Boost pressure matching ECU; nowhere near targets -
03-15-2017, 10:56 PM
Hi.
First time running logs in ages.. Just installed the new JB4 app for Android and flashed latest firmware 32_6b. Set traction control fully off and set to map 5. Am running BB flash from 2/23/16 but just noticed tonight that a new version was just posted.. Have JB4 set to 4/2 (not sure if I should have 4/4 since running BB flash)..... Did 2 pulls; one from 2nd and the other from 3rd.... Not sure why the boost attained is so low vs. target in some areas and close in others.. Was thinking if it was a leak, then I'd see similar loses across the board.... Have setup just as Terry has posted in the picture of the User settings... Running 93 octane gas, Active Autowerke Race FMIC, AA Charge pipe and blow-off and a P3 gauge running manual (just vacuum line to intake vacuum). Plugs have 45K Km on them.... as far as I know turbos & HPFP are original... Any thoughts or suggestions would be greatly appreciated.... 2000 Z3M - too many upgrades to mention ... lol

PWM is maxed out, looks like a boost leak.
4/2 is the proper setting for running a BEF.  Click on our banner to visit our website! Video of our Stage 2 LPFP upgrade installation.

Thats my concern.. going to rerun on Map2 and see if there's a difference... It has original turbos, HPFP, etc.... nothing been replaced yet. has 100K Miles currently. I might add that it has a really bad wastegate rattle. Just bought a vacuum hand pump with gauge so going to check that wastegates are holding boost...and
I will check for leaks. Thanks! 2000 Z3M - too many upgrades to mention ... lol

Another point I've noticed that may help point me in the right direction/test. When I loaded the new firmware, I noticed the FF/Wastegate adaptation had moved from initial 80 to like 170.... what is the ECU trying to do by adaption being so high? Is that indicative of a wastegate issue? Thanks, Bill 2000 Z3M - too many upgrades to mention ... lol

Max for FF is 150 and if there is a boost leak, it will max out eventually as it tries to adapt.

Thanks Steve. Given the amount of WG rattle and boost leak (although no codes), gong to test vacuum and see how the results are.
