Hey guys I need a little help I have 2008 vrscaw 1250 I bought xieds I can only find where to plug in one end where does the other end plug in, they are supposed plug and play.
You have to unplug the wiring harness to the O2 sensors and put the xied's inline. One is under the seat, the other is under the left side radiator shroud. There is no "other end". Pull the plug apart, stick both ends of the plug on the xied. It's about as simple as changing a light bulb.Hey guys I need a little help I have 2008 vrscaw 1250 I bought xieds I can only find where to plug in one end where does the other end plug in, they are supposed plug and play.
They help a lot.Mine are in shipping, can't wait... never liked the heat, especially in the traffic.
Running topless with Vmods.... I'll bet you a beer your bike is lean.I have them on a 2008 vrscaw , It makes it dun a little cooler, it richens up the fuel it up a little, I have vmod mufflers and run topless, I love the way it runs like a scalded dog.
And I'll bet you a beer it's not running lean. If it was lean, he'd get a sensor out of range code. If there is no code showing, then it has to be at 13.9:1.Running topless with Vmods.... I'll bet you a beer your bike is lean.
There is no way Xieds can or will make the needed adjustments to the fuel system for your setup. Ive read some members post about Xied and it the best thing since sliced bread, now you have to ask yourself if this is the hot setup why are the rest of us NOT using Xied?![]()
Dyno the bike and have the A&F checked, then post the dyno sheet for us all to see.
Good luck Greg
What I have is simple logic. On any bike with O2 sensors the ECU varies the injector pulse to maintain a specific voltage from the O2 sensors, that's how the AFR is set. When the ECU can't achieve that target voltage, it throws a "sensor out of range code". It says that in the service manual. Xieds are voltage dividers, they reduce the output voltage from the O2 sensors, so rather than hitting the target voltage at 14.7:1 AFR, it happens at 13.9:1 AFR. You can achieve the exact same result using a SERT and bottoming out the O2 sensor bias tables.He is running topless and Vmods so yes he will need a tuner with this setup. If this setup didn't need a tuner some us here have wasted a lot of money.
Malcom what changes have you made to your bike ?
Have you had it dyno to see where the A&F ratio is at?
If not you are slinging crap on the inter-net with NOTHING to back up your claims. :deal:

In either case, the ECU is looking for a specific voltage from the O2 sensors, and will adjust the mixture until that value is reached, if it can't achieve the target value, it throws a code and goes into "limp home" mode.
It's a relatively simple method of holding an AFR regardless of atmospheric conditions. Note that it only works in closed loop, in open loop the ECU reverts to map, but there is an offset table (I forgot the name) that alters open loop fuel delivery based on closed loop adjustments.
Everything I've related is is available right here in this forum, it's by no means new or unique information. The pros and cons of xieds have been discussed at length. I decided to try the xied's because I was very dissatisfied with the PC-III I had, and it troubled me to give up the limited self tuning ability built into the stock ECU. My bike runs far and away better than it ever did with a PC-III and a downloaded map.
Now tell me why I'm wrong. I'd be very interested in any information you might have.
i must have missed the part where he had a turbo on it....................This might work on a stock bike but not one running topless with Vmods.
Still looking for that dyno sheet
Have you read anything I've written? Cause it seems like you've missed the entire point here.The ECU doesn't have the ability to make the changes need for Vmods and topless.
Again what changes have you made to your bike ? and where is the dyno sheet ?
