It’s not a gauge with a sweeping needle, just a ever changing number with a memory spot below it showing your highest boost.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Dear 996 enthusiasts Unfortunately I was in the situation that couldn't use my beloved 996 (996.2, 2002) for a long period of time, but times have changed and I am ready again. I would like to give you some information first. Engine was completely rebuild (IMS, oil service, filters,..) before I out the car into garage. The car has driven 120.000km (75.000 miles), automatic transmission. It was last started 2 years ago without any problem. Couple of weeks ago I wanted to start it again but it just cranks and doesn't want to start. I assume the fuel is very bad so my plan is to drain the fuel out of tank and start from here. Option 1. is to bypass the fuel pump relay, connect the hose to the fuel pump and pump the fuel out this way. I have heard that in this care some fuel remains in the tank so there is Option 2. to open the fuel filter cover and pump the fuel straight from the fuel tank. What do you think? My next step would be fresh fuel, start spray and give it a try. Should I be careful with some other things? I can hear the fuel pump when I turn the ignition, the RPM moves a little while it cranks so it shouldn't be a crank position sensor. Thank you for any suggestions and sorry for my broken English Have a great day! Best regards, Blaz

Doesnt seems anything below can read as boost gauge? MAP? Thanks And what monitors do you guys have set up on the gauges page? Useful Monitors In Every Situation: Ambient Pressure Barometric pressure reading, allows a tuner to see the atmospheric pressure where you drive your car and makes it easier to compensate for altitude. Boost Error The difference between the amount of boost requested by the computer, and what the vehicle actually has. Engine Oil Temperature Temperature of the engine oil helps with checking health of the engine, how hard it's being pushed, and whether the oil would need a cooler or to be changed. Engine RPM Engine speed in RPM (revolutions per minute) Provides a refereance of what the engine is doing so that all the other values make sense. Engine Temperature Temperature of the engine allows us to see if the vehicle is having problems related to overheating, or being pushed too hard. Ignition Angle (Actual) Final ignition timing value after all corrections. Injection Time Injector open time in milliseconds. Intake Air Temperature-Intake air temperature in the intake manifold. Knock Sums Cyl. 1 Knock Sums for cylinder number 1 Knock Sums Cyl. 2 Knock Sums for cylinder number 2 Knock Sums Cyl. 3 Knock Sums for cylinder number 3 Knock Sums Cyl. 4 Knock Sums for cylinder number 4 Knock Sums Cyl. 5 Knock Sums for cylinder number 5 Knock Sums Cyl. 6 Knock Sums for cylinder number 6 Lambda Bank 1 Air fuel reading from the wideband sensors Bank 1 Lambda Bank 2 Air fuel reading from the wideband sensors Bank 2 Long Term Fuel Trim Bank 1 Long term changes made to the fuel table for bank 1 of the engine. Long Term Fuel Trim Bank 2 Long term changes made to the fuel table for bank 2 of the engine. MAF 2 Mass air flow reading Bank 2 MAF Mass Airflow Reading Bank 1. Manifold Absolute Pressure Intake manifold pressure MAP This is also considered to be boost pressure. Pre Throttle Pressure Sensor Pressure in the intake system before the throttle body (997.1 only) Short Term Fuel Trim Bank 1 Short term changes made to the fuel table for bank 1 of the engine. Short Term Fuel Trim Bank 2 Short term changes made to the fuel table for bank 2 of the engine. Throttle Angle Angle of the Throttle Vehicle Speed Vehicle Speed List of Available Monitors: Actual Camshaft Angle Bank 1 Actual camshaft angle for Bank 1. Actual Camshaft Angle Bank 2 Actual camshaft angle for Bank 2. Actual Gear Current transmission position. Battery Voltage Battery Voltage Catalytic Converter Temperature (Modeled) Temperature of catalytic converter. This is a modeled temperature so not 100% accurate. Cold Start Enrichment Range 0 Cold Start Enrichment Range 1 Cold Start Enrichment Range 2 Coordinated Torque for Cylinder Filling. Current Starting Adaptation Factor Amount of correction in percentage of correction when starting the car. Distance Since Power Failure Distance amount since a power failure. Distance With Check Engine On Distance with a check engine light on. EGT Downstream of Cat (Modeled) Exhaust gas temperature behind the catalytic converter. This is a modeled temperature so not 100% accurate. EGT Upstream of Cat (Modeled) Exhaust gas temperature before the catalytic converter. This is a modeled temperature so not 100% accurate. Engine Compartment Temperature Engine compartment temperature. Measured in the back of the car. Engine Torque Loss Fuel Level. Maximum Torque Maximum torque value Minimum Torque Minimum Torque Value Nominal Throttle Plate Angle Actual Throttle Angle Operating Time Since Power Failure Amount of time since power failure. Radiator Fan Request Value Radiator fan on and off request. Relative Secondary Air Mass Bank 1 Relative Secondary Air Mass Bank 2 Set Point Torque Set point torque value. Turbo Duty Cycle Bank 1 (Target) WGDC/VTG target duty cycle from 0-100% Turbo Duty Cycle Bank 2 (Target) WGDC/VTG target duty cycle from 0-100% Turbo Duty Cycle Bank 1 (Actual) WGDC/VTG actual duty cycle from 0-100% Turbo Duty Cycle Bank 2 (Actual) WGDC/VTG actual duty cycle from 0-100% Target Camshaft Angle Bank 1 Target camshaft position for Bank 1. Target Camshaft Angle Bank 2 Target camshaft position for Bank 2. Target Firing Angle of Torque Intervention No Description. Target Idle Speed Idle speed target. Total Mass Air Flow (MAF+Tank Vent) This is a combination of MAF plus the tank vent recirc total airflow. Warm-up Cycle Counter Cycle counter for the warm up cycle.

POST 7Original post

It just mirrors the factory dash one. Better to get a real boost gauge. I monitor: batt voltage, oil temp, water temp, intake air temp, EGT, o2

POST 8Original post

The video I did isn’t uploading. Click the highlighted gauge and goto manifold absolute pressure. That’s your boost pressure

POST 9Original post

MAP This is also considered to be boost pressure.

This is a source reference. Confirm exact model applicability in the original material.
