Just got a speeduino installed on my 92 1.6. I/E/H. Finally have everything tuned up, runs great, pulls harder than my old stock ecu did. the only thing I cant seem to nail down is the startup. Car starts after about 5 secs of cranking, when the car was on the stock ecu it started up after about 2 seconds of cranking on nearly the first start instance. if you have a perfect start can you post up your starting settings? Lets use this thread to share a topic that is often not talked about.

IACV at cranking settings
Idle PWM - Cranking Duty cycle
Cranking settings / timing
Warm up enrichment?

Allot of these settings vary heavily from car to car, and also depend on environment (temp, barometric pressure, elevation, humidity, etc) so copy and pasting other people's settings might not give the results you want.

However, on that note; I've heard having a starting pulse delay and a hefty starting pulse yields good results.

you should post a copy of your tune. FWIW, I would get great cranking on stock ecu and meh / soso on my 1.6 on megasquirt where as my friends 97 I was tuning had phenominal cranking. I upgraded to ls coils and my cranking issues went away. Have you tried swapping your coil for a new 1.6 coil?
