not yet... retailer have use a small tester(photo can find on hondata website) to test my Ecu and show it all green lights (motherboard and s300 chips)
Oh, btw my ecu have installed odb2 convertor too(the gery part)

How exactly has this been wired?
I follow the ek9 ecu idle setting on the below photo.( connector B)
Also I have 100% confirm my hondata s300 is work normally.(It checked by Hong Kong hondata retailer)
After that I have tried disable/enable o2 or idle sensor for start up but just not working ...

Got a brand new S300 v3 installed in a P28, installed SManager, updated the firmware and registered the ECU to Hondata. Everything looked good and I was able to upload the base ITR map to the ECU. When I start the car it would fire up and die quickly in less than half a second. Any other attempts ...
