Just curious, why are you just changing the filter? What a you trying to accomplish by that?raptor07 said:I just bought my 07 Raptor 700R GYTR and am not sure if I need a programmer box if the only mod I am doing (at this time anyways) is a K&N filter??? Thanks in advance for your replies.
Okay so if i read this thread right than Im running to lean on my bike than huh, I put a new filter(uni) and pulled my sparkarrestor in my exhaust. So if I read this right than this is Bad?mws said:In my opinion, yes.
The FI is already on the ragged edge of too lean to provide minimum emissions (hence the glowing head pipe syndrome). The stock system is open loop - it does NOT have an O2 sensor or any other way to provide feedback to the ECU to adjust itself for changes, so any modifications you make that actually do improve airflow will result in an even leaner condition. It's not going to blow up right away, but it will be running lean so temps will be even higher, increasing stress on everything.
Thats not what I was told by Fuel Moto! They told me that the bikes ECU will adjust for Types of gas (octane), air temp as well as elevation. Guess they are wrong huh?mws said:In my opinion, yes.

For anyone considering doing any intake or exhaust mods the very first thing to get is the controller IMHO once you have that then your set for any other mod you want to do, that and just the controller, removing the air box lid and pulling the baffle out once tuned will wake the 700R right up and make it a lot funner to ride while your saving up for the high flow filter and exhaust system of your choice :grin_nod:
yes there is.....the stock machines run lean in areas. If you go with the PCIII you will also feel the difference of running the accel pump patchraptor07 said:Out of curiosity, is there any power at all to be had just from a controller?? assuming everything else is stock (stock filter with air lid, stock exhaust).
Exactly...same with the pcIII. there is an ALL STOCK map that adds fuel....and actually adds quit a bit in some spots for a STOCK machine.raptair700r said:On the instructions sent with my Dobeck Gen 2 it says to run 3-7-2:30-9 for all stock. I havent heard of anyone on here running a dobeck with no mods, but with it running lean stock it has to help somewhat.
