Somethings to improve while tuning a 6.4 Scat pack?

[tbrtuning]

The 0.85 area or a little leaner and not worrying about how low spark needs to be to eliminate knock worked out best for me. It seems weird to have to back off spark a good bit from the stock tune but it does respond well to it with the leaner mixtures.

My 2016 personal Scatpack runs at 12.0 AFR and peaks at around 18-19* timing. I have found minimal gains going leaner on customer cars, but not worth it to me.

I'm gonna agree with FlyinRyan on this one.
.82-.84 lambda here.

Im a .84-.86 Lambda on the Hemis. I set up an excel spread sheet for the math of different Fuel / Air ratios so now im plug and play. For you guys with a AFR gauge because that's what your used to the GM products, I suggest you buy a Lambda wideband so you can set up an error ratio easier. That's what I did to invest the dodge line calibrations. The trick is to find out how to increase the timing while maintaining your target Fuel / Air ratio. they don't seem to take as much timing as the GM LSx line we're used to. So, It will seem kind of weird till you research

recently did one on ethanol and it loved it

I've thought about doing that on my personal daily driver to see how it goes. If I could do flex fuel I would do it. What kind of timing did it like?

Quoted for truth.

it was pretty high with 25/26
