Installing USB & AUX in an older Saab

April 21, 2013 in Technical

Getting an older Saab updated with features normally found in newer cars making it more up to date is not a big issue. This weekend I got a USB charger from Belkin that fits almost completely into the power outlet in the dashboard. I also installed an AUX port from CDConnect which is sold by Realcar. Both work perfectly and the sound quality through the aux easily matches that of the CD player!

The best thing about the AUX port is that I can use the original stereo and thus the car doesnt lose its original look. The AUX installation is plug n play, replaces the cd-charger connection and is installed in less than 5 minutes.

The only negative issue with it is that it cant be used unless ignition is on.

How do you tune your car?

April 14, 2013 in MapTun, Technical

A lot of people have asked us about the procedure for tuning a car, they feel unsure of if they can perform it themselves, so we at SU decided to make a movie showing how its done. The procedure is easy and well explained in the instructions, it does differs a bit between models but not in any significant way.

As a nice spring gesture, Maptun now offers SU readers a nice discount on tuning software for your car, please use the promotion code: SU2013, the code is active until sunday April 21st and can only be used at the website www.maptun.com.

SAAB 9-5 Pendulum (Sway bar links)

April 10, 2013 in Technical

Pendelum 5236823In a previous post I talked about the things that are the most important things to replace on a used 9-5 in order to get it back into great shape. I got a question via e-mail if I could show exactly what the pendulum was. I did some digging and found a photo of a car on which we replaced the pendulums.

These things are sold for about 25 Euro’s and the replacement takes about 15 min per side when a experience mechanic does the job. An important upgrade to such a great car! I ordered mine from Maptun Parts (for swedish customers), over there they cost 135 SEK per piece. They are also available from all dealerships selling SAAB genuine parts.

Article number for the part is 5236823.

The procedure for replacing the pendulum is:

  1. Lift the car
  2. remove wheel
  3. remove pendulum (sway bar links)
  4. fasten the new pendulum, with 90 Nm (65 lbf ft) of torque
  5. re-attach the wheel, use 110 Nm (81 lbf ft) torque for ALU wheels.
  6. Done.

What happened to IQon?

March 9, 2013 in Technical

In march 2011 SWAN Saab presented themselves on the Geneva Motor Show as a new company with lots of ideas and new pieces of technology that they wanted to implement in their future cars. For those nostalgic among us, you can review the press conference here.

Jason Castriota showed with the PhoeniX concept car, where the post GM Saab design was heading to. Now, two years later, SaabsUnited is bringing to you the design of the first offspring of that design language. This car will never hit the road, but from the comments on this side on designs that still do not show the final product, my impression is that this car had the potential to help Saab get back on its foot.

One of the technology pieces that would have put Saab back ahead of other companies is the eAAM electric rear axle. From their presentation on the Geneva Motor Show we learned that the Chinese Qoros will be using it but not on its full potential, as we learned that Qoros will not implement torque vectoring in its car. I don’t like the idea of Audi telling the world in 2014 or 2015 that their eQuattro system is the first electric rear axle with torque vectoring, as we know that eAAM could have been today ready for production.

The other piece of technology that Saab demonstrated at the Geneva Motor Show was the IQon infotainment system.

IQon was an Android based infotainment system. It was like the flexibility of a modern Smartphone or tablet combined with the car integration of a legacy infotainment system. Being this such a promising system, what happened to it after the Saab bankruptcy?

What it could have been, the future of the eAAM electric rear axle.

February 17, 2013 in Technical

History is what it is, and we are the last ones being able to change it. Nevertheless it is for me interesting to see what it could have been.

In the winter 2010/11 we were quite impressed by videos like this and this. That was the demonstration of a game changer technology, which was at least two years ahead of the closest competitor, and what was most important for us, Saab fans, that technology was planned to be first seen in a Saab car.

eAWD

This was an electric rear wheel axle, which was able to join fun to drive (torque vectoring) with fuel economy (89 g/km CO2). But months later the SWAN Saab Company entered into financial problems, and we all know what happened after that.

During the bankruptcy administration, AAM bought the Saab part of the e-AAM joint venture and searched for new customers for their system.

I’ve been since then wondering where will we see this system for the first time. Now I know that the first concept using the electric rear axle from AAM will be presented at the Geneva Motor Show.

New rules on emissions will govern new engines

January 28, 2013 in Technical

Hirsch Exhaust 9-5

Saab 9-5 Hirsch Dual Exhaust

Saab’s previous engines the 1,8t and 2,0t used in the 9-3 until 2010 were certified according to Euro 4 and Euro 5 requirements.

The different regulatory bodies in the world are today working on a harmonization system in which more or less the same regulations would be used all over the world, making development of engines much easier and to say the least, cheaper for auto-manufacturers.

About two weeks ago I contacted two sources to find out more about what requirements were in place right now and what a gasoline or diesel engine would have to achieve in terms of emissions compared to what they did before.

What I found out was very interesting. The current legislation currently in force since mid summer 2012 is the Euro 5B+ and in terms of pure emissions there isn’t really any significant difference is values compared to when the above mentioned engines were in use with Saab Automobile AB.

The big difference now is the measuring of certain peak values and that the car should achieve similar values in everyday use as it did during testing. These values should also be available through ODB-readout during maintenance or check-ups. Thus identifying any malfunctions in the catalytic system or engine. Certain peak values are programmed to be observed and reported.

This is however only the first step. Read the rest of this entry →

The difference between real and fake turbos

January 23, 2013 in Technical

P1020408

Click for high-resolution photo (turbo on the left is fake, turbo on the right is genuine)

Yesterday we had an interesting question to the guys working at Maptun Performance from one of our readers. He asked why some turbos cost between 2-300 dollars and the one from Maptun was so expensive? The answer was pretty simple, most often the cheap turbos out on the market are faked copies as Maptun only sell genuine turbos. After a bit of research we’ve even found that some companies sell these faked copies as genuine at the price of a genuine turbo.

Garrett GT1752So how do you know if what you’re buying is the real thing or a copy?. The answer, look for the logo. On all TD04HL Mitsubishi turbo’s which was used by Saab in the high power models of the 9-5 and 9-3, has the Mitsubishi logo on the exhaust housing right next to the beginning of the article number of the turbo, as seen on the turbo on the top (logo 89-11300). The fake copy version on the left does not have a logo but only the article number of the product.

By comparing the fake copy, on the left and the genuine on the right, you’ll also see that the waste-gate is of a much weaker construction than the genuine (right) version which often lead to waste-gate failure and also miss-alignment of the waste-gate compared to what is commanded by the engine management software.

When replacing a turbo with one you’ve bought compare the fan-blades of the compressor as these are normally of a much more rough cut and not as well machined in the copied version compared with the genuine. Reduced performance and failure is fairly common with these copied version, especially on tuned cars.

Garrett GT1752 turbos normally used on all low-pressure turbo engines in Saab has the name GARRETT written on the compressor housing, the copied versions do not have this text but only the type GT1752 written on it. There are many companies selling faked versions of the GT17 which is only natural as its widely used in many brands around the world.

The Saab 900 SuperAero & aerodynamics issues

December 11, 2012 in Saabology, Saabs History, Technical

When designing a car there are dozens of conflicting issues to negotiate. Some wants a super sporty sleek car other a more family practical oriented. For a manufacturer this is a tough issue to deal with especially when You are a small player with a limited number of lines of models and nothing is then allowed to go wrong the cars just have to sell like cupcakes.

Saab started out of an airplane maker with the range of B-17 Dive-bomber, J21 and the jet powered J21R interceptors, so aerodynamics was nothing new. The 92 model was slick for its time but low speed up to its modest top speed of 110km/h was all-fine. The issue is when going faster, when the airstream over some areas of a car body creates lifting power just like what a wing does on a plane and the 92 was more or less across section of a wing. At high speeds the rear part of the body on the 92-93-96 models create lift, this force has a negative impact in the performance on the road. A tuned 96 V4 with an Sonett gear box (high 4 gear) would make that car go 190 km/h, that is not a pleasant experience, rear wheels hardly touches the ground. Read the rest of this entry →

Driving Habits Polls

November 20, 2012 in SaabsUnited Related, Technical

Updated: It’s been a few months, but this info is finally going to come in handy for a new series we’ll be starting next week. If you haven’t already answered, feel free to chime in the poll. Also I’ve added one new poll at the beginning related to how many cars are in your household and where you park your car at night and during the day.

It’s taken a while for us to get here, but finally there’s light at the end of the tunnel and I think it’s time to start exploring the possibilities of what a future at Saab could be. As part of my research for a lengthier piece, I need to conduct a quick poll to see how far the average SU reader commutes to and from work and how far they drive on their days off (or if they don’t drive to a typical stationary job). And who doesn’t love a good poll every now and then? :) Feel free to sound off in comments and explain how far you drive and where you are. This isn’t the time to read into the question yet, that’s for the next post I do shortly after we have results. Thanks!

Dr. Saabish: On the Physics of the Front Strut Brace

August 31, 2012 in Fan Stuff, MapTun, Saabology, Technical, We are many, We are SAAB

Dr. Nio Saabish, Ph.D Physics It’s precisely eight past noon.  Normally any resident of the lecture hall would be submerged in complete darkness, surrounded by rows upon rows of empty seats.  Of course, as one would expect, the auditorium’s regular occupants are hard at work preparing for their upcoming mid-terms.  But tonight: is a special night.  For a room that is typically bathed in sunlight, has found itself illuminated by the soft glow of several banks of fluorescent lights.

Saab ePower ready to roll

June 20, 2012 in Technical

After talking with a friend the other day regarding the Saab 9-3 ePower, he told me a very interesting detail that for some reason I’ve completely missed. The 9-3 ePower research and development was finished by Saab, the car even received its type-certification which means that it is ready for production. 200 cars were ordered as a test fleet. This car not be as far away from customer-launch as I first thought…

Source of noise

June 18, 2012 in Technical

Shortly after I bought my 9-5 SportsCombi in 2010, I started hearing a squealing noise from somewhere in the back of the car. Two different dealers tried to deal with the noise and could not find it, it has been an extremely annoying thing I’ve had to live with, until today.

I’ve tried to empty the car from everything that I’ve put into the car since I bought it on several occasions, today everything went out, even the standard things that could be taken out and when I found out what made the noise, I almost got mad at myself for not finding it earlier, it was after all fairly obvious…

The source of the noise was the storage bay, a piece of add-on located under the floor-board of the baggage-compartment, which was shipped with the car as part of the Griffin-package.

Normally it rests against the metal bars on each side of the baggage-compartment but, if dirt makes its way there and places it self between the metal and plastic, there is noise…

The fix, clean it, put some duct-tape on the metal bars so that the storage-bay rests against that rather than pure metal, noise gone! =)

Stopping on a dime: Part II

June 15, 2012 in Fan Stuff, Saabology, Technical

Just last week, I discussed the awesome braking performance of EBC’s kevlar-ceramic high-performance Green Stuff Brake pads.  These pads truly live up to the hype, as they have a grip hard enough that you can actually feel the disc being clamped beneath your foot.  But, if that is the case, why is it that they are now sitting in a box beneath my desk?

While we are waiting…

June 13, 2012 in Technical

The announcement is finally near after some days of extremely hot discussions. The aim of NEVS to make electrical and hybrid cars was in the center of those discussions so I thought I’d bring up a a few videos of what a Saab hybrid could be. In the end NEVS may be much closer to Saab’s original plans than we all would think.
