Looking to test a known good ECU

I'm having an intermittent hard start issue on my e30 cab.
Never fails to start, but 1/10 times, it takes two or three tries before it fires up, at which point it runs absolutely perfectly.

I'm leaning towards injectors or ECU, given that the pump and cps have been replaced. The FPR vaccuum hose doesn't smell of fuel (therefore not necessarily bad), and i can't really tell with the oil dipstick if it smells enough of gas.

If someone has a good ECU i can try out for a week or so, that would be wonderful. Happy to compensate.

It's a (euro, if that makes a difference) M20B25 -> I believe this was the 173?
