    Question about tunes

    I can only see the following tunes on MyMaptuner for my spark. Is this the same list everyone else sees? Also, which of these is the 402 tune I hear about?- I don't see it on my list

    Does anyone know a summary of these?

    The 402 has been renamed ... Down load them and keep the one that feels the best ...

    i have tuned many Sparks and the latest don't show the 402 ..

    Thanks Slasher.

    Anyone know of an alternative to using E85 for the E85 tunes? Can I run higher octane instead? I can't find E85 in my area.

    No there is no alternative for e85. E85 has less stored energy per gallon the gasoline. You could run the race gas tune with higher octane race fuel
