Hi,

So currently just did a b18c7 swap on a EM1 with stock b18c7 ecu ( Immobilizer removed)

Used a Rywire harness converter from OBD2B to OBD2A as the B18c7 is OBD2A

Current issue is my Tacho does not work (RPM) and getting a engine light for the IACV.

Can anyone point me in the right direction? I think for the tacho i just have to hook the cluster to the ICM.

But no idea about the IACV
