What Is Data Logging On Cobb Accessport?

Data Log: a recording of engine sensor data, normally used to diagnose, tune or trouble shoot an EFI engine.

How do I view Accessport data logs?

Retrieving datalogs
To retrieve a datalog from the Accessport, follow these steps: Select “Datalogs” or “All files” from the Filter dropdown list. Drag the appropriate datalog file to your computer, or select the datalog and click the “Save selected file(s) to my computer” button.

What does af learning mean?

A/F Learning 1
Positive numbers indicate that fuel is being added. Negative numbers indicate that fuel is being removed. The closer to zero the better, but generally, the acceptable range would be +/- 10%.

What is data logging on tuner?

Data logging is the ability to view all major parameters that relate to engine operation. Some of these parameters are engine rpm, coolant/air temperature, engine load (psi), air/fuel, injector duty cycle, throttle position, vehicle speed, etc.

How do I open Cobb data logs?

Steps to Use:
From the main gauge display, you can simply hit the center button on the Accessport in order to start logging. If you haven’t pre-selected anything there are default parameters that will be logged which are typically the ones COBB Customer Support will ask you for.

What should my fine knock learn be?

Fine Knock Learned
–1.4 under full throttle. It is normal to see some knock corrections under full throttle, if it is constantly happening, higher than -1.4, and for long periods it might be a good idea to look into it.

What should air/fuel correction be?

An air fuel ratio of 14.7:1 is ideal for most gasoline engines when operating in normal closed loop conditions.

What does req torque mean?

Requested Torque
Requested Torque (Req Torque) -> Requested torque as determined by the ‘Requested Torque’ table(s) and used as an input to the ‘Target Throttle Angle…’ table(s) to determine the target throttle angle.

Can you get Accesstuner for free?

Cobb has removed Accesstuner Race, the free version of their tuning software previously accessible to all AccessPort owners, and has announced that the new version will be locked behind a paywall – a basic online training course offered by a third party – which will cost approximately $130US.

What is data logging used for?

Data loggers can monitor temperature, humidity, carbon dioxide, pH, pressure, voltage, current, and pulse – making them useful for a number of applications, including to: Verify temperature and humidity levels of storage and transportation facilities.

What is the purpose of logging data?

Data logging is the process of collecting and storing data over a period of time in order to analyze specific trends or record the data-based events/actions of a system, network or IT environment.

What is the benefit of logging data?

Data loggers are a reliable, low-cost and time-efficient monitoring solution for any measuring opportunity. Some of the key advantages of data logging include high accuracy, ease of use and greater versatility in every application.

What is Accessport manager?

Accessport Manager is software for your computer that allows you to transfer calibrations and datalogs between your computer and your Accessport. It also maintains the firmware upgrade process for your Accessport.

How do you data log with Bama SCT X4?

1. Select “I want to import a datalog from a device”.
2. Connect your BAMA X4 to an open usb port on your computer, then click Next.
3. Next, LiveLink will need to check the communication with the device, hit the check communication button, this may take a minute.
4. Once the information is confirmed click Import File.

How do you log data on a Duramax?

Turn the vehicle ignition On. Navigate to the Scan Tool -> F1 Select PIDs menu option. Navigate to the F1 Scan Tool -> F2 Data Logging menu option. Select F1: Record Data to commence the logging session.

How much feedback knock is too much?

In general, we consider Feedback Knock Correction ~-2.5 degrees or less to be “normal” and not of major concern. If DAM is below the ideal value and there are corrections beyond -2.5, this is good reason for further inspection.

Is knock the same as ping?

In spark ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode

What is false knock?

A knock sensor is precisely tuned to an engine’s harmonics and senses variations which it recognizes as detonation/ knock. This information is relayed to the ECU which then pulls ignition timing to protect the engine. In cases of false knock, ignition timing is being pulled for no reason, hampering performance.

What air-fuel ratio is too rich?

For maximum reliability at full power, air fuel ratios from 10.5-12.5:1 are considered best, depending on the engine. Richer than around 10.5:1, you start to get noticeable black smoke from the exhaust and the car can struggle to run properly without misfiring.

What happens when air-fuel ratio is too rich?

Too much fuel in the air/fuel mixture can make your vehicle surge, sputter, or even stall. For example, if the carburetor is set way too rich, it will push enough gas through to the combustion chamber and flood the engine. Your engine power might lag if the engine is being flooded while you’re driving, as well.

What air-fuel ratio is most efficient?

It used to be that 12.5:1 was considered the best power ratio, but with improved combustion chambers and hotter ignition systems, the ideal now is around 12.8:1 to 13.2:1. This is roughly 13 parts of air to one part fuel.
