Assuming you are planning on the 'AFC hack', 550cc is a little on the large side. I'm using 500cc and the trim is pretty maxed out as with the AFC u can only go -50%. Can be done but I think u'll most prolly be runnig pretty rich even on max trim.

even at -40 % (minimial setting on safc) you could not lean it out enough to target a fair AFR at vac and Idle.
Just save up money and buy a hondata or another standalone and some 550's

I use my widebacnd to street tune also and currently my trim is between 40% to 45%. On 550s you'll be close to -50 but it really depends on the rest of your setup tho as its not going to be the same for everyone.

i am using 550's and a s-afc and i have a lm-1 wideband and at idle mine is set at
-15 and i have a 14:6 to 15:1 a/f and the rest of the rpm band is set at -25 so i can get a 14:7 a/f so 550's are not to big for the afc on a honda...

Assuming your stock injectors are 240cc, there is no way you would not be running v.rich with 550cc and those afc settings....It just doesn't add up. Something ur not telling us or there is something in your setup is very different.
99lspwr - My 500s are not RCs. They call them Grey injectors here....I'm not too sure who makes them
