Does anyone know if it is possible to install a 2 step rev limiter or a wot box on a 2000 BMW M5. I'm looking to buy and install one for my car
I'm not aware of any off the shelf products that will fit the e39 M5. Keep in mind that a 2-step or a WOT box is for a turbo car. The point is to spool up the turbo for a launch, or keep the turbo spooled while you shift. There isn't much point on a naturally aspirated car like an M5. A 2-step launch control will also dump lots of fuel into the exhaust, which can destroy your catalytic converters.
Yes you can buy a wot box there are many universal off the shelf my personal preference is what I’m running n2mb wot box it works great not a lot of diy’s tho
