Ok I have got my PTU in the mail today and installed it into my Z. However when i tried to start my Z she still did not fire..... I strange part is when I went out to check the Ptu it was hot is this normal? I am worried it maybe my C.A.S. I just looked up how to check my ECU for codes. I ran out of time tonight to check them but i will tomarrow and post what is up... Any insight on this I would be so greatfull. Im am just ready to here her purrr after putting all this work in her. thanks again guy i know im in the right place.
