S5 rotors in a S4 13bt/ S4 chassis
So with the higher comp. Will I need to up the fuel given to the engine. Or would the ecu some how deal with it?
This would be using an Rtek 2.x.
I would think, Higher comp would require a bit more fuel to keep it from detonating. so maybe upping the stock fuel maps up a percentage would do it? If so, anyone have an equation to determine the amount needed to add?
Has anyone compared S4 and S5 stock maps?

Unless you are running on the edge I doubt you would have to make much if any tuning adjustments. What do your air/fuels look like right now anyway? If they're in the 11's your probably fine, if your floating up around the 12.5 mark then you probably want to add more fuel to the mix espicially if your running more than stock boost.

We haven't built the motor yet.
We may just swap out the 2 S5 rotors for some S4's just for easy of initial installation.
My friend is going streetport and we were initially going to do BNR stage 2 but we're thinking he's going to run out of steam and he may do a t04. So Rtek may not even be in the ranges now.
