jb4 questions

robert2125 · 03-02-2015, 12:40 AM

Is anyone still running the jb4 iso 5.5? Any issues? I've been doing alot of reading and it's like 50/50 some love it an others are having issues. Just would like anyone's input on if they currently running the iso. Thanks

How do you like the Jb4 with the Alpina B3 flash?

It's a must-have for a tuned 335 IMO. It makes the car shift aggressively when you're in DS and M modes. The regular D mode becomes an economy mode with low shift points.

I'm still on ISO 4, never updated it cuz it's been working just fine and dandy.....

how do you know if you have ISO or not?

Also, if u purchase a new jb4 from bms, will it have ISO?

What is the difference?

You have to clip the diode yourself, so you would know if you are ISO. They do not come ISO new for N55.

I've been ISO for 3 years and running 5_5 since its release date. The car and tune are solid, very smooth.

The only issue I've ever had was after adding the oil catch can. If you install an OCC, leave the heater wire connected to the PCV assembly, this will prevent the water pump from randomly turning on.
