Vafc is for vtec but since you don't have it it won't control it or you can pick up an safc either ons is fine.

A 90 integra is obd0 all the software for obd0 ecus suck and are outdated. That's why hondata aem Crome etc are only for obd1 ecus. You would spend $150 on a conversion harness, $180 on ecu, $100 on distributor then have to install it all before you ever even got tuned.

IMO an ls engine with your mods it's a waste of money.

Pick up a safc or vafc and just have it touched up , ls engines aren't going to make a ton of power with timing or tuning and your mods.

If you plan on getting cams, better header etc in the future you may want to thunk about going obd1 but I susspect you're just looking for a little power gain.
