So on GTechs Website they talk alot about OBDII Programmed cars, which my 93 isn't. Is there a Gtech Product that would work in a 93 Z28?

I know these things are the most accurate in the world, but for the price they do pretty good. It would be nice to see if little mods made changes and such, which this thing would be able to tell.

 

The original Gtech and other devices like it didn't need anything but power and to ba installed level... Of course they also didn't provide all the dashboard info that the new models do through the OBDII port.

 

I see 5 different models on there site, which would be the newest that doesn't need the OBDII port?

 

It looks like the SS or RR will work for you.

Only the EGS has the OBDII option.

 

Which GTech product are you interested in. I'm using an older Competition model...no flaming please...I use it to practice launches. It only connects to the cigarette lighter, so I don't see how it would even care if you have a OBDI or II car.

 

I wonder if the EGS would be a good option for me for getting a tach and having a temp alarm/other diagnostics in one? I am OBD2, so I am interested here.

As to the OP you can use almost all of g techs for your 93 accept the one I am talking about above.

 

I was thinking of getting a shift light anyway, and this thing has one built into it. If I can find one used I'll probably pick one up.
