BMW M50 B25 Turbo
Early 2018 Purchased a Vems (TODO: exact serialnr) ==> 15130 from Pieter, Vems V3 with lsu4.9, Sensors, and Wiring Harness and relays etc.
A Friend of me mounted everything inside the car and connected it like it is shown on the Vems papers (electrician) and wired up already alot Vems ecus in several cars.
In my case its a 1985 BMW E30 with a m50b25 Turbo Engine... (just for info)
April 2018 Pieter came to his Garage for the First Startup and Calibrate etc. Everything worked without any issues.
TODO:
- vemslog of running engine --> From that day i have none
- or at least vemscfg of working setup
Dyno Mapping was done 06/2018 and also worked pretty good with the ecu.
I Drove then for around 5000km with this ecu without any Problems.

Problems start
2019 Januar 2019 I changed the Cam setting from the Engine and built in a Water Meth injection.
Dyno Mapping was done also in Januar. worked again good so far. Misfiring at End of the day above 1.8 Bar Boost.
TODO:
- wiring of the changes --> Nothing changed on the wiring. Its an extern Controller from the WMI
- vemslog of running engine --> https://www.file-upload.net/download-13862742/v3.3_u015130-2019.02.23-14.07.36.vemslog.html
- or at least vemscfg of working setup
Summary:
- worked fine
- After changes => problems.
- Let's see the exact HW, wiring and config changes, including the before/after state so we can review, reproduce and give hints.
- this is the only professional way to do things: collect the relevant info in a way it is possible to review, edit, add, extend, ...
