I have a 93 Integra RS, and this guy has a 93 Integra GSR. Hes selling his Hondata S100 thats already install into his ECU, and im gonna buy it. Are our ECU's the same?? cause a buddy told me, that he just has a VTEC wiring harness that plugs into his ECu and mine is left open, so it would be easier to swap ECU than him getting someone to take out his Hondata Chip and me having to get someone else ot put it into mine.

 

The ecus are different.
You CAN run a vtec ecu on a non vtec setup. But the ecu MUST BE PROGRAMMED with a non vtec basemap.
