Quick question

Just want to double check a setting in the engine constants page, as I've not touched it in ages and have forgotton :( when calculating the req fuel number, is the AFR target 14 or 14.7?

thanks!

Of course, but the req fuel has to be calculated with the stoich value.
Fuel map should compensate when under boost.

That's right, for ethanol it would be like ~9 i suppose. The 14.7 lets MS know you're using gasoline.
