Is possible change the output pins for steps gen for 7i43?
In pncconf the pins are
01,03
13,15
25,27
37,39
Can I change that pins for
33,35
37,39
41,43
45,47

Is because i have optocoupled interface that use these pins as outputs.

Yes but it will require compiling a bitfile with that specific pin-out
can you make a complete pin-out list? If you do I can make a matching bitfile

That's a very generous offer from PCW, but would it not be simpler to make a crossed-over cable?

Yes of course, but my interface card is ready to use, i don't want to remake it.

Andy meant to build a special cable from the mesa card to your interface card.

Note that the custom firmware that PCW will make will not be useable with pncconf with out changing pncconf.
The released version of pncconf does not search for new firmwares in the firmware folders.

pncconf wont work but the bitfile and HAL will work fine
you just need to edit the HAL file by hand

Not sure what the question is....
No driver changes are involved in changing pin-outs
