I have a sc and I'm just looking at various e85 and even 93 octane spark maps. It looks like a lot of the turbo maps I've seen on 93 are quite aggressive compared to the few supercharger spark maps I've found on here. Is there. Relation to being able to run more timing on a turbo application? If so does it maybe have to do with iat or the way power is delivered with some superchargers? I'd like to hear someone that has experience with both. TIA.

 

Yes, very different in numerous ways.

 

@18psi would you care to explain or maybe have a thread to link me where i can learn about this?

 

Yes.

 

The way the boost builds impacts it greatly, think about superchargers are more "linear" in the way they make boost and the table would reflect that, turbos build boost later but more rapidly and the table would reflect pulling timing as the boost ramps up
