So really this does need a second MC with a PID to control rps as the load changes. Got it

yup you need to figure out the minimum throttle to idle the engine and put that has min value on the lever

I don't understand how this controls an engine's RPS or idles the engine at all. Do you need to manually adjust the throttle to maintain an idle?

to a pressure sensor connected to the pipe air manifold with a T pipe to a filter

where do I connect the manifold pressure node?

nevermind

how do you hook it up?

100% working for gas update maybe add it in the name for future people

well if they keep this change the fix i did wont mater its limited to 60 now
will update this comment or remove my own v1.9.10

i was wonder i was allow to modify of your microcontroller and repost i add a link of your creation?

i wish a pressure sensor to air/fuel volume convertion so i could get rid of the sensor and still supercharge

Amazing ECU. Can i use it on my truck i will upload the truck

Thank mistzy, i skipped to provide instructions for this microcontroller because in my intention this was only a demonstration for my guide (link in the microcontroller page).

Only a note on point 10a:
I often use a blow-off valve with a very similar function to control it to have a smooth operation for the engine but, in my experience, this is not an universal rule. In fact the function block (and even the presence of the blow-off valve) must be finely tuned depending on your engine (size, n° of clinders, rps...) and on the supercharger used (here you can try many different configurations...)

But, very nice guide guide to link the microcontroller!

right, for those who are coming here and want a quickstart guide:
ALL ENGINES
1. place ECU- REQUIRED
2. link the composite input to one of your engine's cylinders- REQUIRED
3. link "on/off" to the engine's power button- REQUIRED
4. link "starter" to any starters your engine has- OPTIONAL
5. link "rps" to the engine's crankshaft or flywheel- REQUIRED
6. link "throttle" to whatever you'd like to control the throttle- REQUIRED
7. link "air throttle" to the air manifolds of your engine- REQUIRED
8. link "fuel throttle" to the fuel manifolds of your engine- REQUIRED
9 . link "Stoich" to a lever or keypad to control the stoichiometric of your engine- REQUIRED**

FOR SUPERCHARGED / TURBOCHARGED ENGINES
10a. link your throttle input to a function block containing:
0.4+((1-x)*0.6)
10b. link the output of the function block to a variable valve and port that is split off from the pipe to the air manifold- PREFERRED**
11a. add a pressure sensor immediately before the air manifold (but after the super/turbocharger)- REQUIRED
11b. link the pressure sensor to "manifold pressure" on the ECU- REQUIRED

**improves the smooth operation of the engine by stabilising the pressure in the manifold

to the post owner: i'm so sorry for the comment spam, steam doesn't have an edit function

Yes, mathematically speaking this is true but pressure readings from the sensor should be limited at 90. I noticed that a couple of days after doing this ecu example and i've updated with this information only my guide, not this microcontroller.

just saying but max pressure should be 106-107 when supercharging
looking at the maximum fuel the manifold can output at value of 1 i am reverse enginery this ecu to add pid controlled rps hold lul
