Can any help clarify what load is in ecuflash? I finished watching merlin's video series but still have questions

 

Load can be thought of like how much "work" the engine is being forced to do. Think about how the brakes work, as you push harder on the pedal it squeezes the brake pads. As it squeezes harder, the force that is being exerted on the pads/caliber could be considered load (although it's known as friction). It's similar in an engine based on what the clutch/tranny is doing, the car is heavy and making it move requires the engine to work harder.

So let's say the egine is at 3000 rpm with 0 load, it can spin freely with almost no effort because there is no load to slow it down. As you release the clutch, the load increases because the engine is being required to turn the transmission/axles/wheels/etc.

If the engine is at 3000 rpm with 40 load, it takes more fuel/power to keep the engine at that rpm because there is a force trying to slow down the motor by putting resistance on it.

Hope this helps, I'm sure you could find some good youtube videos explaining these principles better than I can.

 

I think that is more than sufficient. I very much appreciate the speedy response and the analogy of the brakes and clutch example. Thank yiu

 

Load read by the ECU can be misleading also.
Using Speed Density for example...

Load is calculated based on MAP (manifold air pressure) reading and values in your VE tables. You could have two cars both logging 25 psi but one logging 300 load and the other 225 for example. It's really just a reference value when it comes to tuning. Both of these cars could run exactly the same despite logging different load

 

Info overload. I have a base Lancer so na. Tuning. speed density? I think this is an alternative to a maf system?

 

You really don't need to know about load to tune your car.

Just use it to relate your logged data to your maps in your tune so you see where to modify your fuel or timing map.

 

load is a variable that you log so that you can plot where on the fuel and timing map your ecu is reading, and based on other collected data, make adjustments.
