#1 of 1 GMC 5.3L LY5 conversion to 5.3L LMG E85 by jkach Aug 28, 2008 (8:55 am)
I have asked several GMC service managers and can't get the same answer. (some say its a reprogram of the computer-gas cap- and decal, others say its a replacement of the fuel rails-fuel pump- and reprogram - and still others advise that it can't be done). I have spent several hours on the phone with GMC tech and can't get an answer / they just refer you back to the dealer’s service manager. So, my question, I am in the process of purchasing a new 2008 GMC with a 5.3L LY5 motor. What is involved in having GMC convert the 5.3L LY5 motor to a 5.3L LMT E85 ??
