So what you have is just a JDM 1.5 SOHC VTEC. Nothing unusual. No LSVTEC engine there.
It's Honda's smallest VTEC engine. (Similar to the US spec VX engine)
You can get a OBD2-1 adapter, and use a P08 ecu stock, or have it chipped.
Hondata is not going to be able to help you on this one.
I know, I know.... Why not?
The JDM 1.5l VTEC engine is missing a few parts that Hondata looks for.
1- The ECU does not have a barometric sensor
2- The ECU does not look for a VTEC oil pressure switch
3- The ECU does not look for a Knock sensor.
Although #3 doesn't matter, 1 & 2 do.
HTH's.
