R32 gtst sluggsh when cold

I think that funny kick is when the computer goes into closed loop and puts in more fuel. From what I remember the car runs too lean when its cold. When you have a look at the fuel map on the eprom in the computer some of the lower load/rpm points are set a 15:1 theorrticle afr.

Must have been set up to help for emissions in Japan.

Well that my best guess yet anyway.

I'm sure mines the opposite and runs really rich for the first 4 minutes or so then the ECU goes closed loop and leans out. I guess maybe advancing the timing a smidgen should help out & an ECU reset isnt a bad idea.

Possibly. I suppose the best way to tell would be to stick a wide band af meter on the car and see what its doing when cold.

Might just do that sometime.
