    Default Sniper Datalog Scatter Plots - Custom Parameters?

    Playing around with simple Scatter Plots in the Sniper datalog screen. The Sniper Tuning Manual: says on page 45, "You can setup a calculation AFR*Fuel as a surrogate for airflow" and shows it as the Y-axis variable. It also shows a plot using "CL+Learn" as the displayed parameter of a MAP vs RPM table to evaluate the state of AFR adjustment by the ECU.

    I could not find any instructions anywhere on how to do this until I looked at an EFI V4 Datalog screen for comparison, there was a menu item called "Math Channels" not found in the Sniper Datalog menu screen. When I "pressed" that button, I thought "OK, there you are!" and created parameters that were added to the pick-list. But EFI V4 will not open Sniper datalog files so ...

    1. Am I still missing seeing the correct way to perform math operations on parameters in the Sniper datalog software?
    2. Is the Sniper Tuning manual just copied from the EFI 4 (and up) documentation and showing a feature that doesn't really exist for the Sniper?
    3. If so, can you convert Sniper datalogs to a format recognized by EFI 4 (and up)?

    The Sniper EFI & Terminator X EFI datalogger don't have Math Channels. The regular Terminator, HP & Dominator EFI do. Also, V4 & V5 EFI software is not for the Sniper EFI.
    May God's grace bless you in the Lord Jesus Christ.
