Saab does build a car with a similar ECU. They call it the "9-5 Aero". > So what would > the catch be? If Saab did it the catch would be a higher insurance cost, would scare away ordinary customers, would need more expensive brakes and wheels. By using basically the same engine with different software Saab can position the 9-5 models in more market segments. > Fuel consumption? Higher if you use the extra power, obviously. Lower, or unchanged, if you drive as before the new ECU. > Engine life? Shouldn't be a problem. How the engine is treated (oil and filter change etc) is more important for engine life. > Emissions? Shouldn't be different during normal driving. When you use the extra power you will use more fuel, i.e. more CO2, but it should be about the same as emissions from the 9-5 Aero. My 9-5 1999 with 170hp engine has been running with BSR ECU software (230hp/400Nm) since early 2000 without any problems. The change in engine power is very noticeable. -- G–ran Larsson http://www.nospam.com/saab/
