Hi all,

I own a BMW M340 and I just bought the JB plus, i have seen that this piggyback does have a clock dial that can be adjusted the PSI. I have a couple of question because i'm quite ignorant with this thing.



1. what is the best PSI setting for JB plus in order to get the best result? does someone have dyno tests?
2. is it true that i must put my ECU asleep 10min before to connect the piggyback?

Waiting for answer before installing :P

I don't think a JB+ adds enough boost to make anything less than the highest setting the most powerful as long as you use premium fuel.

Yes, open your hood and put your fob in your house for 10-15 min and leave it there while you do your install so the ECU doesn't detect a loss of connection, which could be a signal you did some modding.

My JB+ came with max settings, is that normal? i bought the b58 version

Sorry to reawaken a year old post lol, did you have any drop off after install? I found the throttle lighter and noticible power increase upon first installing but it seems diminishined.
