MS3Pro Sequential Electronic Fuel Injection and Ignition

MS3Pro ULTIMATE with Universal Wire Harness
MS3Pro ULTIMATE with Universal Wire Harness

The MS3Pro is our top of the line engine management system. It packs up to 12 fuel channels and 8 ignition channels into a single ruggedized enclosure. This one can run 4 channels of continuously variable valve timing, progressive nitrous control, and more! We’ve taken the optional features on the MS3X (knock control and the real time clock), and made them standard, then put the unit into a splash-proof case with beefy AMPSEAL connectors. We have two versions available – the MS3Pro EVO and the MS3Pro Ultimate. The Ultimate adds extra I/O channels and peak and hold injector drivers. Click here for more details about the MS3Pro.


MegaSquirt 3 / MS3X Sequential Electronic Fuel Injection and Ignition System

You can’t get more bang for your buck.  The MegaSquirt 3 with MS3X is an incredibly featured packed and highly capable Engine Management System which will control most engines Electronic Fuel Injection and Ignition Systems as well as anything else you’ll find on the market even at 2-5x the price!

With 8 channels of sequential fuel injection, a matching 8 channels of sequential ignition control, and a large number of additional outputs to control everything from Variable Valve Timing (VVT) to multiple stages of progressively controlled Nitrous Oxide, to closed loop turbo boost control and much more, you can do just about anything you’d ever need to do on a race engine with with ECU.


OK, tell me more about all of the Pre-Assembled Wire-In MegaSquirt System options!

Above we’ve already told you about the ‘flagship’ MS3/MS3X systems we offer.  Here is a quick comparison between MS2 and MS3.

MegaSquirt-II MegaSquirt-III (with MS3X)
Firmware version used when making this chart MS2/Extra 3.2.1 1.0.5a
Fuel control 2 channels, bank to bank
Can be expanded to 4 channel sequential, but it’s not easy.  Recommend MS3/MS3X for that.
8 channels, fully sequential.
An additional two channels can be used for a second stage.  (8 sequential plus 2 batch staged)
Fuel precision 0.6 microseconds 0.6 microseconds
Ignition control Up to 6 channels available Up to 8 channels available
Idle control On / off, PWM, stepper On/ off, PWM, stepper
Communication RS232 serial USB and RS232 serial built in
Data logging Through laptop Internal SD Memory Card for on-track recording without a laptop, or optionally datalogging through laptop is also supported.

Note these are just the highlights– there are other things to consider such as the fact that MS3/MS3X have a large number of inputs and outputs that can be used for datalogging extra parameters and controlling more on your engine that the MS2 either does not support, or has fewer options to use.

For a very complete feature-by-feature comparison of these different product options, make sure to take a quick look at this page on the MSExtra.com site with a feature comparison chart that goes into great detail!

Then, we have accessories; here is a rundown of the ones you may want to consider.

MicroSquirt

Although this one has more in common with the pro lineup in that you don’t build it or need to open up the case, its $339 price tag (and that includes the wiring harness) makes it VERY attractive for low budget wire-in installations too.  This small weathertight ECU was originally designed for powersports applications – PWC Watercraft, motorcycles, karts, etc.  But its small size and rugged construction also makes it popular with people who want an ECU that’s easy to put in an inconspicuous location, like street rodders, or racers who want an ECU that will stand up to harsh use, such as road racing or dune buggies/mud crawlers/etc.  This unit has two fuel outputs and two spark outputs allowing sequential fuel and ignition on a two-cylinder, such as a V-Twin, or semi-sequential fueling for a 4cyl engine, or batch fuel for 4-8 cylinders or more.  A PWM output for idle or boost control is included, and two on/off outputs for controlling things like fans or anything else you can dream up that you’d like the ECU to switch on/off in different conditions.  It’s possible to reconfigure it to use these extra on/off outputs as spark outputs as well allowing for sequential ignition on up to 4cyl if you purpose those outputs to the ignition system.  Although most users of this ECU tehnd to be running engines with somewhere from one to four cylinders, it can be, and has been, used on V8 applications for a low cost simple fuel injection and ignition controller with high durability and a tiny footprint.
