|Need a copy of ZEMULATORv1.5.3.zip or newer (if it exists). The link Ash gave me from my purchase back in 2007 is dead and doesn't appear to be hosted on his site any more.
I have my key/subkey and tune file, but I believe my Z is stuck at the moment with a blank EPROM emulation after the internal zemulator 3v battery died, causing it to go to an insanely rich and undrivable state. It's been a bit since I've touched the car, as it resides in SC at my parent's house, and I live in Iowa.
In town for the holidays and hoping I can get a copy quickly, so I thought I'd throw something on the forums and send Ash an email.
Feel free to contact via my email - email@example.com
