Rampage Fabrication & Design are proud to be EcuTek Master Tuners for the R35 GTR platform. We are able to calibrate your ECM & TCM both on our in house Dynocom 3500 hub dyno, or remotely.

If you don’t already have an EcuTek hardware kit you can purchase one through our online store here. Don’t hesitate to message us with any questions about ECM calibrating or for help planning your build.
