-S2000
-Serial no. 10529
-hardware version 3, software version 4.1.4.0
-AP1 basemap with added fuel for F22c
-After uploading map to vehicle and running vehicle until operating temperature, when I run the A/C the car shuts off at idle.Vehicle runs well without a/c on. This issue started just after I uploaded the newest manager.
Calibration: Datalog:

I have discovered that if I move the idle valve adjuster to the highest setting, the car won't die when the A/C is on; however, when the A/C is off I now have too-much rev-hang. There are a couple of other things that did not translate well from the old version of k-manager to this current version. I hope adjustments for the s2000 users become available.

I'm trying to get one of our dealer to set this on his car.

As for rev hang, that is only present on car with drive by wire throttles.

There really should be no difference in the way the car runs from one version of K-manager to the other.

Try going to the online menu and erasing the ECU, close the program, reopen it and then upload the calibration again.

This seems to be the same problem with all PRA ECUs. The data from datalog shows the same thing. Some IGN correction kicks in @ idle adding +20 advance which at idle is way too much. Alternator not charging, battery voltage goes down, engine stops. Havent found source of this IGN advance to set it lower. See theese posts: viewtopic.php?f=12&t=18384 , viewtopic.php?f=12&t=18801

Thank you for responding. I guess when i say rev-hang, it is present because I have the idle valve at it highest setting and while at idle, if I tap the gas, instead of returning to idle like it use to it hangs at 1500rpm then down to 1200rpm and finally returning to what I have set. I am thinking the issue i with the way ignition control idle is set up. On my application, I am usable to use it and I'm working if kmanager is still using those values.

Any update?

We're looking at it, and expect to fix the problem shortly.

But revs fo hang sometimes around 1500 until I drive less than 3mph then it settles down to my set 1000rpm idle

Do you have the k-manager v4?

Fixed in V4.1.5

Great thank you so much. I didn't see a it in the threads, sorry.

So for those of us that had the problem and corrected it, we should be able to return the idle slider back to where it started post software update?

Yes it should work as it used to now.
