MaxxECU MDash

Fast and reliable. Don't believe all the reviews as this app works flawlessly on my Android head unit. The determining factor is the type and version of Bluetooth the head unit has. Works great on my Atoto S8 Gen2.

my only issue is the readings in the app doesn't change on startup like ( lambda stays 1.700) even when my car's engine is running unless I close the app and open it again, when the app opens I find that some of my gauges have disappeared even though it is saved, overall best ECU and dash ever.

NOT WORKING!! Please be aware that most head units with android will not be able to connect to the maxxecu = you will not be able to use this app in a streetcar, unless you use it on your phone or Tablet like Samsung galaxy. Really a shame, other than this the app is fairly good. But for this reason I give it only 1 star, as I build a street car with MaxxECU specifically to be able to use my head-unit as extra dashboard.. So now I have to figure out a way to mount a tablet also to display the information I need on my 800 hp turbo street car, where I really need to keep an eye on things. In hindsight: I guess i should have stayed with ECU Master, There the Bluetooth works. (my car was actually running ECUMaster Black, but I changed to MaxxECU Race) -- I have informed MaxxECU of these issues, and asked them to update their website + here on google play, about the APP and ECU Bluetooth limitations..
