Hi all,
I am manual converting a RA3 Odyssey with a F23a. The only manual ECU available is from a CG5 Accord with a F23a.
On the RA3 the o2 sensor is very close to the cat. On the CG5 the o2 sensor is alot closer to the head where two cylinders merge.
I am wondering if it is ok to leave the o2 in its current position near the cat, or if i should move it to match the ECU, being near the head.
See pic.
Obviously it would be easier to leave it as is.
