Ok i have found sites selling 24lb injector upgrades and the new software for the e36 bmws, now i got to lookign at these injectors and they are just a bosc top feed injector. If this is the case i should be able to put the set of #24 injectors i have layign aroudn my shop that i had in an old 5.0 mustang, they are the same. and save myself 300 bucks and buy the chip seprately . after all it is an upgrade from the 19lb .
