Swirl head race gas timing curves

[DodgeZ]

What kind of timing are you guys running with race gas? Force says his car didn't like much more timing than stock. Looks like even the MP tunes don't change the timing in +12psi of boost over what stock is at. I am working on my first swirl head race gas tune.

2.2L with swirl head.

Did you ever add more timing? I am running e85 also. Can you share your file?

I am searching for the same thing or at least somewhere to start out. I put on a ported head with de shrouded valves and modified quench so I know it's screaming for more timing. Next step is E85.

Tuned up to 20psi on E85. Ported swirl head on a 2.2L

No promise if it will work with your system.

That looks like it should be pretty close to what we set your's at, Kevin.

It was close to stock. I jacked it back up.

Found this while hunting e85 tuning.
"So, we know that E85 has a very high detonation resistance, one thing E85 does not have much tolerance for, is pre-ignition. This is where E85 starts to wander from exotic race fuels. E85 cannot withstand pre-ignition as well as it can detonation. I believe this is due to the fact that it actually burns much faster than gasoline(pump or race fuels), among other things. While it's very tolerant to lean mixtures(detonation), over-advanced ignition timing takes a toll quickly on E85. While E85 will take more ignition timing than pump gas overall, it will not allow a lot of ignition advance at peak VE, but will want more and more advance as RPMs rise, this ending up with much higher peak timing numbers. We'll get into that in the timing thread i will start."

Doesn't look like he ever started a timing thread

I meant the map tables were about the same lol,
