Ah, then also 2 squirts so the cycle doesn't matter. ;)
If I set it to 2 squirts it would make my req fuel 4.4ms is this too low?

4.4 may be marginal, but it depends on your injector size and latency, relative flow for the engine, fuel pressure control, and the engine's needs. I have run up to 8 squirts on engines with typical injectors, but not ones that are grossly over or under-sized. You can calculate if it should work (everything EFI is math), but simpler is to just try it to find any limitations, then deal with those to the extent necessary.

Hi All,

I'm having sync losses at high load
I have attached the tooth logger output
There a slightly taller tooth after the missing tooth
Cps is a ZF Cherry Hall type sensor,
Car doesn't like to rev over 2200rpm in 3rd gear, but 1st and 2nd it revs nicely without any sync losses
Ignition - Wasted COP
Injection - Semi sequential
Any insight about this will be nice🙂

+1, you're stuck with the Hall signal polarity, so it's the Trigger Edge setting that's backwards. You want to read the more-stable falling edge signal of the physical tooth, and without signal drift (looks to Speeduino like a wide tooth) in the gap of a missing tooth. TL;DR - whatever Trigger Edge is set for, try changing it to the other. :lol:

I would suggest you are not getting enough advance!
generally speaking, full advance should be in around 2500-3000 rpm

Can I suggest, as a way of reloading your table should you want to, that you export the current table, and then try the link below to import another.

The import/export buttons are the white arrows on green background, available on all three main tables.

Hi
I tried the spark table generator and rebinned to my axis
It did become much better
Now I'm really sure its related to rising rom vs advance
Changed firmware to 202012
Found techo sweep is not working 😬

Hi
Does anyone has Injector charactoristics of Injectors 0-280-150-715, 154cc/min standard injectors for m40b16/18,M20b20
Searched everywhere couldnt find, i could only find the flow rates only
