work in progress Hai from The Netherlands #19
Re: Hai from The Netherlands
I typed a quite long reply with files attached (drive link) but I forgot to hit submit Stupid me, glad its been fixed. I'm working on getting the trigger today, got my scope out and power supply on the car, gonna be a good day
Re: Hai from The Netherlands
FUCK YEAH!! Say hello to the first Dutch car running RusEFI!
Will upload vid in a moment (slow connection) and write a summary. I haven't even uploaded a damn basemap, configured IAT enrichment, warmup, coolant enrichment. No clue how see could even run, and have good power (runs bad, good power)

Re: Hai from The Netherlands
Got the vid, raw upload (not public, only for people with link):
[video][/video]
Config:
No basemap (fuel and timing), just whatever tunerstudio was running default (no leaning out during running)
Idle air not working yet, kept it running manually
No enrichments whatsoever
I did change a couple of things today, and found a problem/bug.
-removed the MAX9926, made some changes to the opamp circuit to accept hall (changed some resistor values and removed some)
-testing the things manually isn't working, every IO test does nothing in tuner studio or in the console, just no response (hardware, message window does say benchtest)
I'm soldering up the MAP at the moment, AFM's suck. Also gotta get my wideband on it again, but need the car to be reliable up until next friday so that's not happening until then (stock ECU doesn't like the fake narrow band output)

Re: Hai from The Netherlands #19
Welcome rusEfi #19
Did you solder the LEDs on the high and low side outputs - do they blink when you hit bench test? Will try it on mine today just to confirm.Thommm wrote:-testing the things manually isn't working, every IO test does nothing in tuner studio or in the console, just no response (hardware, message window does say benchtest)

Re: Hai from The Netherlands #19
very nice, very nice.
Welcome to the friendlier side of internet crazy
Re: Hai from The Netherlands #19
Everything is working, still fighting with IO test but working sometimes. I'm already running MAP by the way with speed density. Already drove around 10 miles on SD but I still need to buy tuner studio pro to get auto tune, doing it by yourself is kinda dangerous

Re: Hai from The Netherlands #19
Please be careful with too much driving - timing is also important so please double-check what's there.
Can you post your configuration by the way? I want to use the i-o settings for my own 1.6 configuration. You are also in charge of the base 1.6 tune now
What communication wire are you using for which bench test software with issues? TS via VCP? rusEfi via miniUSB TTL?

Re: Hai from The Netherlands #19
Hi, and congratulations!
I am getting closer on my 1990 1.6L Miata.
I would really like to see what settings you are using for trigger and ignition.

Re: Hai from The Netherlands #19
I've got a quite decent ignition basemap (stole it from some megasquirt Miata ). It's very conservative, and while revving stationary no knock was heard. I'm at my girlfriend now, but I'll try to post a good write up tomorrow evening with pictures and a diagram (which pins used for what, opamp circuit, jumper Wxx board to Wxx cable and such) and my config Idle isn't working yet by the way, busy week ahead but I'm going to reverse engineer the stock one, see if there is some kind of filtering going on (very likely :p).
But I'm slightly confused, we already had like 2 Miata's running right?
Coming week I'll get to installing the wideband and the knock sensor, then the fun stuff begins When smurf's dialed in up to my liking I'll post the map with most timing/fuel and a more conservative tune. Has anybody tried the knock sensor filter yet by the way or am I the first?

Re: Hai from The Netherlands #19
While you are the fifth miata, between some of them being 1.8, some of them using the older board, none of them actually putting much road miles and me not making the effort, the knowledge is lost. A BP engine with most miles is actually the FWD yellow race car - but again, that's a deeply modified 1.8

Re: Hai from The Netherlands #19
Haha, well, I'm doing about 8000 km's (5500+- mi) a year. And it's not looking like I'm swapping back to the stock ECU. I also just bought the full tuner studio
Re: Hai from The Netherlands #19
Mooi gedaan
Number 19 up and running and sounds good. It's motivating to see some of these projects get to this stage. Most boards unfortunately end up in a box somewhere in the garage.

Re: Hai from The Netherlands #19
Wow, that's pathetic, why would you buy it and then not use it? I've also bought just a PCB which I figured I wasn't going to use, but by the end of this summer it's going to be running an E21 BMW
I do have a small bug or problem from my side. If I start the ECU without the laptop connected it does not do anything. It does not seem to remeber settings. I can see my ignition leds turn on so it does not even apply the config. Only when I attach my laptop and its enumerated, it works. Tunerstudio does not even have to run for it to start working. I'll make a vid in a couple of hours and post the link here. Quite annoying if you MUST use you laptop to start the car xD

Re: Hai from The Netherlands #19
Wauw, such a coincidence! I just read that thread this morning, didn't see it impacted the ECU that bad :p, more flashy LED's are better right?
I've made a new vid of the problem, but that's not very important anymore :/
[video][/video]
Although I do succesfully start the car cold for the first time (not very smooth, I have to admit). Tried some times before, but was never successful, need to edit cranking temp correction I think. And install wideband. And replace crappy water temp sensor. And install new IAT. And finish downpipe and make woosh-woosh nooise!

Re: Hai from The Netherlands #19
Ha! Didn't fix it . You may wonder why I'm so happy, well, I did manage to fix it It's been a while since I had a bug that really challenged me :p. It turned out that the second processor on the mini usb side can pull the STM32F407 into reset, which it does, right until after enumeration. The solution was to remove a soldered jumper and a resistor. SB11 and R68 to be precise. I must admit that I sadly found something like this one the STM forum, so I can't claim I invented it
On a more serious note, the audio circuit has influence on the injector pulse width right? To work around this, did you guys just remove those chips or is it the R/C/L networks that are causing the problem?
FOR MIATA PEOPLE WANTING SPEED DENSITY WITH MAP:
In the AFM there is a contact for the fuel pump which shuts of the fuel supply if it does not measure air. So when you throw the AFM out of the window, your car will not start! Trust me! The easy solution is to jumper the two contacts at the end of the AFM plug wire, I think you can also jumper a contact in the OBD I box near the AFM (not sure). The nice way would be to rewire it (which nobody will do). Almost ready for boost! Wideband will be installed next week, when the basemap is done I'll post it and the config on the forum (still editing stuff, especially cranking and temp correction).

Please elaborate - which GPIO channels are we talking about here?Thommm wrote:On a more serious note, the audio circuit has influence on the injector pulse width right? To work around this, did you guys just remove those chips or is it the R/C/L networks that are causing the problem?
No, we have not removed anything from discovery so far but it does not mean we should not.

Re: Hai from The Netherlands #19
Oh, umh, sooorrryyy. I kinda forgot I really should pay more attention to my todo list. Since smurfs starts and runs OK (good enough I think for a basemap?) I'll include everything in the writeup. I'll start a topic in my car and me about it
Thanks Chase! If you ever need assistance, just mention it

Re: Hai from The Netherlands #19
I'm sorry Andrey, altough I'm good with hardware, which is surprisingly well covered here, I completely suck at software. I can debug stuff up to a certain point and I do understand C/C++, but I'm not great at writing code. This coming holiday I will however start (if it hasn't been done by then) at the thing Garred(?) pointed out to me in hardware realm.
