I’ve just finished installing my Race Logic Traction Control unit and I was just wondering who else as it fitted and what you think about it?

do these things when set up, stop your wheels from spinning up on hard throttle?

They cut the power down until you get grip then give it back so on, also if you were going around a corner and you plaint you foot in the shag pile a bit to soon it stops you from losing the rear end completely. Most of them have launch control.

I have it - brilliant system & love it! It makes the car so much safer to drive in the winter & the adjustable settings still allow you to have as much fun as you like ;)

Not installed mine yet. Is it hard to do?

It took me about just over 2 hours dew to a striped out track car, I found a walk though from the twinturbo.net site which i'll email it over to you?

that pic of the control unit looks a lot different to the little control box with a 4 position dial and green launch button that it came with when i had it fitted to my car many years ago :-)

What are these worth out of interest?

Ive got one installed, though mine is just the little turn dial, no green button for launch control, great bit of kit still. cuts the injectors when it senses wheels spin from the ABS unit, giving nice little pops and bangs down the pipes lol

 

I can install the little black box with the lunch button if i can find one going, and then just update the software

 

as for what are they worth, brand new between £500 and £700 depend what one you have, second hand, not sure.

 

The price is more dependent on what software the ECU comes with and the box that controls it, but the ECU's are fully programable as well to give you total control over it.

I see so this'll be fine with both stock ECU and AEM EMS?

it doesnt connect at the ECU, you plumb them into the engine wiring loom, you take the feed of each injector and splice in the traction control ECU between them, then splice into the ABS cables at the ABS ECU doesnt matter what engine ECU you have, the racelogic has its own, and will only by pass the injectors if it gets feed back from the ABS that the wheels are slipping.

 

Basically like this

 

Injector > Injector wire > racelogic traction control ecu > injector wire > ECU if that makes sense lol

Ok I see, what if the car doesn't have ABS (ie. NA)?

That sounds like the best option ever! Really would be an all round car then!

bacon samich on the go, cant beat it lol

 

if the car doesnt have ABS, they provide wheel sensors im pretty sure they do.

cheers mate

No problem, i have to say, now ive got it installed (came with the car me a lucky bugger :D ) its well worth it and something everyone who owns a zed should have. and yes you can turn it off lol

Wise words my friend.

 

I've got the digital version and you can (via the software) turn the little green led into programmable gear change indicator. Which is nice..

One day your car will leave the drive so you can try it out lol

Think you should swap your digital controller for my analog one so i can have launch control lol

Are you not keen on the traction control that comes built into the AEM unit?

Is that traction control or launch control? I'd best go and take a look at the manual before taking the plunge I reckon..

Looks like the AEM works differently in that it doesn't use sensors but instead using Speed vs RPM and Gear calculated speed, from a pre-determined set of parameters under ideal conditions.

 

 

The AEM Universal box uses engine acceleration as the basis for TC. I was going to cut and paste from the software manual, but it's long and full of tables/maps. The downside is that maximum acceleration under ideal conditions is logged and used as the basis for TC tables and sensitivity. It seems like this can change with different tires, gears, surface conditions. So, TC probably needs to be tweaked when major traction upgrades or downgrades occur. The good news is that AEM TC works on damned near any vehicle with or without wheel speed sensors. From AEM:

 

Traction Control Tuning Procedure

1. If the vehicle has a manual transmission with no gear position sensor, use the TC Gear Ratio option and define the Gear Ratio Table as described above. If the vehicle has an automatic transmission with a gear position sensor, select the option TC Gear from Sensor.

2. AEM recommends starting with the following options settings for calculating Raw Engine Acceleration:

TC Speed/Time = ON

TC Timebase = OFF

3. With the option Traction Control turned off, log the parameters Engine Accel raw and Engine Speed under hard vehicle acceleration through each gear with optimum traction conditions.

4. Review Engine Accel raw to determine a maximum acceleration rate. Define this value using the option TC Max.

5. Use the sensitivity tables to adjust the acceleration sensitivity at varying engine or vehicle speeds. If vehicle speed is used, the option TC vs Road Speed must be enabled. The parameter Engine Accel Rate can be viewed or logged to see the results.

6. Once the sensitivity tables are defined and a good signal for Engine Accel Rate is established under optimum traction, define the trip tables. This should be just above the values for Engine Accel Rate under optimum traction conditions in each gear.

7. Start with the TC Ign Retard option by defining the amount of retard (20 deg is a good starting point). Define the TC Ign Retard Resto option (2 deg is a good starting point). These settings will retard the spark timing 20 degrees when the trip limits are exceeded and will restore the timing 2 degrees per engine revolution when the accel rate falls below the trip limits.

8. Enable traction control by selection the option Traction Control from the option list.

 

 

I'd use the launch control function maybe but this ^^^^ seems like it could open a whole can of worms under different conditions
