glanza s ecu doesnt work with uk n/a's wouldnt run, nor would a corolla one when i tried it.. Re fuelling, ive only ever seen one n/a checked that was running glanza s injectors and a corolla inlet and it was super lean lol..16.x:1-17.x:1 AFR's lol..n/a's should be around 13.0:1 on WOT.. i had a set of glanza s injectors but never fitted them, side by side with standard n/a ones, the feed holes were tiny, looked like pin pricks comapred to the standard ones, i know also that the glanza s runs a different fuel rail and reg aswell, so i came to the conclusion that it must run higher fuel pressure, or the map on the ecu is completely different.. if you were ever gonna change injectors on an n/a drop corolla 225's (they are yellow ( and i think they are 225s) or FTE ones, but thats probably gonna be over kill
