wheel speed every thousandth of a second and at the first hint of traction loss cuts just enough power to maintain traction so quickly that the factory ecu doesn't even realize you were about to lose the tail of the car. In fact, you probably won't notice either. All you'll feel is hard acceleration that maximizes the grip your tires and suspension can hold.
