So I was skimming through Wolf's ECU info page.. And decided to see what my SR20DET/ECU came from..

Well, It's not in the list.. I've doublechecked the ECU numbers, but something isn't right...

Whats on the ecu:Big stamped "63"Little red tag on the plug edge:G91Square red NISSAN tag on the cover:A11-000-G91 2X1923710-60F10

Any ideas, gurus?

Ok, found out what it is from:

rs13 jan'91 ~ jan'94 sr20det, automatics13 jan'91 ~ oct'93 sr20det, automatic

Think this may be why I am also having the throttle tip-in hesitation, beings I have a manual trans? Is there a power/mapping difference between manual/auto trans ecu's?
