For some odd reason my ecu is blinking a red light dont know why... I tries putting on a stock b16 ecu nd jumped my car nd it finally turned on, as soonas i took the jumper cables off my car shut down...anybody know what can be the problem?

 

Battery or alternator....the red light mean a code so you need to count it and check tht out..

 

Well the thing is i have hondata s300, nd when i plugged in my boys ecu and jumped it it went on, soon as i took cables off car shut off... Would be nice if it was obd1 but its obd2 nd i really dont know what it can be, u think alternator might be the problem

 

Obd1 or obd2 same diagnostics
