H22a euro R obd1 or PCD ??
Unless it's modified, I'd suggest running the OEM ECU and wiring in the IAB if you're using that manifold
If you aren't using the IAB manifold, a chipped P28 with a proper tune will run great. Alternatively you can install the IAB circuit in the P28 and wire in a relay.
But an H series engine will never run right on a basemapped P28, especially if it's modified, so it needs to be tuned if that's the route you choose.
