Injector Resizing - AEM EMS?
 

Hey folks. I have a 90 miata with a 97 motor in it, and have been running it NA for a while. So therefore, I have the 220cc injectors in it, and I'm currently half way through my turbo build. I just put my m-tuned fuel rail in, and the toyota supra 440cc injectors (had them in my last build with a f/ic). What do I need to do on the AEM EMS side to compensate for the new injectors? I think my fuel chart at the moment is pulse based.

Thanks for the help :) If everything goes well, I should be up about mid week.

I'm not the guy to ask but; I just rescaled my map by small percentages until I hit the AFR figure I was looking for.

Thanks for the reply. I figured as much, but was hoping the EMS could just auto scale itself :p

Not that I know of :giggle:

right click on the fuel map(the one with all the numbers) On the bottom of the options it should say "change injectors/pressure" click that and then change accordingly

That's a cool little utility. Any idea on what the max CC at what BAR I enter for the 1990 Mazda RX-7 red top injectors? (460cc). I have the specs for my 97 injectors.

Thanks for the help!
