Digital Dash for Carbureted Vehicles

Throwing another option into the mix for a digital dash. AEM makes a CAN module that will drive a proprietory digital dash for carbureted vehicles. As someone mentioned in a previous post, a digital dash requires date to be fed from sensors, which in a very brief summary requires an ECU (computer) with its appropriate harness, CAN bus interface, software, etc. There are a number of proprietary systems out there that are similar to Real Dash, but inherently there is most likely no simple nor low cost answer for this type of retrofit for a vintage (carbureted) and analog vehicle.

However, I do love the idea of mounting a dummy OBD II port to the underside of a vintage mustang if your state is requiring you to go to a smog inspection or referee. That would be funny.

On another note, Mustang Project does have a kit "EngineState Pro Plus" to display virtual gauges. It's not OBD II, but I think it will accomplish what you are looking for and it is relatively affordable ($249.95).

Couldn’t he just run all his sensors to a fox body ecu and use the obd port to export the sensor readings? The ecu would just be used for collecting data to send to a phone/tablet for gauges and not used to control fuel/timing.

I’ve thought of doing this myself as I have a carb/points 5.0 in my 65 and have an old iPhone (4S) installed in the dash:









I now have 2 spare iPhone 7s phones to try for a larger screen but may go full iPhone xr for an even bigger screen. The phone currently uses its gyro for speed readings but most phones/tablets have the ability to read all motor parameters if the car is obd2 and offer multiple dash screens using already available apps.

Any reason not to believe running coolant temp, oil pressure, fuel pressure, tach, fuel level, etc sensors to the ecu wouldn’t work even if the ecu is not used to control fuel/spark? Essentially a dummy ecu for the sole purpose of having all the sensor readings sent to the obd2 port.

Mechanical fuel pump, carb, and points:

I guess if you installed a dummy OBDI port for the EPA testing, you could rig up mini PC to read whatever you wanted to..ha ha. Make a cammed 347 look like a lean, green machine. Not sure what to do about those exhaust pipe readings though.

I know this is an old thread, but in case anyone stumbles across it using google, while researching another project today I realized that there is a product that does exactly what is being requested here:


It takes the raw analog signals from a car that doesn't have an ECU, and puts them into ODB-II data connection. This is useful for using a digital dash, or perhaps in some places with unusual laws where the car will be required to have OBD-II for emissions compliance.

The idea of using tablets, phones, or other android devices is nice in theory...but the real limiting factor is screen size and shape...they just aren't designed to be able to display in a stock dash. Before this becomes a viable option for me they need to start making rectangular screens roughly 18x8"...and I just dont see that happening anytime soon(if ever)

Say what?
Maybe he wants to mess with the state inspection guy

Ya know... ask and you shall receive. The last time I took my 66 for state inspection in NJ which basically all they checked was emissions. They plug into the OBD and simply check for codes. No codes you pass. So they failed to locate the factory OBD under the dash then went looking under the hood for it. I am not kidding! Oh I passed

It's a neat option.

For replacing the stock gauges though would you need one big 18" screen? I think two 5x5" screens plus three 3" screens could make some interesting gauge replacements and fit in the original (67/68) bezel. It'd be a lot of work but it might be just the thing to finish off a custom interior.

I say 18" because I am thinking of a 65-66 cluster, but dual screens would work fine to display gauges.....except for one fact...the programs built to display gauges do not have dual screen output capability...they universally display on one screen only....though I suppose its possible to use some windows-based program and output it to dual screens...but at that point you can buy an odd sized LCD display in the 18x6" range from AliBaba or something and make it worked with something like a car-pc
