[Gmecm] FI on AMC motor

Thu May 31 17:58:05 UTC 2007

Hello Denny,

I've got an '84 Cherokee XJ, which came from the factory with a Chevy 2.8l.  When I switched up to a 3.4l at 400,000kms, I used the worn out carb for 2 years then went for FI.  I initially planned to put in TBI, thinking it would be easier for a beginner, but TBI is too tall for the Cherokee hood to close.  Complete MPFI motor and harness from a Fiero came along at the right time/right price, with no ECM or EGR.  A repinned connector later and it's running with a '7730.

This conversion has been so successful, I'm now casually looking for a complete 454 TBI setup to put on a Buick 455.

Checkout customefis.com for info on injecting an SJ.  I can't find it on his sight now, but he used to have photos etc. using TBI.

Duncan

Know what the connectors on that VSS are?  Any part numbers on them,  or what 
PN could be referenced from a place like GMPartsDirect.com?

I found a dual output VSS  that came on 1993 Caprice cop cars is still
available from several local  auto parts stores. NAPA # VSS231 or CSK #DR1044
is what I used. It was  around $60.

It has the VSS output for the ECM and a mechanical  speedometer cable drive
that was used for a mechanically driven radar gun.  It worked great when I
put a 4L60 & LT1 into my 67 Chevelle with the  original mechanical
speedometer.

You will just need a conversion  speedometer cable made for your current
setup if the AMC transmission  connection is different and later one made for
the MG swap to use the  original MG speedometer.

Hope this  helps,
Mike

I just used the factory LT1 wire harness connector. It looks the same as all
the other 700R4 & 4L60 VSS plugs that I have seen though so you could find
it on many vehicles at the wrecking yard. I have found that most Astro &
Safari vans are a good source for 4L60 and 4L60E parts.

The mechanical speedometer connector was the standard old GM part, nothing
fancy. Pretty much any 60's to mid 80's GM car would be a good donor.

Hope this helps,
Mike

You mean to tell me you put fuel injection on an AMC motor? I have been 
looking for away to do that for my offroad truck.
Would like to find out how you accomplished that!

Denny
