ok i have a pocket programmer and im trying to program a 27c128,the =
software=20
keeps telling me that it cant program it.i have tried abou t5 different=20
27c128 and no go,so i tried to change the settings on the pocket =
programer=20
to a 27c256 and it programs it.the problem is i only have one of these =20
ecu's and im not trying to fry it.

the first question is does any one that the same problem with there=20
programer?

the next one is can i use a 27c256 eprom in a ecu that has a 27c128 in =
it=20
from the factory. my understanding it that the last three numbers are =
the=20
amount of memory it has .if so i would think i could use a chip with =
more=20
memory.
well im pretty good at tuning cars but i have no clue when i run into a=20
problem of such.if any one has a clue please let me know,or point me in =
the=20
right way atlest

thank you don freichels

Hallo,

You can use a 27C256 if You have problems to program a 27C128. The only =
thing You have to do is double Your software to fill a 27C256, because =
the processor will read in the second part of the 27C256 (adress 4000 to =
7FFF) instead of 27C128 (adress 0000 to 3FFF). The ECU will work with =
the 27C256.
