Your ink isn't even dry on your E90 post application and you are posting this, WHY ? You are not a moderator, chill out dude. An apology might be nice!

Sorry guys, no chance to pull logs yet. Between work and a week old newborn (and the couple weeks leading up to his birth) I have been running non stop. Very eager to see them myself so I will get to it, hopefully soon!

Good stuff, I just installed my new JB4 yesterday same feeling. I think it's even getting stronger each cycle after I drive and shut off the car. Yesterday after I first installed it was pretty good but nothing amazing. Drove it a few times yesterday, and then this morning it felt way faster.

We're you supposed to splice any wires

I got g5 ISO jb and car is hesitating and got limp mode

I just put all the connectors together, going to open it up today and try again

Try some 100 octane. It's expensive but worth it.

So many haters on this forum!
Glad your enjoying the new tune OP. Add some E-85 after you get used to the increased power and you'll be in for another fun surprise

I guess open forums bring out the best in people, especially when they can hide.

OP, enjoy the ride bro!

FYI the G5 doesn't come ISO'd. You have to snip off the diodes before loading the current 16b ISO firmware. Snipping the diodes makes the the boost isolated and no longer controlled by the DME. If you already know this then okay, just making sure because ISO is smoothe so you shouldn't have any problems if installed correctly.

Oh shit I just ordered a JB4 with G5 ISO board, does this mean I have to trim some cables now? Sorry for noob questions.

Don't grim any cables. Just open up the black control box and snip the two diodes. Details here

If you ordered the JB4 ISO then its already set as an ISO. Did you order from me? If you did I only ship the G5 as an ISO board.

If ordering off my site they only come ISO so for anybody that has ordered off me in the last few months they would have gotten an ISO G5.
