ok i gotta pr3 chipped with s200 hondata... i havent had to mess with it ever until rescently when i upgraded from a b16 to a ls/vtec..... well i find that hondata no longer supports these ecus...
at this point i dont have the money to upgrade to obd1 nor do i want to..
with this said what are my options??

Why can't you still use it? You should be able to get it tuned still..

the tuning aspect remains the same... any Hondata tuner can still tune it....

buy my conversion kit for 250 everything but ecu

is there a way i can get away from the hondata and run a program that id be able to tune myself ??
ecu doesnt really need a tune just want to disable a few sensors..
and change the rev limiter and vtec engagement point....

If you get a EPROM programmer (which you also would need for Hondata tuning) then you can use a freeware tuning program. It's the same process that you would need for Hondata, make your tuning changes and program a chip to plug into the ECU. Hondata just adds a few lines of code to the program so that the ECU looks for the Hondata board. This way you have to buy a Hondata board to use the Hondata software. It's the same thing as Windows software needing a USB or serial port dongle for copyright protection, like CAD programs, etc. Simple and they get their money. The freeware programs dont' have that, but they make the same changes to the stock code that you need to tune.

Dont mess with the setting unless you know what you are doing.... I have been in this game for so long and have attempted many things... but I have never had the guts to actually mess with tuning.... I like my set-up too much.... not worth the risk.... I leave the tuning aspect to the pros...

Amen.

Honestly with the advancements made in the obd1 honda world i wouldn't mess with any obd0 stuff. The programs just arent as well developed. Switch to obd1 imo.

Are you talking about OBD0 tuning programs, or the ECU program?
