Z-tech traction control module + brake boost + burnout
 

So I'm sure plenty of people have wired this all individually but I stumbled across a thread over here https://www.350z-uk.com/topic/121590...e-with-memory/

That thread eventually spun out into this site https://www.cs2000-z-tech.co.uk/coll...disable-module

Basically it looks like a momentary switch => microcontroller (assume for memory feature?) => 2 relays one for yaw and one for brake switch (i think)

Anyone ever heard of this? I'm thinking I might order one.

No need for it. You can do it all with ECUTEK for the most part. If you want a motorsport grade unit, Motec is the way to go. Not cheap though.

I wasn't aware you could turn TC entirely off via ecutek. Or that you can do burnouts/brake boost. I don't see it mentioned specifically on the site but that's interesting. Thanks

one day on the motec, ecutek looks like it has configurable TC which is nice actually didn't realize that

So If I'm looking to disable TC entirely for track days I just need ECUTEK? or ecutek + yaw sensor power switch?

Ecutek does most of what you need. But you need the yaw switch, too, if you want everything off.

You need to get on the track first before you start doing all these mods for the track.

Have already been once! But I'm preparing for a busy 2021 season. Stuff takes so long to order and install these days have to plan ahead.

You’re doing it all backwards. Put the money in seat time. Gradually mod the car the faster you get.

I think he must be kin to JChammond. LOL

Both! What's the point of reading every thread in the track section if I can pre-empt some of my issues using the knowledge and experience of others.

All that is subjective. One track day can’t justify experience others have had. You just need pads, brake fluid, oil and diff cooler and maybe a surge tank. Once you start out running your set up change things accordingly. What a professional driver told me, you change to many things at once, it’s harder to tell what isn’t working properly and diagnose the issue. You will have a huge reality check when a 140hp miata runs circles around you.

Yeah, it's all subjective. You have to tune the car to the way you drive, and you can only know what to tune when you know the car through time.

I've had mine for 8 years now, and I made some big changes this year to it. First outing at the track, I went off (full 360'd it, it was sweet) because I just wasn't expecting some of the results of those changes. It's always best to learn, and make incremental changes.

Good to keep other experiences in the back of your head so you know what to do if your own experience matches up, but ultimately you won't know what to look for if you don't baseline it. And keep in mind your baseline that you establish can change even day to day - temperatures, track conditions, what you ate that day, your mood, etc. An installed part can't fix that.

yeah i agree for the most part. I know though there are going to be things I will do regardless. Like yaw disable. I will do it if only because I want to be able to experience it.
Not everything is about track times as well. I like modding and adding gadgets to my cars/house/etc because I find the process fun. Not everything is purely driven by practicality. That would be incredibly boring.

I know I'm going to get an ecutek tune so probably a hardwire yaw switch + that will be fine and I will skip this thing. I was more hoping if anyone had used it before, i'm curious why someone went through the trouble of making it vs using ecutek and a switch on power for the yaw sensor.

I have a need to know about every option. And to extensively research and gain knowledge about everything to do with the stuff I try out. So that means tracking down information on every esoteric part and mod, and asking questions and shoving as much knowledge into my head about this platform as is humanly possible. Sure maybe lots of that information doesn't apply to me, but I still have the desire to acquire it and understand it as much as I am capable at any given time.

It was made for a 350Z. There are better options for the 370Z. That's why you don't see any info about it on this forum.

The stuff on this forum is tried and true for the most part. So if you don't see it here, chances are there are better options or it's been found to be more hassle than it's worth and you'll have to be the guinea pig.

Baseline is going with a 100% bone stock Z and only being able to get in a handful of laps before the brakes go away or oil temps go sky high and shuts the car down.

Seethru. What you should do. Do a trackday or 2 with a bone stock car. With the VDC on. On used up tires. Push the hard as you can. Try to get the rear to step out. Feel what it's like to drive an unrulily car. It's call experience. Then slowly make your changes as you get faster with more track time. If you throw everything at the car all at once. You will have a big hole in your learning. If you make all the changes at once. There is a good chance that you will not get any faster. I've seen guys do one trackday. The next time I see them. They went out a bought a set of JRZ 4 way coil-overs. :yum: Have no idea on how to set them up. And spend the rest of the season trying to figure out why they never got out of the beginner group.

:iagree: It's like when bad drivers with no track experience go out and buy a Lambo or Porsche 911S to learn how to drive fast.

ok guys just gonna spend 5 years with traction control on and then i'll come back to this thread

Do want you want. It's your money. We are just trying to tell things from our experience. A lot of the guys who chimed in have years of track experience. My track time goes all the way back to the mid 70's. I've seen guys like you jump in with both feet and then bail out before the season was over. Asked them why. It started out as fun, but then realizes that they was in over their heads in learning car set up. Couldn't figure why they wasn't getting faster. And no longer enjoyed it. Want to know what is an ego destroyer is. Passing a Miata coming out of a turn. Then only to have it pass you on the brakes going into the next turn. And if there is a series of turns. He lost you. You won't even see his tail lights.

I think all of us here understand that the basic longevity/safety mods don't really affect how the car drives. Oil cooler, brake fluid, brake pads.

It's different than taking a stock car, before you've driven it, and removing the electronic aids, adding a bunch of camber, making it stiffer, and throwing power at it hoping it makes you a faster driver.

Ok

I usually do mods because they interest me. Since I'm waiting till I track it a bit more before I swap wheels/suspension and other things that permanently change handling.
I need to find small things to do to change stuff.
Cool thing about something like this is it's just a switch and I can turn it off.
So I can directly compare the experience with TC off, Tc on, yaw off.
Which is helpful so I can understand what each setting is doing. And it alleviates my boredom.

I think that Z-tech module with easy on/off button looks pretty simple!

I still rarely shut mine off, I've learned to drive fast with it. I think I have put down some fairly decent lap times on street tires. If anything it keeps me more comfortable to drive closer to the limit more often.

I agree. Ssfirehawk has a custom Tc set up and it’s magic. I was highly impressed with it on the track last spring.

custom TC is the reason I'm so interested in motec. After watching Sasha Anis talk about it on the speed academy channel

I had my 370z tuned & did not feel any difference. I put a sprint booster on my car & I cant believe the difference it made the power I felt. I spent thousands of dollars to gain more power. What a wast of money. All I needed was a sprint booster. I already know it dose not give you any more HP then the car already has BUT it give you the power the car already has instantly. There is just one problem I have now. After two years driving with the sprint booster it stopped working & no one seems to know what the problem is & Im out of money to find out plus I dont even know where to take the car to find out why it dose not work any more even if I had the money. I have 3 sprint boosters so I know it not the sprint booster that is not working.

:rolleyes:

Any competent tuner is capable of adjusting your vehicle throttle input so that it is identical to a sprint booster module. All sprint booster does is increase the voltage to trick the computer into thinking the gas pedal is pushed down further than it actually is. A tuner can do the exact same thing. The problem with doing it this way is the reduction of precision of the throttle input. What's the point of having a full pedal throw when you program WOT into the first 1/2 of the pedal travel. Which is why you don't see any tuners doing this.

Obviously your tuner didn't even touch the throttle response because you definitely would have noticed a difference.

On my first track day I beat far more experienced drivers and it had nothing to do with skill and was only because I was in a faster car with better handling. A car which I had already modified to be faster. I even got within a second the time a guy with 2 years experience on the same course got with his stock 370.

A lot of the advice here that you can't go faster without seat time is just wrong.

Who said that?

I don't think that's what anyone is trying to say. More that the stock car is plenty capable for a novice driver. And it is a better value to spend money on seat time with an instructor than on modifications. Seat time is just more valuable in general - you can take it with you to another car. And for a novice, most people would recommend the seat time before going hog wild on mods with limited initial return value.

Put that experienced driver in your car and see how much faster he is. And how fast would you be in his stock car? I think that data might give you a reasonable indication of the value of mods vs seat time.

What track, and what was your time?

Just wait until you get on the track with some spec Miata's practicing. You might be able to pass them on the straights. They will run your azz over in the corners.

Without a doubt the experienced driver would have got a much faster time in my car, but that's my point. It was a better car and the better car allowed me to get a better time, regardless of skill.

With seat time you are limited by scheduled events and sometimes there are so many entrants that you hardly get many laps in.

Just adding stiffer springs, for instance, makes the car handle so much better over stock sloppy suspension

It was an amateur event in a small town.

I don't need to wait. I got absolutely cleaned up by a stock 370z with only adjustable arms in the hands of a grandpa driver on street tyres in a professional televised event. He beat me by 10 seconds.

I think you are missing the point. Yes a more well balanced car will result in better lap times. It is why you see fast lap times from low skilled drivers in late model cars or track cars that have been properly setup. Those cars mask the driver's true abilities. You went faster because of your confidence along with your new setup. Good for you! That said, you are still limited by your time and understanding of proper driving. Your new found confidence can also lead to tragedy (I really hope not) as many drivers that experience what you have end up in a scenario where they run out of talent because they think they are better than they are. The thing you have to keep in mind is the faster you go the greater the consequences when things go bad. As Clint Eastwood famously said, "A man has to know his limitations!" :tiphat:

Well said. :tup:
