Saab 9000 Aero Manual (or 1998 CSE manual) ECU ECM Engine Control unit, 225HP 4780268  - This is the "red box" of the 9000 world.  This unit, correct for the NON traction control 1994-1998 9000 Aero cars dials up the boost over the CSE models.  With the T25 Turbo this makes around 215HP, with the TD04 turbo (which is correct for manual Aeros) you get the full rather under-rated 225HP.  This unit is super hard to find.  Also of note, 1998 9000 CSE's equipped with the manual transmission are also Aero powered.
