ECU swap - 98 GT into 96 GT

[Huffer]

The 96 GT requires premium fuel. The 98 GT does not.

Has anyone tried swapping the ECU's 98 to 96 to see if the 96 car will run on 87 octane?

Does anyone have a 96 GT and has it running fine on 87?

I think car's that say you HAVE to run premo are bullshit. I've had several mechanics tell me so, and I know my dad's been running 87 in his 626 that "requires" Premo, and his car runs better on 87 than 91.

Unless you have a modded motor, or a stock Higher-compression motor, I wouldn't bother running premo.

Thanks, but that doesn't answer my question.

That's an interesting question. I want to say with the 98 ECU would make it so you don't have to run 91. Try it out man...

What about reprogramming the ECU that you have?

You can't do that. Not without some $$$. I have a 96 GT I'm in line to buy, just trying to determine what grade of gas you can run safely without pulling timing, or if there's another way around it.
