with tune for meth the conservative tune should not be to far out if the variable pressure meth controller was working correctly. I say this only because hybrids meth pump just pushes lots of meth mix regardless of boost level. Hence you lean the secondary VE table to compensate for the extra fuel present. In that case you must have a meth mix never pure water only. If the meth/water mix is metered on a boost curve then I speculate that using a table switching mode would be unnecessary.
Not true boof.
We're talking about a safety for the meth not coming in at all.
Whether you have metered meth or not, you still have the boost and you don't want the tune going aggressive - either fueling or timing.
So IMO, even if you have metered meth, you would still switch tables, but fueling in the meth table shouldn't change much until you're pumping enough to affect it. Up top, they will be pumping in as much meth as me, so fueling would be similar. A meth failure at that point is just as dangerous as it is for me.
Having said that - when I'm seeing 70C intake temps even with low boost, I would be putting as much meth as required to bring that down. We don't really make boost unless we're trying because the bypass is open otherwise and just making lots of noise.
When you're talking about making power, it's timing that is the big factor and that's the thing you want to keep conservative when there's no meth.
I don't see how you can safely account for both scenarios without switching tables.
