if your VE's are  at say 13.6, your AFR is set in closed loop at say 14.1 or  2.  Will the  ECM one day find the 14.2 or do we need to get it closer than that, so it will find  the ##'s we choose??
Thanks

In the end, closed loop wins.

in other words the gap i posed will get from 13.6 to 14.2 one day, or miles and miles later??

We're the VEs calibrated to 13.x, and then the AFR table switched to 14.x ( closed loop)?
Ignorance is bliss, and accuracy expensive. How much of either can you afford?

14.1 targeted close loop?  CAN bike?

If the AFR table was set to 13.6 and then the bike was tuned to 13.6 and then you set the AFR table to 14.1 it should be close to 14 .1.  If you are dealing with a lambda tune then 14.2 is the lowest that closed loop will go but if its anything else then you have to set the afr table to 14.6 and change clb to get different afr. The ecm has the capability of around 30% on changing the VEs in closed loop.  If you are only changing values in the afr table then you shouldn't have to mess with the ve table once it has been "calibrated" for you bike.

its a 2013 street glide. so no its not a  CAN bike  yes 14.1 iis target.

Thereason I asked was.  009 or 044 cals, .977 lambda (14.34) is the richest it allows you to run closed loop.  If the red line ins't in the cell.  You are running open loop.

You can change that with 'Closed Loop Lambda Range' parameters.

i used a 44 cal wondering if perhaps i should go to the  DUh 009 cal. seems bout all i would gain is a lighter wallet, but never know.

I am under the assumption he is using TTS from other post. :nix:  Maybe that's my problem.  I am assuming.

With TTS you cannot change the closed loop range like you can with power vision HDmanillac.  To be in closed loop you will have to set the afr/lambda to 14.3/ .977 as stated above.

....and this is dependent on which calibration.

When the numbers are bold in the afr table that is showing you a closed loop number the non bold is out of closed loop.

I am assuming you are saying that the VE's got mapped at 13.6.  Now you want to put this area in closed loop.

That's how a VE based system works.  You map VE's at a target and then set desired AFR's.  Most of the major tuner brands that use BB O2 suggest targeting 13.2 for mapping VE's and then setting closed loop area's to desired.  Your VE's are mapped and will never change.  So, changing the AFR table from 13.2 to 14.3 is close enough.

What you trying to do with it?   Did you get the 120/110 WOT dyno tune and now you want it tuned in the area you ride?

its tuned enough to ride it safely. now its got some miles on it and can finish tuning it.. it is prolly not to far off but there are some areas that will be dialed in a bit better..  WOT area is just one area that will be looked over a little more.

Oops, sorry. I thaught it was possible with the TTS like with the DPV...
