weber-marelli ecu in an Alltrac

Hi Max,

woohooo.. a fellow Alltrac owner.  What model?
I have a 1990 ST185 Alltrac (well, they are called GT-Four's here in 
Australia).

Are you a member of the GT4 mailing list?
I would *strongly* recommend any Alltrac/GT-Four owner to become a member 
of this list, it has been by far the best resource for my GT-Four, and the 
guys (and girls) on the list are extremely helpful.
Check out:  http://www.onelist.com/group/gt4
You should be able to search and browse through the message archives there 
as well.  Its a pretty busy list, sometimes up to 100 posts a day.

There are numerous people on there running non-standard ECU's, although 
most of them are of the "normal" aftermarket variety (ie G-Force, Wolf3D, 
Motec, Autronic, etc).  Some of the guys are running around the 500hp mark 
in these cars which is pretty good for a 2.0 4-cyl Turbo.

I would be interested to know how you go with the Lancia ECU.. I have no 
experience with these at all so I can't really help you, although I am in 
the process of designing a "piggyback" system to the stock ECU to allow 
data-logging, FCD, AFC, and water injection control, turbo-timer, remapping 
sensors, etc.. etc..  Details of this project will be up on my website in 
the next couple of days.
I am very interested in this kind of stuff for these cars, but as I'm sure 
you know it is hard to find people who know much about them.

Good luck with the project, and I might talk to you on the GT4 list as 
well.

Cheers,
Adrian
