MS2-Extra NGC - Next Gen Neon Manual
36-2+2

Only for use with the MS2-Extra code (HC9S12C64 based microprocessor - MS2 Daughter Board)

NOTE: Please ensure you have one of these daughter boards inside your ECU before continuing. If you have a black microprocessor, then you have an MS1 and these manuals are NOT for MS1 see here for MS1-Extra Manuals
Warning for E-Bay buyers!!
Please see the Official Suppliers list before buying through E-Bay.
This is there for your protection.

Please Note:

All of these instructions / diagrams are to be used at your own risk, like most things there is more than one way to do the same thing, what we have tried to do is to offer a method that we have tested or that others have tested for us. No warranty expressed or implied.

Use at your own risk.
If you do have any suggestions or settings that work please let me know Philip.Ringwood(at)ntlworld.com

Setting the Software

     

Ensure the settings are as above, the Dwell settings are for use with the HEI4 modules.

If using VB921's for direct control over the coils then set Spark Output to Going High (Inverted) and set dwell to Standard and 3.2mS as Maximum. Also set 5.0mS as Cranking Dwell.

Ensure number of cylinders is set to "4"
