Upgrade your car with our fully programmable ECU in a matter of minutes without any wiring nightmare.
Designed to be a plug-in replacement for your BMW M50 or S50 equipped car. It will control VANOS if you have that on your particular engine.
The M50 and S50 engines are typically found in the BMW e36 platform. The M50 is also used in the e34. If you have an e30 or other car with an engine swap, if it used the original M50/S50 engine wiring harness, it will work with this standalone ECU.
