i have s300 and a boosted gsr i dropped second hit boost and the check engine light came on and the car died... i looked into it and it was a blow ecu fuse so i replaced it and as soon as i turned the key to on it blew the new fuse so i put a 20 amp in reloaded my base map and its good to go... all the engine grounds are fine so the question is what could possibly cause this... also after i got it running i was datalogging with my laptop and it stopped data logging and the light on the ecu went to straight red. it u hit the datalog button again it starts data logging but the light stays solid red... i unpluged the laptop and turned the car off and back on and the light is back to green. any ideas?

 

anyone?
