Autronic SM4 ECU
In order to push big numbers, the stock engine control unit (ECU) won't suffice. Although I haven't started my forged engine build yet, the use of an aftermarket ECU with my current setup means the airflow meter can be deleted and some power and torques can be won! Another advantage is improved throttle response and the car can me mapped a bit more fuel efficient, lol.
Two friends of mine already use Autronic ECU's in their ST185s and are very happy with theirs, hence I opted for the SM4. Besides controlling fuel and ignition tables the SM4 also features goodies like ALS, launch- and traction control.
The kit contains the ECU, universal wiring loom, temperature sensor, Bosch relay and a serial cable
