You can leave this menu (F10 Zuruck/ Go Back) to go to VANOS Screen, and newly-selected idle speed is maintained. If you Enter 1020 and click OK (so you can Test VANOS as described below), that will remain the idle speed maintained UNTIL you return to this screen and enter a different speed, OR use the F1 thru F4 buttons to change speed.

See the 2nd attached INPA Screen for what that looks like. When you select the Auswahl/ Selection Button, a Dialog box is opened into which you can type ANY value between 0 and 2,000. Enter Specific Desired RPM: DME > F9 > F5 > F6 Auswahl 'Selection': OR, you can select F6 Auswahl (Selection) as described below.ī. This screen as opened allows you to simply OBSERVE or view current setpoint & Actual Idle Speed (Live Data), BUT if you see the Submenu choices you can click on in the INPA 'Taskbar', you see you can add or subtract in increments of 10 or 100 RPM by simply clicking the buttons. When you press/click that Menu Selection sequence you should see the First Screen attached Below, which simply shows the current ACTUAL RPM, and the Setpoint or Requested speed: 664 & 660 RPM respectively in my case. Open DME > F9 System Diagnosis > F5 Increase Idle Speed: With INPA, it's so simple, even I can do it.Ī.

Also, you may want to reset your idle speed (Setpoint or Target Speed) if you find your warm engine idle too High/too Low. Some Functions or Activations, such as VANOS Activation described below, require a certain Idle Speed. Change Idle Speed Setpoint: DME > F9 > F5 Idle Speed Adjustment: To connect with ANY module, you need to know the VARIANT to make proper selection from the Right-hand Listbox. Generally, N51 & N52 Engines use either MSV70 or MSV80 (2007 & Later) DME Variants N54 Engine uses mostly MSD80 DME Variant, and Later N55 Engine used MEVD17x Variant. Specific steps to save & attach INPA Screens are described in attached in the last paragraph ( INPA Tutorial Quickstart (Functional Jobs examples). TL DNR Types: LOOK at the attached INPA Screens FIRST before you dismiss. It is very powerful, but many/ Most ALL versions I have seen, are in German with LITTLE Translation to English, other than Menus.
