Can I do a "Limp Home" mode on purpose?
Can I do a "Limp Home" mode on purpose? I'm putting an LS6 into my '87 Mercedes and expect wonderful things with it. Since I live in Vegas, I let the valet guys at the casinos park my cars fairly often but don't want to give them an LS6 to play with.
What does it take to put an LSx engine into "Limp Home" mode and would it hurt the engine if used occasionally?
Does it (or can it) put the engine into a lower HP mode while there?
Thanks,
Mike R.

I think that there are options to do this with the tuning programs. I know that you can have a valet mode with the EFI Live 7 software, I can`t remember if you have to run an EFI Live 7 custom operating system to get it or if you can just tweak the GM OS. HP Tuners may have a similar feature.
I thought if KR sensors were disconnected it would put it in the low timing table. If that's the case, flash the low timing table even lower, put an inline switch to the KR sensors somewhere inside the vehicle and now you have a form of limp mode.

just switch between them as you see fitThe external rev limiter would be fine as well but I have no idea how to add one. Any suggestions?

Of course since EFI Live has a way to do the Valet function, that means I have an HP Tuners setup. More research.
