JB4 installed and now fault codes
Anybody install the JB4 in a Z4 35is and not have fault code issues? I just installed the JB4 (Map2) and keep getting error codes for O2 sensors and fuel pump. Installed new 02 sensors but keeps giving same codes. Tried to shut off JB4 while installed (map 0) but same codes still come up. Once I removed chip, all good back to normal.
