RE:Megasquirt FI

[406Special]

If you look at www.turbobricks.com you will see by any enquiry that Megasquirt is the FI of choice by all byut the latest Bosch LH2.4 units on hot Volvos. On my 2.5litre Penta version I am running LH2.4 plus Fred's chips.

Megasquirt is highly regarded, but no one seems to make it easy or simple to install. Takes a lot of effort from all the reading on the TB site.

I thought it might interest some of you, especially the very gifted or analy retentive as far as fuelling systems go and post the references I have kept on Megasquirt, in particular in case I was to use it on my Volvo turbo motor or keep the later (better) Bosch LH2.4 system. I decided the effort was hardly worth it and potentailly costly and exteremly time consuming. Better to use an after market proven chip upgrade to the Bosch unit.

http://www.msefi.com/index.php (this is their main site).

On www.turbobricks.com there are lots of articles and discussions about getting the best from MSEFI systems. But more interesting are the articles on getting MSEFI working with MOPAR engines (of all ages):

Have a read and consider your EFI options.

Clyde -

Thanks for the MOPAR references, which I'll pass to the Imperial Club
mailing list. Over time I've recall seeing one or two attempts to
put FI on the RB (big-block) engines, but not success stories. Seems
like it should be possible for around $1,000, but detailed "how-to"
instructions would be "priceless".

Bob,

No worries, the important thing is that the MSEFI success is over
there so much more accessible.

MS even suggest you can EFI a lawnmower engine! An RB block ought to
be not much more difficult - it's the mapping and programming that
takes the time, not the correct and appropriate sensors and injectors/
intake plenum, all off the shelf stuff. As you say the know how -
the IPR (intellectual property rights) stuff is priceless especially
if it can be readily and easily replicated!

As this thread is not Bristol specific it has been moved from "6cyl Bristol cars" to Forum: "Restoration and Repair - non specific".
---------------------------------------------

I don't see how you can capture any significant IP in the mapping and programming, because it will be different for every engine - there are too many variables.

Hi Clyde -

In the spirit of DIY, open source, etc. I suspect the RB Mopar EFI
mappings are probably done and available somewhere, by someone who
was happy for the peer recognition. Or it will happen that way.

I already have received a private email from an Imperial owner with a
354 hemi who expressed an interest in trying EFI on his
"restored/updated" '56! However, I really, really doubt we'll see
the same for the 6-cyl Bristol engine. Not mine, ever!
