Hello. I wrote before about my problem with Maxxecu street where injectors won’t open all the time when cranking the car. I have a digital hall sensor and have checked the trigger ocilloscope, but can’t see anything wrong… I only using the crank sensor, no cam sensor. I have tried different settings for the fuel, like sequential 720 without sync and sequential 360, but its still the same. Sometimes the injectors open and sometimes don’t, mostly don’t. I have some pictures of the trigger oscilloscope and the fuel settings. Someone has a good idea what it could be?
Regards Fredrik

Have you followed the steps on this page:
https://www.maxxecu.com/webhelp/solutions_and_faq-trigger_problems.html
Does the "In Sync" parameter become 1 and stay 1 while cranking?
I think the MaxxECU wants to run sequential, and thus requires a home signal. It has many different ways to generate this (MAP signal on ITBs, single pulse on a distributor or cam, etc).
Otherwise I think your only hope is to use a 360 degree mode (ie, fake being a 2-stroke), or use the Advanced Trigger Option for Unsynchronized Start set for "Enabled, Starts in Wasted Spark, and keeps running if CAM is missing".
Note that they warn this is only a "limp home" mode, and could damage the engine if used under load. So I think your best energies would be spent creating a home signal.
