You have to fool every sensor to make a difference, the most important one being the o2. You should look into moving the temp sensor to a colder area of the engine bay, or moving the air intake to a warmer area. that way your computer can still react in its specs and compensate without massive detonation/ping. I messed up and made a warm air intake and my old 1995 ecu couldnt change the timing enough so i had to go up to 91 octane until i changed more items.
