Since some of the cars have ABS I was wondering if anybody has put Trac Control on an FC. Could it be done?

 

havent heard of it being done, but it wouldnt be hard

 

The DTSS is a sort of "stability control" in its own way from the factory (when it still worked), by changing toe to maximize grip under various conditions. It just wasn't electronically controlled.

If you wanted a modern type of traction control you would need a standalone EMS that can support it, with wheelspin sensors and timing retard settings.

 

can you give more input?

 

See above. High end EMS like Motecs and such can support it as long as you have wheel speed sensors (4-channel ABS cars would already). Its not hard, but you are gonna pay alot for the electronics to do it.

 

You do NOT need a super expensive EMS for traction control.

All you need is this:


You don't even need ABS. Pictured above is my RaceLogic traction control system with wheel speed sensors.

I know the RaceLogic system can tap into the ABS system of an FD to get wheel speeds from the sensors. I am not sure if it can work with the FCs ancient shitty ABS. My car doesn't have ABS so I had to get the wheel speed sensors.

What does the installation of wheel speed sensors consist of?

Is it difficult to retro-fit them onto FCs?

 

Wheel spin control = modulation of right foot.
Launch control = modulation of clutch and right foot.
Get Bigger/stickier tires :P

You could run a megasquirt for half the cost.

If you don't have ABS wheel speed sensors, the Racelogic sensors cost another $500.

The factory ABS sensors are more then accurate enough for the Racelogic system. The Racelogic sensors are usually setup for bolt detection (lug studs or axle bolts).

The Racelogic traction control/ launch control system is fantastic, but is priced in entry-level standalone territory. The systems start at around $1000.

 

So $1600 for a non-abs equiped car? Very interesting. Do you have any info on the installation of the wheel sensors?

 

I never even realized it was 'that simple' to add traction control. I learned something today!

 

Traction control is so stupid. Why would you want it? Why wouldn't you wanna drive a car like it was meant to be driven.

 

this is the future of fast cars. screw that BS awd extra weight crap. RWD with traction slip when the tires start to break loose.

Hell, essentially the R35 is a rwd car with FWD being secondary when it looses traction in the rear.

 

Traction control is a great advantage on daily driving. I turn it off in my 8 doing drag, or dyno, but it is on at all other times.

Last year at the Mazda Zoom Zoom event, I was about 1.2 seconds quicker in the Mazdaspeed 6 with the traction control on, than with it off; on the road course.

There is a reason that the F1 cars this year are wrecking and having higher course times, than last year... because last year they had traction control... this year they don't.

 

+1 for FC with traction control

 

Traction control and stability control. Not quite the same.

 

Daily driving yes, thats why so many new Mazdas have it. I've driven a few RX8s and I say it sucks horrible with the traction control on...I'd rather dump the clutch and 9 grand and spin the living **** outta those dunlops....then again you can still spin um pretty good with the traction on..not as good as off though.

I don't know, I race short track personally so I don't like having ABS, or TCS or STM. I'd rather have the car with no assists, thats a true test of driving skill.

 

thats what i was thinking....

 

with all the cars i've driven i haven't driven with ABS or TCS or STM. i can see the benfits and cons... but i'd agree with this guy above, how would you know the limits of the FC with pushing to them? i was born into drving without assists. I believe it trains your judgement in drving better , you feel more of the car.
to me it you feel more of the rawness of the car thru out the track. i learned alot of this in gran turismo 3 & 4 and Forza 1 & 2. about these systems. although i don't have any reality track exp with them but simulated exp yeah.
personally i'll be the slowest guy on there if i ever when so i can learn the braking lines and enter and exit speeds.

ABS or TCS or STM having these on will assist you in finding those limits without breaking them or undue harsh actions. spining out, fish tailing ect. to me it seems like you could catch the problem and correct it before it happens.
but all of our driving style is unique thats what i like about motorsports each guy perferrs different set up on the same car. like there more than 3 ways to cook an egg. thats just my 2 cents

 

How would you tailor this into the stock/aftermarket engine ecu? Also, since the system can reduce power in 2 ways, which is safer for a high powered rotary? By cutting a single injector pulse or a spark?

SO it can be done. I had seen a few owners of FD's talking about having it done but not the FC.


I drive new cars everyday and have seen the benifits of these added on systems.

Another one that would be nice to have is VSC(Vehicle stability control). I don't think it would be cost effective to add though.

 

It is safer to cut spark then fuel.

Stability control would be difficult to add, since it works with the ABS.

 

After reading more on this elsewhere, it seems the general consensus is more in favor of cutting fuel rather than spark. Also the manufacture has stopped advising to cut spark.

Wouldn't cutting fuel cause detonation due to rapid lean conditions? And would this be enough to do any harm to the engine?

 

Megasquirt can do traction control?


In my case - Motec M820 - I have a hal-effect speedsensensor that screws into the Type-R boxes cable. When I put the FE 6-spd in I'll have to put 2 or 4 magnets at opposing angles on the driveshaft and then a sensor mounted off of the top. That gives wheel speed. Then an extra input off of the front wheel for a second speed input. The EMS does the rest. Motecs are really nice for a SHITTON of reasons. One of the ones I like I plan on useing before I go for the whole traction control add-on., It's boost VS gear

 

Yes.
