Ok guys, so I was stalking BMS post on testing the EWG (electronic wastegate) harness for N55 (335i) cars and as they came close to producing it in large scale, I spoke with Terry (BMS Owner) about EWG harness for N20 (328i, 320i) & if they are going straight to production but I was shocked when he said it's not in the test phase yet.. so I had a though I have to wait another 6 month to be produced so I can buy it until I got an email from him personally asking if I'm interested to be in first group for EWG testers as he wanted different test cars with JB4 only, JB4 & downpipe ect..
I promise I will try my best to send as much datalogs for analysis so EWG JB4 owners can have all the control & fun on their car.
