Car running great, laptop connects as usual no problems.
the other night i changed fuel pump to a DW300 by Deashwerks and also added a FuelLabs 515 fuel pressure regulator.
After install of those parts, car ran okay but then blew main relay. No fuses popped Only the main relay. So I bypassed it to get back home 10mins away.
Next morning car starts up fine with a new relay, I go to take it out to do some tuning and the tunerstudio goes offline with the car running.

(It was even in the middle of a datalog but the log doesn't show any clues to why it happened from sensor data. Everything normal up until Only shows in the log that it logged off and back on and then off again and that was it)

I can't get tuner studio to reconnect so I go back home.


Key in, fuel pump primes, car starts up fine (Only half-tuned though). But I cannot get the laptop to connect for the life of me. And I usually never have problems with it on this laptop!

All help is appreciated! Thank you for your time in advance!!

 

Solved. It was literally my Serial to USB adapter that broke.
