[Diy_efi] dis 90 cutlass v6 3.1

[Lee M. Lemoine]

Hey there Larry,

I'm pretty familiar with the 3.1 also, have a Mclaren 3.1 in my cavalier
which has a custom ECM attached at the moment.  As was brought up by Tom,
the hardest part of making the system work is getting accurate timing and
triggering.  Maybe if we had a bit more information on this straight six, we
could help you a little more.  Some of the older GM slant sixes may be
easily retrofittable with some of the early V6 distributor parts.  If its
DOHC or whatever, there are other solutions...  What kind of straight six is
this?  What type of application (ie: street car, boat, etc?)

The 60 deg v6 uses a notch system like tom had mentioned.   (here's a pic:
http://www.jbodyperformance.com/new/images/jbp_frgd_84mm_crnk1.jpg  )  the
center portion of the crank has a wheel in it with notches cut. i have the
exact specs, but i doubt you'll be able to recreate that on your other
engine.  As mentioned before, the older 60 deg v6 and some of the straight
six stuff out of jeeps has hall effect sensors, which may be able to be used
in this application.

Give us some light, and we'll help you out the best we can.

Cheers!
