In the past when doing a K-Swap you either had to purchase a Type R ECU or a Hondata Kpro. Now with the release of the new Immobilizer Removal Unit, you can use your bone STOCK 02-04 ECU. Simply connect the 4 wires as outlined in the install guide and you are ready to rock. In addition to bypassing the Immobilizer, it also disables the multiplex code P0600 so that you can run an error free ecu. The unit works with the following ECU's so make sure to double check the code on the side of your ECU before purchasing: PLM, PLR, PND, PNF, PRA, PRB, and PPA.
