Hey all,

Has anyone had any experience with using these O2 sensor inline fuel enrichers?

I have a 2014 Sportster with Screamin Eagle exhaust looking to to get a new hi flow AC, and understand that it will make the mix quite lean due to the extra air as I understand the stock AC restricts the intake somewhat. 

My question is that the ViED's will only enrichen the mix during closed loop, howver if the point of getting the new AC is to get a little better performance, the open stage is where I want the HP increase to take off and at a heavy throttle, so does this thing help at all during open?  it claims it can due to EMC adaptive learning, however I didn't think stock ECMs did any learning...?

 

If it can't what suggestions are out there for a cheaper way of correcting the mix for stage 1 without going all out on a SERT/PCV or TTS...

 

Thanks

I had the XIED's that make closed loop 13.8:1. They work great, excellent with just slip on mufflers but got a little poppy and hot with a aftermarket air cleaner.

I got powerhungry and got a Powervision, IMO if you can afford it, do it right from the get go... it's like a new bike now!

Save your money and buy a tuner . You,ll have to go that way in the end anyway . IMO .

 

Power Commander 5 (PCV)  ( Edit - must be hungry , took the bait G.T.  

Thanks guys

If I go ahead with the pcv and no autotune module does the PCV act as the ECM making the original kind of redundant or does it tweak the signal to the ECM ?

Also if the exact map is not available are you then forced to get a dyno or is there a tuning mode to it that allows it to learn( without the auto tune )?

Looks like the pcv is the way to go as tts is locked to the bike atleast this I can reuse and take off if any warranty concerns from dealer occur.

Cheers

Thanks
I'm confused as to if it flashes the ECM why does it need to remain on the bike ? I thought if you removed it there would be no trace of the tune and bike would run as stock...

If your going to the trouble of buying a ECM tuner and not the Xied's you can get a TTS Mastertune that will do more for less than a PV unit.

Cheers looks like this post has now become powervision vs power commander v vs TTS


I understand TTS & PV (powervision) remap ECM whilst PCV (power commander V) is installed in line.
If within warranty sounds as though PCV is the safe bet.

Hi art,

I ran the xieds for around 20000kms with open se air cleaner and cycle shack slip ons on my wide glide, the one thing i noticed immediately was it smoothed out slow speed riding, 10-50km speed, leaving residential streets, carparks etc

They wont stop decel pop, may reduce a little, hard to tell if any real performance gain

Thanks

I used the IED's quite successfully until I "discovered TTS "( kinda like Smirnoff Vodka haha...)

So TTS gets my vote for ease of use , but the XIED wires are the best bang for the buck if you'll make no more changes

My 2007 Softail Custom is still running around quite well with them installed and I sold that in late 2007 !!

The warranty deal here in the USA is really screwed up today. HD has been voiding warranty any chance they get. If your bike fails and is modified with any parts even there own parts that are non smog legal parts they void the warranty unless you fight them. The dealer will not do it for you. So if you want to keep the warranty leave it dead stock and any dealer that says it's OK get it in writing and say your prayers.
