fuel controller question

[yamalube]

Is a fuel controller needed when you put just a exhaust on. i want to put a hauck slip on ny 09 xtx and i am kinda scared to get engine damage from having not enough fuel. and if anyone can tell me anything about co adjustments that would be great. and when you add a fuel controller is a o2 gauge needed or should the controller come ready with the right settings[/list]

A fuel controller is usually needed when doing a full exhaust change(header and muffler) and getting an intake mod. If your looking for hp, you should change the header. If I'm not mistaken just adding a muffler may lose you power because the stock header is so restrictive. I tried the co settings before my mods and honestly saw no change. When adding a fuel controller you must get a map to adjust for your mods and an A/f sensor is not needed but I'll be installing one to help fine tune for my mods. Hope this helps. I'm sure others will chime in.

Ya i just want a slip on for the sound lol not the performance. thank you for the feed back and should i be safe with just a slip on and no other engine mods without a fuel controller?

I'm pretty sure you should be. If you were changing the header that would be a different story.

Don't worry, you'll be fine without a controller.

With just a slipon, a fuel controller is not required..you should be able to pick up 2-4hp...depends on what slipon though. You don't need an o2 sensor guage to run a fuel controller...it's a nice to have to monitor your A/F readings..but not a must have item..unless you are boosted or have more mods.

Just out of curiosity... I have an intake mod and have a mid-range "popping". Is that a real big issue? Or can that hurt the motor? I'm guessing it's a lean spot,correct? Will a controller clean that up? And does it (controller)add any hp with intake mod? Thx!

Is the popping on decell or accell? Deceleration popping is normal on these.

Its at a mid-range, steady, tight trail speed when I'm being easy on easing into the throttle. (tried to put into words best i could)
