Yes it can - but thats why you have a speedo.
It can be done by itnerfacing a PIC or Atmel microprocessor which I started to do at one point but lost interest after blowing up the CPU. I'll buy another CPU and get started on it again if enough people want to be able to do it.
I could sell the kit to make it, offer up a list of parts if you want to source them yourself, or just sell a prebuilt kit.
heh, AJ.. You know i am interested in this little "kit"..
if you do sell them, how much?
another thing.. i know the mfd only reads the speed once, does your kit keep refreshing the speed like a refresh rate in the mfd?
The kit i designed will be able to keep the speed displayed on the TID constantly with the engine running. and will have a refresh rate of 8MHz - well the CPU is 8MHz.
All I need is some more CPU's, its best to buy these in bulk since the postage per CPU bought seperate pretty much doubles the price, then its the PCB that would need to be mass fabricated, but I might just etch them myself and drill them myself as well.
I'll order a single CPU at the end of the month, probably about £10-£15 and then I'll start redeveloping it. Theres only like 2 places you can get them from online.
The only pain in the butt would be the fact that the speed reading would be engine dependent.
ie, a 1.2 8v sparks at a different rate than that of say a 1.6 12v.
I'de need to find an easy way of getting this sorted accuratly, whether thats by using a potentiometer (not very accurate) or a couple of DIP switches, or just program each CPU with the correct timings before shipping it out.
Obviously this is the fastest the CPU can run at, but take into account the commands that will be running, and i'll probably enable the CKDIV8 pin, so it will run at more like 1MHz top speed, but the MFD might bottle neck it if it can only refresh itself at a lower speed
where i would put them? im thinking 4D.. you have to go back in time to fit them.
what i would like to do is have them just above the MFD.. sticking up..
just 2 IN-14 or IN-16 tubes. would look mint.
only thing id have to figure out is how to link up the nixis to the MFDs LCD display.
if i could do it with a PIC micro controler or somthing else.
thing is,this is technology i am not familiar with. so ill have to learn as i go.
