Now shipping: the MS3Pro Ultimate!

Order the MS3 Pro Ultimate here
The MS3Pro Ultimate is a new ECU that pushes the MS3Pro design as far as it will go, with more inputs and outputs and the features customers with big horsepower engines have demanded. Here's a short list of what we added to the hardware:
- Peak and hold drivers (software selectable 4/1 or 8/2)
- 5 more analog inputs
- Onboard 4 bar MAP and barometric pressure sensor connectors
- 2 more VR conditioners - for Coyote cam sensors, vehicle speed sensors, and more
- 7 more switched inputs
- 4 more on/off or PWM outputs
- Status indicator lights
And there's a new firmware upgrade out to support the MS3Pro Ultimate which you can also load to any current MS3Pro. The new firmware brings several new features:
- CO2 dome pressure boost control
- Four wheel traction control
- More records in SD card data logs
This new version of the MS3Pro sells for $1499 with an 8' flying lead harness. For those who don't need all the extra I/O, we still have the entry leave MS3Pro available too.
Very cool. Almost makes me wish I didn't just buy a new MS3pro and JBPerf board. Do the extra PWM outputs run on a different timer, or is it still split to the 2 PWM frequencies with a max of 250 Hz?
It includes a USB and a serial cable.
Still has the same maximum of 2 high frequencies for the high to medium frequency range. The JBPerf board (or a MicroSquirt with IO Box firmware) does add more possible frequencies since that board generates frequencies with its own hardware timer.

Wow Shifti, that collector looks awesome! What sort of difference do you think you'll see in the real world between the Garret and what you made? Faster spool due to higher velocity from smaller diameter?

Got a trailer to go with my new truck. Couple bits of maintenance needed, but otherwise good to go. Tow setup ready to go. I should start my miata, its been a few months...
Welcome to the forum.
You should definitely install the megasquirt and learn to tune prior to adding the turbo.The level of difficulty only goes up when you have so many new parts in play at the same time.
