Im really interested in finding out alot of info about this because from what ive researched so far with the s2000 it is tuned very conservatively and just a good tune will show pretty descent increases. And if this harness that this shop supposedly has will work that would be awesome No, this is a standalone unit. You unplug your 3 harness’s from the factory ECU and plug them into the EMS. Load up your map and woo-laa all done. If you have someone else w/ the same mods ect… you could prob just snag their map if you have a wideband installed for safety. -Actually, you would unplug your 3 harness’s, plug the adapters into them, then plug in the EMS. What motor is in your car? F series? What AEM box are they recommending you to use with the conversion harness? --- _[View the full topic](https://forums.speedlife.net/t/aem-ems/190357)._
