I have a 75 Chev pickup that has a 502 crate engine, ZZ502 that has fast fuel injection, it is a version 1.02, just wondering if anyone knows somewhere in Norfolk or Brant areas that knows or can service them, nothing seriously wrong but was told it might be time to get it looked at and possibly clean the throttle body, any help or anyone have any information please let me know, thanks.
There is several types of fuel Injection by FAST. Since it is an older version at 1.02, is it the XFI, or EZ-EFI?
They are on version 2.0x for both of them now, which is different hardware. There is a free firmware update for your older version, and you can download the tuning software for free.
Not sure what it is, is there anyway of telling for sure if its XFI or RZ-EFI, sure appreciate the help and if you can tell me what to look for in telling what it is that would be great too, thanks.
Found out a little more, I contacted Fast and it was purchased in around 2005, I was told it is an older version of XFI, there is a download to update but its over and above what I would want to try myself, the download is called C-comWPsoftware for greybox fast ecu. That's what I have found out so far, if you have any more info let me know, thanks RacerRick for your help.
