First time s300 user

Hey Spunkster, did some work cleaning up the ECU while I wait for the new one I ordered to come. I hooked up the s300 again just on a whim, and it started data logging for a minute and when I started the car it sounded normal (previously when it was working it was super loud). I had both green lights on the ECU as well as the red one. The car ran for about a minute and then it changed how it sounded and the car started to die so I switched it off. When I turn on the ignition, I can hear the relays for the AC and what not next to the battery in the engine compartment are buzzing. The car also doesn't want to start now. Didn't change anything in the tune just had it running a base map.

Any idea? Maybe internal on the ECU so that when it heats up something stops making contact? New ECU is coming during the week, I will try that out and let you know, but any thoughts are appreciated.

Thanks

Here is the pictures from when the s300 was working. I was getting feedback from the 3 lights at that time as well

It probably has damaged vias and once you socket a different ECU it will work as it should.
