VZ Executive - Fitting Traction Control

[bigdaddycool]

I'm after info if anyone has it about getting Traction Control fitted.

I have a 2006 VZ Executive and in the rain it's an absolute *****. I dont have LSD, it may be coming but for now i'm focusing on traction control.

My dad has a 05 VZ Exec with a 914 Police Pack which has the traction control. Does anyone know where I can find info, get it fitted, aftermarket traction control units etc????

Holden are hopeless ....... Has anyone fitted aftermarket traction control or maybe installed it from another car.

My thoughts so far may be to replace the ABS module in the engine off a SV6 model? I assume this may have Traction Control built in?

I need info.

Get better tyres.

[f1tzy]

Learn to use the throttle better. I had a manual vz ute and never once did i have an issue in the rain unless i put the foot down

[bigdaddycool]

pft. fail. I have gotten better tyres..... 19" Traction AA. I used to have traction A ......... which were even worse. the new tyres arnt so bad. I think it's a combination of not having LSD, being tuned and having the front tilty wheels........

But again, I'm after info about traction control not opinions really...

How much time do you have?
You will probably have to change the
entire loom to one with TC.
Also the 4 channel ABS module.
LSD might be a cheaper place to start.
Perhaps with a taller final drive.

Traction control and LSD are not the same and perform quite differently. Having a "lose" with a limmy in the wet can catch you out so quickly that you have hit something before you have time to react. It can be much more tricky that a standard diff. LSD only shifts the power to the wheel with the greatest traction, it doesn't limit the power being fed to the wheels.

That's where TC works. It detects the wheel starting to slip and applies the brake rapidly to restrict the wheel/s from spinning. It also limits the amount of accelerator that is being applied. An LSD does neither of those things.

I've experience both in cars of mine over the years.

I'll take the TC every time.

To the OP, I can't help with what you need - the TC is appended to the ABS, but exactly what's involved, I don't know. Perhaps an auto electrician or brake specialist might be able to assist. Whatever you need, it will be electrical and probably won't be cheap.

Can you compare your dad's car to your own under the bonnet/fuse box/rear wheel brake assemblies etc?

generally speaking an LSD will make a car more taily in the wet not less.

im keen to find out how the abs unit will pull engine timing,

id be thinking more BCM... as long at the ECU knows whats going on


id swap BCM's and see what happens...

[ashbox]

same as above, from what i understood commodores didn't apply the brakes to stay in check. falcons yes commos no.

[Benboy]

Forget it. Too expensive, too hard, too much trouble.

the BCM has nothing to do with trac
the ABS/Trac module sends a serial data signal to the ECM that reduces spark advance initially to try to reduce wheelspin.

i went from the 3.08 single pegger that did the same, would bake up easy as, i then fitted a 3.46 lsd, i tell you what, even with the different shorter ratio i find it almost impossible to get the wheels to spin in the wet, this is on michelin 245/40/19's, around corners the diff will lock and skip the inner wheel under power, but very very rarely it gives out both wheels

so this would then be adjustable with the bosch abs software??.... hmmm never heards of it like that

Does your VZ have TC?

[bigdaddycool]

Yea well my thoughts are a LSD helps make power in the dry reducing the stress on the axle etc........... if u make too much for a single pegger.......... which i have atm (causes axel trunk) ......... but i figured in the wet atleast if the wheel slipped it'd move some power to the other wheel which would "have to" help somewhat.......... two wheels producing power in a particular direction would have to help over one.

traction control would probably ultimately sold my wet situation tho ........... truth be told if holden had made the ESP better it'd probably have helped as well.

pft i'm at a loss really.......... lsd seems the cheaper way to go possibly. i think either way i'd be looking at the $1500-2000 mark

just look for a second hand unit, on ebay, thats what i did, its a risk though, i got a good one, i.e its nice and tiht still, but see how you go

[coop3r]

this is something i have been thinking about too.

i was told the exec and the acclaim share the lux bcm so i'm assuming it would be an easy fix. does anyone know if the wiring is there and just needs the switch put in. considering the cop spec exec's have 4 power windows and traction control it might be an easy fix.

anyone got updates?

[torana355]

My SV6 is tuned and has the LSD. I NEVER use traction control because it is not implemented very well on Holdens, it cuts all the power and you go nowhere. You are much better off using a bit of throttle control. I can understand how hard it would be with a open diff though.

[danja]

Parts I'd be looking at include ECU, 4 channel ABS module, rear wheel speed sensors, wiring loom and switch.

To be honest I'd look at LSD/different car.

standard exec are fitted with all of the above, just without the switch part

nope exec and acclaim share the Level 1 (base) wiring loom with the Mid spec bcm, mid spec bcm is capable of running all of the above, just not climate control

the low spec is only used in the base utes, tonners and crewmans

[coop3r]

standard exec are fitted with all of the above, just without the switch part

so does that mean if i get my mates vz exec and pull apart the centre console i'll find a plug that can be utilized ?

Non TC model's have three channel four sensor ABS.
Traction control models have four channel four sensor ABS.
You need 4 channel so the ABS system can apply the brake
to relevant rear wheel during loss of traction.

afaik the vz's all have 4 channell abs,

Brakes:
•Front: Ventilated disc and finned twin-piston caliper.
•Rear: Disc
•Anti-lock Braking System (ABS): Bosch ABS8 - 4 sensor, 3 channel (front left, front right, rear). On vehicles with traction control 4 sensor, 4 channel
•Front (Monaro): 320 mm x 32 mm Ventilated disc and larger more rigid new C6 finned twin-piston caliper.
•Rear (Monaro): 286 mm by 18 mm ventilated discs

Traction Control:
When sensors detect imminent rear wheel spin, engine torque is reduced. If one wheel is about to spin, braking is applied to transfer torque to wheel with better traction.
