Calibrating Turbocharger
Malcolm William Mason
I read the following earlier:
"I have a 9-5 aero -01. How do I calibrate the turbo system. With full
throttle for about 20 sec? Between which rpm?"
This was the reply:
"You find a longer steep hill. In 4. or 5. gear, drive with full
throttle in
the range from 2,500 - 3,500 rpm. Do this 3 or 4 times. The adaption
takes
place within 2,750 and 3,250 rpm. You need for the car to stay within
that
rpm-range for at least 4 seconds.
If you do nothing, the adaption will take automatically, but will need a
longer time."
What is being accomplished here? I do not understand what is going on.
would someone please enlighten me.
Oh yes: My Saab 2000 9-5 Aero 115k miles
Thanks to all

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

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.

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 www.saabvideos.com?
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
5-min soldering job.

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.
