I'm starting this thread to document the creation of "Mjölnir" a 2011 B5 with custom J&E piston and polished head with beehive valve springs (courtesy of Gas House Gorilla and Scooter Bob).

To date: "B5" has had its piston replaced with a cast AVL piston, its muffler replaced with a sportster unit, and its airbox replaced with an industrial microfiber filter from K&N ~ as well as a number of cosmetic changes .....

[gremlin]

The first milestone in this project occurred when ScooterBob cleaned up a spare cylinder and fit the full-custom piston for it.

Currently, Gas House Gorilla is finishing the conversion to beehive valve springs and the full polish of the head and ports.

I've been busy as well ......   

[gremlin]

The consensus being that the stock EFI won't be able to adapt to these changes in the combustion chamber ......  I've chosen to convert the bike over to MEGASQUIRT.  Specifically,  MS1 v2.2 hardware with modification for VR timing input, running MSEXTRA firmware.

Looking forward to seeing your progress Gremlin, the MEGASQUIRT sounds like a fun project that might help a lot of UCE owners

Very interesting project !

Look forward to see your ton-up B5 in very near future  .

In anyone is interested, here are a couple of very informative videos on MEGASQUIRT and its application in a car engine.

There are a few more good videos for its installation and tuning under the same youtube account.

  and I thought all the time you are the nice guy with the hat in your avatar. 

I see a bigger issue doing the TON with the luggage crate than with the age.

  Best part about that Megasquirt is that you can build it yourself... very cool Gremlin.  See if I can get to the Ooops ! store before they close 

[gashousegorilla]

   I got there and it's on the way......

Hey, wait a minute... does that say Bosch?

update:

The Microsquirt V2.2 board is coming along nicely in the planning stage.....

highlights >>

The board comes with 2 channels for injector control.  Since we only have one injector, the second channel will be repurposed for spark.

The kit comes with a board mounted MAP sensor, this will be omitted, the RE MAP sensor will be retained.

The kit includes opto-isolator circuitry for picking up timing from the primary of a coil, this will be omitted and redesigned for use with the RE pulser coil.

a handful of other parts from the kit will be surplussed <-- always have left over parts
