Why no Load Site 100?
Why no Load Site 100?
I logged the car on several autocross laps yesterday and I never saw the maps use load site 100 at any time. I must be over simplifying how it chooses load sites.
Here is a graph of a 1st and 2rd gear pull for reference. Notice the flat shifting.
I know this doesn't show the MAF reading. It's too difficult to chart that since the numbers are so high.
Here is the same section in text.
What is the logged "Load Site" from? Since there are load sited for either boost, timing or fuel, which one is it referring to. I know that timing and fuel are using MAF Load numbers and my special constants show that 1700hz is 100% load. I am logging over 1700hz and my TPS is 100%. It seems like it that would justify the "Load Site 100". Am I missing something here?

Set your scaling for your graph to x/100 to get the MAF reading scaled into something you can see on the same graph..
Other than that.. I have no idea, I never noticed it on mine.. :\ From what I know, as long as its referenced by TPS and MAF, your load site should hit 100 periodically.. do you find the values your hitting (for timing boost and fuel) to be within that load site? Whats LCM? I never noticed that before? (Launch Control?) Its possible your hitting fuel cut or something before it can get to that.. you can reduce the MAF setting (for 100%) so your maf reading is 100% at 1650 or something in that range. Ya know.. It may be odd but double check it to be sure.. seems more like it may be up at 1800??

MAF frequency = load site.
There is some averaging that takes place in the MLP calculation, but the short of it is that your unmodified MAF frequency isn't quite high enough to hit 100% load just yet.
