F.A.S.T. efi
Has anyone replaced there factory ecm with one from F.A.S.T. I will be doing this swap shortly and was wondering if I will Have to retain the factory computer for any of the dash functions(speedo, tach,ect.) The car is a 92 and I want to keep the factory gauges. Any other advice anyone may have on this swap would be greatly appreciated.
