When I get my heads decked [10:1 Compression Ratio], I think I may just run 89 octane and let the ECU curve the timing. That'* what will most likely happen, right guys? The ECU will compensate for the knock.. right?
i got my 94 ssei about 2 months ago, and have been running regular ever since. i think it'* like 87 octane maybe. i haven't noticed any problems or pinging/knocking. i should be using higher octane? like the manual or whatever says to use high octane?
