ECUTEK = Adjustable Traction Control

DarkJak

Super old thread but actually one of the first results if I search on Google (and not seeing much newer here)
I wanted to add my experiences with my Z which is currently being tuned by Eugene on the rotrex kit, and traction control.

For background, I always tracked my car with TC off, run an OSG LSD, and have also been tracking/autocrossing a 2007 Exige S with Lotus OEM traction control that behaves very similarly to motorsports TC, but my year didn't get the adjustment knob for controlling slip. So it's always targeting what feels like 0 slip.

The Ecutek TC is a huge step up from stock. Where stock would cut power for what feels like a full second and be extremely jarring to the car, to the point of inducing lift-off throttle effects, the ecutek TC actually behaves like a sort of ok mimic of the Lotus TC.
However, it is a bit slow to react. It seems to be easy to blow by, RPM wise. Like in 2nd gear with the SC, the car will pretty much spin up to almost redline before TC kicks in.

In 3rd, the TC usually has a chance to intervene in a meaningful way, and does an ok job at limiting slip while still allowing power.

4th, I haven't gotten wheelspin yet, but have only been testing on the street in a straight line.


The real test will be how it behaves out of corners. The Lotus TC, I can peg the throttle, car car will cut spark/fuel as necessary to keep the tires from slipping, and I can get a corner exit maybe 90% as good as optimal with minor slip. Better than I could get while I was still learning the car.
