It does.

It's not absolutely necessary; the JBPerf P&H Board or the SymTech Labs PH Driver are optional upgraded fuel injector drivers. The standard fuel injector drivers work well too, but you have to configure the parameters for low impedance injectors in MegaTune or TunerStudio MS.

Originally posted by streetlightningi see some have used peak and hold on MS1, but was that b/c of the lack of resolution?

Many Megasquirt users use the P&H Board or PH Driver for a variety of reasons. The issue with MS-I and low impedance fuel injectors is complex, but it suffices to say that it does not affect your system.
