Car: X3M40i
Default X3M40i: Bog and throttle closes randomly - 05-10-2018, 09:42 AM

Hello, I just got the JB4 for the B58 for my X3m40i. I used to run MHD on my N55 135i and I decided to make the switch to BMS for the B58 because I appreciate all the support Terry is giving reading out our logs! Love the Bluetooth feature and the quick map changes.
My car is fully stock on 94 octane gas. When I run Map 1 I feel no change. On map 2 I feel a little more power. I tried Map 3 and there is a major engine bog, I don't really know how to read the logs but I do see my throttle closes a little on 100% pedal. I also tried map 5 and it's smoother than map 3 but still, I get issues with the throttle. On map 6 at 17 psi flat boost it's not soo bad but on the logs I still see the throttle closing.
I attached the logs in csv. Hope someone or Terry can help me out here! I'm waiting for the BMS intake to arrive also. There is so many parameters I do not fully comprehend.
I attached 4 map 6 at 17psi flat boost logs and one on map 2. Hope I logged well enough... it's my first time logging! Let me know if you see something I should change in the parameters! Also thanks in advance!
