cs2000 Posted August 9, 2018 Share Posted August 9, 2018 (edited) Hi all, Our Z's have Traction control as standard, this can be temporarily disabled by pressing the TCS button under the steering wheel, but it comes back on again next time you start the car. They also have what Nissan call Vehicle Dynamic Control. The VDC system controls the brakes to help prevent wheels from slipping. Whilst for road use this is all well and good, it means for things like track days or drift events, or even just some "spirited driving" that if you're really pushing the limits, the car can apply brakes on individual wheels to correct what it perceives to be an upcoming spin or loss of traction. This is not what you want if you're hooning around and wanting to have some fun. Sadly this cannot be disabled with the button under the steering wheel. Various methods exist for doing this such as pulling fuses, but they're all a but lacking in my opinion, they all disable your brake lights and also some disable your ABS which you don’t want, so i've designed this. This is a custom PCB and circuit which automatically disables BOTH the TCS and VDC features on the car at the simple press of a button but leaves your ABS system alone. The clever part is it remembers if you disabled them and will automatically disable them for you next time you start the car. Great if you're doing a track day and have a few sessions booked! It doesn't trigger any check engine lights and doesn't interfere with any other features on the car. As a bonus, the 370z will still start in key-less mode which also doesn't work if you just pull the fuse like other guides will tell you to do. How Does It Work? Start up the car and you will see the LED button light up. Notice your TC and Slip lights go out on the dashboard as normal after a few seconds. Briefly press and release the button (no need to hold it, just a quick press), a relay will click and the button's LED will turn off. You will now have the TCS and Slip lights illuminated on your dashboard, meaning the Traction Control and Vehicle Dynamic Control stability aids are fully disabled. If you now turn the car off, wait a second and turn it back on again you’ll notice the relay clicks again and automatically disables the stability features for you! To re-enable them simply press and release the button again and the button LED will once again illuminate. Now turn the ignition off and on again and the TC and Slip lights will turn off on your dash. Traction and Vehicle Dynamic Control are now re-enabled just like normal. How Do I Know What's Going On? If the button is illuminated AND you have NO TSC/Slip lights on your dashboard, then the TCS & VDC systems are enabled (Like standard). If the button is not illuminated you DO have TSC/Slip lights on your dashboard, then the TCS & VDC systems are disabled. If the button is illuminated but you STILL have TSC/Slip lights on your dashboard, then the TCS & VDC systems have been previously disabled and you have pushed the button to enable them again, you need to re-start the car to enable them and get back to Standard mode. Theirs nothing else like this out there, definitely worth having if you like to drive hard or track your Z. As mentioned, it leaves the factory ABS system functional so you get the best of both worlds, ABS isn’t something you retain when you just pull the fuse. Custom Button & LED Colours As for the button, you can mount it wherever you want, theirs plenty of slack on the wires for you to do this. The decision is left to you. The supplied button is a solid metal silver switch with a red indicator LED. However! If the button isn't to your taste, you can easily replace it with your own button and LED. Full detail on this is included in the installation guide. I have a full colour guide written for the 350z and Keyser has helped write the 370z one, you need no special tools, literally a screwdriver, some pliers, a bit of insulation tape, a drill (for the button hole) and about 30 mins of time.
