R-Spec Performance Ltd is is now offering what we feel is the best direct plug in OBD2 multi display that is currently available, the new Shadow D-METER-PLUS OBD2 Multi-Functional (10 in 1) Diagnostic RGB Display PSI/BAR C/F. The pictures do not do this great bit of kit enough justice, the D-METER-PLUS is leagues ahead of other OBD2 displays in appearance, specification, performance and quality.
 
The New Shadow D-METER-PLUS OBD2 Diagnostic Multi-Functional Display has facility to read 10 different sources of vehicle information, including turbo boost, air-fuel ratio, DSG, speed, voltage, water temperature, etc. The unique OLED display screen greatly improves data visibility in any environment. This very impressive OLED display won't be disturbed by external light when checking important engine data etc compared with other inferior products that are currently being offered in the marketplace that still use basic LCD screens. The unique hidden button design of the D-METER-PLUS allows the user to operate the product discreetly and with ease, this also operates an optional seven-colour RGB ambient lighting with five-stage adjustable brightness. The ambient lighting can also be set to dynamically change with the driving conditions of the vehicle, increasing the driving experience and adding another dimension to this already fantastic product.
One of the most important functions of the D-METER-PLUS is the ability to enable fully adjustable warning functions against various engine information to provide the user with a high element of safety.
