SECU-3 firmware should work with mentioned trigger wheel, but note that SECU-3 Lite has only 2 ignition outputs and you can't use full sequential ignition on 4-cylinder engine. You can either use SECU-3 Lite in semi-sequential mode or switch to use SECU-3T if you want full sequential. For semi-sequential operation one sensor is enough (reading of 12-1 sequences).




Thanks for your quick reply!

So, if I'm following you correctly, I could use it in a wasted spark configuration with coilpack, but not in COP (coil on plug) configuration?

Yes, you are correct.

Re: SECU-3 Lite ignition control unit

Hello again! I have another question.

With the given 24-1-1 (12-1) trigger wheel for Nissan CAS, how would you set it up in Manager?
If I got it correctly, lowest possible setting is 16 teeth. Could I use it as 24 teeth with 2 missing teeth?

I'm sorry if I'm missing something obvious, but I'm novice at stand-alone EFI and ignition, so please bear with me. ;)


Thanks,
Tomislav

Re: SECU-3 Lite ignition control unit

Sorry for that, I will publish SECU-3 Manager with ability to set less number of teeth soon. You will need to upgrade to v4.7 software. How urgently you need this?

It is not urgent at all, as I don't own SECU-3 yet (forum user control panel would not let me choose that I don't have SECU-3), and I'm only just at the beginning of my project, collecting info.
But I definitely plan to buy it, because it would be ideal for my application (under the condition that I can make it work with Nissan CAS).

If you don't mind, I also have a question about using MAP and TPS.
Is it possible to use TPS only for load input, or MAP has to be used always?


Thanks,
Tomislav

Yes, it is possible. I already added support of Alpha-N and I will publish update software soon for testing. You will be able to select between: MAP (Speed-density), TPS (Alpha-N) and MAP+TPS (mixed)
