Default elec. guys, need help once again....

So heres the deal... I recently installed the injector harness in my car for the emanage (yes , i know emanage ). Well what happened when i tried to add fuel under boost via the boost sensor (im using the signal from the apexi avc-r boost sensor)? The car cut off... again and again.... I've checked the wiring 5x its perfect and its all soldered. I put it all back to zeros and did some research, all hyundai ecu's have this problem. I disassembled an ecu and compared it online with other ecus (ones that work with the injector harness). Most ecus consist of the ecu grounding the injectors and firing them , they contain a bypass diode in case the ground fails it will bypass and let another ground through to prevent damage. The diode also prevents feedback from the injector signals lines. Well my ecu has no diode, just transistors to fire the injectors. Radioshack only sells one 12volt diode... Im thinking about trying an led (which from what i understand is one way) inline with a diode (which is also one way) to prevent back feed then add the emanage signal to the line. Any thoughts? That should work correct? Thanks in advance, it would be nice to be able to fine tune using that feature....
