On monday me and Rune are visiting Maptun Performance in Örebro to have a lot fun stuff mounted to my 9-5 Griffin.

The visit will last the whole day and a bit more and we’ve planned to do a lot of video interviews with some of the guys at Maptun asking all kinds of difficult questions.

On the list of things we want to find out more about, is how do they work and what is the difference between different types of: turbos, intercoolers, clutches, gear-boxs, suspension, fuel-pumps and brakes. We’re also going to get a big briefing on how to actually tune cars and how software for cars is created.

Depending a bit on the time available we’re also going to show how you install, what’s important to think about, of what I think is the most important product Maptun has, their brake-system.

It’s no understatement that say that most of the guys working at Maptun are pure experts at engines and Saabs in general. Having worked with Saabs and engines for many, many years and having guys like P-A Johansson who actually built a 1000+ hp Saab 9-3 on the payroll presents the opportunity to find out things about engines and Saabs that we’ve always wanted to know.

SO, WHAT DO YOU WANT TO KNOW? Post a question in the comments or send it to our CREW E-MAIL and we’ll do our very best to have as many of them answered as time permits.

  1. The 2.0 TTiD engine seems to be the same as the opels 2.0 twin turbo. Is there any differences?
    I’ve never seen a tuning kit for the saab engine( any serious tunkng Company anyway). But I guess tuning opels engine is on the market somewhere?

    My TTiD seems to need a little bit more fuel than what saab said it would need according to tje manual and the official numbers when the car was released

  2. My question: For petrol engines, all kinds of tuning measures are available. For Diesel engines, tuning seems to be strictly limited to firmware tuning. Why ?

  3. Does MapTun plan to offer any tuning options for the NG9-5?

    Right now only Hirsch tune is available.

  4. Normally in life you don’t get something without there being a cost. I’ve heard that the penalty for a tuning upgrade is a lower life expectancy for the engine. I would like to ask if there any evidence that is the case and if so what is their qualitative expectation of by how much a diesel engine’s life may be shortened by an upgrade. (This may be a little sensitive for them, so you might have to ask it in a slightly roundabout way.)

    Note: Of course, this must be the case or why else did the Saab engineers not design for a more powerful engine in the first place?

    • If you are interested in my SportSedan 9-3 2009 petrol 1,8 150hp turbo Automatic gearbox was Maptuned to Stage 1 at around 60K km. I drive a lot mostly in Russia and a bit abroad. At the moment the mileage is more than 175K km without any problem even little. Considering that Russian petrol is not so chemically perfect like in Europe and there are a lot of cold starts in winter at minus 20 Celsius and more.

      • Unfortunately, any reduced life expectancy is to be expected at the end of life, by definition :-)
        So, if the standard life expectancy is e.g. 330000 km (which is what I am now approaching with my untuned 2.2 TiD), a 10 % reduction would mean end-of-life at 300000. So, you just can’t tell at 175000.

        That is the same problem as with warranties. All good and well, but even Hirsch won’t give me a warranties of even 250000 km.

  5. Maptun has high torque clutches for the high power upgrade of your Saab, but what should you do if you have an automatic transmission?

  6. About Maptun products and really happy costumer with a MY03 9-3ss with custom Stage4+. First thanks to them for the great job and suèrb service.

    I am waiting for news about interior products like leather/nappa or similar dashboard, decor trim in metallic finish or other new products.

    About tuning the car?? Well any new products expected in general?

    What’s the difference and brand of the new performance clutch? compared to the SPEC one?

    What about the quality of the brake kit compared to brands like AP Racing, Brembo? why not looking to perform and adapt one of those?

    About B207 engine, compared to the B205, what do you thing are the strong points for everyone and weakpoints? And the B207 compared to the original version from GM/Lotus and the Opel one?

  7. Does the stage 1 tune for the 2008 9-3 SS 2.0T improve gas mileage and how much?

  8. What are the best options and where to being to improve the chassis response of the 9-3ss My2003, with Aero suspension kit?

    Also in my case, for example to improve the response of the turbo?
