I want a cobb v2 or v3 to stack with my jb4 ! Show me your cobbs !

[fredcase]

Uhm, cobb doesn't stack well with jb4.
There are jb4 specific flashes to accomadate jb4.
They can be loaded via mhd, a much more modern, cheaper, and updated version of cobb flash able through an android phone. Cobb is pretty much obsolete on this platform.

Well mhd is filled with bugs for now....my friend has a cobb bef + jb4 and his logs are near perfect....im sure mhd will be better in the long run but for now this setup is the best for safety and power imo

I have jb4+mhd backend flash, my logs are also near perfect. And i run map 7, 19.5 psi.

I have tried almost every tune and combination.

I did like the cobb by itself with linear throttle. That was easily the smoothest.

Jb4 with mhd backend is the most versatile, and powerfull.


Mhd ots maps i feel were garbage, but Mhd as a software is amazing.

My logs arent very organized. You can search my same user name on the site geared directly by and for jb4 users. I got a few threads over there.

Can you elobarate on jb4 + mhd bef plz ? Isnt jb4 only faster and mhd bef is not powerful due to super low timing ?

[Bours]

N54 or n55 ???

[fredcase]

N54.

Jb4 plus mhd bef (back end flash)

I run the race bef. It has more aggressive timing.

Its winter and i don't play around much outside jb4 map 1. On my studded 17" tires.

I will try to dig up some good logs for ya.

Ah im n55 ! The bef is not on point yet like the n54! I found your logs on jb4 website. Looking good for 94 gas . 17 psi is my limit too. I prefer running map 2 with clean timing. I just need a good bef for trims and afr !
