i ran out of 27sf512 chips so i grabbed
the spare 29c256 out of my firebird
it burns just fine 8d code , i can make any
change i need no problem . i try and
burn it for my typhoon using different
programs i have used before and when
i try and use it on the truck it doesn't work ,
check engine fault . when i try and open it
in tuner cat it says ecm definition file
not compatible and i should use $58
which i am using ..

any ideas

You have to load the $58 code in the upper half, or double load it.
It only uses a 128K image.

so you are saying i need to change
the device end point on a 29c256
chip ? if so where do i end it at ?

Set start of device to 4000, end of device to 7FFF.

How do you run out of 27sf512 chips? They should be good for 10,000+ re-writes. You can bin stack using the MS-DOS "copy /b" command. It does a binary copy.

i tune on several different vehicles for
friends . i need to order some more
chips . i do have some 29c256 120ns
chips i wish i could use with my pocket
programmer but it does not recognize them .

thanxs craig for the info

so i neeed to fill the buffer with FF at all locations
to erase it and then start the program at 4000
to work

the wrong buttons .

not compatible with this source file ,use
$58 definition file .

i already have $58 chosen as my ecm in
in tunercat .

The Pocket Programmer will recognize the AT29C256 chips. I was programming some with a PP the other day. I think it is the "F" key for flash and then the "8" key for AT29C256. The PP has supported them for a long time. Did you put them in the socket correctly?

turbotater

yup its in right
i went and put my firebird 8d program
back on it and it worked just fine
i made some changes and it works in the car
and i can read it correctly in tuner cat .

i am just having some wierd issue
tryin to put the $58 stuff on it
