RE: [alfa] L-jet conversion, CT Berlina



Yikes, why would you do that?

Seriously, the L-Jet is a lousy system.  If you're going to all that
trouble, do a MegaSquirt conversion instead.   You can modify the Spica
manifold to take electronic injectors.   You can get 19lb injectors really
cheap.   Use the type-3 injectors  from a late SBC.   You can buy fuel rail
form www.rossmachineracing.com for $12/ft.  You'll need about 2 feet.   The
MegaSquirt has a relay board that mounts under the hood to fuse and relay
everything.   You can bypass the TPS with a downloadable code modification.
You'll forgo the flood-clear mode.

Tach signal is taken directly from coil(-).   I converted to a Plex on my
L-Jet Spider removing the Bosch spark box.  Worked fine.

You'd need the following:

Spica manifold machining, probably about $100
MegaSquirt injection controller.  $140 parts.  You solder together.
2' fuel rail $24
19lb high-z injectors ~$50 or less
MS relay board $30
Wire  ~$30
Injector connectors $30
IAT (intake air temp sensor) $25
CLT (coolant temp sensor) $25 - not the same one as the gauge.

I'd bet the L-Jet conversion will cost you more than that.

While you're at it, use an inductive pickup distributor like a Plex or RML
and insert a GM HEI-7 module for programmable spark advance control too.

If you're interested, I can give you more information on converting.
