Introducing RatioShift! Designed for the enthusiast and built for the race track. RatioShift enhances the driving experience. Originally designed as a simple shift-light to keep the driver's eyes on the road – it quickly evolved into a multifunction auto dimming temperature reading powerhouse. No more are the days of constant paranoia where the unpredictable could happen; leaving you with a warped head, low compression bavarian hunk of aluminum.
Keeping your eyes on the road RatioShift will constantly monitor rpm and coolant
Ultra Bright LEDs
RatioShift utilizes latest LED advancements with ultra bright RGB LEDs. With auto
dimming at night and full brightness during the day, these LEDs look awesome.
High-speed 64 MHz processor releases the full potential of RatioShift. With high refresh
rate and precise Algorithms, RatioShift is always ready.
RatioShift has three user programmable temperature notifications – cold, overheat
warning, and extreme overheat.
With a sleek appearance RatioShift is the only shift light designed for the E46 dash in the
With the included straightforward programming card, easily adjust RatioShift's 10
programmable settings. Each setting is stored in memory – only requiring an initial setup.

Full Platform Support
RatioShift supports all E46 engine and DME platforms: M54, MS43, MS45, MS45.1,
S54 and MSS54.
Installing RatioShift is very intuitive with only 4 wires needing to be connected: power, ground, rpm and coolant temperature.
RatioShift's wiring harness runs between the gauge cluster and dash. Once behind the dash, power and ground tap into switch power from the gauge cluster. The wiring harness then moves down to the footwell and through the firewall into the ECU box where rpm and coolant temperature are tapped.
For detailed installation, videos and an instruction booklet will be supplied. If you've installed angel eyes before then you're good to go!
