k20a2 / idle ignition control range stuck on 20.95

Post by qbi » Mon Sep 10, 2018 10:30 am

vehicle: honda ep3/ k20a2/cai/rbc/dc4-2-1/oem catback
hondata sn: 026933-3305
kmanager: 4.3.5.0

hello. :)
my "idle ignition control range" keeps resting to 20.95 and i would like to be on default 5.
when i set various settings like 4,5,6 or 10, after upload it reads 20.95.
and it facts it at 20.95, can suddenly advance 20 at idle under load.
that can cause very "jumpy" ride at low speeds with no throttle.

twice when i was "messing" with idle control settings i was able to set to 5.
it was random success 2 out of 20 uploads.
and maybe it has to do something with this error, it shows only in parameters
at idle bar usually after upload.

Post your calibration and a datalog showing the issue.

Are you sure you are saving the calibration on the laptop with the correct settings? The calibration you have posted has the correct setting.

i don,t have any problems saving calibration. (so i set ignition control range to 5)
once i plug usb cable to hondata, edit idle settings is unavailable and it reads 0 (i guess that's normal)
after upload, i see on my laptop that the settings is 20,95. (that's why i think is upload problem)

maybe i should try older versions of kmanager or different laptops?

The settings can only be changed when a K-Pro version 4 is plugged in.

You can't, you will have to upgrade to the version 4 for this feature.

ok, thanks that's explains a lot.

but how is it possible, that i was able to do this with hondata v2?
after over a dozen of times trying, messing with settings i had random successes.

and is it normal to jump like that like showed in datalog?

It's not a feature you have control of without having a version 4.
