• DIY Autotune

  • My favorite source for MS kits and supplies.  Excellent customer service and very fast shipping.

• RS Autosport

• Glenn's Garage

  • All the usual MS parts/kits.  Also has several nice add-on boards for things like extra ignition drivers and 3-wire idle air valve controller.

• jbperf.com

  • Not a full MS supplier but has a few interesting boards.  This is the person who developed the current version of the JimStim.  He also has a nice dual VR sensor conditioner board and a signal breakout board.

  • Don't want to go through junkyards looking for EDIS parts?  Boost engineering sells used EDIS components.

Megasquirt parts for the M10 engine

• 02Again

  • This place has some really nice parts for adapting the EFI intake manifold from the E30 318i to Megasquirt.  This manifold is a direct bolt-on to the M10 engine and is the easiest way to convert an M10 engine to Megasquirt.

Other Megasquirted M10 projects

• Tim's Megasquirted 1973 2002

  • A very well done conversion that uses the old style M10 intake manifold.  He also added a wasted spark coil on plug ignition system.

• Ken Danielson's web site

  • Ken has an extensive site that documents a wide variety of projects he has done on his E21.
