Switching from Racechip to JB4

BIMMERPOST
     Featured on BIMMERPOST.com
Hello guys,
Have a jb4 coming in soon, I've seen a lot more consistency with it. But i was wondering i have downpipes also on the way, i am going to put new spark plugs in, put it in Map 3 and fill E30. Does anyone with jb4 experience know if this will be okay? Please let me know

The jb4 is more aggressive than the Racechip, with a lot more features and flexibility.

you will be okay with the downpipe, but the Jb4 will not hide the code

What makes a good product good is its consistency to work, and the racechip for me was one of the most inconsistent thing I've ever seen. Sometimes it's work, other times it would fall flat on its face. Jb4 is producing better results, data, numbers. Also has more play room if i wanted to do an e85 tune, race gas tune, more variables to mess with. Just depends the quality you want.

I think I'm going that way as well. Unfortunately I think JB4 support has gone down hill over the years, but the product was awesome back in 2011/12 whenI had my N54 ride. I also don't like how we have to run the OBD cable, but what can ya do.

Good luck! Looking forward to your experience. Any chance you have a 6 speed?

If the OBD cable is not ran it defaults to Map1 while JB4 is hooked up to sensors.

I jumped. Planning to install in the next few days. Will also run the Fuel-it analyzer.

What do you mean about the OBD cable? You can run the Bluetooth version and you don't need OBD I thought.

you'll still need the OBD cable for the full Jb4 control

the Bluetooth replaces the USB cable not the OBD

Yes, it's a mandatory connection.

without it, the Jb4 will act as a stage 1 similar to the other piggybacks on the market
