Great app

Great app overall, some sensors wouldn’t activate or read on app for my application, there seems to be a glitch or delay on selected gear function and there isn’t a function showing when vtec is actually engaged like previous Hondata app. But overall I like the dashboard and functionality of it better that the previous app.

Great App

To be honest I enjoy every single bit of this app, it is very good to keep track of your car performance and plus it’s a very cool detail to impress your friends,it gets bugs and defects as other apps do but, developers take care very quick, helped me when my heater hose broke on me on the highway, you can’t go wrong 💪🏻

Hondata app inaccurate boost pressure reading

Hello! I recently just installed this app with the new flashpro 6+ psi tune I just did for my 2019 Hatchback Sport 6 m/t but just 2 days ago it started givin me a readin of 14 psi boost pressure at idle in neautral! Then while drivin givin me a max of 36 psi but when I datalog obviously it's different & more where it should be. I love this flashpro & it's tunes but please fix this.. would really appreciate it & thank you for the great product

Developer Response ,

Please use the calculated boost pressure as the one in standard PIDs may not give correct readout. Let me know if you have any concerns. Thanks.
