i have a brand new S300 here in a customers car that i just strapped a turbo too. the car ran perfect before all this. the only thing changed was 780cc precision injectors and a resister box wired in. all wiring is correct , car starts with a stock ecu but will not idle cause of the injectors.
when you try and start the car with the S300 , it starts and dies right away , and when it dies , it primes again right away without turning the key back and on again. weird.
wont run even by giving it gas , sounds like its gonna backfire if you keep trying.
engine light stays on constant from the time you turn the key on , i have no codes yet.
it says the ecu is connected and you can upload a calibration , but you cant datalog it seems. click the lightening bolt , nothing reads.
the LED on the s300 is a steady red with a green flash every couple seconds or so.
also after it runs and stalls , you can hear the IACV buzzing.
is this a bad ecu socketing job or what? ive never seen anthing like this and am totally stumped at the moment.
S300 problem
tried the ecu in another car which also runs s300. same symptoms. i also tried the known working s300 ecu in the problem car , starts and runs perfectly. it is definitely a defective ecu. it was purchased brand new from xenocron.com. i advised him to get in touch with chris and he has his invoice so. hopefully they do something for him. i will definitely post his progress here. alot of money to pay for something that doesnt work when you get it , lol. but i realize shit happens and everyone makes mistakes.
