Topic: Line graph not working properly
I have found the Single Reading and Board Control views for Air/Fuel Ratio are not very useful for three reasons: (1) the refresh rate - even when slowed to the max degree - is too fast to be readable, (2) the presence of three decimal places compounds this problem and (3) the reading is actually a Lambda reading based around a stoichiometric figure of 1 as opposed to 14.7:1 which I am used to.
I thought the line graph might be a better representation since you are not really looking for actual figures as an indication of fuel mapping problems but variations from what it should be. It should get richer as you accelerate hard, and leaner on deceleration. A line graph will provide the first indication that something is wrong.
I changed the setting on that Preset, but no matter how I manipulated it, the display would only show the line on the extreme right of the screen, ie the line commenced in the last 1/10th of the screen. Then there was a long wait until the line started again in the same place. It's as though the line was working its way across from the left of the screen, but was invisible until it got to almost the end when it suddenly sprang into view, then disappeared again almost immediately.
Before you ask, my DIS screen is in perfect condition - no missing pixels at all.
