I would not say I am paranoid. More like frustrated. It seems much like trying to get a loved-one to see that they are abusing alcohol or something, with no success whatsoever...

If you would only acknowledge that, in relation to our current EFI, these things mis-tune a properly tuned engine and merely serve to lessen, in some respects, while enhancing in others, the mis-tune of a mis-tuned engine, I would feel like it has not been all a waste of time for me.

 

Glens you haven't said anything yet.&nbsp\\; You keep alluding to a problem, but never clarify exactly what it is.&nbsp\\; How am I to take you serious when my Bike runs better now than it ever has?&nbsp\\; Get specific Man, stop beating around the bush.&nbsp\\; What exactly is the horrific problem that the XIED is creating.&nbsp\\; I saw you endorsed the IED, so the problem must be only within the XIED.&nbsp\\;&nbsp\\;
&nbsp\\;
I'm listening, please tell me.&nbsp\\;

Crusier did you try xieds without the rk3909.
I am wondering if its worth putting on now since
I wont be doing cams and sert for another year
and a half.

 

Fix this FORUM! I cant upload test results.

No, I didn't.&nbsp\\; I figured with the increase in fuel from the XIED it would be better to run the K&amp\\;N.&nbsp\\; If you want to keep it stock get the IED.&nbsp\\; They really do improve the stock Bike quite a bit.&nbsp\\; I was so happy with mine I turned down Steve the first time he asked me to test ride his XIED when it was in the testing phase.

 

The ECU assumes its VE tables are properly populated. The tables reflect the amount of air moving through the engine at several hundred throttle/rpm combinations. When running closed-loop it targets a set voltage from the O2 sensor. Whenever that voltage is missed, it knows its fuel calculations, based in part on those VE tables, were incorrect. It sets a factor for the entire VE table to effectively change all the settings in the table by the same amount so that future calculations should be correct, wherever they may occur.

If your VEs are actually right, like with a stock bike or an all-factory stage 1 w/download, by using an IED you effectively shift all the VE entries everywhere. You added fuel while closed-loop. Now the ECU will correct what it understands as its mistakes and add the same proportion of fuel while open-loop. You did not need that extra fuel there with your stock bike. You have thrown the tune awry.

If your VEs are not right, like when you put mufflers, pipes, A/C on, in any combination, without somehow correcting the VEs for them, you are not tuned right. While closed-loop the ECU will probably get itself worked out fairly close in places, but the VEs-factor will not be correct anyway, even if it were stable like it should be, but most assuredly is not, so you still are doing unknown things open-loop, compounded by the error you have in the VEs for closed-loop. And they will vary by the amount of error you most recently had while closed-loop, which will vary in most every case. So your open-loop VEs errors will fluctuate.

Those are two factors you are now personally working with.

The O2 sensors we have can work reliably down to almost 14:1 AFR. The regular IEDs themselves respect that. The XIEDs do not. They make the O2 sensor spend too much time in an area it was not designed for and cannot work reliably there over time and/or temperature. That is just the way it is. Even while they may be working okay with the sensors, they are throwing the VEs-correction even further out for open-loop.

 

I'm outta here until it's fixed. Period.

 

If you had the option of SERT with Canned Map or XIED. (aside from money) What is the better choice and why. Assuming bike is stock now but going to 103 and cams in the winter (4 months away).

Thanks

Looking at canned map 202td.

 

My XIEDs are for sale, if anyone's interested.&nbsp\\;I'm running a TFI now, with o2 eliminators, so I don't need them.
