From an educational standpoint, I'd like to ask someone to please explain the changes we've made in the LAMFA axis for pedal percentage. Does this bring LAMFA map in sooner than normal (starting at 50% now) in order to control the fuel delivery with LAMFA instead of another map? I know someone is going to say "go read FR" but lets put it into laymans terms for the sake of this thread.
Driver's Requested Relative torque (mrfa_w) closely resembles accelerator pedal position. You can "go read the FR",
sorry had to, to understand the relationship. I'm pretty sure that mrfa is the lamfa % axis.
You should post a screenshot of your LAMFA table now that you've mentioned you started at 50%. If you are enriching the mixture at 50% and your lowest axis value is 50%, that means that from 0% to 50% it will interpolate 1 to .85 or whatever your value is at 50%.
Example - 25% mrfa would (could) give you .925 lambda. You don't want to be doing that.
For LAMFA, I will typically modify the axis as 50, 60, 70, 80, 90, 100
I will put what I want my request to be at WOT in the 90 and 100 columns. I will then take those values and paste them into the 80, 70 and 60 columns and multiply the values by 1.05, 1.10, 1.20 respectively. This gives a smooth transition to my desired WOT fueling request, should the driver request less than 90%. It won't start enriching until after 50% because my 50% row is all ones, and my 60% is not much less than one.
Tunerpro's visual graph is really nice too. I'll use it once I get my main points figured out to make smooth transitions between those points.
