Note: We’re looking for a 2.3 Turbo car as a test mule for a variant of this ECU. If you’ve got an SVO Mustang, Merkur XR4Ti, or Thunderbird Turbo Coupe that we can use for R&D, please email email@example.com about your car. We’re in the Atlanta area and would need the test car for a few weeks.
Note: Although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the USB Stick can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately).
