Hi,

Yes that is a standard report output from the Turbo test. The EASY will do various engine tests and the give a very detailed report with graphs and also a simple summary stating yes it past or no something is wrong! If you have a problem you should be able to get these reports from your Iveco dealer when they have done diagnostic work on your truck. They are automatically saved on the system so they can reproduce them if you forgot to ask at the time. The only down side to the EASY is the cost! I am travelling to many countries that don't have Iveco garages so it was an important investment for me.

Here is a text report of the turbo test:-

A lot of people say that old mechanical vehicles are best for overlanding, I don't think so! If you have the diagnostic computer and you take the time to learn how to use it, it is like having a garage full of test equipment and a rolling road all contained in your computer. You can diagnose so much with the computer and the engine protects itself if there is a mechanical fault. Modern electronics is very reliable and I have found most issues are actually down to wiring rather than the boxes on the end of the wires.

A quick update on my AFAM development:

I have been working hard to improve the software and hardware. I’m working with Don in Australia (www.goingbush.com) and we are getting really close to being able to offer full constructed and tested AFAM replacements, either as a PCB to put in your original AFAM cases, or as a complete unit in its own case. Here are the new features that I have added in addition to all the normal functionality:

1. When the ignition is turned on, the unit will check the existing state of the locks. If the parameters are still within limits, i.e. vehicle speed and sequence, the lock solenoids will be automatically reengaged as appropriate. If they are no longer required, they can be deselected in the usual manner.

2. If the vehicle is stalled, the unit will remain powered for approximately 5 seconds after the ignition is turned off. This should allow enough time to turn the ignition off and on again, so that the engine can be restarted without any of the selected locks disengaging.

3. To engage more than one differential lock, it is no longer necessary to wait for the previous lock to engage before making the selection. You can now select all the locks you would like and the unit will engage them in sequence as soon as it is possible.

4. To disengage more than one differential lock, it is not necessary to wait for the previous lock to disengage before making the selection. For example, you can now deselect all the locks by simply pressing the ‘centre differential lock’ button. The unit will disengage them all in sequence as soon as it is possible.

5. To engage the rear lock only, stop the vehicle and press and hold the ‘rear differential lock’ and the ‘front differential lock’ buttons simultaneously for about 2 seconds. If the rear lock is the only lock engaged, it will disengage automatically at about 30 kph. The centre lock can be selected and then the front lock selected if required. To disengage, simply press the ‘rear differential lock’ button.

6. To turn off the ABS, press the ‘front differential lock’ button until the small ABS light illuminates. Pressing the ‘front differential lock’ button again will turn the ABS back on.

7. Pressing and holding the ‘centre differential lock’ button until a long beep is heard, will engage the centre differential lock, but the automatic disengagement at speeds above 80 kph will be disabled.

I have been testing this extensively through the Amazon in Suriname, Guyana and Brazil and it has so far worked very well; far better than the original. The locks just ‘go in’ when I want them!
Here is an example of the kind of conditions in which it has been tested in the Amazon: http://www.tuckstruck.net/driving-the-br-319-with-free-pants-and-a-soup-tin/

Don has also been testing the AFAM in Australia. Here are some videos that he has produced showing its functionality:
Video 1 Rear diff lock only operation: https://youtu.be/aIHd6nQYr0o
Video 2 Centre, Rear & Front diff lock test: https://youtu.be/U-E_LMzYD3k
Video 3 Centre diff lock with speed drop out disabled: https://youtu.be/SX3xD3u_YFY
Video 4 Activate Centre, Rear, Front plus auto disengage & ABS OFF: https://youtu.be/VZu3wU0sVPc

Once Don has received the ‘production’ batch of PCBs, he will be starting to manufacture them. I will add a link to his website so anyone interested can order them from him. Unfortunately, life on the road means that I can’t really build them for others, but I have been working with Don to fine-tune the circuit design and software.

Well the electrical design has improved and so has the software. As I am on the road travelling I am unable to make them for others, however, Don in Australia has taken on the challenge! They are now being built in Australia if anyone would like one, see http://www.goingbush.com/afam.html

Marcus,
I have a lever to engage and disengage the center lock, and one button for rear and front lock respectively*. I can engage (and disengage, of course) them at any time any speed, anywhere.
What is the disadvantage of my arrangment?

I've driven old vehicles with simple mechanical engagement systems, they are great. However, Iveco decided to make it a bit more complicated and added some 'safety' features so you don't damage the drive chain with poor selection choices or loose control of the vehicle driving too quickly with locks in (there are a lot of people out there that don't really understand what they are doing with diff locks - this is probably why Iveco added the electronics). When you go into the maths of the gear ratios and engine torque you quickly realize it is quite easy to damage the front axle. The only problem is the original AFAM computer has really bad software, I am sure the hardware is good but I cant access their PIC to reprogram it. Everyone I have spoken too with the original AFAM complain about how hard it can be to get the locks to engage, it is not the actual looks that is the problem, it is the logic (or lack of it) in the AFAM.

Anyway it is always good to get a bit of banter on the forums :-) I will keep all the electronics and comfort of the modern vehicle over the discomfort of old mechanical clunky trucks......

Me too - but the other way round!
Look, I´m 60+ now and I grew up with the advantages (and some disadvantages too of course*) of engineered - and not electronicised - vehicles.
When you and I will meet - somewhere, sometime - I will tell you how I managed to come back home from Norway with a front axle CV-joint broken (without diff lock of course) at my ´64 DKW Junior. This was my first (and the only one person mobile home I know) I owned.
This one:

was the fourth or fifth (multi person obviousely!!). 4x4 but no locks, neither back or front, center lock was permanent...

Our Iceco Prototype seems to be the ultimate vehicle for my wife and me (she´s the one stepping out of the bus).

P.S.: I agree about the banter

Hi Marcus

Congratulation for your great work in this DIY-Project - to find out all functionality and improve it.
And you aditionally do a lot of work to give your solution to other Daily users.
The circuit PCB has a clear layout helpfully for easy mounting the parts.

But from my professional view as an former developer of automotive circuits (which i can`t stop)
i see also some problematic aspects at the PCB - level, which will i give you as information, not critic.
I understand this is as an functional circuit - not an commercial automotive product.

my points are:
the Arduino socket pin connectors aren't vibrationproof - this kind of connector is never allowed
in automotive industrie designs,
no powersupply smoothing (is there a powersupply cicuit ?),
no Protection for In- and Output pins (with Capacitors, Resistors),
no Overvoltage protection for circuit (by Varistors, Transsil diodes, etc),

So if you would get "sold out" and run it at more commercial level you should add such security circuits
at next board design.
Until this give users the hint to stick the boxconnector never under power.

regards

Erich

Hi Eric,

Thanks for the advice it is appreciated. I was also looking to use surface mount components too but they would be very difficult for 'home construction' but would increase the vibration tolerance. To try and reassure you of the design this is what I have done. For the power supply the maximum vehicle voltage according to the Iveco documentation I have is 15.7V - obviously something could go seriously wrong with the alternator and a higher voltage could be produced but that would probably cause other problems too. The Arduino Due power input range is 6 to 16V and it does the voltage regulation 'on-board' (this regulated supply feeds the pull up resistors in the input circuitry to provide stable input signals). However, it is recommend to try and keeping the voltage below 12V so the Due's power circuit does not get too hot. In the power circuit I have added two large diodes, chosen because they have a quite large forward voltage drop, just over the standard 1.2V of a silicone device, so a total drop of over 2.4V. In testing I have not seen the supply voltage to the Due go above 12V or the Due's temperature above 35C, even when it was 30C in the cab driving through the Amazon Jungle with the widows open (I have an LM19 monitoring the systems temperature in the prototype). The Due maximum operating temperature is 85C. The Due is attached to the underside of the board on the header pins but there are also 6 standoffs 'bolting' it to the board so it should be quite vibration resistant (sorry the one in the photo above doesn't have them installed, we are awaiting their delivery). The AFAM box it is mounted in is also on vibration isolators and the box that Don supplies also has a water seal on the lid, something the Iveco one does not have! Four of the six switch signals are open circuit going to ground so I felt that there was little need to protect them and the two signals that switch open circuit to high (actually switching to a supply provided by the AFAM circuit) do so through a resistor potential divider and transistor which could handle an input voltage well in access of 16V. The speed and rpm signals also go through a resistor potential divider and transistor network. I did not design the circuit allowing for someone to start putting 12v where it shouldn't be, although given the quality of Iveco wiring looms that may have been a good idea. The circuit design and software have changed considerably from that shown on my website. The website was very much my first prototype, with version 1.7 software, the ones now being produced in Australia are on the second PCB design and are using version 8.6 software.
