FAQs

Q?

What type of oil should I run in my car?

A.

We typically recommend Shell Rotella T6, 5w-40.

Q?

What is a Wideband O2 Sensor?

A.

A Wideband O2 sensor is an Oxygen sensor. Your Saab has two oxygen sensor stock, but these are narrowband sensors, which are good only to verify rich or lean compared to stoichiometric ratio (14.7:1). A Wideband O2 sensor will accurately read actual air to fuel ratio based on spent gases.

If you choose to run wideband setup in your car, we can accommodate that in an ECU Upgrade. We can wire the sensor directly into the ECU for data logging purposes. We can then use that data at a later point to further fine tune your fuel maps in a custom ECU Upgrade.

Q?

Why is my car misfiring?

A.

For the 2003+ 9-3SS/SC/CV misfiring under high load is a common problem for these tuned Saabs. The issues is likely due to coils. You can try gapping the spark plugs down first and it may help a bit. We shoot for 0.9-1.0mm gap on these cars.

 Also check your coils, if they are the white top coils those are more prone to this misfire. If the misfires continue after you have reduced the spark plug gaps, then you will want to look at getting some coils.

Q?

Adaptation runs?

A.

Adaption will happen naturally during your day to day driving. The best way to do it is to maintain a high load (wide open throttle while driving uphill if possible), while in 4th gear (3rd is ok too), from RPMs of 2000-4500rpm. During this process you won't get any confirmation from the car that the adaption is completed, and you aren't going to notice anything feeling different either.

If your boost tables are already mapped correctly, then the boost Adaption result would be zero. However there are car to car variances and the differences in hardware that are accounted for in this adaption. You can relate this adaption to the feeling of gaining a bit more power when you reset your ECU.

Q?

Why Upgrade my intercooler?

A.

The reason for upgrading the intercooler (IC) is not to make more power but to be able to consistently make the same power over and over. With your stock IC and an ECU Upgrade, you will maybe get one or two hard pulls before the car starts to heatsoak. Heatsoak is when your intake temps get too hot. When intake temps get too hot the car will be susceptible to detonation. And now that the air is hotter, it’s also less dense. This results in the engine needing even more super-heated air to make the same power. Your ECU will do things to counteract this like pull ignition timing to reduce the risk of detonation. It will also begin to pull boost and limit power as a safeguard. So by upgrading the intercooler, you will keep intake temps in check and you will be able to make the same power pull after pull after pull. Whether or not you actually think you should get an upgraded IC is up to how you drive. If you are balls out all the time, wringing the car out at every chance you get, then an upgraded IC is what you will need. If you’re only doing a hard pull here and there, then the stock IC will suffice. And if you’re on the fence about it, then see how things go after the ECU upgrade. Next to a downpipe, an upgraded IC is the next best hardware purchase.

Q?

Can BCB enable the audio aux port?

A.

We cannot set this up with an ECU Upgrade, you will need to see a dealer to have this enabled.

Q?

What do these different Stages mean?

A.

Brew City Boost ECU Upgrade Stages refer to the level of performance upgrades to your car. Most people have their own interpretation on what the Stage levels mean, and of course we do too. Even our stage levels vary a bit based on the car model.

Our stage levels are broken up like this:

Stage 0

Stock vehicle

Stage 1

An ECU Upgrade on an otherwise stock vehicle

Stage 2

The vehicle has been upgraded with a freer flowing intake and / or cat-back exhaust system in combination with an ECU Upgrade. An upgraded intercooler may also fit into a stage 2.

Stage 3

The vehicle has been upgraded with a freer flowing intake or exhaust system in combination with an ECU Upgrade and a 3” turbo downpipe. This may also include an upgraded (higher flow) intercooler, full 3” exhaust system, and / or upgraded fuel pressure regulator.

Custom Stage

This all depends on the vehicle and what your power goals are. We will design an ECU upgrade that maximizes performance based on your exact modifications. Custom tuning is available for when you want to go big and start upgrading items like your Turbo and Fuel Injectors. In addition we can also offer Custom Live Tuning where available, just contact us for details.

Please see our ECU Upgrades pages for the stage descriptions by model and their resulting performance gains.

 

Q?

How do I find my VIN and Immobilizer code?

A.

Your VIN is on a tag on the driver’s door jam, and the Immobilizer code is on the ECU itself. Please visit our “HOW TOs” page for detailed instructions on removing your ECU, and getting your Immobilizer code.

Q?

Will I notice a difference in driveability?

A.

Once your ECU Upgrade is installed, your car will be an absolute pleasure to drive, with much more smooth and very crisp, usable power delivery throughout the RPM range. This improves drivability in the city, on the highway, and in the twisties.

Q?

Shipping process, turnaround time, shipping cost, and international shipments of ECU upgrades?

A.

When you purchase and ECU Upgrade we typically can have it processed within 1-3 days
of receiving payment. We typically ship our items on Mondays, Wednesdays, and Fridays.

For other items, multiple item orders

  Our products are carefully chosen from outside vendors so a multi-item order may ship in separate packages / shipments. Note that some of our items are drop-shipped from manufacturers.

  Shipping outside the US may take longer due to customs paperwork.

Q?

What is the core exchange process?

A.

We offer optional Core ECUs to make upgrading more convenient for our customers. If you choose this option we will ship you an Upgraded ECU, this minimizes downtime of your car. Then you install the upgraded ECU, and ship us your original ECU within two weeks for a full refund of the core amount.

If you decide not to purchase a core, you will need to send us your ECU for Upgrading.

The core ECU option is really best suited for the T5 and T7 upgrades, because for those units, we can send out a preprogrammed ECU directly to the customer. Then they simply return their stock ECU and get the core refund. This is intended to reduce the downtime of people's cars. We are no longer offering T8 cores.

Q?

How do you accept payments?

A.

Currently we accept credit card and paypal payments. If you would like to use paypal send the payment to orders@brewcityboost.com.

Q?

Could an ECU upgrade have any negative affect on my car?

A.

In most all cases an ECU upgrade will have no negative affect on a properly running and well maintained car. If your car were to have (for example) a vacuum leak prior to the ECU Upgrade, it will probably be more noticeable after the upgrade. If you have any weak or marginal components they may fail sooner under the increased power output with an ECU Upgrade. Our advice is to always ensure your car is in proper working order prior to an ECU Upgrade. If you are unsure if your car is suitable for an upgrade please take it to a professional for inspection prior to the upgrade.

Q?

Will an ECU Upgrade improve my MPG?

A.

This is a very common question. Brew City Boost ECU Upgrades are designed for maximum performance, not for fuel economy. That being said combustion efficiency is optimized in our upgrades and our customers typically report a 2-3 MPG increase.

Remember that MPG is also greatly dependent on driving style. And once you start dramatically increasing yours engine’s horsepower and torque with an ECU Upgrade, your car will be a lot more fun to drive. So if you are like us, you might just find yourself pushing your car a bit harder because…..well, you just can’t help yourself!

So if you can “be good” behind the wheel, you’ll likely see a slight increase in MPG.

Q?

What type of fuel should I use?

A.

We recommend premium fuel, 93 or 91 octane minimum, when running our tunes. Your car will still run and not have any issues on regular fuel, but you will experience reduced performance. The ECU for T8 cars has 3 separate ignition tables that we map for, one for 93, 91, and 89 octane fuels. This is done to compensate for those different octanes’s detonation resistance.

You will likely also see an increase in economy when running premium vs regular, enough to maybe make the choice to run regular over premium a wash. Besides, a tank of premium is typically just a few dollars more and your Saab will thank you for it.

Q?

Will my (auto) transmission shift points change?

A.

No, those will not change. We do limit torque in first gear to help make the added power more “drivable”, otherwise you will just spin your wheels.
