software up date issue
I have a sbf 302 with a go street 400, it was RUNNING GREAT but my hand held controller buttons quit working, so I went to fitech to get a new one, the tech said my hand held was b/o and he gave me a new one with new verison software as my old hand held was out dated. When I got home I called fitech and they helped me step by step install the new hex software file and v8 software file. When I started the car it fired right up, but it started to back fire out the exhaust and gets worse with more throttle. When I first installed the fitech system 1 year ago, I just selected the v8 software file, fired it up, no problems. I sent a data log to fitech and they said everything looked good. Is there something Iam missing?
Double check your initial settings.
