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.
 
 
Key Features:
 
Active Monitoring 
     Keeping your eyes on the road RatioShift will constantly monitor rpm and coolant    
     temperature.
 
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.
 
Microprocessor
     High-speed 64 MHz processor releases the full potential of RatioShift. With high refresh
     rate and precise Algorithms, RatioShift is always ready.
 
Temperature Notification 
     RatioShift has three user programmable temperature notifications – cold, overheat
     warning, and extreme overheat. 
 
Design
     With a sleek appearance RatioShift is the only shift light designed for the E46 dash in the 
     perfect location.
 
Fully Programmable 
    With the included straightforward programming card, easily adjust RatioShift's 10 
    programmable settings. Each setting is stored in memory – only requiring an initial setup.

Electrical Protection
     With built in reverse voltage, over voltage and transient current protection RatioShift is
     designed and built to last. 
 
Full Platform Support
    RatioShift supports all E46 engine and DME platforms: M54, MS43, MS45, MS45.1, 
    S54 and MSS54.
 
 
Installation
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!
