I don't have the popping and the TFI did mess up the idle.

OK am I stuck with it and does every one with this problem except it?

This has created a new gadget industry.
Is that the intent of the legislators?

smitty901

TFI did not mess up idle if you have an idle problem then there is some thing not work right with the bike trouable shoot the problem not the bande

Has your bike had the download update done mentioned in servcie bulleten 0903?
It should have but some time these things get missed. This update did make bike run a bit smother when rolling on fuel.

Is the bike still in warranty or have you documented the problem while covered if so make dealer fix it.
They do not all do it, yours has a issue sometime is lose broke or malfunctioning.
A proper running bike does not surge does not idle bad or any thing else.
All air cooled engine made in last few years are lean they are designed to run that way and do. They suffer a bit of heat gain and lose of power from this.
That does not mean they run bad.

As Smitty mentioned the TFI cannot mess up the idle unless you are running it so overly rich above the recommended settings that it fouls the plugs.

Your problem lies elsewhere and being you have been the repair business 52 years relates to a history that should tell you that the modern Harley fuel injection system can be altered by altering the pulse width of the injectors like most fuelers are capable of, so how did this mess up the idle?

I would suggest looking elsewhere for the problem rather than blaming the TFI for your problem.

You didn't mention if you checked for intake leaks yet???

"This has created a new gadget industry." Not a great way of looking at modern technology. One must understand the modern technology before condemning it and Techlusion has been around for many years in many fields besides bikes with excellent results.

I'm not blaming the tfi for the problem. The plugs were not fouling with either the 14XIED or The SE Fueler. The idle with -10% or 0% or +10% on the fueler was not as stable as with out the gadgets.

The springer thread notes the same on the idle.

I spent a lot of time testing riding and recalibrating with little change in the performance (smooth performance), over 100 miles and several changes.

It's gadget free now, but I'm not satisfied

Smitty, I did have the dealer do the torque thing, now it pings slightly and I use 93 octane

I'll have a conversation on the subject tomorrow with the tech at the Harley dealer.
They road tested it after the change, maybe they thought I was going to race it (G)
I say another road test by the dealer Tech is in order.

I agree if the bike has ping with 93 then it will ping with 91 and thats not right. The bike should run fine on 91 and thats what HD owes you.
This is why I urge riders to wait on mods make sure the bike runs as it should first then go for it. Once in a while you get a bike that has a lose wire a bad connection any one of a hundered thing that just is not right and the bike will not run as it should. This does not just happen to HD.
I hope your is something simple like an sir leak.
Stay in touch let us know what your find

Did you check for intake leaks? How did you do it?
