[TC] - Traction Control setup

[Wuniek]

Hello,

can i ask these of you that already setup this function to share example config of it ?

HI
First you need to determine what is dRPM when you have no slip per gear.

Once you got it please note is different per each gear you need to set correctly table so yo have a correct resolution not to far towards high values.
Than assume that gear 5th for example is your 100 percent dRPM and you will need to define multiplier per each gear roughly matching values (dRPM) per each gear..
Once you have it done you need to work on gear which you decide to use as 100 so no multiplier for that one.

On the table below values (TC Delta RPM) when you moving as fast as possible without slip for given throttle torque reduction should be 0 as you know that is no wheel slip all above need to be nicely blended to not make it to aggressive.

Thx for answer!

HI
First you need to determine what is dRPM when you have no slip per gear.

For beginning i want to set it up for first 3 gears and looking at the logs values are:
1 gear dRPM is bellow 20 (16-20)
2 gear dRPM is bellow 8 (5-8)

And when i have wheel slip on second gear dRPM is 20-40, i think something is completely wrong with this numbers because i move only at 2 first rows of Torq reduction table. Any ideas what to change to have bigger dPTS numbers? I think my gear scale should be inverted because now I’m hitting high values on 5 and 6 gear.

second gear

fifth gear

Your gear scale is too small.

You can also change sensitivity paramteter. The more the bigger dRPM is.

Thx!
i also received sample config from Kisielisodd, i will update this topic after tests.

PS. it will be really great if forum can accept Ecumaster files (*.emu*)

I think this post write very good!

Can someone suggest a strategy for choosing TC Sensitivity value? With 100ms, I'm reaching TC dRPM Raw of about 370 in 1st gear with no slip. It looks like full scale for this channel is 1000.

I'm starting out with 100ms Sensitivity and trying to set the gear scale so TC dRPM is around 100-120 for each of the lower gears. It seems sensible to tune this so fastest acceleration reaches near mid-scale on TC dRPM Raw for 1st gear and scale that for each gear to reach mid-scale in the Torque Reduction table (~130).

Can anyone offer their experience so far with setting this up?

It is snowing here, and I couldn't make it to work, so I thought I'd do a little TC testing. For some reason my TC dRPM is really jagged, as in not very smooth. adjusting the Gear scale helped, but as you can see in the image, Drpm will go from double digits to 175 in 0.2 sec. I don't see this in the other logs above... What should I adjust? or do I have an issue elsewhere?

hi
change sensitivity value

Hi have almost finished my new harnes for my s13 ca18det and i would like some advice.
Where is betere to take speed signal front wheels abs sensors, tacho out put or rear abs sensor its on the shaft
I want to have the best results operating tc.

Thanks

dump... i have tied up my harness

For gear detection you should take VSS from the gearbox sensor to maintain fixed ratio between speed and RPM

Thanks kuba.

Can i have also the sample so i can start to understand how this thing work. Thanks in advance
