Which JB4 setup?

BMWX1-35i · 08-17-2015, 11:06 PM

Ok, I'm ready to take the next step and move from AccessPort (I will be selling it) to JB4. I need some guidance and recommendations. My mods are below.

Cobb V3 with Wedge Performance Custom tune, VRSF FMIC, Cobb DP, Berk cat back, VRSF charge pipe, HKS BOV, Hotchkis FSB, Koni FSD, EBC Brakes & slotted rotors

buy JB4, install jb4, set to map1, log and post on other forum in support section.

looking at your mods and assuming 93+ oct, map2 should also be OK, but start with map1 to be safe and ensure no mechanical issues exist.

good luck brother

Even before I had the amount of engine mods you do, I was using map 5, and I didn't experience any issues. And hell, I STILL don't have an aftermarket FMIC, which you do. I don't think you will have any issues if you were to choose map 5, and I think you need to run map 5 to account for the BOVs anyway.

I have had great luck with Map 5. 91* is the best gas I can get so I let the learning map tell me what is safe.
