What is out their for obd1's?

The dumpster, LOL
Okay, that was a joke, you gotta work with me here.
You mean in the way of code reading or tuning or what specifically.

code reading for obd1.5 mostly
What can i get to tune it

I believe, and dont quote me, that most of your garden variety code readers out there will work on ODB I. They will state on the package and many of those you can get for under $100.
As for tuning an ODB I, that I have no clue about. Hopefully someone with more insight than I in that area will step in and let you know.

Reading OBD-I codes was easy. Just jam the paperclip into the diag port and watch the SES light blink. OBD-1.5 was the bastard child of GM. I've not seen many code readers that would touch it, especially 1994 +/- a year. OBD-II+ can be read easily by any of the available over-the-counter units. Most programming for the OBD-I/1.5 stuff was done with EEPROM burning, right?

but i do believe that eeproms/chips must be employed for any sort of 'tuning'

Man, it has indeed been a long time since I had to mess with any of that, I forgot all about the EEPROMS. Ive never dealt with ODB-1.5 or really knew about it for that matter.

I'd check out TunerPro. Its free for the software and I believe should work for you since you have a 95. TunerPro and TunerPro RT - Professional Automobile Tuning Software (<--- Click that, doesn't show up as a link with the new skin)
In the definitions, you'd need the $1FA bin file.

I believe the reason GM came out with OBD-II was because they had to many problems with OBD-I not and the cost of having to replace PCMs with problems. Because OBD-I PCMs where like CD-Rs write once. This was killing them so they came up with the new memory to allow PCMs to be reflashed by dealerships.

Nope there is a site were you can download tunning software its called tuner cat and they go all the way up to 96 so check that out and see what happens
02-01-2008
ummm no. sorry. OBDII isnt a GM thing, it's an auto industry thing. It's just more advanced logic system, allowing for better engine management. the programmable PCM's just come along for the ride.

And now, of course they have went to CAN.

Where do I get the cord to plug into the car?

I'd suggest you check out their forums there. The tuning on OBD1 is a little different bc you need to be able to burn an PROM. THe standard PROM is not usually an EEPROM (Electronically eraseable PROM). In order to do your scanning and such, you need basically just any ALDL connector you can get from ebay or any number of links. (TunerPro and TunerPro RT - Professional Automobile Tuning Software)
You could look into the "Romulator" which lets you emulate your standard PROM and then make changes and such on the fly. Its a bit more involved but it would be sweet.

Tuner Cats is a very good program! I used that for tuning on the LT1 then switched to LT1 edit.
