I reinstalled KManager and the idle settings are still an issue. I even tried loading a basemap but I still have the same problem.

Okay, I'll reinstall KManager and give it a try.

In regards to the bug that doesn't let you set the Kpro to open loop, you said it's fixed, in which version? Soon to be released or the latest 4.1.1?

I attached a screenshot of the blanked settings. When I try to unplug, change, save and them upload to get around the bug, I'm not certain that it is working properly. Please let me know if this will be resolved soon, or I'll just revert to an older KManager version for now.

I made those changes you suggested and I think the issue is gone.

I added some more restriction to the IACV to bring the MAP reading to be closer to a non ITB car. I think that's probably what solved the issue. Thanks for the insight on how the overrun works. On that note, when you're on Alpha N ...

Every time I click "Disabled (Open Loop)" for close looped operation and try to save the KAL, it reverts back to "Narrowband (Secondary Oxygen Sensor) -PRA". Is this supposed to happen or is this a bug?

Hi HONDATA, do you think you can chime in on my issue? I have a lengthy chat with Spunkster on the phone but we didn't come up with very many ideas.

Also, would you be able to elaborate more on how the overrun settings work for Alpha N since it's a MAP value you enter?

I do have a vacuum manifold setup.

What do you suggest I try for the first overrun settings? Since my tune is alpha n, I need overrun to end as soon as I get on the throttle.

Can you elaborate a bit more about what is wrong with the vacuum readings?

I also tried physically adjusting the tps to be much closer to 0 (+0.4%) instead of -2.2%. I was still able to recreate the issue. Seems like every time I let it stay in overrun for too long, it can't exit out of it.

I'm using a stock harness with a couple things extended. I've been running this configuration for months before this problem arose. Both the map and tps signals read fine in the catalog when the fuel cut out.

I also just tried to revert to KManager 3.3.0 since I never encountered this issue prior to this month and updating to the newer KManager. I've been using my Kpro for at least 4 years and I've had my stroked F20 with ITB for the last two.

Based on the data in the logs, I'm 99% sure it's an issue ...

I tried making a speed density map instead of a Alpha N map. Both the calibration and log files are attached. Excuse the poor tune.

INJ went to 0ms at 1:43 of the log and stayed that way until 2:01 when I let it just stall out. During that period, I used the throttle multiple times but INJ stayed ...

I did some more testing and tried the following, but was still able to recreate the issue regardless:

I made a brand new one map and erased the ECU before uploading.
I changed the overrun cutoff settings to be higher than the Alpha N map value when throttle fully closed.
Tried to have fuel over ...

This sounds like a similar problem to what I have. Anyone know how I can resolve it?

S2000
Kmanager 4.1.1
F20C stroked to 2.4L
ITBS on Alpha N

Problem occurs at 4:32 and ends at 4:46. My INJ was 0.00ms for the entire time. You can see from the log that I tried to jab the throttle (both in and out of gear) to exit what I thought may have been an overrun condition, but it didn't work ...

I'm having the same issue. dimilo, did you resolve this problem?

My O2 sensor reads into the Kpro via the ELD but the lambda overlay doesn't work.
