Default F10 M5 JB4 Water Meth - 09-18-2021, 10:17 AM

Hi all.

I have a 2016 F10 M5 Comp, de catted, Akrapovic, Eventuri, Project Gamma chargecoolers, gearbox map, 22 PSI engine map, JB4 for datalogging/gauge info/boost control.

I'm happy with the setup but would like to add water meth injection.

I'm not so fussed about increasing boost much, more interested in keeping IAT's cool as after a couple of pulls I'm seeing 50*c (120*f) IATs and can feel the car starting to hold back. And my Dragy times confirm this.

Can anyone advise settings and water to meth ratios?

Thanks in advance!

Most run boost juice which is a 50/50 mix.
