If the ECU does not have knowledge of 360 vs 720 degrees, you can still run the engine. However it will not be sequential, as it would squirt when intake is both open, and closed.
ok, i fully understanding now.
let's say mitsubishi 4/2 tiggers. it is still enough if using only one slot cam signal?
i found 4g92/4g93 cas is 4/1 slot.

which is better? 4/1 or 4/2?

on your 4/1 sensor we are using 4+1=5 marks, not just 1 mark

on 4/2 sensor we would be using 4+2=6 marks, 20% more marks?

but we really need to try the 360 sensor once I have some time to prepare it. My race is in 10 days, I hope to have more time after the race.

Hey Matt,

You were asking about when launch control feature would be available - to be honest I have no idea :( For that to happen someone would have to work on that and I doubt that would be me in 2017 :(

done some testing just now. i use standard nissan ignition coil with distributor. first start couple month ago with individual honda k20 coil. i wonder why trigger offset is 365 (nissan coil) instead of 630(k20 coil)?

tomorrow will do some wideband tuning, hopefully all running good. if all ok, this ecu will be installed at nissan GA16DE by next week.

here is our old rusty race car. :D

Could it be that the signal is inverted and the other coil fires on the opposite signal front?

http://rusefi.com/wiki/index.php?title=Manual:Flexible_Logic

I read throughout and not 100% understand. Let says If I would like to control my neo vvl, intake is open at 5500rpm and exhaust is at 6000rpm. Got two solenoids that I believe same as Honda VTEC, on/off type. What should I figure in tuner studio?

Until before recently you could only console, not TS for FSIO. Pretty recently text fields have appeared in rusEfi TS project so see http://rusefi.com/wiki/index.php?title=Manual:Flexible_Logic#Case_study_.235:_solenoid_exhaust_cam_actuator

I've aslo added this example into https://github.com/rusefi/rusefi/blob/master/firmware/config/engines/mitsubishi.cpp so you can invoke set engine_type 16 in order to try it.

from my understanding, i just figure it out at console and nothing todo with TS?
i trying to figure it with shift light function, looks like it suitable with my neo vvl solenoid.

Are you on recent version of firmware/TS/console?

Please post your currenttune.msq once you make progress or if you have questions.

That means it has failed to update firmware :( Why it has failed I do not know. Try rebooting PC and replugging USB cables?

Random guess, have you tried STLink --> update firmware as shown on this wiki page?

It appears it failed on the first byte it attempted to write. I see it notes " is not erased, verify the memory protection"

Is it possible that you have selected a memory protection feature and have locked up the memory on that board. I have not looked into memory protection, so I do not know for sure, but you message does seem to indicate that is what you have done.

I'm ignorant about how to correct it if you activated the security features. It's even harder for me as I did not preform the sequence which got it like this. It's probably a $12 mistake.
