Megalogviewer HD Tables

Post by lagos »

I love being able to view the delta of actual AFR and AFR target in table form, however is there an easy way to correct specific cells so that they match their target?

Right now, I am manually calculating a percentage difference between the actual afr and target, and then multiplying my VE table by this percentage. Is there a way to add a single button that does this? Something like Match Cell To Target would be really handy.

That is what VE Analyze does, only with some other factors to improve accuracy.

I understand, but it would be useful to have a combination of the two features. You can run around in circles running the autotune over the whole map.
Using the table feature, I have found it helpful to pin point specific problem cell and only adjust those, but currently you have to write down the specific cells you want, switch to a new tab, setup a filter, run autotune, deselect what you don't want changed, etc..

It would be great to be able to pick a few cells from the table and click fix, all in that same window.

I can see where that would be useful, the trouble is, that it would be making a generic screen that is meant to plot any X, Y and Z, then putting in a function that is tightly coupled to a specific function.
That doesn't mean it can't be done properly, but I might need to let that stew a little to think of a proper way.

Perhaps one way of doing this is to have a variable called AFRdot and also AFRtarget1dot (and AFRtarget2dot). When the AFRtargetdot hits a big required change in AFR, due to a user intervention like TPSdot exceeding a threshold, a timer starts and the time delay to the upcoming expected big swing AFR is measured. This is the lambda delay for that particular MAP and rpm and hopefully VEanalyse can be asked to autotune the lambda delay table.

You could then datalog a new variable which would be the difference between the time lag adjusted AFR and its AFRtarget so long as you can decide what to do about the delay between reading data and writing to the datalog.

kind regards
Marek
