Hey guys,

I have a 2005 R53 with JCW exhaust and a JCW CAI. I might be looking to get the upgraded JCW fuel injectors soon (and obviously lots more down the road). So, I figure I need to remap my ECU. I talked to the parts department at my dealership, and they said that the JCW ECU tune is tied to the VIN number and can only be purchased when the kit is purchased as a whole. Is this true?

I obviously don't want to drop $6000 on a kit (especially since I already have half of it). I have read a few forums where people say you can't get the ECU without the kit, and I have read a few where people said the dealership did it for them. So, my question is, is there any way that I can get the JCW ECU tune without buying the kit? Have any of you done it?

Thanks!

Try another dealer. When the JCW 1st came out yes that was true. But now many dealers have done this for many owners.
