Howdy, all!

I just joined this list, after reading a post from John Gwynne on one of the
ngs.

I dont have a lot of EFI experience, just enough to get me in trouble    :)
but I'm in the middle of a TPI swap into a 69 Vette.  The engine is an 86
iron head, with a 7730 computer, which will be wired like and initially use
the PROM for a 91 Firebird 350 VIN 8 engine.  I have all the plumbing in
place, just have to mount the ECM and harness and see what happens.  Been
too busy working on the house, and playing with my new used lathe,
though...and its kind of cool out in the shop.  In other words, I been
procrastinatin'.

Does anyone want to lay odds on how far off the PROM will be, if an
aftermarket performance PROM would be better, or whatever?  The car is a 4
speed manual, and the PROM is for an overdrive automatic.  I am installing a
speed sensor, and I already made a VATs signal generator.  What other
surprises will I have?

Also, I dont have an EGR solenoid figured out all the way.  The engine was
kind of what was lefover after a guy put a used 90 Vette motor into his 86
Vette, the harness had just the engine end connectors, and not all of them.
For the computer end of the harness, I got a 93 Sunbird V-6 harness from a
junkyard for $50 (cut off somewhere in the middle), and am splicing on all
the 90 Vette engine end connectors, using the 91 Firebird shop manual as a
go-by.  The EGR solenoid was missing from the engine-but, as I realize all
the EGR valves and solenoids and PROMS are calibrated to work together,
where should I start to get a workable system, at the dealer buying 91
Firebird parts?

Any comments, ideas, flames welcome    :)

Jim
