C16 fuel on motec

[O.alsuw1]

Hello,
I have a turbo charged that runs on pump gas with 98 ron fuel and i am planning to mix the fuel with c16 fuel, from my knowledge pump gas has stoicmetric value of 14.7 and c16 is 14.77.
Currently my engine runs on 1.4 boost and has igntion timing of 15 degrees, my question is how much timing could i increase if i put 50% c16 and 50% pump gas also, can i use c16 for daily use and how can i tune it? Should i make 2 maps? 1 for if i am only going to use pump gas and the other for when using the mixture? And what afr should i aim for? Currently runing on 11.5
Thanks

To be fair...by virtue of you asking all those questions....you should really take the car to a competent tuner and let them sort it.

Modern oxygenated pump fuels are closer to 14.0:1, all gasolines are a blend and will have differing stoich values.
