Problem with S300 uploading

Xenocron should be able to assist you with this, you will probably have to ship it to them.

I’m having a similar problem but my old s300 was working in my ecu but my new v3 isn’t uploading or data logging
Serial:54660
P28 ecu
In a 96 civic ek lsv turbo
I tried to reinstall drivers but that did nothing when I click upload it flashes bright red but then goes back to flashing a dim red and it doesn’t upload any maps

Are you sure it is seated on the pins properly?

Have the capacitors been replaced in the ECU?
