Running ID725 primaries and ID2000 secondaries. Saw the MS3-Pro has an optional P&H driver - am I going to need it for the 2000s?

Thanks,
Luke

Not sure specifically about the Pro, but I'm running ID2000s x4 with MS3X with no additional mods. Just make sure you enter the dead times correctly or you'll be chasing your tail trying to tune low pulsewidths.

Wow, that's a lot of injector. Have you ever come close to maxing them out? Curious about how they behave at the limit with just the MS driving it. And thanks for the tip on the dead times, I'll keep that in mind

you dont need the p&h board the p&h boards are for low ohms injectors

On 20-21 psi and an EFR 9180, I see over 50% duty cycle on pump gas + ~1000cc/min of water injection. I kinda went overkill because I had considered using ethanol, but am happy i did.

Initially I was unhappy with how the injectors behaved at idle and high vacuum cruise, but I'm pretty confident that it's actually overlap from my large street port wreaking havoc. I idle at 1000 and low 12:1 afrs. Any lower than 1000 and it gets brappy and only runs well rich. Adding timing helped some with the high vacuum part throttle drivability.
