-ve found after ADD Trim number ??
« on: June 14, 2016, 06:27:59 AM »
Hi to All,
As a relatively new user of the GS911, I am seeing Add Trim 1 and 2 numbers of 4.0 and 4.2 and Multi Trim   1 and 2 numbers 1.2 and 1.02.
Are all these numbers percentages ???

What was interesting was that all the numbers ( from the data download and graphed ) were positive. I did a second scan and watched the PID`s on the laptop but found that the ADD trims still showed 4.0 and 4.2 BUT there was a ( -ve ) negative indication after the numbers. I can not recall if the -ve was in a bracket but sure it was on the ADD Trim and not the Multi Trim.
The Data and Graph still showed a positive 4.0 and 4.2

This -ve has me tricked.

The bike is a BMW R1200R 2010, fitted with an AF-xied, appears to run quite well other indicators appear to be within spec. All indications are that I have a vacuum leak.

Thank you for your assistance.
