Can the stock eprom chip be reprogrammed? (with the right hard/softwares)

[G_Match]

or is it a one time flash only?

How about a giac chip? can it be erased/rewritten?

Or does one need a blank chip to write a custom file? if so where can i buy blank eprom chips?

this is for 98 aeb so no 'flashing' possible..

thanks

Unitronic flash loaded my 557P ecu in my 1998.5 A4. I'm 100% positive they can tune your car.
Call 'em up 1.866.341.2447 At least that's the number we can use in the U.S., Australia I'm sure is different.

To answer your question directly, yes the "eprom" can be rewritten.
I haven't heard it called that in awhile.
AFIAK APR, Unitronic, and a couple others flashload.
