ok people get this confused all the time with the safc and i guess emanage too. it can trim 50%, ooook. so you put in 480cc injectors and set it on -50%. 480cc x 50% = 240cc. so essentially it could tune 540cc injectors perfectly on a stock ka ecu. the ecu will do some minor adjustments to get the idle right so im sure 550's would work ( 550 x 50% = 275). so its 50% of whatever size injector you put in it can take away to get it around the stock 270cc size.
im using sr s15 480cc sidefeed injectors at -44% to get the idle right. im also boosting 14psi on this which should be maxing them out.
