rapid flashing ses

[Daniel E. Griffin]

Got my pocket programmer a couple weeks ago and just burned my first chip 
ever the other day.. Made a duplicate of the original just to see if it 
would work and it did!..Truck actually ran slightly better, (wierd)..
Using winbin I made one change (Bruce's recommendation) and burned another, 
installed it, and ses light began flashing rapidly with key in on 
position..chip wasent reversed position in the zif socket..and ecm was 
unplugged when I installed the chip..re-installed the duplicate I copied and 
no flashing ses light,  so Im stumped..  Bad checksum? ... winbin does the 
checksum for you, right?....  or software incompatibility issue with winbin 
747 settings  to my 165?  others on the list have tuned 165's with winbin, 
right?  my trucks an 88 tech 4 cyl, 165 ecm, bcc amjw 8486,...thanks for any 
help, more questions forthcoming im sure....  dan
