I Just installed my 550cc rc injectors with a dsm resistor box. I start it up and it doesnt idle. Seems to be too much fuel. Is there a difference in the stock honda and dsm resistor boxes? Im pretty sure I wired up the box correctly. Any suggestions?

 

do you have a basemap at least? if you're running your stock ecu then that's your problem. my 450's wouldn't idle with a stock ecu either.
