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.

Try the ECU in a different car first, if it does the same thing try a different ecu. This will help you determine where the problem lies.

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.
