its saabs "state of the art"., now replaced by the trionic 8, computer program for the car. The Trionic 7 was first used in 1999 in the Viggen and the Aero. The rest of the cars were Trionic 5 still. In 2000 all they cars switched to Trionic 7. Today the 9-3 SS uses the Trionic 8, and im not sure but i think the 9-5's use T7 still. Anyway the T7 uses a Mass Airflor Sensor which makes most of the aftermarket parts different such as air intake, and Blow off Valves. The T7 also has two oxygen sensors in the exhaust so you need a catylitic converter. The T7 can also affectivly limit the power of the engine.....it somehow measures torque and limits the Viggen to 230 claimed hp. The viggen really puts down close to 220 whp, which is almost 250 hp. thats besides the point....the viggen is still limited and the engine will create differnent max boosts to make the desired "230 hp". Generally the thinner or hotter the air gets, the higher the boost is set.

Actually any car built in 96 and after, received 2 O2 sensors. This was in order to become OBD 2 ( On Board Diagnostic) compliant. O2 Sensor simulaters are available. But I am not sure what would work on a Saab. This would help if you decide to ditch the Catylitic converter. I have a 95 so no sensor mods were needed.

Check the engine type:

Key to the table:

B= Gasoline Engine (Bensin in Swedish)
D= Diesel Engine (not common in the US)
20= 2,0 litre
23= 2,3 litre
4= Generation 3 engine (Trionic 5)
5= Generation 4 engine (Trionic 7)
E= LPT
L= HOT
R= "extra" HOT, Aero

Example: B235R= Gas, 2,3 l, Gen4, Aero

Turbos used are T25M and GT17 by Garret and TD04 by Mitsubishi

The table below is for Swedish cars, but should be valid for US too.

Car Year Engine HP Turbo
900 94-98 B204L 185 hp T25M
9-3 98.5-99 B204E 154 hp T25M
9-3 98.5-99 B204L 185 hp T25M
9-3 99 B204R 200 hp T25M (modified wastegate)
9-3 (Viggen) 99 B235R 225 hp TD04HL-15T
9-3 00- B205L 185 hp GT17
9-3 (Aero) 00- B205R 205 hp TD04HL-15T
9-3 (Viggen) 00 B235R 230 hp TD04HL-15T
9-5 98- B205E 150 hp GT17
9-5 (Saab trim kit) 98- B205E 190 hp GT17
9-5 98- B235E 170 hp GT17
9-5 (?) 98,5- B308E 200 hp GT15 (V6 engine with assymetric turbo)

If your Saab DI (direct ignition) cassette is red, it is a Trionic 5. If it is black, it is a Trionic 7. DI cassette is where you find your spark plugs between the valve cover.
