OBDII to OBDI conversion

[Prelude707]

Hey guys I was interested in converting my OBDII ECU from my 2k Prelude into an OBDI so my mods aren't being detuned every couple hundred miles. As far as I understand, all I need to do this is a OBDI P13 and a OBDII-OBDI harness. Is this correct? What about the different fuel maps and stuff.

Also I am considered installing a small shot of nitrious into my car. Somewhere along the lines of a 50 or 60 shot. I was gonna go with a Zex wet kit. My Lude has got 47K on it with intake, exhaust, pulleys, headers, fuel rail, fuel pressure regulator, ACT clutch, a A/F ratio and fuel pressure gauges. My engine should be able to handle it right?

To be specific, you need the OBDIIb-OBDI harness.

But as far as fuel maps go, the p13 has the correct fuel maps for your h22.
