Thanks for the tip, I dont remember reading anything about BIP373. Do you have a link explaing this driver and its install process? Just a quick question. I noticed you don't have a BIP373 ignition driver installed, so are you using the standard Toyota VAST system to drive the coil and provide the tach input for the MS? If so, I advise you install a BIP373 to run the coil, because with the VAST unit, if you use spark retard/cut limiter, the motor won't actually spark cut (The VAST unit returns to 10' timing in the event of no timing signal IE: spark cut) and it will keep revving. You could rely on fuel cut, but anything running boost + fuel cut isn't a good idea in my books. Keep up the good work mate, rep'd you on toymods too

The BIP373 gets installed in Q1 in the ignition section of the board  This is the BIP373 kit - http://www.diyautotune.com/catalog/diypnp-upgrade-bip373-ignition-module-and-heatsink-kit-p-387.htmlIn other news, there is some real progress happening with the MS3 and running VVTi  Won't be long till MS3 will be able to handle a 2GR-FE with all the bells and whistles activated! http://www.msextra.com/forums/viewtopic.php?f=125&t=38890

Just reminded myself I should post in this thread. In 2011, I swapped a 4AGE 20V Silvertop into my AW11 and the stock ECU died a capacitor leaking death during the swap. So I bought a DIYPNP ( http://www.diyautotune.com/diypnp/) with Sequential Injection board from DIYAutoTune (Same blokes I bought my MS2 from). So I thought I'd share a quick couple of photos and videos while I'm here. When the kit arrived.  Mostly assembled.  A wiring translation table I did up  I had a bit of a struggle to get the stock VR sensors to pick up a reliable RPM signal, but soon discovered I was missing a resistor on the cam sensor (specific to Toyota dizzies). This fixed the tach signal, but I then discovered I was getting sync issues (related to sequential fuel/spark setups). This turns out to have been caused by the fact that the CAM wheel is snail shaped, and when set to "Rising Edge" detection, ends up detecting early. A quick switch to "Falling Edge" fix the problem instantly, giving me a nice RPM signal, with no sync errors. First start. http://www.youtube.com/watch?v=N16HQMd9TfU Learnt very quickly that 2 squirts/cycle settings doesn't work well with sequential fuel injection, hence the WRX sound and lack of ability to rev. Change the settings to 1 squirt/cycle and it sound much better, as shown here: http://www.youtube.com/watch?v=0ee9OuOCSl4 But I still have a vacuum leak, hence the idle at 3000rpm. I also had trouble getting a lower idle KPA on the MAP sensor with the ITB's on the 20V. I fixed that by shifting the vacuum nipple points on the ITB and switching the fuel load algorythm to ITB mode (Alpha-N[TPS] blended with Speed Density[MAP])I fixed that and then took it for a drive. http://www.youtube.com/watch?v=rQF3EcFjxSg The stock generated TunerStudio fuel and spark tables were good enough to drive around without running lean or knocking, so was quite happy with that. I just need to fix a few mechanical issues that developed on the car and then I can take it to the local dyno to get tuned. Oh, an actually finish setting up the VVT! I really like the DIYPNP 1.5 units, they simplify a fair chunk of the DIY complexity of installing a MegaSquirt into a car and have plenty of input/outputs available. If you can afford the extra cash, I'd recommend one over the normal MS1/MS2 kit. I think the next thing on my list will be to buy a MS3X for my 1MZFE V6 to play with :)

In case some people are not sure, i have the following setup with the ECU: -peak and hold driven injectors, 880cc delphi low z dequential -4 1zz COP sequential -4 bar map sensor with barometric correction -using stock dizzy VR pickups with an aluminium cap i got from the group buy long ago -w/a pump, engine room fan will be switched/controlled via MS3 -boost control -launch control -2 maps switched via a push button -TVIS controlled via MS3 -Considering using my Carpc for displaying oil pressure and temp via some senders -Can autotune -Can use speed-density as load, or ITB load tuning (looking forward to experimenting) Currently im trying to figure out the last piece of my puzzle, what to do with my throttle body. stock 93 gen2 but i want it as sidefeed

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.... ****... JUST... GOT... REAL...*Someone please buy me a 2GRFE so I can develop this....*

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.
 Go soothingly on the grease mud as there lurks a skid demon.

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 http://m54megasquirt3.blogspot.com.au/ 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.

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. https://drive.google.com/...hvU1U/view?usp=sharing

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.
