The only US fuel that would work is the low ash 94 octane sunoco available in some parts of the country. Or, MS100 or MS103 which is sold at the pump. Other then that, Running these motors on US fuel is not a good idea. I had the luxury of datalogging a V7 JDM STI all stock on japanese fuel and even 93 octane wont produce the results. I have tuned and datalogged dozens and dozens of V7 and V8 JDM motors on 93. Dont do it.

At a minimimum, You will be at reduced power and at worst case, you pop the motor. I have seen about a dozen toasted V7's and V8s in the last 10 years from shenagans like that.

And there is no reason to really. Since my maps where ripped off and posted as someone elses work, you can download some of them for free now.
