obd0/obd1 ecu socket/chippers...i have a quick question...dr disco
i stumbled across a box of chips and i think they are compatible with these ecus but i want to make sure. they read as follows:
part number M27C64A
-15F1
B880A
0148L
singapore
they are 28 pin and look exactly like the zif chips we all use. thanks.

The 64 in the part number stands for 64kb, which is the capacity of the chip. This is too small to store the rom, which is 32kB, which is equal to 256kb. Therefore, you need a chip of at least 256kb capacity, a 512kb will also work. The other important piece of info is the -15F1. The 15 indicates 150ns response of the chip. To work reliably, the chips must be 200ns or faster, which is indicated by a -20 or lower.
