Calibrating Turbocharger

Hi Malcolm.

Your car has Saab's Trionic enginemanagement. This is one of the worlds most advanced engine control systems. It's an adaptive systems, which means it constantly "learns/reads" the driving conditions: Air temp (and moisture), hills/mountains, speed a.s.o.

If you for whatever reason disconnect the battery, the Trionic will reset to standard values. Once you start driving again, the Trionic needs to learn the driving conditions at new. This takes som time, where you might experince decreased performance. You can speed up the process, by doing as mentioned.

Do you get it?

Henrik,

You said you had a lot of Saab videos? How are they coming?

When can you get them to us?

Hi Henrik,,

I am still bewildered.

What does it have to "learn" that is not pre-set at the factory?

By the way , do you have any idea as to what speed the auto will be at during a full throttle down hill 5th gear 3500 revs run?

Thanks

Malcolm

There's a lot of variables that can't be fully known by the factoy setup. i.e. type of fuel, tolerances in injector flow-rates and fuel-pressure, different exhaust fitments etc. etc.

The idea of using a hill is to keep the speed down. You drive up it, not down it.

Cheers,

Colin.

Nothing done yet.

When I get around to do it. ;o)

Another thing to learn is how you drive can be different than how others drive, where you accellerate/decellerate will be wildly different from your next door neighbor, wife, best friend, etc. It's unfortunate that there isn't some sort of NVRAM that will hold this information with a 9v battery or something to keep it from being lost every time the battery gets d/c'd.

Still it seems to me that doing anything other than driving normally would defeat the purpose of this feature. If it's intended to adapt to the way you drive, then drive and let it adapt. I don't see the logic in fooling it by driving differently initially.

Henrik,

What Saab videos do you have?

Also, will they compliment what is on

It's been a few months now, that's why I ask.

Ah, but you probably only need the 9V battery! I've seen cigar lighter plugs with a 9V battery on a pigtail. You plug it in before removing your car battery and it keeps the computer memory alive. That's the theory, at least. Porsche owners use them to preserve the Bosch adaptive settings in their cars. Might work with the Saab system, too, if 9v is enough. Simple enough to rig up with some cheap parts and a

Turubo

You want a diode in there too, otherwise the 12v car battery will be trying to charge the 9v and that can lead to leakage or rupture.
