Not a lot of update but I thought that this may be a significant one...
I've sourced a JDM Honda PCD obd2b ECU. This is the closest matching OEM ECU for the H23A VTEC engine aside from the original (which I can't remember the code) Auto ECU...
I'm going to try the PCD ECU and see if it does a good job running the H23A VTEC. The only thing lacking is that the PCD does not have IAB control. Worse comes to worse, if the PCD ECU works well, I might just wire up the IAB and link it to VTEC so whenever you are in VTEC, the IAB will open up.
This does involve re-installing the secondary O2 sensor and uninstalling the AEM Wideband and re-installing the primary O2. I'll update on how this progresses. If all goes well, I'm going to try to pass emissions with the PCD ECU.
BTW, the PCD ECU does NOT have an immobilizer. I see where the space it for the immobilizer board, but it's not installed.
