TCEuro BMW Gauge Kits and Data Acquisition

Information is one of the most important tools in making your car faster, handle and brake better, and just be more reliable. Supplemental gauges have long been an easy and effective method of gathering and monitoring data on how the engine is performing, cooling system performance, engine tuning, oil pressure and temp, chassis dynamics, and just about anything else you can think of. Race teams employ teams of data engineers that study and articulate changes in the never ending quest of going faster.

Data acquisition and interpretation does not have to be a black art, however. We offer products that collect and present vital information in an easy to understand display. Think of these as smartphones for your car - sophisticated, touch-button operation, easy installation, and immensely valuable.

TCEuropean was founded in 2021 by two University of Michigan Mechanical Engineers passionate about BMW and the community of BMW owners. Currently specializing on the E30 and E36 chassis, they soon realized that their dream was to upgrade, restore, and leave their mark on these iconic automobiles. A non-functioning E30 odometer is often a victim of failed odometer gears. Over time, these gears will fall apart leaving the odometer non-functional. These gears are designed to replace your factory gears returning your odometer to functioning condition. These gears are for US model Motometer manufactured clusters. The brand of your cluster can be found in the center near the check control light.
