The first 3-4 revisions will be for MAF scaling. No wide open throttle. You will be collecting data at idle and then collecting data all the way up to cruising at 75mph....small throttle changes and all under 4000rpm.

The next couple revisions will be partial WOT pulls from 2000-5500rpm in 2nd gear to get the wgdc and boost set.

The rest of the revisions will be 3rd/4th gear pulls from 2000-redline.


IAT = intake air temp
FBKC = feedback knock correction
FLKC = fine learning knock correction
IAM = ignition advance multiplier
DAM = dynamics advance multiplier
MAF = mass air flow
MRP = manifold relative pressure (boost)
IGN = igntion total timing
IDC = injector duty cycle
WGDC = wastegate duty cycle


Romraider Datalog List for WOT

Parameters to Log – remember some of these may not be visible until hooked up to the vehicle

• Engine load (g/rev)
• Engine Speed (RPM )
• FeedBack Knock Correction (fbkc)
• Fine Learning Knock Correction (flkc)
• Ignition total timing
• Injector Duty Cycle (IDC)
• Intake Air Temperature (IAT)
• Manifold Relative Pressure (MRP) (4 byte)(or direct if 4byte not there)
• Mass Air Flow Voltage (MAFv)
• Primary Wastegate Duty Cycle (WGDC)
• TARGET Boost
• Throttle Position
• Wideband (LC-1/Uego)
• Requested Torque

AccessPort MAF Scale Logging

Load up the map and Datalog the following parameters for ~20 minutes.

A/F Correction #1 (%)
A/F Learning #1 (%)
Calculated Load
Closed Loop / Open Loop Switch
Engine RPM
Feedback Knock
Fine Learning Knock
Intake Temperature
Mass Airflow Sensor Voltage (V)
