Just want to point out when I had my SHO with the LME 4+X tune, I used ACES IV, I still had audible knock under moderate partial throttle runs. Obviously Torque Pro reflected this. Ran an E85 blend next tank, and didn't experience any of that. I stopped using ACES IV, and that's just my personal experience.
This is why I have urged caution for those wanting to run a 100 octane race tune. (does anybody even know how to quantify that?) I think there is another member here along with AGF that had an OAR drop. I think DX runs a hot tune on his SHO but OAR never hit -1 on it.
"Octane" with a given fuel will be consistent from vehicle to vehicle, "octane effect" will not IMHO so I strongly urge caution and I think the best path is using a tuner along with logs and turning up the wick slowly.
Personally, I don't use ACES for the "octane effect", I use corn. (Brian is not a fan) I do use ACES for the lubricity left behind for the reduction in bore wear and its ability to reduce preignition fighting hot spots which I believe is valid and I think I've pinned down the ingredients. Also I have so much corn in the tank that there is no way I could add anything to testing. I'd have to piss in the gas tank after an all night bender to see a oar drop which is currently maxed at -1.15.
I have done some research into trade secrets laws, particularly with regard to MSDS. It seems equitable to all parties so I am comfortable with having discussion about it if AGF is OK with me staying in the thread.
