Oh, I do a little here and there.
So, I'm running an OBD1 b16a swap in my 99 sedan. The problem is I have a check engine light on throwing code 41: heated oxygen sensor. Now, the ecu I'm running came from a del sol vtec and it's not JDM so..could that be why I'm throwing this code and if so, how do I fix it?

Reason I ask is because before I got my hands on this USDM P30 I was running a P28 with a B18C1 basemap but always took it easy due to the differences such as air/fuel ratios.

This may not be my only trouble code as I do believe the USDM b16a came with a knock sensor that my JDM one doesn't have? I am not too sure. Any help is appreciated!

By the way, for some reason, when I floor it it doesn't want to really accelerate past 100 mph?
