^^^^^ john.....where the hell is the mighty ich when we need him? :D
Another member pm'd me a question about the ecm and the closed loop operation. This is my my understanding.
The ecm has a set of data tables correlating, RPM, TPS %, Ambient temp, coolant/engine temp and sets the parameters for fuel ratio and ignition outputs. We will call this Open Loop Operation. This is the ecm having hardcoded (EEPROM ?) parameters (values) for running the engine when it's a cold start (Ambient vs Coolant/Engine temp) Wide Open Throttle (TPS Throttle Position Sensor %).
Once the bike has reached full operating temperature, a subroutine (program) becomes active that initiates data tables and mathematical expressions that modifies the preset (open loop operation) outputs to the ignition, fuel injectors and also subsystems such as cooling fans, etc., etc.
There are other subroutines running simultaneously in the background such as the controls and monitoring for errors non engine related (kickstand switch, battery load, dash display communications, etc., etc.
In normal traffic riding (again boring) this makes the fuel efficient, ecology friendly, riding mode that the normal motorcycle hobbiest will spend most of his time.
I am more interested in performance riding styles that use the engine at its optimum capability ( :D), which means I am more interested in the open loop data tables and mathematical expressions for performance tuning (= acceleration rates :D )

Yes you are wrong" but to put my answer to your question in context, I didn't read the thread just wanted to make someone smile "!
:D john's posting way over my head so yes...i'll agree....he's all wrong. waiting for the beloved ich to respond.Yes you are wrong"
If you are married you are always wrong and happy or right and miserable.
If you are single well see above.
:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D
Open loop is one way commands, ecm>engine
Closed loop is two way commands, ecm>engine & engine>ecm which is self adjusting.
Open loop, set it and that's it.
Closed loop adjusts itself according ti sensory feedback fir "optimum" performance.
But yes. Lol
that's what she saidIf you are married you are always wrong
Man I am not sure if I started something here or if it was a coincidence? That being said I love being a smart a$$ for comedic value!
I saw the title and answered in my head "yes, you are" then i read the thread. Now waiting for ich
