Big day!

The excitement was short lived though once I calmed down and had a look at the logs.....lots of stuff need attention everywhere ...including the lying O2 sensors.

Tonight it was a little Smokey but it's finally starting to sound right

Running! ......and it only took me 9 frikin years

Tonight or was running without any backfiring or any other drama with 1.0ish lambda on both banks idle redline. Time to drink.

I meant from the point of integration testing it would be a nice way of developing ecu if rusefi running on actual firmware could be ran against good software emulating sensors based on injection and ignition.

That would allow us to estimate effects of jitter to afr, ect and cylinder pressure?

So.. we could connect brain board to this using the usb drivers provided if we can emulate the AEM/EL protocol and then develop the ECU without having it bolted on engine all the time you want to test stuff?

You don't need to connect anything, this runs on a Windows pc. You can only run EL models but you can still test any control logic you're interested in. I could probably make the engine simulation better and more complete but it's pretty good I think.

Of course that would be as good as the engine simulation but would allow testing quite a lot of stuff out.

First of all - I'm sorry for the incident. On the other hand, let's look at it this way - you cannot make important stuff without making important mistakes from time to time.

Now, thanks a lot for this thread! I am a computer engineer currently interested in car mechanics and car tuning, and this engine simulation environment has made my day. I will keep tinkering with it for a while.

The mess is pretty much all cleaned up at this point....and finalizing the plans for a detached garage/shop.

Glad its useful.

I made a few little changes to the engine control code, the attached version seems to run the engine correctly. I'm still working on a lot of other things so I can't say everything works the way I planned yet but it seems to be pretty close.

If you figure out how to make the simulator better please share

Yes......I had a pinched injector wire that i found and fixed, but the injectors are 1000cc/min and one was spraying fuel any time the key was on. Best i can tell it filled the muffler and when the engine started it spray about 1/2 - 1gallon of gas out in a 4x15 foot flaming mess. No injuries but the shop is in the basement of our house....28k in cleanup costs before repairs and ruined stuff is replaced which probably another 10k. The estmate for the car is 6k. The engine itself was not hurt.....thank goodness for insurance.

It's all fun and games until someone sets their house on fire.....

The car got banished to the garage today....and got it's first bath in 10 years on the way. then I'm losing most of the basement and the shop will need to be walled off with double drywall and it's own hvac. Lots to do

before i set the shop on fire

hold on, you serious? are you fine? is your garage fine? is the engine fine?

PS: is this picture upside down?

It did run the engine the other day for a couple minutes...before i set the shop on fire.

Note to self....don't start cars for the first time inside.........

dear god, can't imagine the complexities associated with that.
Not like designing an adapter plate or something, has to work on a human.

unless you meant medical devices as in "marital aids". then that is another story.

It's a lot of statistics or at least it was when I was doing stuff for fixing hearts, I moved to dental a few months ago which for the most part isn't going to kill anyone and in most about aesthetic and price.

Back on topic, the layout is fast. Literally right-click>select what you want to add (gauge, slider, etc.), select the channel it should be reading/writing, the drag it into place. You could build that whole layout from scratch in under an hour.

For me, (not being a programmer and prone to many, many typos) its really nice to be able to get the ECU to do what I want and try it on the PC not an engine. Testing on a PC also means I can "work on the car" at lunch time so its not so hard to find quite time away from the kids to do it.

LOL.....I design medical devices in my day job so you're good
That sounds pretty serious. So your an EE?
