consider this is 2nd project, my chasis is kia carens 1.8 swap with nissan engine.
at first it was with cvt transmission, but it cause many problem with standart ecu.
neo vvl not working if not install with full engine and dashboard wiring harness.

i change to manual transmission and ecu was swap with ms2 with 4g63 cam angle sensor.
for now i prefer it running with standard 360 slot cam angle sensor.
i can provide trigger pattern in this weekend.

Do you have pictures of both sensors, complete units? If these are interchangeable I wonder if one can use Nissan sensor on a Miata?

Left is 4g63 (vr4), right is nissan 360 slot. Still need to modified the plate, if not it not touch the camshaft.

I guess let's begin without the 360 channel, I believe sync works based of the 4 slot?

Yes, please log only 4 slots as first step. Please select 'custom skipped wheel" total=4 skipped=0 while doing that.

What year/donor is your sr20ve? Want to name this trigger properly.

will this 360-slot thing allow to track efficiency of each cylinder and measure instantaneous acceleration? just wondering how the whole thing looks like - the trigger and the sensor... at 6000 rpm it means a pulse each 2.7~µs - probably, not an easy task for a microcontroller?

360 on cam is only 3 times more work compared with a 60/2 on crank. We will see :)

Do not even try 4/0 custom wheel - it would not work right for sure.

Do you have any console log files? There could be useful info there.

Next time try enable trigger_details & writeconfig commands in console or "print sync details to console" option in TS. This would produce some helpful messages with synchronization progress details.

this whole line is what you see in engine sniffer in console, raw data for it.

https://github.com/rusefi/rusefi/issues/314 is an improvement idea which was not implemented yet. some battery for stm32 does not matter where it would be - but that's just an idea at this point.

today progress.

with nissan trigger setup in TS, no rpm sync.
with custom tooth setup it start for a 5 second, and engine stop if throtle if press.

i can start engine with standard ecu and log a trigger in console if its needed.

I've widened the expected cap a little bit. It was from 8.70 to 14.50 and it is supposed to sync on 9.69, 9.62 etc.

We do not need 360 slot data so far. I wonder if it starts on 4/0 because your trigger offset is 180, 360 or 540 off? Did you get a timing gun?

it start with 4/0 at 0 degree offset, but just a few second and engine not stable.
with nissan trigger no rpm sync at all.

p/s: no timing gun yet
