Continued from dmaxpowered's thread. I have been messing around with this for days now, and have become all but convinced that the axes' are messed up in some way.

Hopefully, as soon as possible this can get some attention. My tuning constructs begin with a fuel pressure histogram, and get built from there. This makes for lots of guessing and headscratching.

Pressure is everything guys, I hope we can get to the bottom of this soon. I can't go on to dsp5 knowing I will only compound these issues 500%.

Not taking statistics in college i did a little quick search on histograms. How do you use a histogram to make a pressure map? I totally see basing you tunes around pressure, but i'm not getting the histogram part. If it is secret i understand.

Histogram is just a fancy word for the relationship tables. Each table is a histogram. I found some time ago, that much of the secret to refinement, began with new pressure relationships. It sets up the foundation for good pedal feedback or lousy. Crude pressure histograms, feel crude. I don't publicize my specific version (different for each generation) but that is the idea.

OT, the rpm axis is definately messed up. There is almost no question that the 200, 300 rpm columns are actually 600, 800

Yeah i would say so... they just look wrong.

it is also conspicuous that the ECT pressure correction tables are rpm scaled just like the LBZ main pressure table. 3 less columns also. My guess is these are correct, and the last 3 colums are discarded.


0 400 600 800 1000 1200 1400 1600 1800 2000 2200 2400 2600 2800 3000 3200 3400 3600 3800 4000

Yeah probably. Did you get my post about there being the ECT FP multiplier table missing?

bump, in the hopes of getting a response on axis scaling, or whatever else might be in error.
