Hey guys, just after some advice with E10 tuning a vyss commodore with cam/heads etc....With PE is .40-.50 deeper in AFR a good starting point ...say with unleaded 98 octane it made peak power at 12.71 afr 0.86-.0.87 LAMBDA... so for a SAFE PE I have changed it to 12.29afr 0.86-0.87 LAMBDA......and with timing I have added a extra 2* SO with E10 what timing/PE changes have you guys done and seen? I know once it hits the dyno I will see...cheers Bret
