Update wideband LSU4.2 to LSU4.9
« on: June 05, 2017, 03:00:00 am »
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!

one resistor is needed, 4.9 has different connector and pinout.
