SR20DET ecu questions
 

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:
G91
Square red NISSAN tag on the cover:
A11-000-G91 2X19
23710-50F10

So searching more, I found that it is from:

rs13 jan'91 ~ jan'94 sr20det, automatic
s13 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?
