Good stuff man .

Those things won't do crap for WOT performance.. They might fool the ECU into adding fuel in the closed loop (will run cooler but kill mileage) and some of the might carry over to the open-loop through long term fuel trims but you'd be better off buying a real tuner and having it done right.

Check it !
Product Answer Approved
An answer to a question posted for FL-AF-XiED-17 has been Approved for display at Nightrider.com Performance Products!

Thank you for taking the time to provide a question or answer for this product.

Please do not reply to this message. This is an automatic email from Nightrider.com Performance Products.


Question: FL-AF-XiED-17 when will these be for sale ?
Answer: Work in progress. The software used in the FL-AFXIED-17 is being updated to improve compatibility with the 17>Later bikes. It is more important to us to get the updates correct than get them onto the market quickly. So our approach is slow and methodical. We do expect to have the FL-AFXIED-17 available between Dec 2017 and 1Q18. Riders that are making exhaust and/or air cleaner upgrades to their bikes are not at any risk of harming the engine should them make the upgrades. The HD Delphi ECM is a closed-loop device with adaptive learning. This means that the ECM will recognize any changes in fuel mixture due to minor component upgrades and maintain the OEM fuel ratios. Contrary to popular myth, the HD fuel ratios are not lean. These AFR's are the same as your automobile. Do not confuse the heat from a 100+ CID engine with inherent tuning issue from HD. While additional fuel can improve the Riding Experience, it is not a technical requirement for these bikes.

These devices were never intended to replace an expert dyno tune on a heavily modified Harley. They were designed to improve performance on those bikes with minor changes like exhaust and air cleaner changes. You are not paying $400 for the device and another $300 or more to have it tuned. These are priced MUCH more conservatively. I have had success using these on several of my Harleys over the years under those circumstances.

I understand that completely Gunny , I actually posted that I did the same thing with potentiometers on a blown Ford ute/pick up don't know if you read that ,but modern ECU's are learning ECU's ,so may need more than one sensor hi-jacked or to be unplugged at the battery every time it works out it's being hi-jacked ha ha!

Why would you need one of these devices?

The seller/manufacturer stated (according to bablecookie) that the:

"HD Delphi ECM is a closed-loop device with adaptive learning. This means that the ECM will recognize any changes in fuel mixture due to minor component upgrades and maintain the OEM fuel ratios. Contrary to popular myth, the HD fuel ratios are not lean. These AFR's are the same as your automobile. Do not confuse the heat from a 100+ CID engine with inherent tuning issue from HD.

You're right, these only work when the ECM is in closed loop. WFO throttle initiates open loop ECM programming thereby ignoring the O2 feedback loop.

And no, they don't "kill mileage". I tune all my bikes to 14.0:1 AFR on highway cruise and routinely get high 30's to low 40's MPG, depending on speed and type of motorcycle. Killing mileage is when your cruise is in the low 13's.

Nothing wrong with that statement, it's accurate. The difference is that the ECM only does what the feedback mechanisms tell it to do. In this case, the XIED alters the feedback mechanism to the ECM so the ECM thinks it's at 14.7:1 when it's actually at 14:1 (give or take). Since the ECM things everything's fine there's no compensation to make and you go on your merry way with a slightly cooler and slightly more powerful motor.

Also, these devices are NOT designed to compensate for anything more than Stage 1.
