How to Data log 11+ (older cars below)

Use livelink generation 2 from the sctflash.Com and log the items below.

Important notes-


Do not use “sae” or "Epid". Only use "Pid" or "Dmr". Do not use multiple versions of each item. If you have questions about which to use, please call us at (321) 206-9369.

To get started data logging open the live link program and click “I want to data log a vehicle” and follow the prompts (validate all parameters). To start datalogging turn the key on, with laptop and tuner connected, hit the green button in live link (upper left hand corner), start the car without turning the key back off, and let it log for 30-60 seconds at idle(longer if the engine is cold). Once you see the short term fuel trims change from a static 1.0, you're now in "Closed loop" so we need at least 30 seconds from that point on. Once you have recorded that 30-60 seconds, slowly rev to 5000rpm over a period of 30 seconds in neutral, very slow, not quick blips. Stop datalogging (red button) and save this file (file menu > save datalog as...See “important notes” above for how to name your file!!!)


On a second logging session, run the vehicle at wot through 3rd or 4th not both this can be done by selecting the gear using the shifter in an automatic transmission car(15+ car must be in sport mode to hold a gear and will only hold a gear if you command that gear using the paddle shifter). Make sure you see the short term fuel trims moving before you do the pull. Don’t exceed the speed limit or break any laws while doing this, if the car has too much power for the street it should be logged on a dyno. It is critical for the car to not get tire spin during the log and that you advise us that you did get tire spin during the log, if you did(we prefer logs without tire spin). Do this from a very low rpm, about 1000, up to the vehicles rev limiter. Only send one or two short logs. If you have a wideband wired into the tuner don't forget to correctly configure the analog inputs. If you run the car on a dyno make the pull in 4th gear(11-16 mt82 cars need dyno’d in 5th) starting at 1000rpm. Do not send more than two logs or repeats of the same thing. If the vehicle is boosted make sure the a/f does not go above 12.5-13.0 for more than a second while at wot. Please note whether traction control was on or off during the wide open throttle pulls. Save the datalogs under the file menu of live link and reply to this email with them, this is important so we have all of your car and order information. 

Choose the following items:

  • Air control temp 2 F (or "downstream")(supercharged only)
  • Battery voltage
  • Coolant temp deg F
  • Etc actual throttle angle
  • Etc desired throttle angle
  • Fuel pump duty cycle ( Shelby only)
  • Intake air temp F
  • Knock sensor
  • Lambse bank 1 and 2
  • Load (as a fraction)
  • Long term fuel trim bank 1 and 2
  • MAF frequency
  • MAF lb. per min.
  • Measured AFR bank 1 and 2
  • Output shaft speed
  • RPM
  • Short term fuel trim bank 1 and 2
  • Spark Advance
  • Torque source
  • Vehicle speed
  • Wheel torque error(Not always available)

On 5.0L mustangs:

  • Variable valve timing intake cam angle bank 1
  • Variable valve timing exhaust cam angle bank 1

Auto trans:

  • Commanded gear or gear ratio

How to Data log 1996-2010

The best bet on 1996-2010 cars is to use livelink generation 2 from the sctflash.Com (v2.5.2 is the latest as of jan. 2016) and log the items below. 1996-2010 data logging

Computer Code Location

The "Computer Code" or "Catch Code" identifys the program that is in your vehicle's computer. When we custom program an SCT Tuner for your vehicle the code is usually required. This code is 4 letters and numbers long, an example would be "ABC1". There are no dashes before or after the computer code, it is not a part number or calibration code.


If you can not find the code go ahead and place the order, we will contact you if we need additional information. We often know the codes for common vehicles such as 03-04 Cobras and GT500s.


On 2004 and older vehicles the code can be found on a small white sticker on the passenger side door jamb or door. If this sticker is worn off you will need to look on the computer itself. On Mustangs the computer can be found behind the passenger side kick panel. On trucks the computer can be found going through the firewall on the passenger side, often the code is visible from underneath the dash. On large cars the computer can be found under the drivers side dash.


On 2005 and newer vehicles the code can be found on a small white sticker placed on the computer itself. On cars the computer is often on the passenger side front of the engine bay, on gas trucks it is on the firewall.


11-13+ have the computer in the same place as previous years, but the sticker will always be by the connectors.


The code is not part of a long part number, it will be by itself, usually in large letters. An example code is ABC1.


It is possible to find the computer code by plugging a flash tuner into the OBD2 port. When you read the code out through the OBD2 port it is called the strategy, using this method the code is 7 letters and numbers long. It can be even longer on some vehicles and include a part number, we can use that part number if there is no strategy code present.
