Is it possible to phase out Jeep ECU with an engine swap?

[Christian.mers]

Is it possible to phase out the jeep ECU while doing an engine swap? Could you wire the gauges and all the stuff people typically save with the stock ECU for on a separate ECU (Hypothetically let’s say this separate ECU is a Holley of some sort)

97-01 Dash uses a CCD bus to talk to the dash 01.5-06 uses a PCI bus so you'd need a PCM to talk to the stock dash. Now if you replace your gauges with something aftermarket then you could eliminate the stock PCM.
@Shank is doing a LS swap in his LJ and eliminated a lot of the stick wiring but is still running the stock ECM.

Actually the stock ECM is gone too, just running the GM one.

I couldn't remember. But you aren't running the stock gauges right?

Dump the PCM and install a Auto Meter direct fit dash and gauges.

Correct, I am running aftermarket gauges.
