Hi all, I'm a long time reader but a 1st time poster. I've recently entered the realm of FBO on my n54 335i and have been getting interested in different tunes. I've been running a jb4 with a BMS backend up until recently and then decided to load the above map after finding some info on it. WOW what a difference is all I can say! Just so much power! Although I have a question after looking through my logs. I shall include a log but it looks like at around 3.4k rpm the WG duty drops to 49% before boost target is reached and never quite makes it to target for the rest of the rev range. It also seems to taper despite target remaining at 18.1 psi but the duty cycle only reached 87% It seems to pull back too early and fall short of target as a result throughout. I'd love to know why because it would seem there is room to allow it in the duty cycle. Any input on this? Btw, I still have my jb4 plumbed in on map4 with setting 4/3 to give boost to the DME. ps, sorry about the pdf... I couldn't upload a CSV

Upload the csv onto datazap.me

Ah I see! http://datazap.me/u/jamhot/jb4?log=0&data=1-4

There may not be any issue if you are meeting target load, which doesnt appear to be in these logs.

Target load is the primary focus for these tunes. Target boost is irrelevant to a certain degree as it's considered a maximum goal. (from my understanding).

Target and actual are two different things. Yes, we like to be close to target, but that's not always the case as the variable (target), can be set too low and doing so would cause issues for some customers. You don't have anything to worry about. If you pull the JB4 and start logging with MHD, feel free to send me your datazap logs to WedgePerformance@gmail.com and I'll take a look at the additional parameters MHD logs.

v6 maps will follow requested more closely.

Are the V6 maps available??? Be great if so
