    Default Holley Commander 950 Software/Firmware Versions

    Hello. After a bit of work, I have the Holley Commander 950 software running in an emulated instance on Win7. It required a USB-To-Serial adapter & software, but I got it to work and I'm connected to the ECU. When I pull the data I see that I'm on version 3.07 of the Software, and 3.0 of the Firmware. Is that the latest? I did notice I'm running a narrowband O2 sensor, and purchased the upgrade to the Bosch wideband, but it's back ordered. Regards, Michael

    The latest C950 EFI software version is 3.0.7, and the ECU firmware is 3.6.

    Danny, are there any release notes on the firmware revisions? I understand I would need to send the ECU in, just curious on the benefits of the subsequent revisions? Thanks, Michael

    I'm not aware of any such document on Holley's website. So you'll have to contact Holley Tech Service (LINK).
