Hello everyone! I am developer of vent gauge for BMW's with m52tu/m54 engines. Here is all in one gauge, can provide you such data as: rpm; temps: oil, engine, intake air, automatic transmission; oil pressure, EGT, AFR, boost from vacuum up to 2 bar of boost, knock sensors information, Mass Air Flow, injection time, ignition timing, speed, acceleration time measurement (0-30, 0-60, 0-100 kmh), vanos data (for m54 ony), can do graphs of data. Easy plug and play installation - OBD2 plug + external sensors (EGT, AFR, Boost, oil press). Perfectly for boosted BMW with m54/m52tu engines. OBD2 DATA WORKING WITH ms43, ms42 ECU's ONLY. Here is some pictures + video review. If you are intrested - you are welcome!
