Load is used all over the user interface, but in some cases it is hardly clear which load each load refers to. On my install, there are three different loads controlling different aspects;
1. Ignition load is referenced to MAP
2. AFR load is referenced to TPS
3. fuel is controlled by MAF
So when the AFR/EGO dialog says "Active above/below load" which load does it reference? AFR table, ignition or fuel? Logically it should be either AFR or fuel, it wouldn't make sense to refer ignition load, but which one is it?
Likewise in the closed-loop PID activation criteria: Max decel load. It would make sense that it is fuel (in this case MAFload), but it's not specified.
I know I run an odd setup and that most people will only use one load parameter, but it would really help understanding if this was a bit more specific in places. If I was using primary/secondary loads as well it would be even more ambiguous.
Everything is in reference to the current state of the art, pre1.4b12.

Re: A loaded question...
Isn't Load simply MAP/Baro? And if a baro sensor isn't being used it's pretty much just MAP?

No. What load is depends on what sensors are installed and how you choose to use them.TheSilverBuick wrote:Isn't Load simply MAP/Baro? And if a baro sensor isn't being used it's pretty much just MAP?
BTW: A baro sensor is just a MAP that only measures ambient atmospheric pressure, it is not capable of providing any load information.

Re: A loaded question...
I agree that the load reference is a bit vague. However, it should be easy to determine what load is actually being used for each setting. For example, Idle Advance and Closed-loop idle will be using MAFload. AFR/EGO is a little difficult to determine, but it should be MAPload (I'd double check since they could be TPS in your case). And overrun fuel cut should also be MAPload.
I had similar confusion and eventually figured it out by testing a few threshold ranges to get an idea of what load was being used. Simply adding the info the the tooltip would be very helpful.
