JB+ and JB3

UCF 335 · 01-21-2010, 08:08 PM

I tried a search so before i get any "SEARCH before posting" posts I'm just letting you know i tried.

I put in JB+ with JB3 and what comes up is any thread including either JB3 or JB+ so it doesn't answer my question

I am trying to see if you can run a JB+ on top of a JB3, like can you run both tunes simultaneously

Thanks In Advance

no. you can stack a JB+ with a flash but you cannot stack a piggy with a piggy..

and why would you want to ?

I was just wondering if you could; just out of curiosity.

Right, the JB3 is a more flexible and aggressive tune so there would be no reason to install them together even if you could.

The JB3 will run the boost as close to maximum as you want... no reason for JB+ also. Flashes tend to be quite conservative on their boost tables so some people believe it OK to run a JB+ (purely as a boost controller) on top.

JB+ tricks the TMAP sensor only, JB3 tricks the TMAP sensor and a lot of other ECU values as well. Thats why it does not work.

An ECU flash tricks nothing, that's why you can stack a JB+ (flash version) on top of an ECU flash. This works very well and is not a believe. I test and log this since quite some time, works great.
