One of my current Saab rescues, is the 2005 9-5 2.3t Vector, I can't deny my fondness for the Smoke Beige Metallic saloon, it's one of my all time favourite Saabs, and there's not many of them around in this condition. Add to that, it's only ever had one owner, it's got a lovely specification, and also low miles, but it had one obvious flaw - not having the higher output Turbo of the Aero.
Alongside various maintenance required, it's also had the larger Mitsubishi TD04 Turbo installed, this immediately takes it to the same engine setup as the standard Aero besides the mapping of the ECU; the standard Vector was 185hp, whilst the standard Aero was 250hp.
However, thanks to the support and generosity of MapTun, Sweden, they sent over one of their clever MapTuner Nano NX3 units, together with their connecting cable for me to try. I've been wanting to try one of their maps for a while now, and this gave me the perfect opportunity. For this particular 9-5, I wanted a subtle remap to enhance, rather than dynamically change its overall driving characteristics; it's an auto gearbox twinned with the Saab lowered performance suspension, so a lovely, comfortable cruiser, the Nano NX3 with the Stage 1 TD04 - 270 Hp/380 Nm map was exactly what the car needed.
Install was as simple as MapTun described, and as long as you have a decent wifi signal near the car when you perform the upgrade, it works flawlessly. I installed the accompanying app on my iPhone, paired that with the NX3, downloaded the relevant TD04 270hp file and prepared the car for the upgrade. We had to disconnect a few fuses turn all electrics off, and keep the battery on charge during the process. Thomas at MapTun was absolutely fantastic at being on hand for a few 'user errors' and advice along the way, but within 45 minutes, the file was installed and the Saab ready to test drive.
Immediate feedback - it felt quick, Stage 1 Aero quick, on acceleration, the new TD004 boosts instantly and the gear change clean and smooth; I never tend to hold the pedal to the floor in the autos, as they react beautifully to steady acceleration, building power through gears, rather than kicking down and screaming.
I've driven the 9-5 for a good 500 miles now, and been hugely impressed with the remap. I will be trying the various diagnostics and readings available on the app in the coming weeks, but wanted to share some initial thoughts. As less and less decent Aeros are available, this is an exceptionally viable way of transforming a Vector 2.3t into an Aero.
Thanks go out to Jason Miles for his endless wisdom on these Saabs, and Thomas at MapTun for his generosity and support. I've been hugely impressed by MapTun and their Saab products, they continue to invest in the research and development of many more products for our Saabs, it's people and companies like MapTun that genuinely make Saab ownership viable, their dedication to the brand is hugely appreciated my myself and many other global owners; please keep going.
