Cobb stage 2 35xdrive build thread.
I'm running a Cobb on my n55 x5
Just out an ER downpipe on, and I. Stage 2 I'm getting the same boost as stage 1 which is about 9.5. Cobb said both the maps are the same just stage 2 has DTCs off so no CEL comes on for the downpipe. Since these off the shelf maps are really for the e9x/e8x platforms, and the e7x has a considerably larger intercooler, I decided today to load up the stag 2+FMIC map. Guys, holy :wow: 17 PSI and loving it. With my bms intake this thing is howling and the downpipe sounds awesome. I came from a 335 with jb4 (but I did switch to Cobb for a short while) and I had an FMIC and Downpipes so on Cobb I never tried the non +FMIC maps. On the n54 with jb4, you got more boost with map 2 which is for downpipes then map 1.......but on Cobb on the x5 n55 it seems to not be the case. I never tried anything but map 2 aggressive +FMIC on Cobb on my 335 so I do not know the behavior. I'm just puzzled as why anyone would install a downpipe for stage 2 if the Cobb tune isn't going to give anymore boost. Yes I know. I'm prob the only x5 35xdrive owner with a downpipe I beat a e90 jb4 335 map1 and a f30 328 jb4 map 1 in a pull tonight. |
any EGTs?

I was considering flashing my ECU with the Cobb but when I emailed Cobb, they said that they were no longer supporting the x70 N55 platform. Were you able to arrange for them to make a special map for you, or are you using 335 n55 maps?
