ok, this is something I cannot find in search. What kind of relay? how? and where to get it or where to install it? This is what questions me now: if ECU still sends out 12v+ at all time (and this is why it is bad with ethanol), and I will still need a relay to do the job, what is the purpose to upgrade to new style injectors? How does it help the injector failure problem? It is mentioned in many posts that new style injectors will do the job, but never explained how.
