  • Been meaning to make one of these for a while now. Could never justify the price for the proper version. An old socket, screw driver bit and a bit of turning on the lathe and voila. Works really well and is easy to use one handed, which leaves your other hand free to hold the feeler gauge.

    DIY dynamic balancer
    Posted on Monday, 24 April 2017
    Have long thought about building a dynamic balancer. Very useful for crankshafts and blower rotors. Easy enough to build a very simple balancer and nowadays not too much more difficult to build an accurate one. Electronic controllers are very accessi...

    Twin plug
    Posted on Wednesday, 12 April 2017
    Lots of reasons for going to twin spark such as less timing, cooler more complete burn and a more detonation resistant engine. Here's some jigs for drilling for a second plug

  • Great to catch up at Parkplatz tonight but we had to make a hasty exit when the parking warden arrived. Sucks that they have made the car park 24 hour pay and display. Definitely time to find a new venue.

    Checked out Cafe Troppo on the corner of Whitmore Square and Sturt on the way back home. Looks like a nice spot, plenty of free roadside parking, they also have alfresco seating so can keep an eye on cars and open till late. Might give there a go next month.

    Right then. It's time for a change.

    There's a few SA Dubbers that have a hard time making our Saturday night meets, so the logical thing is to move it to Friday night and hopefully attract more participants. So instead of the meeting being the First Saturday of the month, Parkplatz is moving to the first Friday.

    This means the next meet will not be Saturday 1st April but will instead be Friday 7th. I will post up a revised event listing.

    Don't forget, there's also a coffee and cars type event called coffee and chrome at the Mile End homemaker centre on the first Sunday of the month (Sun 2nd April). See you there!

  • Made up a valve spring compressor out of stuff from the scrap pile today.

It's basically a bit of 150mm x 5mm flat bar for the base, a couple of lengths of angle to support the pivot bar and a handle that slides on the pivot bar that in turn pushes an arm to release the valve. I found a suitably sized washer to fit the valve spring retainers, it was deformed into a slight concave shape and so fits the retainer nicely without sliding off.

    I also added a couple of bits of angle to help hold the valves in place when operating it and a small bit of flat bar at the rear to locate the cylinder head against. I made the pivot bar removable by securing it with 'R' clips. This will allow me to remove the lever arm should I need to.

    It works really well, much easier to use than the regular clamp style compressor that I normally use. Well worth spending a couple of hours on.

    Beehive springs
    Posted on Thursday, 30 March 2017
    Some info on single beehive springs. The biggest benefit of a beehive spring is that you can use a retainer of a smaller diameter - less weight. A bugpack or berg retainer is roughly 21g... a retainer for the PSI spring is roughly 11g (the same as...

    Thought I'd dig out the ECU's that I have take a photo of them and give a little bit of info about each one.

    First up the onion board. The onion board is not really an ECU, it's more of a signal processing board. This board is designed to work with the FreeEMS code and to be used as a piggy back board to a MC9S12XDP512 processor board. I suspect that it would also work in LibreEMS as this is also MC9S12XDP512 based being a branch from the original FreeEMS code.

    The S912XDSYS is a MC9S12XDP512 processor mounted on a convenient breakout board that is also coupled with a clock crystal and BDM interface to allow communication with an external boot loader. This board in conjunction with the onion board is typical of the hardware that is available for the FreeEMS / LibreEMS projects.

    In short the MC9S12XDP512 is a processor that has a variety of I/O that can be programmed and configured to work in a number of different ways. The actual use of each of the I/O channels requires external componentry to ensure that the signal is converted into a format that the MC9S12XDP512 can read. This is known as signal conditioning. Boards such as the onion board simply house all of the signal conditioning required to interface with the typical components that you would need in an EFI install on one easy to integrate board.

    The MC9S12XDP512 is very flexible in that you can easily write code for it and it is relatively simple to create hardware required for signal conditioning the I/O to work in the manner that you want. Of course simple does not necessarily mean quick or easy which is why one of the solutions already available like the onion board is a good bet.

    The small boards are more signal conditioning boards. These are VR signal processors that take a crank trigger signal and output a nice clean square wave.

    The two square boards are Speeduino boards. These are also signal processing boards, The main processor used is an Arduino Mega board. The Arduino is a bit slower and has a little less memory than the MC9S12XDP512 but it is a very stable platform and has a proven record. For my application it is a very good fit and it's appeal grows on me more every day.

    The Megasquirt unit is a basic V2.2 board. This is one that I built myself, it still needs to be modified to drive the ignition circuits but is functional and ready to install. This is kind of the industry standard for DIY ECU's. it's relatively cheap. It's easy to assemble. Widely supported and is still better than some of the oppositions offerings even though this particular board design is over 10 years old. Standard the board is only designed to be fuel only, however some bright spark managed to mod the board and firmware to also take care of spark. That's the great thing about open source.

    The 'MegaStim' unit is a way of generating accurate field signals so that the ECU can be tested that will function correctly. It's basically a simple timer board with outputs that mimic the crank trigger and sensors. There's another similar stim board called an ardustim that utilises an Ardunio to generate the required I/O.

    Last in the line is my DTA unit. This is an older unit that runs fuel and spark and is still capable today. This is not really a DIY board but deserves a mention.

    I've just received notification that I can expect my parcel with the coolEFI in it to arrive soon. I will post up some details when I get it!

  • Been working through getting the EFI install on the bus ready so thought I might as well share the info here for others to find. Also got a few ECU's that I want to test with a view of supplying a basic ECU with the EFI version of my supercharger kit.

    Been working through getting the EFI install on the bus ready so thought I might as well share the info here for others to find. Also got a few ECU's that I want to test with a view of supplying a basic ECU with the EFI version of my supercharger kit.

    There's a bunch of good DIY EFI solutions out there, some are well known, such as the earlier Megasquirt MS1 and MS2 boards, some are relatively new such as the Arduino based 'Speeduino' and others are open source such as FreeEMS or LibreEMS.

    With the Megasquirt and Speeduino solutions you get both hardware and software. The hardware can be purchased as a kit or already assembled, The firmware differs drastically - the Speeduino is open source and so is free to download and use. The Megasquirt has limitations in it's usage. For example it cannot be used on any other hardware other than a genuine Bowling & Grippo board. This excludes those wishing to make their own hardware from using it.

    The open source FreeEMS and LibreEMS follow a very different model. The software itself is the main goal of the project. In each case there is no official hardware. Instead hardware has been developed by community members to utilise the software which has then been made available to the community. This is a bit weird if you ask me and also makes FreeEMS and LibreEMS less accessible than Megasquirt and Speeduino.

    Both FreeEMS and LibreEMS provide all of the information that you would require to design your own hardware and in fact encourage this, however it does place both of these solutions out of the reach of most tinkerers. There are third party offerings such as the coolEFI board available for LibreEMS and the RUS board available for FreeEMS.

    At the moment I'm getting ready to assembly one of the Speeduino boards that I have. The RUS board is on my list to assemble next and I'm waiting to take delivery of an assembled coolEFI ECU.

    The plan is to work my way through a bunch of different ECUs and will do some comparisons, this will then allow me to make a decision on which unit to supply with my blower kits.

    Up until now my favourite was the coolEFI board as it has everything I need and has a very good price point. However I've currently been waiting months for my ECU to arrive. This doesn't give me a lot of confidence.

    My current favourite is the Speeduino. It has all of the features I need and the price is very good, however it gets talked down by some of the other ECU devs due to its slower clock speed speed. There's now a bunch of people running it so the proof is in the pudding, it's working reliably on quite a few cars now so the slower clock speed does not really seem to be an issue.

    The other great thing about Speeduino is that the developer has got it to work with TunerStudio, including utilising the auto tune feature.

    Ive already got an MS1 ready to go that I built up a while back but still got a bunch of stuff to work through before the bus EFI is ready to install. One of these is the loom. My plans are to make a peg board so that I can replicate the loom multiple times.

    Will keep you posted
