I have a HPP from my 94 car laying around here. My 95 has different gears in it and I just want to fix it so that my speedo reads correctly. There aren't really any LT1 tuners local to me.

The connector is different, but I know that I could use it with some jumper wires. Does anyone have the pin readouts for these 2 years?

So if I am reading this right it is pin M to pin 9, and pin A to pins 4 and 5. Correct?

 

Bump.

 

That's right.

 

Any reason this isn't working?

 

What's it doing? Is it just not able to connect?

Does the Hypertech pull its power from the diagnostic connector? I would think it would have to be self-powered, because I don't believe the OBD1 diagnostic connector supplies power like the OBD2 port does.

 

I don't ever remember having to use a seperate power cable when I used it on my 94. I plugged it in and turned on the key, and it does nothing at all like it has no power.

 

Nevermind. Pulled apart the Hypertech to find a battery with an experation date of May 2004. It's been a little while since I had use of this. :P

Thanks for the help everyone!

 

LOL, and to think I was going to help you with allowing you to use my 95 cable.

I now use it to program with Tunercat (BTW, that is the way to go).

 

Oh I know thats the way to go. I just don't have a laptop anymore. Sold it when I wrecked the 94. I still have the cables though lol.

Is Tunercat free? I've only used LT1 Edit in the past.
