BMW E36 autocross MS3Pro PNP

It is a rare thing to find a car that does EVERYTHING well!  Dodging cones at your local autocross, clipping the perfect apex on a road course, or obliterating tires while drifting.  The BMW E36 is a testament to automotive ingenuity, offering the perfect blend of balance, driver engagement, and timeless appeal. Its 50/50 weight distribution and intuitive driving experience remain unrivaled, cementing its place in the hearts of enthusiasts. Now with the power of the MS3Pro PNP ECU, the E36 is granted a new lease on life, combining its traditional strengths with modern tuning capabilities. While it is well understood that the BMW E36 chassis is one of the most capable in the world, there is still room for improvement. Enter the BMW E36 Plug and Play line of standalone ECUs.

Why Choose the MS3Pro PNP ECU?

Unrivaled tuning potential and incredibly simple installation.  Never before has it been easier to take full advantage of modern standalone ECU capabilities. Are you adding a turbocharger or a supercharger?  No problem.  Boost control, rally-style anti-lag, and an internal 4-bar map sensor give you total control.  Building a high-revving naturally aspirated screamer? Go for it, taking advantage of fully customizable 16×16 fuel and ignition maps, VANOS control, and fully sequential injector control with individual trim tables. And, if that isn’t enough, there is full CAN BUS capability opening up a world of expansion. Race style dashes or displays, data loggers, and I/O expanding devices are now all on the table. These are just a few of the built-in features of the powerful MSPNP Pro! See the full feature set HERE.

Can I Install the MSPNP Myself?

With just a few hand tools and about an hour, you can bring that classic bimmer into the modern tuning age. Not only does the MSPNP install right in place of the factory DME, but pre-loaded base maps make startup a breeze, getting you up and tuning in record time.

  • Remove the factory ECU and Plug in the MS3Pro. Easy PNP installation plugs right into the factory harness!
  • Route vacuum line from engine’s intake manifold to built-in MAP sensor port on the MS3Pro ECU
  • Download the INCLUDED registered version of TunerStudio and take advantage of customizable dash layouts.
  • Fire it up and verify ignition timing with a timing light. That’s it! You’re up and running with one of the most advanced standalone engine management solutions on the market!
  • Tune to your heart’s content. REV limiting, boost control, traction control, idle control, table switching, wideband o2 control, and more!

Which E36 Models are Covered?
