J12 has nothing there

Have you tried your s300/ecu in a known working ECU/vehicle?

I unfortunately don’t know of anyone that has a car for me to check with is ther anything I can do to check it

I swapped the entire main harness for one with no splices I can connect to the Bluetooth but it’s saying my ignition is off and I still can’t upload or view in real time

Did the person that did the work on the ECU test it to make sure it was working?

They just put the new stuff in the ecu I’ve seen socketed ecu for 230 on eBay idk if it would be best to buy one or just send this one off for repair

Have you verified that the S300 is seated properly on the pins?

We don't repair ECUs, so if the ECU is the problem, You will need to replace it.

I have taken it out and re seated it could the s300 board itself have an issue I still can’t upload anything or view in real time on the app I can connect with Bluetooth but it says the ignition is off so I can’t do anything else

Quick question if the socket tester is showing all green shouldn’t that mean the s300 should post up I emailed support they told me to put new capictors because it was showing the ecu wasn’t powering up but I’m on my 3rd ecu now

You need to ask this via email if you are in contact that way.
