Also, in the app or windows application, the firmware version will show (backslashes may be flip-flopped):
60//5/5
Took forever to find the info one the BMS/N54 forum or here. Eventually did on N54.

Pause the video during the run. R starts with 3km/h higher speed. By end of the video the GTI is 10km/h faster.
Yes, taking into the consideration that the R is a little bit heavier, I think that my car must be pushing around 300hp with a JB4. When I ordered it, I told myself that I will not fiddle with any of the custom settings (I was the one emailing you, if you can deliver it to me with map 2 already selected), but now I'm curious if we can squeeze some more juice out of it on map 6. Guess it's time to do some logs then.

Does anyone know of a replacement harness for the obd connector? I noticed this today after installing into my car.

My JB4 is currently out for delivery with USPS and I’m quite excited to throw it on tonight. My car has 53k miles on it. Question is, will I be fine running on Map 1 with 93 octane on the stock plugs, or should I wait to install the JB4 until I get fresh plugs in? Only other mods are IE intake and Clubsport S muffler. Excited to put this on and get a Map 6 set up.

Map 1 is ok on 93 gas. Are you still on the original plugs?

Check that firmware is up to date before you switch from map 0 to map 1
Are they original plugs? Should be fine, it will just reduce your results with worn plugs

Thanks guys. Yes they are original plugs. I’ll be replacing them at the next oil change.

JB4 up and running. I noticed some stuttering at low speeds, read up and found some new Firmware. Updated via Bluetooth and now it is smooth sailing. It is also Droning a lot less than before, still getting a Vibrant Resonator installed tomorrow.
Logs inc soon.
