User reviews

Does not work with VLinker

Probably is a great app, it appears really well built, but the developer advertises—and you can see the VLinker MC+ however when it tries to connect it ends up disconnecting. Unable to use.

Best CAN data viewer!

Awesome app, combined with canserver its a great way to see all the data on your Tesla’s CAN data.

Useless on 2024 Model Y!

Gives incorrect LV battery voltage & current draw. Never - after multiple attempts & long drives - populated all cell voltages.

Response from developer

tes•LAX is a generic CAN bus monitoring and visualization tool. As is explained in the app listing and in the app itself, the developer does not actively respond to the frequent changes made by vehicle manufacturers to CAN bus signals. The Extra Strength feature set allows customers to maintain the signal information themselves in response to such changes. On a best-effort basis, we will occasionally update the decoding logic for some vehicles when new information is available from the community. Please reach out to support for further assistance.

Not user friendly

Can’t find anywhere where it shows you how to connect your car to this app. Maybe I’m just an idiot if it’s there in the app, they don’t make it easy to find. if you cannot connect the application to the car it’s useless so until I figure out how to connect my car to this, it’s useless 19 bucks wasted

Response from developer

Sorry you are dissatisfied with your purchase. Core functionality of tes•LAX is completely free and the app strongly recommends that you test your hardware accessory installation and connectivity fully before choosing to unlock additional features. Please consult the app's help menu and the tes•LAX website for documentation and helpful videos.

Gut gepflegte App insbesondere für Tesla

Bildschirme können umgestaltet werden, so dass perfekt passende eigene Ansichten möglich sind.
Mittlerweile ist das auch für Diagramme möglich, top.

Die App und die Can-Bus-Parameter werden gepflegt, so dass die App auch in Zukunft noch sinnvoll nutzbar ist.

Die HUD-Funktion mit gespiegelter Darstellung für die Reflektion über die Frontscheibe ist ein nettes Gimmick.

Leider hinkt die In-App-Hilfe der sehr aktuellen Version auf der Internet-Seite des Programmierers hinterher, so dass in der App der Hinweis auf den sicheren und sehr schnellen und trotzdem recht günstigen vLinker FS mit classic Bluetooth für iOS fehlt, das sollte unbedingt nachgetragen werden.
