News to me, thanks for the heads up. It definitely looks like a much bigger PITA to install than the JB4 on my previous M4, which I was extraordinarily satisfied with.

Firmware in the first post has the basic map switching active now.

EWG "fault" is corrected by adding one extra wire to the harness. Fairly easy to retrofit. Email us if you need directions on that.

Does this clear check engine light caused by catless downpipes?

No. Old versions did. New version can not due to EPA.

Just finished my first test drive after the install. The installation was actually very easy. It probably took less than an hour.
The car is significantly faster. It pulls with a force that actually makes me nervous about the longevity of the engine(but not enough to uninstall 😁 )
For $1k this is a no brainer to me.

You could ask Terrry if out of USA units can be set up to clear the code.

Yeah sorry, I’ve been so busy lately but I did do a Dragy run with my JB4 Map 1. 0-60 in 2.87 and a 1/4 mike in 10.78sec. Certainly not record breaking times but that was literally my first and only try. I’ll do a better comparison at a later time where I turn off the JB4 tune and compare that with the Map 1. Needless to say, it feels fast and it is fast.
