When do you think this will be out of BETA?

In the Megasquirt world, things typically go like this.

A New Idea = Some person has an idea that he posts on the site.  If the idea gets traction, the programmers may start to like the idea and start tossing ideas around how to type it up.  Three main guys do most of the programming.  A different guy does the MLV programming.  The is no company as such with an office.

Alpha = We think we have an idea that should work but we need a couple of people to try it on a motor and see what happens.  It appears to work on a scope and the bench as expected. 

Beta = We think it is working but we need a bunch of people to try it and see if it is working as they expect this sort of thing to work.  The programmers reserve the right to change the way it looks in the GUI a lot as people ask questions.

Release/Stable code = We know of no issues with the feature set.

I have seen things get thru this process in about a week.  Other things can take a year or never do make it to release.

With the Harley stuff.  One guy is making all sorts of HP, but he has a cam sensor making things easier.  The other guy is working thru the issues that come up on this sort of thing. 

Anybody can purchase raw boards, build a case and harness and sell them for a profit for any specific market.  The business model is very Linux like.  Lots of guys with lots of ideas and things get better very fast.

Hmm. You got me thinking. I have an older S&S SSW 124 Evo engine out in the shed. It has a standard Evo style cam sensor but it also has a hole in the left side of the case for a crank position sensor.

What does the Evo cam sensor and the crank sensor in a typical Evo style S&S 124" do for MegaSquirt?  Might have to put together a mutt rigid bike just to play around with this stuff.

It makes it far easier for the programmers to figure out where in the 720 degrees of crank rotation the motor is at any given time.

We have a Sporty up and running on a Microsquirt.  The switchover from wasted spark to full sequential fuel and ignition appears to be working.  Next step is getting the narrow band - dual channel - autotune working.  Once we get that working, we can dial in the fuel balance stuff on low power and then move on to the wideband single channel - boosted tuning.

This is going to be fun.  It is so much fun working with really talented programmers and everyone involved is on a mission.  :)

Way cool stuff.

Here are some plots that highlight the issues of the fueling on a Harley Sportster.  They have a difference in fueling requirements front to rear.

My  bet is it is going to take dual widebands to truly dial in a turbo/blown Harley.  They will have to be relocated from upstream of the turbo for low speed balance to downstream for high MAP loads.

These graphs look to be front cyl only?

Folks have been trying to balance fuel requirements on carbed HDs since individual cylinder O2 sampling began...circa 1976.

Another reason sequential port EFI is more desirable than a carb for these engines.

The learning curve is fairly steep compared to what the Harley world is used to but you will not believe how powerful a Squirt is.

Wait till you get a chance to work with what's coming down the pipe. Beta testing has been very promising for getting timing effectively handled as well as some smarter tuning strategies.
I love working with the Delphi system for its smarts and knowledge base out there.
Way cool stuff for sure!!!

I have a Sporty.  Almost none of the new stuff ever applies.  Sportys even have some fundamental busts in the code that has never been addressed.  Most of the tuning logic we are forced to do is driven around work-arounds.

The Squirt direction may allow the mid 2000s and later EFI bike builders a true option.  Big power (like 2 hp/CI) is just not a problem provided the motor can be built to take the loads

I have no idea if the fuel pumps will keep up but.....  The fuel tank most likely will starve once we get the acceleration rates up to something reasonable.

Oh, I thought you had experience with big twins as well.
Then, hopefully you will get a chance to work with a big twin to see the upcoming way cool stuff!

Any progress made with mega squirt system. Interested in using for boost application. Ran across this tread searching for mega squirt info. Thanks
