Target vs. Actual Boost

BimmerHausPerformance · 10-28-2019, 09:15 AM

I'm getting ready to do my MHD tune after I update all my ECU's but I was able to buy the monitoring license. Here is one of my first logs and I noticed that in second gear I'm not hitting my target boost at all, any thoughts? I do NOT have a charge pipe. I also DO have an AFE scorcher module so I know my ACTUAL boost vs. what my ECU is showing could be off as, from what I understand, the scorcher "tricks" the ECU and sensors and gives more boost than what is being reported... Thoughts anyone on this log? Thanks in advance.

I did notice the WGDC is up in the 60's when I'm not making my boost target. Shouldn't that go higher if it's trying to build more boost? Just throwing things out there.

Ditch the AFE Scorcher because MHD is all you need, and then log again.

That is the plan, just need to schedule the install, but I was wondering regarding the gap in the meantime.

Doing the Throttle Adaptation reset seemed to have fixed this issue.
