Re: Two stroke Efi (#14)
both TS and console on TTL
discovery mini usb is useful for firmware upgrades, but there are other options if you are looking for another option - but I am only using the mini usb on the discovery.

Re: Two stroke Efi (#14)
I´m using usb on Frank now, finaly is working. When i start engine after few seconds i have this warning "Protocol error" . When this happens ts come slow and sometimes loose connection.
Maybe noise from generator/spark coil/vr sensor?

Re: Two stroke Efi (#14)
Have a problem with fw, PC15 (Output for injector doesn't work) if i choose another pin and make a shunt solve the problem (With this i can test Frank board/ output is ok). The same happens for trigger input and Clt, another inputs are working. Configutation "set_engine_type_29" doesn't work anymore.
Need help.

Re: Two stroke Efi (#14)
PC15 problem: if it has worked but does not work now, I'd try a replacement discovery. If you are running fresh software maybe try older version from 6 months ago? See https://svn.code.sf.net/p/rusefi/code/firmware_archive/
CLT: need more info
what are
analoginfo
and
tempinfo
outputs?

Re: Two stroke Efi (#14)
I´m using a old version only to test the cdi ignition. cdi is triggered with rusefi pulse.
Re: Two stroke Efi (#14)
CDI stands for capacitor discharge ignition?
Do you have a scheme with part numbers? What are the pros and cons of such solution? Does it need a magneto? (It seems to be rectified?)
Do you use O2 sensor in this setup? As far as I remember, older models of JAWA required adding oil to gasoline for lubrication purposes, but that could kill 02 sensor?

i´m using this cdi
cdi is better for high rpms, spark "quality" is different , two stoke engines can run 20k (in my case maybe 14k).
Yes, i need a magneto, cdi need +/- 200v to charge the capacitor, rectified with internal diode, (see D2 and D4)
I used o2 sensor once but it´s not easy found a good location to install . The exaust it´s a important piece on 2 stroke engines.
...yes, i need oil on gas to lube cranck bearings. Oil and fuel are injected mixed. (+/- 2% oil). all two stroke need oil on gas (except one in development on newzeland)

That is a sweet circuit simulation thing. Thanks for the link.

Re: Two stroke Efi (#14)
What is the status of this project? Finally you used MAP or TPS for engine load?

Re: Two stroke Efi (#14)
Need some help to configure tps on this version of firmware.
I have tps adc value changing when i move throttle but gauge doesn´t move and also have tps error.
What i´m doing wrong? thanks.
Please take a look on this vídeo.

Re: Two stroke Efi (#14)
TPS is now measured in volts not ADC I believe, you would need to calibrate again.
Welcome back!!!

Re: Two stroke Efi (#14)
Did it again and doens´t work for me . Also tried in pedal option and gauge doens´t move. Tried fired up engine and the "pointer" only moves in the lower line.
second question. Why the VE TARGET table is not disponible? (next step -> autotune)
Thanks.

Re: Two stroke Efi (#14)
Please record a video, please attach logs. I recommend https://getsharex.com/ for screenshot videos but just you cellphone would also work.
