Stock ECU with ITBs...
So I was reading up and ITBs would be pointless on the stock ECU because the AFM would limit the airflow negating power gain.
However I found the RX7 FC AFM mod from the NA models which flows much better.
So I was thinking if you combined these 2 it might work(Not as good as an aftermarket computer but when I can afford a good one I will.) with a sealed airbox.
So the question is would the injectors cope? An air/fuel ratio meter would be a good idea, can you jus put bigger injectors on?
Also dont tell me to put the money on Forced induction. I want to waste my money on ITBs.

I would say the 1600 injectors would easily cope but to be safe you could throw in the tan-top 1800 ones and still not affect idle etc.

You will be spending enough just to get itbs on there so you may as well do it properly

bigger injectors are a waste of time on a stock ecu'd normally aspirated 1600.
the mx5 runs PIG RICH at wot so leaning it out is a better idea rather than making it even richer. i run a leaner WOT mixture on my turbo than the factory NA tune, thats how stupidly rich it is stock.
itb's on thier own arent going to make a huge difference in HP that youll need bigger injectors.
people have to remember that a b6 1600 is no frekin honda! the head flow is crap and the cam durations arent right for high rpm like a honda motor is....
if your gonna fit ITB's then get a megasquirt.
its that easy.

AFM won't work if you actually want to be cool and run trumpets.
Just delete that part, get a link, and run open throttles like a mad c*nt. there's no point investing dollars in an ITB set up if you aren't gonna let them scream.
