The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.
A forum for discussing topics of particular interest to those running MegaSquirt in Australia and New Zealand, including parts sources, group buys, etc.

I've been stalking you Kendall and found the above post here
Can I run my thing on LPG and retain the MS for spark AND fuel?
I thought LPG injection was out of the question, but a conventional LPG setup controlling fuelling and MS controlled ingition would be doable. Am I wrong in that assumption???
Damo.

I suppose there would be some kind of dual table setup you could run... I have not seen an LPG injection setup 'in the metal' but I reckon they would be pretty good, especially with a dirty big snail bolted to the side. I think the power gains come with reduced intake temps and such - has to be better than the 'carby' lpg crap that us mere mortals use - backfires, lean spots, no guts off idle, etc. PLUS gas converters that fail regularly because of the oil in the lpg baking itself onto all the moving parts - just lucky the price of gas makes the repairs affordable. LPG injection - mmm, good.
1984 Ford Falcon 250ci inline 6 MS'd of course!
Now improved the way Ford should have built it with a 4speed automatic.
Also with 3.45 LSD for added goodness.

Do you think the factory LPG Falcons be able to donate bits that we could use? I have NFI what their setup is, and haven't seen one.

We are thinking along the same lines ;-) oh, and LPG is realtively cheap too!

The next project vehicle is starting to come together in my head, and LPG injection would be perfect for it. Time to start researching I think!

Yeah, I have NFI about LPG. Liquid injection sounds like too much trouble, and expensive. And as far as I know the only other alternative is the old school stuff. And that just isn't any fun coz you cant control it with MS
Thanks for the coffee BTW! Was good to catch up.

I have a feeling that the falcon LPG, along with alot of other systems, use the carby mixer style setup, but rather than a mechanically ooperated valve to meter the mixture, they use a pulsewidth controlled valve so the fuel is still controlled by the ECU.
but this is only from a fading memory as I never had alot to do with them as they were just new when I wasw still an apprentice and I moved on not long after.
EDIT: one of the guys on the ausrotary forums brings up a thread about LPG injection occasionally, last I heard the LPG injectors were still prohibitively expensive. and unreliable.
I forgot about the GRA stuff... They make a dual fuel variant too - but the stuff is expensive - although it is government subsidised. Should be OK - have a look at their website - there are a few turbo boxes on there from what I remember.

Just thought you guys might be interested in something I found, LPG injectors.
There are 2 main types of LPG injection, liquid LPG injection which deals with LPG at very high pressures, and LPG vapour injection. The latter is pretty similar to how old school LPG systems work except instead of a gas carby or throttle body they use an injector to supply the vapourised LPG. The injectors don't look anything to exotic, they look like they use a standard Bosch connector and i'm sure I read somewhere they are about 4 ohm. I can't se any reason why MS wouldn't be able to run these things. Injector opening time may be a little different than normal fuel but I believe the LPG vapour injectors open up much wider than a normal fuel injector, so it probably wouldn't be too much different.

Romano Autogas is the Italian company that makes those injectors, I haven't found anyone else that makes them yet. Their web site is http://www.romanoautogas.it/. And they have an Australian distributor in Melbourne, http://www.amrgas.com/. I have also seen the Romano injectors on eBay(!) for about $50 a piece. I haven't been able to find specs (flow rate etc) on them yet though. eBay store http://stores.ebay.com.au/Partsrange
