Memcal Help

[Burt_vn]

Hey guys, sorry i know i have read on here somewhere a listing of the memcals and that the s2 vn tune was crap and the s1 vn tune was good.. I just pulled the memcal out of my spare ecu..
Do i need to take anything apart to find the serial number that you guys will recognize? there is a serial number inside - ATJR4357.. this ecu had been checked by an EFI place in 2000 (according to the sticker on there) im just trying to figure out what tune this memcal is..so if anyone has the serials for the vns or any help thatd be great

Sorry to be the noob, but i had to do it at least once :P

found on doctor bobs site www.memcals.com
