Jb4 questions
 
Hey there,

I came from a fbo N54 with a JB4 g5.

I loved it and I usually ran map 5 (auto tune). Long story short the cars sold and I have the C400 now.

Is there an auto tune map for this platform? I just installed bms dci, is the JB4 learning the difference of the dci? I installed amg 450 mufflers and did a rear resonator delete, does it learn about this flow and less restrictive exhaust?

Now Iím thinking about buying dpís but am thinking do I need an ecu tune for all of this? I feel like on my n54 it was all plug and play in terms of upgrades and the jb4 learning, can the same be said here?

Thanks

Phil

No full autotuning map yet, but we've got a solid map lineup. You won't be disappointed. Yes it adapts to intake/exhaust mods.

On dp's not tested since they are illegal, not suggested in the USA. But I expect it would run fine just have a CEL in dash.

Thanks for the reply Terry, I appreciate you taking the time!

By solid map lineup are you implying new maps are coming or talking about the existing maps?

If itís new maps, thatís super exciting!! Is there an eta or approximate timeline of when we can expect them?

Iím hoping the jb4 and dpís work well together as they are pretty expensive
