digi dash options?

[baz-r]

ok who has got a digi dash thingy? i orignaly was going to go new dials as my sierra one was peeling away on the dial paint but cable speedos are a pain/expensive to cal and eletronic dials bundeled with matching gauges are not cheap tbh so i was looking for a tiny speedo and dials seprate but it looks as if i can get a whole digi dash for about the same price as a stand alone digi dash
acewell 3000 series looked better than the trail tech vapor as it does fuel but how to thay work on a running car? and any iva issues?

i had a look in the iva manual and it says

Note 1: The speedometer must be of a type suitable for M1 vehicle use. The types manufactured for bicycles, racing only, those that rely on GPS or those that require switching as a separate function to that of operating the vehicle or those that have a separate power source from the vehicle or where they do not operate as an automatic function when the vehicle is driven are not permitted. Where the device is in question the presenter may provide evidence as to the suitability of the device for road use from the manufacturer of the device
