those injectors are a problem
u really need to pull that MIL code and see what it is, that should have been step #1.
that ecu u bought is not a p13, its a p28/p30/p72 or maybe some cheaper non-vtec ecu that the seller added circuitry for VTEC, im interested to see if there is a Knock board inside that thing, pop the cover and take a pic.
also u can get a p13 for under 200 if u play your cards right. I would never buy one of those "hacked" ecu's because u never know what your actually getting.
