Need help: JB4 328i guys

Seraphblade@sg · 06-01-2016, 04:30 AM

Hi folks,

Can anyone do some logging on the JB4 (on map 0)? I need to take a look at the stock boost levels between the target and actual. Seems to be having some issues holding boost at the moment.

Not sure if there's a leak, problem with the DV+, FMIC or CP =(

Use map 4

Attached is a table pulled from the ecu.

Can I confirm this is the target boost values? Looks low..

Anyone any clue about the above values?

It is the load vs rpm table. Just wanna confirm the values inside is boost (bar)...

3rd to 4th or better 4th to 5th gear wide open throttle pull from 2,000 rpm to redline with another 1000 rpm in the next gear. Log it and post the csv file and chart
