Base Boost Setting/Wastegate Leakage
Introduction The APC system used on all full-pressure Saab Turbos although implemented in at least three different ways over the years controls the turbo boost pressure above a certain level known as basic boost or base boost.
This level of boost is set mechanically by the wastegate actuator on the turbo and should be set to a prarticular pressure, depending on the model. This procedure shows how to saab 9 3 base boost and adjust the base boost pressure. Each adjustment requires only a few minutes. However, if further adjustment is required, the engine must be allowed to cool sufficiently to touch. From my experience, this typically takes a few hours.
These were the tools I found necessary for the TD04 on my manual '96 Aero. Other turbo installations may require different tools. The various parts mentioned in this procedure are shown below Aero with Mitsubishi TD04 turbo shown: If the basic boost pressure adjustment has been completely lost, for example the wastegate actuator or turbocharger has been dismantled or replaced, an initial setting may be set as follows: Perform this operation with the engine cold. Saab 9 3 base boost a few seconds of running can make the turbocharger too hot to touch.
It is best to do this while parked on a hard, even surface e. These are the specifications I have been able to find so far. If your car is not listed here and you know what the basic boost pressure should be, I would be happy to hear from you.
I'm especially curious about the specification for the rarer, higher-powered s such as the CS Turbo S and the Carlssons. General Jacking and axle-stand points.

Search Saab Time required Each adjustment requires only a few minutes. Tools required N. Spanners 10mm or 11mm, depending on model Other Boost gauge A boost gauge is essential for measuring the base boost level.
There is no other way. The more accurate and precise the better, but I get good enough results from a gauge that is not very precise I reckon I can resolve to within 0. A gauge with a range of around 0. This is what I use. While this is not very precise due to the small scale and large range, I have used it to measure base boost. It is better suited to measurement of peak boost. This gauge is designed to be mounted inside the car, but I only use it for adjustment so I don't have it permanently mounted.
Procedure The various parts mentioned in this procedure are shown styl warszawskich ulic skype Aero with Mitsubishi TD04 turbo shown: If the basic boost pressure has been lost completely If the basic boost pressure adjustment has been completely la tierra cerca de martens, for example the wastegate actuator or turbocharger has been dismantled or replaced, an initial setting may be set as follows: If necessary, jack up the front of the car and support it on axle stands.
Slacken the locknut on the wastegate actuator rod. Remove the circlip or spring saab 9 3 base boost retaining the rod end on the wastegate lever and unhook saab 9 3 base boost rod end from the pivot on the lever.
Unscrew the rod end until the hole in the rod end just slips over the games android 4.0, with the wastegate held in the closed position. Screw the rod end back in by 3. This will pre-stress behnein drama episode dailymotion er actuator by approximately 3mm when the wastegate is closed.
Refit the rod to the wastegate and refit the retaining clip. Measure the basic boost pressure as described below and adjust if necessary. Measuring the basic boost pressure Connect a boost gauge to the car. My '96 Aero has a vacuum takeoff point for just this purpose situated on the inlet manifold. It is normally blocked off by the rubber plug seen in the foreground. Other models may require the insertion of a tee-piece supplied with the TIM gauge in one of the vacuum lines. Do not connect to the PCV hose on top of the cam cover with a white plastic valve halfway along it.
On non-Trionic cars: On non-Trionic cars, disconnect the electrical connector on the APC solenoid valve. This is mounted on top of the radiator on the left side of the car battery side. It has an electrical connector and three rubber hoses connected to it. Don't disconnect the hoses. I don't have a photo of the non-Trionic style of valve. If anyone can supply a photo showing the valve and its location, I will be very grateful.
Take the car for a test drive and with the engine at normal operating temperature, do some hard accelerating. A saab 9 3 base boost hill can help here. Note the maximum boost pressure indicated on the gauge. On Trionic cars and LPT models: Take the car for a test drive and with the engine at normal operating temperature, select third gear manual or automatic and accelerate at full throttle from below Saab 9 3 base boost avoid the kickdown on models with automatic transmission.
As the engine speed approaches RPM, press the brake while holding the accelerator, to achieve full load at RPM pressing the brake pedal also causes Trionic to drop the boost pressure to base boost on non-LPT models.
Note the pressure on the gauge. If the basic boost pressure is not within the specificationadjust it as described below and repeat the measurement. Adjusting the basic boost pressure N. Holding the wastegate actuator rod near the threaded end with a pair of pliers, slacken the locknut using a 10mm or 11mm spanner. It is important not to hold the rod near the wastegate actuator the round can as any slight damage to the rod in lagu jones mekitarista area can cause the rod to bind in the actuator.
Remove the circlip or "R" clip retaining the rod end on the wastegate lever pivot. Screw the end piece in shorten the rod to increase boost pressure or out lengthen the rod to reduce it.
See the specification for the approximate relationship between number of turns and pressure adjustment. Best performance will be achieved by adjusting towards the upper end of the specification. However, exceeding the specification can cause problems, including the risk of engine damage in adverse conditions. Replace the rod end on the wastegate pivot and refit the retaining clip. Note that on my Aero, the hole in the pivot for the "R" clip is vertical and it would be much easier to insert the saab 9 3 base boost from underneath than from above.
However, it would then also be much easier for the clip to fall out. I have become practised at inserting the clip from above. Once again holding the rod with a pair of pliers near the threaded end, tighten the locknut.
Measure the basic boost pressure using the method described above. If necessary, allow the engine to cool and repeat the adjustment. Basic saab 9 3 base boost specification for various s Note: Model Basic boost pressure Approx.

The "hole" from the "arm" of the wastegate-actuator has to be installed with a loose fit to the arm of the wastegate. The car is running fine, but somehow i dislike it; especially, becouse the WIS tells me, to install the saab 9 3 base boost pre-stressed. Now my question: Is it possible to tell the ECU saab 9 3 base boost, that the base boost is 0.
Thnaks a lot! But I think it doesn't matter much if actuator has 0,4 or 0,5 bar baseboost. Set a little pretension to the forge and check what baseboost it gives. Adjusted with the values, I can see on CarPC The max boost was not stable, it was "pumping", always producing a slight overboost to fall again, about one time per second.
Adjusted to exactly 0,4 bar, the boost is perfectly stable. So I think it is an issue with the software, what it expects base boost to be. It's set to produce a 0. The stage 3 saab 9 3 base boost boost is totally stable.
I think you might have for example something like a stuck exhaust pipe if the actuator is correctly setup with pre-stressing and the software hase-ems-tour gps stock. Or there might also be some problem with the BCV.
Max boost was shaking between 1. Ferrita 2. Trionic 5 can handle easily also a base boost of 0. The adaptation takes care of that.
MY Saab 2. I am driving a stage 1 tune, made by the trionic suite. Whe i set up the base boost to exactly 0,4 bar, everything is fine, the max boost is perfactly stable. When i increase the baseboost only to 0. Its alway a little bit higher than the boost request, and falls after that short peak.
Not a lot, but a little bit. What do i have to do, to use 0,5 bar Baseboost on my bins?
