i dont think the ecu will have a problem but it will be harder to pin point your height presets with the larger volume. so it may adjust many times to get it where you set it too...unless you run some type of valve to each line to restrict the speed in which the air is distributed or removed, Just hardline 3/8 or even 1/4 that way the ecu will be accurate and precise with less need to keep adjusting itself to the presets. just my2 cents
