Has anyone experimented having dual pcm in a vehicle?

Is it possible?

Is there advantage of having two pcm connected someway/how to choose on the fly with different presets?

PCM 1 for daily use then PCM 2 for power racing.

Or is it a stupid idea?:confused:

There is an 05 operating system that would do the same job with just the one PCM.Cheers Scotty

Not possible to have dual PCM's, they would clash with each other in many ways.
The Diesel guys do have the luxury of being able to switch between five different tunes on the fly, however, Diesel tuning is very different to gas.
With gas tuning there is no real need to switch to different AFR's on the fly and with the PCM have adaptive spark timing that is taken care of from the factory.
