Who's using XIEDs instead of a tuner and why?
#21
I've had XIED's on three Harleys...a 2010 FLTRX, a 2011 FLHTK, and now a 2012 FLHRC. The first had a 103 Stage II kit, the second a 103 with Stage I, and the last a 103 Stage II. All had appropriate HD flashes to amend the several ECU tables. All ran lean in closed loop until I installed the mod. I noted that via spark plug color and cylinder deposits (I have a borescope).
They work very well in closed loop when the O2 sensors are working...up to about 40% throttle and 4K rpm. Very well being they ran a little richer, maybe a little cooler, and with no pinging on quality fuel. It takes some mileage (= various engine load configurations) to adjust the fueling to the mod's O2 sensor voltage alteration.
After installation I believe it helps to run in any engine load range that may initially seem rough to modify the fueling there more quickly.
I can't confirm the claim that they will enrichen open loop fueling, but they certainly don't seem to harm.

why ?they were cheep.used em for over a year,with and without pipes and ac,they were an improvement but...the bike would still get too hot and start to ping even with just slip ons,it did take longer and hotter weather.went to a pcv with fuelmoto mao and never relized how bad it was running,no more ping,heat,stumbling or surging.for methey are an ok alternative to a tuner if using mild slip ons only.

Very good. I recall him mentioning a number in a conversation a few years back. I've done, and had done, early version aftermarket fuelers, PCIII, Cobra, Fuel Pak, DynaTek, on several motorcycles without O2 sensors. Nothing newer that self adjusts with wide band sensors, or has a way to capture real-time info. Many extoll their virtues. I can't claim otherwise.
But for me, it'd be an endless toil of running, adjusting, running, adjusting. I've had enough of that behavior for work and other enterprises. I don't need another project to consume my time and energy as the motorcycle is an escape from chores. If my current ride continues to run well with a HD Stage II flash and the XIED's, then that's plenty good enough.

Op: you must be totally confused by now.
Do yourself a favor and go to the nightrider website and do some honest research about XIED/ VIED's. It's all there.
I'll never bash Steve Mullen's products - they do exactly as they are designed, they do it well and are bullet-proof.
What they don't do is improve performance. They weren't designed for that.
If improved performance from a Stage1 is your goal, you need a tuning device. There is no substitute and you'll never regret the investment. Use of a tuning device will not only deliver improved power but will also retain good fuel mileage.

Glad I spotted this thread. I have a cat delete and American Custom muffs with a stock AC. I don't doubt for a minute that any bike, total stock or full stage 1, wouldn't benefit from a full tune job. But if the stock lean tune is satisfactory performance wise and you just want to richen the afr a bit, I think the XEID's are a very cost effective solution that will not hurt the bike. I talked at length with Steve Mullen and he's an incredibly sharp guy who knows his stuff. I'm gonna go the XEID'S route for now and at least know that the mild richening will keep my motor safe and running happy. If I should happen to win the lottery or get a surprise inheritance, I'll buy a TTS and have a hot shot tuner max it out for me. Gotta be realistic with the funds here for now.

Need some advice from you guys. I had FLSTC with Rush full exhaust without cats, Fuelmoto SE intake and Xieds. Ran great and cooler. Now have 2012 Triglide. It's brand new so I'm going to get a JES oil temp dip stick and see if the temps are too high, which I assume they will be.
HERE'S THE QUESTION....Since I like the sound of the stock Tri Glide pipes, would adding a SE intake and Xieds help the temp problem if I keep the stock exhaust?
