From what I've briefly gleaned, from not yet reading the instruction manual (as you do), it controls up to 8 injectors based on boost/rpm.
I have an Apexi PFC ecu and 800cc injectors so fuelling's not an issue. I was wondering if it would be worth using it to squirt in a bit of methanol at WOT, just to cool things a little, and maybe extract a little more

Anyone have experience or opinions please?
