The MS3-Pro was recently released by DIYAutoTune.

http://www.diyautotune.com/ms3-pro.html
 
This is a more professional version of the MS3 technology that is designed for professional installers to have them on the shelf to install into any vehicle required without building circuits on PCBs or removing/adding components. Retail pricing for both the ECU and wiring harness is under $1,200.
 
The MS3-Pro is waterproof, as shown by their demonstration of the ECU working from inside a fish tank...

   

Here is a complete list of the MS3-Pro's features:

Hardware features:

• Freescale MC9S12X 16 bit, 50 MHz asymmetrical dual core processor
• 10 saturated injector drivers
• 8 logic level ignition outputs
• 3 high current (5 amp) general purpose outputs - 2 can be reconfigured as additional injector drivers
• 3 medium current (3 amp), high frequency general purpose outputs
• All unused injector and ignition outputs can be used as spare on/off or other outputs.  This ECU has a LOT of I/O!
• 1 stepper H-bridge driver
• Camshaft and crankshaft differential inputs - supports VR, Hall effect, and optical input
• 12 volt tach output
• Fuel pump output
• 8 analog inputs (5 dedicated sensor inputs, 3 spare/general purpose)
• 4 spare digital on/off inputs
• 3 spare digital frequency inputs
• 2 knock sensor inputs
• RS232, USB 2.0, and CAN communication
• Onboard 8 gigabyte SD card for internal data logging
• Internal ECU temperature sensor
• Real time clock
• Temperature range: -30 to +80 degrees C (-40 to +85 without battery for real time clock)

Software features:

• Supports speed density, alpha-N (TPS based), or MAF based fuel and spark tables
• 1 microsecond injector pulse width resolution
• Tables for nonlinear injector behavior at small pulse widths
• Allows blending multiple load types, including specialized mode for independent throttle bodies
• Supports a wide variety of OEM cam and crank position sensors
• Individual cylinder trim tables for fuel and ignition
• Accelerator pump or model based acceleration enrichment
• Closed or open loop idle speed control
• Closed or open loop boost control with two separate wastegate outputs, and gear or speed based tuning options
• On/off or closed loop continuously variable valve timing (VVT) control - supports up to 4 channels
• On/off or progressive nitrous control
• Traction control by VSS or RPM
• Rally anti-lag with rotational idle
• Rotary support - can run up to 4 rotor engines with separate leading and trailing spark tables
• Staged injection
• Table switching
• 16 x 16 fuel and spark tables - can be reconfigured to function as 30 x 16 or 16 x 30 by switching tables based on RPM or load
• 2 or 3 step rev limiter (launch control) with no-lift shifting
• Wideband AFR target tables
• Flex fuel sensor input for easy switching between gasoline and E85 - can automatically change fuel, ignition, and boost maps based on ethanol content of gasoline
• Knock control with adjustable crank angle windowing can adjust sensitivity based on RPM or which cylinder is firing
• Allows repurposing injector or ignition outputs as general purpose outputs, or high current outputs as injector drivers for 12 cylinder sequential applications
• Real time barometric correction (external sensor required)
• A/C and cooling fan control with idle compensation
• Safety shutdown based on AFR or EGT input
• Sequential shift cut and air shifter control
• Diagnostics to detect and ignore failing sensors - can even automatically switch from speed density to alpha-N in the event of a MAP sensor failure

 
The main reason I want to advertise this on here is, the MS3-PRO can handle 4 Variable Cams, so it looks like we now have a relatively cheap option for....
THE 2GR-FE!
This means no more stupid sensor errors, nor more stupid immobilisers and no more stupid Drive By Wire (must fit a different throttle body and TPS, but this is easy).

Another awesome step forward for the DIY EFI crowd.

The MS3-Pro Module
http://www.diyautotune.co.ms3pro_module/index.html

 
This is like the older MicroSquirt module that gives you all the fancy features from the MegaSquirt technology onto a single brainboard, then you can build your own plug and play board to suit your motor and then drop the MS3Pro module onto that.
The module is priced at US$850.
 
Add a day of EagleCAD PCB design, a quick Seeed Studios PCB production run and a quick transplant of the connect from an 2GRFE ECU plug and you could have a custom ecu for a 2GRFE for <$1000....

I'll buy the $4k camry on ebay, you buy James' SW20 shell and we're on!
Either way one of needs a house + shed to put this all in.

Haha, I've been eyeing that Aurion all week.
Bugger buying the SW20, it'd go straight into the AW11!
 
Working on the house + shed thing :P House plans have been done, 16M x 7M shed quoted on, just need to finalise Ergon quotations, and submit it all to those guys that give you money in exchange for you soul... (I think they call it a mortgage).

Just a cool little blog from a guy putting his BMW onto a MS3

Shows some of the areas you can get caught up on and has some good bits on some specific areas like VVT.

Hi everyone, sorry to bump this thread but I need some help. :)
 
I'm running a MS DIY PNP on my pretty much stock Bigport 4AGE and it's been fine so far apart from being seriously down on power after 5000rpm.

Hoping to resolve it I've began moving over to run the coil from a single BIP373 module but I can't quite get it to work. So far I've:

1. Installed the BIP373 module and heat sink
2. Connected the first ignition jumper only
3. Ran a cable from S1 straight to the negative pole on the coil (and disconnected the previously connected one, should I have kept that connected?)
4. I haven't changed any settings in Tunerstudio as the only info I can find is to set it to "Going High (Inverted)" and it was already on "Going High" but had no (inverted option).

The car starts but idles incredibly rough and the timing is all over the place so clearly something must be setup incorrectly.

Anyone have an idea on what it might be or what I've messed up?

Check that you have the TVIS working at 4500RPM or it's going to choke.

Check that you have the TVIS working at 4500RPM or it's going to choke.

I'm reasonably sure it's working as I think I can hear it engaging a different RPM depending on what I set it to in TunerStudio. However right now the car isn't drive-able at all since I've switched over to running the ignition over the MS.
 
Here's my current tune if anyone could perhaps see any issues with it. The car just about starts but checking with the timing light it's all over the place.

I recommend using the stock Toyota VAST ignition system up front as it takes care of running the coil with correct duration and dwell times and is the easiest way to get it up and running. It also connects to the trigger sensors in the dizzy and provide a nice clean square wave signal to feed the ECU.
 
If you can zip up your whole project file including MSQ and some data logs of it running, I'll take a look for you.

I was under the impression that I couldn't get spark cut with the VAST setup and I read somewhere else the BIP373 setup is preferred but whatever makes the car run properly is fine by me. :)
 
What would be a better way to confirm TVIS is working than just by feel/sound?
 
Here's a log from my last track day as well as my project file zipped. Thank you very much!
