Stoni's electronic Boost CONtroller,

designed for Volvos famous B21/B23/B230 turbo engines with Bosch LH-Jetronic systems.

SeBCON-Micro BT is a air mass based electronic boost-controller, designed for turbo engines with LH-Jetronic fuel injection system and conventional regulated turbochargers. SeBCON makes the boost adjustable via an PWM regulated solenoid which is controlled via the air mass flowrate messured by the AMM. The gain from regulating the boost via the AMM is an excellent throttle control over the whole engine speed range.

Power output on a stock B230FK/FT engine will be round about 190-200HP with a LH/EZK chipset and a SeBCON set to 0.9bar/13psi.

SeBCON is especially adapted for the following Volvo engines:
B21FT, B23FT, B23ET, B230ET, B230FT & B230FK

SeBCON can be adjusted also to other turbo engines by modifying the internal maps.
