Dumb Ecu Question
1. Is A Viggen Ecu Diffrent Then A Ho 9- Se?
2. If It Is What Other Mods Should The Car Have Before The Ecu Is Swaped?
3. Does It Matter That The Viggen Ecu Is Of Course A Stick And Is Going Into A Auto 9-3 Ho>

4.does The Ecu Have To Be Matted To The Car Or Jsut A Direct Swap.

1. Yes, they are different.
2. The major differences between a 9-3 HOT and a Viggen is the extra .3 liters the Viggen engine has. There maybe some other small differences as well.
3. No, there is no difference for a auto or a 5 speed ECU.
4. Yes. The ECU needs to be married to the car via a Tech II.

You will want to have the ECU reflashed with 9-3 SE software. It will run, but not correctly. Like mentioned the extra .3 liters will cause problems with A/F ratios.

Long and short is you cant run the Viggen ECU on the 9-3 Se Hot and have it run right.
