New! For OBD2 vehicles only. The RacerDataDisplay plugs into the diagnostic port and communicates with the ECU. It's very similar to a scan tool, however it's a fraction of the cost and has added features for tuners... like an acceleration timer and fully programmable shift light. Plus, you have 4 screen colors to choose from... white, green, blue and red. Replace gauges all over your dash with a single digital unit with a 2 line LCD display. 8 different pages show different sensors. It also reads and clears diagnostic trouble codes. So, if your CEL is nagging you, then you can read and clear the trouble codes... even while driving down the road! Get more info at www.racerdatadisplay.com.
