You're going to want to feel how much more alive the engine is with our standalone. Even on a 100% stock car it makes the difference between feeling flat and boring to lively and exciting.
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 M52 equipped car. It will control VANOS. The S52 is identical to the M52 in the US market as far as electronics and controls.
The M52 engines are typically found in the BMW e36 platform. The M52 is also used in the e39. If you have an e30 or other car with an engine swap, if it used the original M52 engine wiring harness, it will work with this standalone ECU.
