Hello.
I have recently become a VEMS owner. A bmw M20 with ITB and VEMS v3.3 controller.
The cabeling for the wideband sensor has been damaged by heat and i plan to replace it. Would like to upgrade to LSU4.9.
Do i need to make any changes to the hardware other than follow the pinout instructions?
Can my v3.3 handle LSU4.9?
Do i have to add a resistor?
Anyone with any experience how big the difference is between 4.2 and 4.9?
Since im running ITB's im running alpha-N tuning. Quick lambda response is important. But i have very limited experience, and the current lambda has been unreliable due to heat damage to the connector.
Happy for any feed back!
