With some more time to spend on exploratory development I've taken a project off hold. This is the MiniDash, which is intended to be a 52mm pod gauge with a 1.

This is just demo data for now, updates to follow over the next few weeks. Its a stunning build with absolutely everything DIY'd himself down to the manifolds. The CORE4 runs! The power supply circuit, usb and injector drivers are all proven out now. Got the processor and bare minimum components installed and managed to load the bootloader and a basic blink application. Now it's just power, IO and serial Comms to go. Another mx5 up and running on the speeduino PnP.

Great to see people s project progress.For all the Miata and MX5 fans out there, the new v1. Jump to. Sections of this page. Accessibility help. Email or phone Password Forgotten account? Sign Up. See more of Speeduino on Facebook. Log In.

I gave the last stream a miss as I had the Dropbear preview to do, b I'll be diving into something a bit more technical this time around and breaking down how the trigger decoders work and what's involved in creating a new one.

If you've ever wanted to know how the trigger wheel on your crank gets turned into RPM, crank angle etc, then tune in to this one! See more.

A know there's a lot of interest around the Dropbear unit I showed s Ok so if there's been 2 constant questions in the last few streams i In this weeks stream I'm going to be talking all about the latter!The v0. Note: The v0. The 2 are designed with different goals in mind. Unless you understand the interface on the v0. Note that there are some differences between the various versions of the board, however the pinouts on the main IDC40 connector remain the same.

See Injector Wiring for more specific details. Assembly of a complete board is virtually identical to the v0. Whilst it does not technically matter which order components are installed, the following is recommended for simplicity:. Take note that C14 and C16 are polarised capacitors, meaning that they must be put in the correct way around.

On the PCB, the positive side is indicated by a line on the capacitor symbol. All assembled boards will typically have the hole on the bottom. The board can be configured in multiple ways depending on the hardware you use and way your setup is configured.

Multiple functions within Speeduino have adjustable outputs or can be set to Board Default. The following are the Default pin outs for the v0.

If using a VR crank sensor, the board will require the addition of a VR conditioner. These have been out of stock to purchase directly for some time but can be built from the parts list as the instructions are still available. There is also an official VR board that can be purchased from the speeduino shop which also plugs in directly. Other 3rd party VR conditioners will also likely work but obviously not all configurations can be validated.

Depending on the type of crank and cam sensors you have, there are a number of jumpers that will need to be set. Some VR sensors can send high AC voltage into the arduino board.

If you are unsure of your sensor type identify it before connecting it to the board.

The pin IDC is the connector that was used on computer drive ribbon cables for years and old computer cables can be used. A heavier cable, called DuPont cable is recommend for long term use though. These cables are NOT compatible. Some of the pins are connected together causing the magic blue smoke to be released.

Whilst it does not technically matter which order components are installed, the following is recommended for simplicity: All resistors All diodes Including LEDS All capacitors Take note that C14 and C16 are polarised capacitors, meaning that they must be put in the correct way around.

Place the board over the top of the pins and solder in place Note that not all the pins on the end double row need to be populated Though there's no harm in doing so.

The odd numbered pins Eg D23, DThis is all 1. In particular, please see below in the fuel pump section for details that must be understood prior to starting. The PNP box plugs straight into the stock wiring in place of the original ECU, however some hardware changes are either recommended or are desirable in most installations. This unit can either be retained or removed, but if being kept in place, the connector to it should be disconnected.

For a load reference, it is strongly recommended to run a manifold pressure line to the Speeduino PNP box. This allows Speeduino to run in the default Speed-Density configuration and is usually a fairly easy installation. The unit comes with a built-in MAP sensor that supports up to 1 Bar of boost, but is compatible with other external sensors if more pressure is required.

The 1. The original wiring can be used with any 3 wire VTPS. In the stock configuration, inlet air temperature is provided by a sensor in the AFM. If the AFM is retained then this sensor will work if jump wires are run from the AFM to the disconnected connector See image belowhowever as most setups elect to remove the AFM, an additional sensor needs to be added. The 2 wires from this sensor can be pinned directly into the AFM connector on pins 1 and 6 It does not matter which wire goes to which pin :.

Whilst not mandatory, the installation of a wideband oxygen sensor and controller is strongly recommended. The wideband analog output signal should be connected to the original O2 sensor wire. This has a convenient connector in the engine bay, located just next to the coils.

This can be found by following the wire from the original sensor. If not reusing the original narrowband sensor, the connector can be cut from this and attached to the wideband signal. Failure to remove this fuse prior to powering the unit on will trip the smart FET that is used on this line, but should not cause permanent damage if only performed once or twice.

If the above method of fuel pump control is either not desirable or not available, an alternative driver wired to pin 2O on the main connector that can be used for this. Wiring on the pin 1. In addition to other points on this page, the following should be observed for 1. It is strongly recommended to start by using the NA6 base tune that is available through SpeedyLoader. The stock sensors can use preset calibrations within TunerStudio. To do this, a jumper wire is required on the AFM connector per the below: Once the above jumper is in place, the fuel pump pin in TunerStudio should be set to A9.

This should only be done in this specific case and it is unlikely to affect most cars.Open, cheap, hacker friendly engine management. Not a member? You should Sign Up. Already have an account?

Just a quick update that I've at this 11th hour finally finished off the project video for the Prize, of which Speeduino is a finalist! It briefly runs through the history and motivation for the project as well as where it's going in the future.

A little late this month due to a few bugs that have taken quite a lot of time to resolve, but the September firmware is now ready to go. I know a few people experienced some comms issues with the August release and that prompted me to not only fix those issues, but make some major improvements at the same time. I know this doesn't necessarily benefit everyone, but I do want to make sure these are working really nicely before the units go into wider production beyond just the Beta units.

The full list of user facing changes is below:. So time for some more new firmware goodness! I've gone back over the feature request list and tried to get through as many of them as I could, including a few that have been requested fairly regularly for a while now. These have been in the works for a long time and, whilst some development is still required on the firmware side of things for them to be perfect, they are ready for wider testing and use: The major changes on the firmware front this month were:.

Another month, another firmware drop! As is usually the case, there has been a bit of behind the scenes work happening in the firmware that is designed to both increase general stability as well as preparing for some more core changes that are coming in the next month or two.

There's also been a heap more work on the manual, in particular the layout and formatting of the offline manual. The whole thing is considerably easier to read and things like images are sized correctly etc. As always, if anyone is interested in helping out with the documentation, just let me know. The MISRA standard is a set of coding guidelines designed by the automotive industry to maximise reliability and safety in software used in vehicle systems.

About half the code is now compliant and I expect to complete this effort within the next few weeks. Where does the time go? April already and March has been another big one for Speeduino. Forum users and installs are increasing all the time and it's terrific to see the project starting to be mentioned more often on forums etc as a truly viable system! As a heads up, I plan a slightly quieter month throughout April on the firmware front. I will still be doing general maintenance, bug fixes etc, but probably not so much work on new features.

DIY Engine Management Systems live and die by their documentation and to date whilst Speeduino's documentation has been minimally OK, I would like to bring this up to a much more professional level.

I've already begun restructuring a few things, so there are many placeholders there currently as indicators of what I will be adding.

If there is anything you find that you believe is important, but that doesn't already have even a blank page, then please drop a note in the forum and I will look at adding it. If you have some time and knowledge to share, please do contact me and I can get you the required access! So after the big release of sequential control in October, Novembers release is less focussed on features and more on under the hood changes, although there have been a few new functions added.

For the most part though, November is a stability and bug fix release, with heaps of patches included. Many of these are around sequential and a big thanks goes out to Dan Elliot for testing throughout November!These are a bolt on tps setup for 1.

They use a simple adapter harness to plug and play directly to the OEM tps plug to work with most engine management right out of the box. Tory Tyler verified owner — December 19, However, the readings my megasquirt see from the vTPS fluctuate at cruising speeds, causing the TPS fuel enrichment to trigger. The harness and adapter are flawless.
