^^^ thanks for that.
It depnds on the application -- richer (say mid 11's to mid 12's) is usally a bit better for FI (especially if nonintercooled or intercooling isn't optimal or only lower octane fuels are available...), but really it all has to determined empirically on the dyno.
Just took a gander ant the UpRev site -- looks like they offer full datalogging (cipher) and have full control over all the maps... but I couldn't find confirmation that they can tune VVEL.
Is it really true that even the uprev software can't tune VVEL on our car??? That seems like a huge tuning limitation if true
