i have some spark plugs in my gsr they r the brisk i never had probelms before , but they turn black all over them even the tip not oil but like carbon powder. IF anyone knows how to fix it i could really use some help. I have had some people say that its to running to rich with the aem reg. and a chip ecu.

 

to rich..

 

Do you have a Gauge, whats the fuel pressure, did it start after the ECU was chipped? Basically turn the regulator to about 41 PSI, i believe thats the normal Honda Pressure. If it doesn't help return the ECU to stock or try another Stock ECU.
