MS3Pro ULTIMATE Pinout Glossy Card
How big is the ECU?
The MS3Pro measures approximately 8.5″ long (including the mounting ears), 4-5/8″ wide, and 2.5″ tall including the mating connectors. Not including the connectors, the case itself is 1.5″ high.
Where is this product manufactured?
This product is manufactured in Gainesville, Georgia, USA.
What is the warranty on the MS3Pro ULTIMATE?
It carries a one year warranty against manufacturing defects.
How watertight is the box?
The case uses an o-ring seal and sealed connectors to ensure it is completely splashproof, and will keep water out if completely immersed up to a few inches for a few minutes (which normally shouldn’t happen, right?). If you need further water submersion resistance that can be accomplished with a small bead of silicone just inside/outside of the o-ring.
Can I run big low impedance fuel injectors with Ultimate?
Does this support Drive by Wire? If not, which Megasquirt system does?

QDoes this support Drive by Wire? If not, which Megasquirt system does?
Asked by Ian

We currently do not have a drive by wire control device. It is something we are looking into, but do not have a firm release date. Particularly since this is not the sort of thing one would want to push up the release to fit a timeline if the debugging isn't complete.
Can the the MS3Pro ULTIMATE control a GM 4l60E transmission together with an LS 24x engine ?

QCan the the MS3Pro ULTIMATE control a GM 4l60E transmission together with an LS 24x engine ?
Asked by Mark Bhikarry

You will need to add an external MicroSquirt to control the transmission. The two devices link up over CAN so you only need a single point of tuning.
