While the feat itself is impressive. What gets me is the lab, where do I have to work to get toys like that?

Yeah sounds like a good idea. This is a small todo list of things that I'll be doing. Open to suggestions. MIL - Remove the debugging debugging errors on init. And replace with something like milbench. For the short term this is going to have to go on the ignition_central.cpp file since that's where...

I have not made my mind really, but I am kind of tempted to suggest FSIO for TEN implementation. I suggest timingMultiplier and timindAdditive, which would be multiplier=1 and additive=0 by default, while TEN would make them multiplier=0 and additive=10, and suddenly you 10 degrees timing. Actually...

Ok, just added the VSS line, used a 1k pullup. According to speedinfo its counting events on the bench, so that works. TEN and the MAP lines will have to wait until next week.... 1k to 10k should be good. I seem to recall there are internal 10k's that can be activated, so you might not need to add a...

No dependencies, tiny independent java project. ^ That statement made me giggle a bit. Seriously though, the readme didn't document how to build it and a after a quick look it seems to have needed an IDE to build. Anyway, that pin is already there - it's called LED_CHECK_ENGINE ^ Indeed it is is si...

Some progress and questions. 1) MIL light is tested to work by grounding the ecu side, so I've wired it up to a low-side driver. Questions: - Is there a way to activate a low side pin from the dev console without having to write any control logic? Just want to test that the hardware can do it. - I s...

Ok, update on hardware modifications. Nothing is connected but I have more information on how things work. - MAP sensor, wire is connected to the ADC channel to be used. Sensor should be getting here tomorrow will validate with board before installing on car. There is one more free hole in the ecu c...

I for one think it's a step in the right direction.

I've merged a tiny part of the change - the trivial part. The rest would become the most significant source code contribution in a while which raises the question http://rusefi.com/forum/viewtopic.php?f=13&t=325 so I will call you. Ok, cool. I'm not working today so feel free to call anytime. T...

Ok. I'm giving up on MAF, joining the SD bandwagon. After seeing russian's neon run and what is required to calculate engine load with MAF. Ah fuck it... I'll give in to the simple pleasures of SD, intake's coming off anyways. So.. this means modifying the board and while I'm at it I might as well a...

Ok, update and as promised.. video. [video]http://youtu.be/ckS3BddpJt0[/video] What it can do: - Adjusts to normal loads such as using the brakes and turning on the lights. - Does not crash when coming off the throttle (mostly... see special case below). - Uses the builtin PID code. Problems/Todo: -...

Not sure what you mean here. The question of when to start the injection is an open question, where is a parameter which specifies that - you can control at what angle to inject fuel, but I have no idea when we want to inject fuel I meant deciding when the injector starts it's squirt. As to when th...

Hi, small update. With a question! I've been working on other things, but today i got a wild hair up my ass to validate ignition timing (another thing i should of done from the start). So I plug in the board and my timing light, set the whole map to 10.0 degrees advance (my car has 2 adjusted in the...

Ok, small update. I've basically re-implemented idle to use the PID algorithm and a state machine to judge when it should be used. It builds and mostly works. Changes up till now: - On the idle thread use the efitimems_t type for timestamps. Gives us milliseconds resolution. Right now I'm sampling a...

I'm stealing that one. Happens all the time at work.

This patch breaks stuff, it breaks stuff because this area is fragile and lame. See https://sourceforge.net/p/rusefi/tickets/125/ I see... messy. I the future it would be cool if engine_configuration.h and rusefi.ini were generated from a common definition file. Or some other more clever way of uni...

Ok, baby steps.

I think idleSolenoidPwm should be in engine configuration. Given that every user will want to change it to whatever they need from car to car within the same model. Here is a diff moving it to engineConfiguration.

hope, by May we'll have idle valve control for a stepper motor ;-) The only difference I can see between solenoid and actuator is the reaction time. A well designed algorithm may work for both without issues. As for ICVHomeValue, how is it different from idleSolenoidPwm from board_configuration_s? ...

Small update, I've been playing around with tuning the idle and a/c algorithms.

Here's an update:

Thanks, going to give this links a good read. As for the TPS lockout, this is a first hack to stop the problem. It will evolve into something smarter like using the highest seen value or something like that. Here's the patch for my fix, dead simple. diff --git a/firmware/controllers/algo/idle_contro...

Hi everybody, I've been playing with the automatic idle algorithm. I have propose two enhancements. TPS lockout - The algorithm thinks you are in idle when you are using the throttle. This is not good since it will close the ICV to try and get you back into idle RPM, when you let go of the throttle ...

Wow, congrats! This is a great milestone.

1 hp over stock! What is up with that dip between 3k rpm and 3.75k rpm?

Wow, it helps!



Now come the warmup enrichments.

Edit: I should note, this was after reflashing the new firmware and resetting to my engine type and adjusting the solenoid frequency. No more changes where necessary.

Alright, tasty data time.... With the attatched script and log I produced: Trigger StdDeviation ---------------------------------------- 0.000000 0.000000 52.960405 0.136736 122.635956 0.284776 216.897031 0.490407 232.640068 0.522702 288.819688 0.663799 302.646323 0.700889 412.448056 0.969577 482.81...

Found the issue with the round floats.

In rpm_calculator.cpp change the return line of getCrankshaftAngleN to

I could do a longer run and write small script to extract the info.

My timing is advanced my 2 degrees right now. Would that throw readings off?

Couple of missed starts and finally ran it for a few seconds.

These are set:
enable trigger_details
set_analog_chart_mode 1

Ok, got cranking working, it's rough but mostly reliable. Here are the changes I've done. - set_idle_pwm 800 - This got rid having to give it throttle while starting. I confirmed that with set_idle_enabled 1, the 600 cranking value it also works. - I changed the cranking parameters to the following:...

Ok, here is the data, along with it running.

Ok, I'm going to get data of it starting _AND_ running tomorrow night. Time was at a premium this weekend...
