TunerStudio and Microsquirt

I'll carry on answering my own questions, hopefully it will be of use to others.
As the easiest thing to try first was a change of "ignition input capture" I changed it from rising edge to falling edge. That sorted it, I had a single long bar for the missing tooth and the RPM sync tab was green.



Now I can get the #1 tooth angle BTDC checked and set. Set the timing to fixed at 10 BTDC and off we go. After some chasing around it was bang on with a setting of 110 degrees. Not what I expected, I had read somewhere that for this engine it was 80 degrees. I also remembered halfway through that the ECU has to be powered down for timing changes to take effect (even though it is burnt to memory) which was the cause of the chasing around.
Start up next! It will be a week or so though.
Edit. I think the reason my log looks so"up and down" is because I used a 3000ms log instead of the default so there are a lot more cycles in the same length of graph.

Yes I'm using the msextra manuals plus the old forum. It's pretty much dead now but there's lots of information in there.

thanks , ill message him and see.

the speeduino. i bought the ua4c one, it looked really good, but ive had endless problems with it. First it comes with connectors on the board, and the terminals, i found them really had to crimp, so after ages trying i bought some ends and soldered on. i don't like doing that but it worked. as its on a k series, a guy on the speeduino facebook page modded the code to read my flywheel pattern. it started up, and ran for maybe 15 seconds then cut out. i couldnt get it to restart, but i knew it worked as it had run. that took ages to reolise it should not have started and i needed a little add on board as i had a ve sensor.

there seems to be no good info about how to do things and people on the facebook pages seem to know everything but not help so much.

also what i didnt reolise is when i uploaded this code into the arduino, i had a preproduction version, so when i was making changes to like the ve table it just crashed. So i worked out how to fix that and then it still didnt work, and it was as i hadnt formatted the arduinos memory with the speedy loader app. Then i had the ecu inside connected to my normal pc, was calibrating temp sensor, put it back on the car and now no crank signal.

today is capethorne hall car show, if i had bought microsquirt my r100 would be there, but as of the speeduino problems, it isnt.

what version of speeduino do you have ? it would make sense to get another one, and microsquirt is really good but its quite dear for what it is i think.

the new release fo the speeduino software will have the mems in it so there will be no problem with the software.

this is the ecu i have

I didnt know the microsquirt was so much now, it was £250 i think when i bought the one for my bmw [has a volvo b230 in it!] When i lost the crank signal i thought it was a bad connection so i tried reflowing bits on the board, and i don't trust it now. I could buy another ua4c, either wait for the official updated software, OR i could fit a 32-1 trigger wheel, and then even if i take the gearbox off the car and go for a different set up, the ecu dosnt need to be changed and itll work with standard software.

I understand the diy bit but its just uve had so many problems with it ! Should have bought the prewired plugs, and should have left it in the car not unplugged it often to take it in teh house to change stuff.


what i do find strange is that there is no maps i can find anywhere to get you up and running. there are a 4-5 on the speedyloader app, i just thought id be able to download something and get it running.

After a long time doing other stuff and then going through some issues with wifey's Pop I find myself back here.
Today I finally put the last of the problems to bed and went for a start. Checked that the fuel pump ran, all good.
Ignition on, immobiliser off and dam me if it didn't start first turn of the key!!!!!!
However it didn't last long as it was eye wateringly rich and died after 20 seconds or so. Injector pulse width is off the scale and lambda gauge is below 10.

I'm now in uncharted water so any clues would be much appreciated. Is it as simple as reducing the VE table values?

Thanks kevins
I have reduced the cold start and run enrichment right down (to the point I doubt it would start if set up correctly).
I've finished for today, I may get a play tomorrow with luck.
Good points to take from it, oil pressure is ok, the alternator charges and the engine has no odd noises.

vitesseefi it does run a MAP sensor. I have yet to a) keep it running long enough to get a reading and b) work out where in TunerStudio I can observe said reading.
As I have said, this is a very steep learning curve for me.

Thanks vitesseefi
I have just sat playing with TunerStudio after breakfast (wifey away so I can!) and found a real time display page in general settings. After reading your reply above I then noticed the kPa gauge on the dashboard which I had somehow missed completely!
When connected and online the gauges all work. The TPS is calibrated. I had just thought of applying suction to the MAP sensor when I read your reply.
The wideband is wired via the fuel pump relay as per the Microsquirt drawing.

I really appreciate your input, thank you.
