ABS light

Had an exedy organic clutch fitted on wednesday so have been trying to bed it in a bit. launched at around 4000rpm earlier with antilag on. Wheels span slightly in first then I changed into second and seased off the power. A couple of seconds later the antilock brake light comes on

Anyone got any ideas? Its an sti3

possibly, might even be as simple as a loose wire connector

Found this info.

Quote:
Anti-lag systems retard the ignition timing so unburned fuel passes through the engine and, instead of igniting in the engine, ignites in the exhaust manifold, and spins the turbo over.

The air needed for this combustion is provided by the standard throttle body, which is opened to a greater extent than normal whilst anti-lag is running...thus the reason it has a solenoid to keep the throttle open

The ECU uses an idle control sequence so that once you've set the target idle speed, the anti-lag will cut a spark in a rotational sequence with each cylinder, which is why they idle so lumpy, and thus the reason its called rotational idle. If there was no rotational idle, the engine wouldnt idle at all, because the throttle is so far open that the engine would just rev.

The theory is, as soon as you open the throttle, you have full boost and no lag
