As a great supplement to our turbo kits, we commissioned these hand made in the USA patch adapter wiring harnesses to plug in to the ECU Masters DET3 (Digital Engine Tuner 3) piggyback system, as well as the factory JDM 95-97 JZS155 hardtop Crown ECU and harness.
We're huge fans of the Crown at XAT, having brought over around a dozen by now. This terrific platform yearns for a turbo setup! Since a standalone ECU is not ideal for everyone or every build, we now offer this alternative that keeps all factory functions and drivability of your 2JZ VVTi Crown, but lets you fine tune further and swap out injectors for when youre ready for more power!
We strongly recommend going this route in conjunction with our turbo kit. You will be limited to wastegate pressure and low boost on the kit, unless you upgrade injectors/fuel system and go with a tunable ECU.
