JB4 Help

Hey guys, I just bought a 3.3 AWD G70, and it will arrive at the dealership on Monday or Tuesday. While I wait for the car to get here, I thought it'd be the perfect time to buy a JB4, as well as everything I would need in order for the JB4 to work correctly. I'm not super knowledgeable when it comes to cars, and even less knowledgeable about tuning. So besides buying the $500 JB4 for my G70, what else do I need to buy to make it work? I am less worried about the cost of all of it, and would rather spend more if that is going to make the JB4 work better. If yall can help me with a checklist of items I would greatly appreciate it so I can have most of what I'm going to need by the time the car gets here. Thank yall!

Get fuel wires, the Bluetooth hardware and the app and you're set.

Fuel wires? Talk to me like a child.
They allow the jb4 to adjust air fuel ratio. They aren't required but you will make more power with them. You can order them on the burger tuning site along with the jb4.

Just picked up a 2022 Launch edition G70. First mod was a JB4. Next mod will be to install colder plugs and turn up the boost. I did a few WOT pulls but am unable to decypher ther datalogs. I can read datalogs but i just dont quite understand how JB4 datalogs are read. Like.....I dont understand why my timing ign1 says 14 but ign2, ign3, ign4, all say zero.
Will post Datazap here if anyone can help me understand this log. THX !!!!

Datalog attached below
BTW its the last pull in datalog....

Ign 1 is total timing, 2-6 are timing reduction, which you basically have none to very little in the log. In other words, looks great and your fuel is good.

Thanks a bunch. I changed FUA to 1 so that I can now read Raw Timing across all cylinders. I am still on stock plugs running Map 2 with no issues so far. Also, how do I monitor Wastegate Duty Cycle because WGDC does not seem to be it because I am in the 60’s which is far too low. Is it PWM ? Or do I have to change any settings on JB4 ?
Thanks a ton !!!!!

Doesn't the Launch Edition only come in a matte gray or white? Yours looks like the regular white or possibly Siberian ice color.

Mine is a Matte White AWD Launch Edition. I think that photo was just one I pulled off the web. Gotta change it
