Make sure you have Alpha-n setup in the Control Algorithm on page 1, Injector control

Just a WAG, The 2 map sensors have to be same!! It sound like you have mismatch in sensors and the correction won't work right.
PS you only need the MS Map sensor unless you have blown engine ( turbo or blower).

I went in and use the VE generator and changed the Kpa to 60 at idle an now have the resolution in step of 5 KPa now.
And was able to get the engine to run much better at idle now.

my vacuum gauge shows 15" of vacuum not KPa. Its 63Kpa at idle! The engine has a large overlap which is causing this problem.

My engine only has 15 lbs on vacumn at idle, would it be best to change the map to a 1bar sensor so I can tune the VE table better.

Information can be found in MS2 Extra Ignition Hardware Manual for using VW cops. I'm using them
on my engine.
