Thread: Any way to have multiple tunes and switch between them, without reflashing?

now that's what I'm talkin' about.

I'll take a look at seeing if I can find that write up, thanks for tip, I did a search but didn't see anything, but didn't know what terms to search so I was using Diablosport and such. As far as using a laptop, I understand, but once you have everything set then why not be able to switch almost on the fly? I mean if this was available for Fords back in the late 90's why wouldn't it be available 10 years later for GM products? Yes different systems and all, just thought we'd be farther than this.

as far as doing this with a PLC, it's not even complicated enough for that, besides too many I/O and too much analog. The systems I did had 64 inputs and 32 outputs and no analog. I used 4 pole relays to have PLC A on the NC contacts PLC B on the NO contact and the system on the common. A switch to select A or B, simple. With relay contacts you can pass analog signals easily for most signals. It's still not very practical.
