Are these the right chips?

[dyerkes]

Can anyone verify that these ECU chip numbers are from a 1987 911 Carrera (227 355 544) and (2 287 356 487)?

Thanks,
David

How many pins? 24 or 28?

Is there a sticker with a stock ECU #? http://members.rennlist.com/messinwith911s/DMEHacking.htm

I reference an 87 North American DME to use 1267355.330 (Clubsport), and 1267355.358. European DMEs for 87 include 1267355.330 (Clubsport). 1267355.357, 1267355.358. All appear to be 28 pin. This may not be a complete list.
