JB4 tuner non USB useless
Bought a JB4 for my 2020 accord 2.0t and when installed makes car feel less responsive and maybe slightly slower. I bought the base device without the USB because it was $130 less... if anyone can tell me the difference between the maps you can get on the USB one and the preset map you get one the base device that would be great.

Moved your post to the Honda forum. Map1 is pretty mild but should be a noticeable gain. You can use the $35 data cable and free windows software to change up to higher boost maps. The blue tooth adapter is great also but it's $169 for the app and adapter so a little more money.

Are you sure that without the bluetooth cable its on map 1? Because I really don't feel an increase in power whatsoever. I ordered the bluetooth cable so im going to try connecting my phone and selecting a map manually.

It should be unless a mistake was made here, either way the app will let you change between map0 and map1 for a side by side comparison. And record engine data so we can check for timing pull, boost levels, and anything else that might indicate an issue here.
