if you do have launch or traction control. if so can any one recommend one that's work well with car 300zx tt and how is yours on your car ,after the swap from auto to man I would like launch control

I have always thought it is a bit of a con really, some of the best cars ever made offering teh best driving experience possible don't have traction control or launch control, I have always used it as an excuse to become a better driver :p

Racelogic Traction Control is probably the best and well known aftermarket traction system.

 

I had it on my old car and it was without doubt the best mod I ever done!

 

The system itself is hugely customisable for how you want it with easy to adjust software

 

You can then get an in car adjuster to tweak while driving giving variable slip rates (fun rates! :D )

 

Also available with launch control (bit gimiky IMO - tried it & didnt care much for it so didnt bother on my car) and full throttle shift option (hitting the clutch kills the revs but allows you to keep the throttle wide open for no turbo lag between shifts)

 

Anyone that has ever said TC is for people that cant drive & takes the fun out of driving has never owned a system like this! It was designed for track cars and is performance enhancing as well as giving a better dgree of safety especially in wet conditions!

 

Shame the new owner of my car clearly thought the "off" function was more fun........only for a short while however!

the race logic does look good I hear good things of the magic is does. if your running big bhp could help use all that power better and in the wet than just smoking the tyres I would think a 300zx with say 450 plus bhp would be nice to have the race logics in it

Honestly, it really does enhance the driving experience rather than hinder it like many manufacturers systems. Well worth it and have never heard. Bad word from people that actually have it fitted.

I would like it one day after the car is finished

Agreed...

the price of them tho is a little steep

Not cheap but if you want a system that actually works then it's pretty much the best you can get. Got mine years ago on a group buy and was worth every penny IMO

is it easy to fit or do you need to take it to some one who knows what there doing

It's not too bad if you are ok with electrics. Power and earth to unit. Wires run to ABS control unit to splice in for wheel speed signals. Cut all injector wires at engine ecu and solder in wires to traction unit. Run wires and fit in car adjuster control. Think that's about it IIRC

I've got the race logic system in mine and agree that it's very good

did you fit it your self and how often do you have it switched on

Fitted mine myself tho vehicle tech as a living lol! Never turned mine right off, just varied the slip depending on conditions! 20% slip with the setup I had was more than enough fun lol!!

did you have launch control with it

I didn't bother with launch. Bit of a gimmick IMO. With the slip set to max I got the best launches & times on my car when testing. Tried it on another car and wasn't really for me.

Whilst I do not have RLTC, I'd agree with Paul's statement..... If you're going to fit any kind of TC, then pay more and fit the best; or don't bother at all.....

 

Richard:cool:

I have Race Logic fitted it to mine, with on interior it still took 2 hours. I up graded to the control digital box which you can change any setting on the fly, my tt has not got big power (about 350-370bhp) but in the wet it cut's in and you don't feel anything if on full wet setting.

By turning down TC(launch control) you get more slip angle with out losing control. Regarding launch control it's not a system were you rev the engine and dump the clutch it is designed the help the drive get away better, you still need the control the clutch and feed the power in.

The flywheel stores rotating mass which is turned into forward movement from the tires but to much and you start to spin and tires start to have less grip as loss of friction, what the launch control does is limit the friction loss when you accelerate but the wheels still spin. which is all about physics of grip and accelerating ect which to much to go into.

sound great have always wanted it in past cars but the 300zx if a great car to have it in as will be driving in the wet not just dry days .so if I use the race logic how will I fit a launch control with is the type I can just hold the rpm and dump the clutch or is it case as with the race logic you just don't need it

To quote RaceLogic:

 

"Launch control is a function within the Traction Control system designed to automate standing starts to maximise the initial

acceleration. It is activated by pressing a button on the traction adjuster when the car is stationary. This will bring in a secondary

rev-limit (for example 4000 rpm).

 

The throttle can be fully depressed without over-revving the engine. The car is put into gear, the throttle floored, and then the

clutch is engaged, whilst the launch control system controls the wheelspin and revs for the perfect start.

 

On a turbo charged car, if the launch control is active, and full throttle is given for two to three seconds, the boost pressure will

build up before the clutch is released, resulting in stunning off-the-line performance."

 

 

You can add launch control to the system, by adding a button. The s/w for launch control is present, even on a system sold

without it. This thread shows you how:

With the some Race Logic TC comes with LC, but as I said before you cannot engage LC hold down your accelerate and then dump the clutch because Race Logic units was designed to use on tracks at first then became available to road cars.

1.10 Launch Control

1.10.1 General

Launch Control is a method of controlling the revs at the start. It is activated by the

launch control button. This allows full throttle to be used, and the revs are controlled

by the traction control. This means you only have to balance one foot instead of two.

The system uses a secondary rev limit that removes itself automatically when the

rear wheels are within a set percentage slip of the front wheels.

The Launch Control rev-limits can be programmed using two methods depending

upon whether you have access to a laptop computer.

The Launch Control has two different rev-limits that can be set, WET and DRY. The

wet rev-limit only works when the switch is positioned in the WET position. All other

settings on the switch use the DRY launch.

1.10.4 Launch Procedure

Button Initiation – Stop the vehicle and press the launch button once leaving the

adjuster selecting the desired percentage slip.

The car will then rev-limit between the programmed soft and hard cut limits. The revlimit

and launch control strategy depends upon whether wet or dry settings have

been selected with the adjuster.

After 2-3 seconds the car should be settled on the Launch Control Rev Limit. If it is a

turbo car the boost pressure should be gradually building up.

A common mistake is to bang the clutch in and instantly spin the wheels. The first 10

metres is the most critical phase, even a small amount of wheel spin at these low

speeds is very high in percentage terms. The clutch should be slipped whilst not

breaking traction, but not too much as to impede forward progress.

If you can't slip the clutch, then change it for one you can, you are losing out, here is

why :-

The clutch can be used as torque converter. The torque curve on a race engine is

going to be biased towards higher rpm, at low rpm there will not be a surplus of

torque over wheel spin. Therefore the engine needs to rev before it can accelerate

the vehicle at a decent rate. The clutch translates this high rpm into high torque.

On a low powered engine that cannot spin the wheels in first gear, the slipping clutch

translates the stored momentum of the engine into torque to artificially boost the

acceleration in the first few metres.

On a high-powered vehicle, the slipping clutch prevents the wheels from initially

breaking traction, the most important factor in a good start.

If the car “bogs down” or has too much wheel spin adjust the rev-limits to program

the perfect start.

did any of you guys have a issue with miss fire detection atall

I had my zed all done bodywork perfect and new engine that cost 5k

 

driving somewhere behind a slow car I booted the throttle auto kickdown whoosh I was in the hedge before I knew it :blink:

 

funny thing was I wanted to get a traction system a few months before but as it was quite expensive I...... not as expensive as reparing my zed....

 

now in retrospect I think if the traction kicked in it would have saved my zed..... im not the best driver but I was aware of the kickdown on the auto but this cought me out

 

I do like the racelogic that I have now fitted, its also customisable with the digital adjuster I have if I want a bit more leash to play if you like or I can just leave it on standard setting, this also apparently saves tyre wear when you boot it off the line...

 

personally I think it s one of the best mods for the zed but that's just me :biggrin:

sounds good mate I really do want to get it one day
