I’ve got a list as long as your arm of things I’d like to do with the Viggen one day. I have a trip to Sweden to pay off first, though.
One of the things I’ll be doing eventually is uprating the ECU. It is without a doubt the biggest bang-for-the-buck upgrade you can do and with a number of tuners providing tuning upgrades for Saabs it’s not something that’s out of reach or hard to source.
I got this email in over the weekend from Simon A, here in Australia. He’s gone with the BSR option, which is quite an attractive one due to its simplicity. Many ECU upgrades involve an exchange of the unit – yours out of the car and the new one into the car. The BSR upgrade is plug-n-play. The software comes in a unit that you simply plug in to your Saab. It takes a short time to download and you’re away…..somewhat faster than you were before. To restore your previous factory spec, just plug it in again and it reverses the upgrade.
Here’s Simon’s email to me:
This morning I became the proud owner of a BSR Stage 1 PPC Upgrade for my MY98 9-5 lpt. While only having owned this for no more than 8 hours, I already have a few points to make about this little treat.
For starters… WOW!
I’ve always found the lpt impressive for its fairly low power (170BHP/125Kw) and have always loved the way it can pass much more powerful cars in the overtaking lane thanks to its useful 280Nm. The Stage 1 upgrade lends my little motor a whole swag of extra power to bring it to 234BHP/175Kw and a mountainous 380Nm. The change in incredible! Where is was capable before, now it’s just plain fast. I’m now loving the power that Aero owners take for granted. I’m also loving the fact that in 3rd gear it can stomp on a friends SS Commodore! I’ve never seen the speedo move like that before…
For owners of lpt 9-5’s, this is a must-have. I can promise you it will be the best ~$1200 you’ve ever spent on your car (until asking for an extra 30% from your 10yo engine takes it’s toll!).
That last point’s an important one. Prior to warming up your Saab you should always make sure that the rest of the car is at least running well in standard spec. Cars are engineered a certain way and when more is asked of them, well sometimes something’s got to give. Talk to your tuner about other upgrades that might be advisable for your model so that your car remains balanced and reliable.
For me, for example, the Viggen really needs some steering and suspension upgrades prior to adding any more power. The rest of the car’s breathing and cooling apparatus could probably benefit from some uprating, too.
If you’re ready for it though, the ECU is one thing that’ll give you instant fun.
