couldn't find anything on the search or google. Can you cheaply and effectively make your own 02 sims? Like the $1 resistors used for !cags and IAT mod etc?
1 I'm cheap!
2 I like to make **** myself, if I can

Buy one, get out the multimeter and test it, make your own, see if they work, sell the one you bought.

If it was me, i would just have the codes tuned out (for everything). MTI did all my codes for $75 and that's still cheaper than buying O2 sims.

electronicly? no.
but someone here posted about something i never heard about.... a mechanical O2 sim... you could try that at home.
thread is here: https://ls1tech.com/forums/generation-iii-external-engine/465337-has-anyone-ever-tried-mechanical-o2-fix-instead-sims.html

read that thread, not really interested in that route.
Why is not electronically possible? What's so special about the ones Casper etc sell?
Not getting a tune yet, when the time comes I'll just edit them out. But in the meantime..
Plus, like I said, I just like to make **** myself.

well, you COULD make it, if you know electronics well enough.

reason i said no was that its not as simple as a resistor.

you need to send out a pesudo signal for the O2 signal wire.. otherwise the PCM thinks the O2 is dead...
for the heating element pins, you could fake that with a resistor.

i would think a 555 timer circut of some sort would be close enough for the signal.. if im right, you could make one really cheap.. and then put it in a water tight case or something..

I would think if it was as easy as the !CAGs someone would have figured it out and made it pretty damned popular by now...

here ya go..
right after i posted, i did a google search for "o2 simulator circuit 555"
this came up near the top... looks like what you want:

cool deal. Don't even know what I'm going to do right now. Might just wait and do the exhaust and cam at the same time and delete the 02s with a tune. Still trying to decide if I want to do everything at once, or in 'stages'

i would still delete them in the tune.. not with a device.

but if you want to tinker, you can make it, and while you dont need it, test it out.

id make one with a old O2sensor plug, so it just plugs in...

my buddy bought one from o2simulator.com, it was like $35 and still had no plug, had to be spliced. This set-up seems like it would be kind of bulky. I'll prolly just wait and have them deleted. But, who knows, maybe I'll get bored one day.

I made some for a friend and it was fine

so, please explain. What did you use? How much? How big? Inquiring minds want to know!
