Project “Tomahawk”

[ghetdjc320]

The gauge cluster is officially in the hands of the Dakota Digital custom shop. Estimated turnaround is 2–3 months, but there’s no rush on my end.

 

I’ve requested that the temp, voltage, oil pressure, and RPM sweeps match the C5 Corvette layout, while preserving the overall Jeep gauge arrangement. The speedometer will read to 160 mph (no, it’ll never see that speed), and the KPH markings will be deleted.

 

We’re planning to retain the original Jeep font and incorporate the tomahawk emblem I designed—positioned just above the needle pivot, echoing the placement of the checkered flags on the C5 cluster. The temperature gauge will center at 220°F, just like the OE Corvette, aligning perfectly with the factory thermostat and fan settings I’ve kept in place.

 

The cluster will use a CAN bus module to pull data directly from the ECM using the original sensors—again, mirroring the Corvette’s approach. Factory warning indicators like the check engine and upshift lights will remain in their stock locations. However, the turn signal and high beam indicators will now be integrated into the gauge face itself, eliminating the need for bezel-mounted lamps.

 

A compact OLED display will also be added to the dash, compatible with Dakota Digital’s HDX BIM modules for real-time readouts like TPS, AFR, EGT, and more.

 

I’ll post renderings once they’re ready—really looking forward to seeing what they come up with.

Sounds super neat!

Maybe I missed it, where are you connecting the new cluster? Will it be OBDII based or run directly off of the ECU?

I’m actually not sure yet. The cluster will read the data from the ecu but it has an obd2 connector. If I do end up using the obd2 port, I’ll see if I can run some sort of splitter for it so I can still connect other things like the HP tuners to it. I like the idea of seeing exactly what the ecu sees without having to run auxiliary sensors all over the place.

totally agree,

I have seen use of OBD port splitters before. I know its not an uncommon thing.
