Re: Help to choose right setup

As far as I understood you plan to build ignition with "wasted spark" configuration. What other devices you plan to control on your engine using SECU-3 unit?

Re: Help to choose right setup

Do you know which type your tachometer is? Low voltage or high voltage input? If it is connected to the ignition coil, then it is high-voltage input.

I guess it is low-voltage input.

For wasted spark ignition control and output for tachometer you need SECU-3T unit and 3 BIP373. You will reassign any free SECU-3 unit's output to HALL_OUT and it will output pulses for your tachometer.
IE and FE outputs are high-side and 12V, others are low-side and 5V.

It is a throttle position limit switch. You can use either simple limit switch or TPS.

Yes, only one.

Correct.

No. There are a lot of wiring diagrams for SECU-3T unit on the our site. Take a look of them http://secu-3.org/wiring-secu-3t/?lang=en If you need, write your own diagram and show us, so we can find possible mistakes.
Also, please read installation manual http://secu-3.org/installation-manual-secu-3t/?lang=en
Our site is fully translated to English.
