Traction control doesn't build boost, that's anti-lag. I think you overestimate the ability of a retrofitted traction control system into an older car. Either that or I am underestimating it. The Z32 is a 2WD car with a mechanical LSD. The only thing a traction control system can do in a car like ours is cut fuel when wheel spin is detected - i.e, stall the engine momentarily. There will be no fine distribution of torque between the rear wheels - your acceleration will simply cease. Then start again a few tenths of a second later. Since our brakes are entirely hydraulic (bar APS input) there will also be no four-way separate brake application applied by this system. Hendo's Soarer has a similarly rudimental traction control system standard. Mechanical diff, and all that happens when you spin the wheels is the engine cuts. It feels like a misfire, not traction control. I assume it'll detect wheel spin through the ABS sensors? I wonder as well how well they'd do the job, being repurposed 20+ year old sensors designed to assist braking. This is my understanding of how it will work, though I may be mistaken. It will be shit. Stop banking on an after market gizmo for your safety and just learn to control your car. It is not beyond you.
The racelogic has launch control and traction control features -so yeah will do both. Loss of traction is detected via the wheel speed sensors and yes engine is cut via cutting fuel to cylinders. They get some really solid reviews, I think you're under estimating it. But I also think it's something of a gimmick. Oh and Z32 has viscous LSD, not mechanical
oh shoosh you I meant mechanical as opposed to electric. I will be very, very, very surprised if a Z32 will launch faster with a retrofitted traction control system such as this...
I'm aware that traction control doesn't do that, but this unit has an anti-lag built into it. Have you researched this product as of yet? The majority of what you've said is pretty spot on man, but I've read a substantial amount of good reviews on this product. I'm not banking on this product to be a lifesaver, that isn't the purpose of me buying such a system. I'm not questioning my driving ability by wanting to purchase this, I have no doubt that ill drive to the conditions once its on the road. But if you had a way of going quicker and safer, you'd want to look into it wouldn't you?
I recently PM'd a member here and asked his opinion on it: "The system as a whole is pretty good. Installation was a bit fiddly as you need to intercept injector wiring down at the ecu then you need to tap into abs signals as well. Not hard just got to make you you get the wires correct. Setup software wise is easy. I found that its great for wet weather use. At the track though, I find it quite annoying as it made the car a bit inpreditable but that might be that I never spent the time fine tuning software. Launch control works well and lots of fun to use. Overall expensive bit of kit for what it does."
Taken from google; An all too familiar scenario, the rear end starts to geta little unstuck, the driver doesn't catch it in time, and that's it, 3500+lbs. of metal, plastic, and leather heading towards the scenery. Nissanhas put a nice powerful road car in the hands of the general public, thelikes of SGP, JWT, NISMO etc. have given the general public the abilityto make an already quick car even quicker, unfortunately the skill requiredto back up that power and handling is not there, and even if the skillwas there, often things just happen on the road people have no controlover. "You're only as good of a driver as you thought you were until therear end gets away from you" What is the Racelogic Traction Control? A way of controlling excesspower (or even just "normal" power in slippery conditions, IE ice, snow),without detracting from performance, or the driving experience (in factI firmly believe that TCS adds to the driver experience). Conventionaldriving skill in a rear wheel drive car in over steer situations is tofeather the throttle (lift-press-lift-press) as the rear end goes intoover steer. Lifting off the throttle completely transfers the vehiclesweight onto the front wheels unbalancing the car, or giving too much throttledecreases grip as the wheels spin even more, either method results in atrip to the scenery (at best, at worst potentially a lost life). The TCSsystem feathers the throttle automatically, without closing the throttle(in a turbo car causing the engine to come off boost), or using the brakingsystem. It interfaces with the ABS system to "read" the wheel speeds (andcalculate the wheel slip on all 4 corners), and interfaces with the ECUharness to cut engine power by cutting fuel. The two additional modules I purchased were the launch control and adjustableslip controls. I would whole heartedly recommend the adjustable slip module, whichgives you the "adjustable fun dial" as I call it. Basically you can selectthe desired amount of wheel spin on the dial 0%-5%-10%-15%-20%-OFF.. at0% the rear end will not go into oversteer, 10% and you've got a bit ofoversteer going on, 20% is for serious showboating!. Launch control allows you to do perfect launches whenever you want -it lets you build boost on the line, drop the clutch, maintain wheel spinand generate max acceleration off the line (perfect for those 60ft times!). Whilst stationary you select the wet or dry launch (dry has a hard cutlimit vs the wet soft cut limit, IE the dry will build more boost), pressthe launch control button, floor the throttle - the engine "bounces" offa secondary rev limiter controlled by the Racelogic system - in fact itsounds like a Rally Car on the start line. Once max boost is generated(around 5-7psi in Stg 3 car @ 5500rpm limiter), you let go of the clutch.The system modulates engine power to control wheel spin - gradually feedingin engine power until full power is unleashed and then it's time for 2ndgear! The launch is absolutely incredible, but a side effect is you haveto have a good clutch, otherwise this will ruin the clutch quickly. Speed shift allows you to leave the gas pedal on the floor while makingshifts. When the clutch is pushed in, a new rev limit is imposed on theengine so the engine won't over-rev when the drivetrain is disengaged fromit. Coupled with the launch control, it can make a standard perform likean automatic for acceleration. I won't go into the technical details of how it works (go to www.racelogic.co.uk)other than answering four of the most common questions/comments: 1. If it cuts fuel, doesn't that mean it will detonate? An emphaticNO, what it does is cut enough fuel to create a complete misfire on oneinjector pulse, cycling around all the cylinders. Enough fuel is cut outso a complete combustion won't occur, but not too much fuel so that thecylinder won't dry out. 2. I've been in production cars with Traction Control, they were moreof a detriment, how come this one is so different? The Racelogic systemis race derived, and adjusted to each application. It has an extremelyquick sample rate, and is fully adjustable in how much fuel it cuts out,which revolutions the fuel is cut, which cylinders etc etc all settingsare accessible via a PC connection. The system only cuts just enough powerto limit or eliminate wheel spin, but not so much to degrade performance.Many production systems are too slow at reacting and cause the engine todrop power dramatically when they kick in. 3. But I'm a good driver, I don't need it! No human can modulate enginepower without using the throttle, so even if you were Michael Schumacher,you still wouldn't be able to control power delivery without closing thethrottle, and doing it 10 times / sec. There is a reason why lots of racerschoose to install race spec traction control systems, as it offers theability to bury the throttle and get the maximum amount of power deliverywithout having to modulate the throttle as the rear end starts to get unstuck. 4. So, what's it like? Full throttle, 2nd gear, in a stage 3 car onsuper grippy 17" tires partway through a corner, in the wet, and not havingthe rear end go into oversteer sets the stage for how well this systemworks. I simply could not believe the night and day difference in characterof my TTZ in both wet and dry conditions. In the wet it changes the carfrom being on the thin line, to completely in control, in the dry it allowsme to get on the throttle earlier, and hold the throttle down in a corner.You get to a point where you jump on the throttle immediately after turnin, and only lift if you're understeering. It's an eerie sensation, especiallyif you're "used" to driving a rear wheel drive car, but after a while youget totally comfortable with the system. I asked Racelogic "Would I knowwhen it starts cutting power?" "You will".. and you do, the engine soundslike it's missing, but not badly. Hard to describe, but it cuts in andcreates a repeated misfire that sounds very "race-car-ish". Strongly recommended for anyone, be it Drag Racers, Road Racers or Sundaydrivers.

Anti I think you're getting confused with stability control. All traction control ever does is cut engine power when it detects slippage. Although some newer cars with an open diff can brake the spinning wheel to place load on it (which isn't really necessary since we have an lsd anyway). Stability control on the other hand can brake wheels independently to bring the car around and blah blah blah. Yes launch control is cool and can be useful. But Jamie thinks he can slide an auto na in the dry so maybe this will help keep him from going in to a tree backwards on a rainy night.
Another option for launch control for you; if you went with vipec management (and probably others) you can tailor separate boost "maps" for each gear. Limiting boost in 1st would let you get off the line in your powerband without going sideways... E-boost can control boost "delivery" according to rpm but I don't think it recognises different gears.
I think youre mixing up traction control and stability control anti. As far as im aware this particular tc kit is the best value tc kit on the market. Hell there is heaps of more expensive ones, but the difference is marginal. For less than $1000 you can have a tc unit the equivalent of a very expensive modern day sports car. I definitely want one down the track, there are days where i really cbf sliding all over a wet road by accident.
Rob, if you watch the eboost tutorial the bloke does mention you can have gear specific ramp up. No idea how it works, though. Jamie, if you want antilag/launch control, fine. I personally think unless you're going to make a massive hobby out of drag racing (ie down there at least once a month), it's pointless, but it's your car. You can launch and get good times without antilag and launch control and once you do, you'll feel much more accomplished than if you got there with the help of a little box... As far as talking about the safety of the traction control, piss that right off and just learn to drive the car. Your right foot controls how fast you go and yeah, sometimes things do go wrong, but they aren't THAT dangerous. It doesn't feel right to me to add safety systems to a car that is really a raw sports car. New cars these days have no soul, no skill required to drive them, the gap between a good driver and an average one is getting closer and closer because the cars drive themselves, fine for a regular car but pathetic for a sports car, I think. Anyone can drive a 350+ kw car with traction and stability control, it takes some brain power and skill to drive a car with power when the only thing stopping it from losing control is the driver. Seriously man, learn to drive a manual properly BEFORE you get into this thing. The main thing is having a good understanding of how to control a manual car, which includes throttle control a lot more than an automatic does and it'll be a necessary skill when driving a quick car. Get your tuner to set 3 settings on your boost controller if you can. Make the lowest one gate pressure and get used to it. Yes your car is going to be fast, but if you use your brain it won't end up in a wall or wrapped around a tree. Just my opinion.
This is what I'm talking about. Wtf? If you're driving in the wet, drive to the conditions and you won't slide all over the road by accident. Traction control isn't going to stop you aquaplaning on the highway, it only cuts power under throttle.
Not quite sure what your saying? I dont know if you are agreeing or berating my happy go luck driving. The point i was trying to make was that i want launch control, and having tc is a bonus safety feature. Im building a tt and im hoping to get in the 500-600hp range, personally having adjustable traction control sounds like a fantastic idea, especially when still learning my new engine. Better than setting my boost controller to "flacid" anyway. I dont wanna jump in my car in the middle of a rainy night to get something from the chemist or whatever and accidently wrap myself around a tree because im not used to it.
No, he's saying don't drive like a dick and you'll be fine. If you're aiming for that power range, you're gonna be needing to run some decent sized turbos (2871's maybe...) so you will have no power until ~4000rpm. Drive to suit the conditions If you crash, you have no one to blame but yourself.
Pfft me drive like a dick? Never In all seriousness tho, i have to take off from lights in second in my na, otherwise when my wheels touch the white line they chirp. I generally do drive to the conditions, but there are times you can mess up. If im getting a launch controller i see no harm in using the tc as well.
Shit dude, thats really impressive that your NA will spin first on a normal launch... Mine (also the highest powered NA on the forum) wont do that without me trying. You must either drive like a complete wanker or have shitty, worn out tyres. Either way, you're endangering other peoples lives. Anyway, Sorry Jamie for straying off topic.
No worries man, just starting to shit me that people are telling me what to do with my car when I first drive it. Sick of people judging me because I've lost my license twice in a Auto NA, sick of people judging my driving ability when the majority have never been in a car with me whilst driving, sick of people thinking I'm going to hop into a 400kw car and thrash the shit out of it straight away. Everyone that I speak to about this car knows very well that I'm going to be driving it at waste gate pressure for a decent amount of time. Whilst I'm young and love the thrill of a fast car, I'm not the dick that everyone is making me out to be. You can lose your license in any car... Everyone's adding their 2c to enlarge their e-penis, hardly anybody speaks to me about this privately.
