The dash is locked because the program is COMPLETELY different to 'normal' AiM programs. it has all sorts of different protocols and equations in it, to get it displaying correctly. So much so that any sort of change is pretty much a re-write of the whole program. And its months of work, not a couple days spent fiddling :)

Also - if you want oil pressure, it can be logged, and read on a computer, but not displayed on the dash board.
I understand what you're saying, but all that would be needed in this instance the click of a button enablement of a CAN Expansion Module (specifically a TC Hub), and this would have absolutely no effect on any other part of the OE configuration. Because that doesn't appear to be an option I've now had to spend several days proving a piece of kit from Ecumaster that will now talk to a Racelogic Vbox in order to display and log 8 additional temperature sensor outputs. There is no desire or need to display any of this additional data on the dash, which in any case most drivers barely look at.

This is a screenshot of the five different "speed" items (there are also e further wheel speed sensor values) taken from the AIM dash logging file for a lap of Cadwell Park. Don't ask me why the kmh value is lower than the mph value! I believe the front left wheel speed sensor value is what the dash will display multiplied by around 1.05 (ie 5%).

I've no idea what drives the odometer value because that doesn't get shown on the logs.

As I understand the UK regulations state that tachometers are permitted to overread by up to 10% (not mph) but no under-reading is permitted (for obvious reasons)

So most manufacturers ensure that their tacho's overread by a few percent

As it's a %age and not a fixed amount it's less of a problem than as suggested in a previous post!

Whilst that's an entirely plausible explanation, I would also consider it a convenient excuse to hide at least one "massaged" parameter (ie road speed as displayed on the dash), but it makes me wonder if there might be others.

At least it's possible to log all the parameters that are actually registered in/by the dash (113 in total) using a AIM Strada Logger on a totally plug and play basis (as long as you already have fitted a GPS aerial and an AIM Expansion Module).

Interestingly, total mileage is not one of the loggable parameters, but per session mileage is. I think it's the same on the TCR car (Ben CM will know what I'm talking about).

There are procedures in place in regard to the registered mileage should the dash need replacing or in the event of upgrading to a alternative display.

When I upgraded my 3.5 to the 3.5R spec I upgraded the dash at the same time and the original analogue dash mileage was recorded on the relevent invoice to become part of the car's FSH as the new digital dash started from zero again!

I did wonder if there was some measure of having to ensure integrity/security of some of the data due to legal reasons, like ensuring the mileage is recorded accurately.

The mileage is built into the aim dash so this is the main reason it’s locked.

This is a bit like the android vs apple approach, Ariel being the apple, they want to provide a sucker proof system which you cant mess with too much

It's not so much the IP investment issue but rather they simply don't want people breaking their cars is my best guess.

For example, there is quite a bit of arithmetic parameters they have configured such as gear selection. They calculate from speed what gear to display on the dash in the case of a manual gearbox option.

Finally, I am not sure they have the skills in-house to make changes to the dash and AiM hardware and software anyway so it is likely an easy decision to just lock it with them holding the key.

It's a real shame because AiM kit is pretty powerful and flexible used in many race cars including nascar but in Atom 4 you might as well just have an analog dial showing your speed (pdm benefits aside).

In that case, if the dash was unlocked, there would be money to be made reprogramming the dash for those owners who 'f' up their dash - win win all around! ;D

- I could understand this approach if the factory actually offered a bespoke (chargeable) dash update/modification/reprogramming service but since they don't appear to want to offer this what on earth is the point in locking the dash and preventing owners modifying the display to their own preferences?
I think it's partly to protect their investment, but the dash also incorporates a form of PDM to control lots of things like switching of lights and peripheral stuff which is probably best not open for owners to be messing with. Also, I'm aware for example that what you see on the dash as a speed readout is something like 105% of the true wheel speed sensor reading, and there may be other similar things that they don't wish to be open to scrutiny over. But it is extremely frustrating nonetheless.

To add a sensor digital or analog, you need to be able to create and map a channel and calibrate it then send this to the dash. None of these things is possible with the dash locked sadly. Basically the AIM dash is a locked brick.
Yes, but I presume when you bring in the car for service, Ariel will be happy to add oil temp sensor? But it's indeed not a thing you could do yourself when that data channel would be locked in the AIM dash.
I very much doubt Ariel would do this because they would have to make changes to your dash configuration this means testing on their part etc They will add a brake pedal sensor because there is already a mapping for this but any other sensor like steering, tyre temp, brake temp, accelerometer etc. They probably would not do.

But I'd ask them anyway to check.
