I'll see what I can do here:
- What firmware version are you running? I need that to use the proper ini file for TS
- You are generating a lot of errors. Looks like one exactly every ten seconds. No idea what's up with that.
- Your intake temperatures get insanely high. Over 200C.
- You are running off the MAF, but you have a MAP sensor. I suggest using speed-density algorithm
- Looks like your fuel-tune needs improvement/ is possibly non-existing
- Your ignition table looks super-conservative in the lower load cells

generating a lot of errors... i dont have no idea ...

intake temperatures ......... the next step of the installation intercoolers air\air water\air ...
in TS does not show 200C ??? and therefore may be error ???
I understand if MAP ON then MAF will turn off automaticaly ???
yes I use MAP speed-density ...
what should I need change fuel-tune improvement ???
what should I need change in ignition table ???

Thank you ...

10 seconds is the default warning error period (this is to reduce the noise in the console messages but also affect logs, I guess I should improve the code so that console period does not affect logging frequency) https://sourceforge.net/p/rusefi/tickets/323/

CUSTOM_SYNC_ERROR_2 = 6037,
CUSTOM_LOGGING_BUFFER_OVERFLOW = 6044, - comm issue not important
CUSTOM_OBD_SKIPPED_SPARK = 6045 - that's ticket #299
CUSTOM_TOO_LONG_FUEL_INJECTION = 6050 - that's really interesting, that's injectors duty cycle?!

as long as fuel algorithm is Speed Density MAF sensor could be just logged but not used for fuel logic

VBatt (white line) drops from expected 14v to 2.5 volts from time to time which causes duty cycle to jump to 400%

I wonder if a wire is loose or a poor solder or else?

2.5V probably means that it's powered from the USB port I assume is still plugged in.

Then you have a problem with your +12V supply or possibly your GND connection.

The GND plane can suck up lots of heat, you may need to keep your iron on it for a long time to get the GND plane to heat up. If you have a 40W or 100W soldering iron you might want to try that. More heat can heat up a local area faster than the typical 20W irons.

Hello again ...
How to make on RusEFI same signal I needed ... As in my stock ecu ... to make a tachometer work ...
Recorded two tachometer signals ...

The first is the original ECU original tachometer ...

The second video is RusEfi ...

rusEfi has two options for tachometer output:
1) dizzySparkOutputPin - This implementation makes a pulse every time one of the coils is charged. uses coil dwell for pulse width
2) tachOutputPin - This implementation produces one pulse per engine cycle. At the moment this implementation uses "pulse duration" setting for pulse width and this width is contant number of milliseconds, regardless of RPM

Looks like what you need is a way to make a 50% duty cycle signal which rusEfi currently does not support. Good news is that should be a simple chagne and I should be able to make this happen :) https://github.com/rusefi/rusefi/issues/476
