new member, first question

[JP Lorrain]

Hello,

This is my first post to this list, I have joined to find more
information on a specific project I'm doing right now.

I own a 1987 Merkur XR4Ti 5-spd.  It has the Ford 2.3 liter turbo
found also in T-Bird TurboCoupes and Mustang SVO's.  I have upgraded
the engine with an SVO Vane Air Meter and T-Bird intercooler and am
now searching for a 1986 SVO ECU to replace the stock Merkur box.  The
86 SVO ECU is optimal for my current engine setup and takes full
advantage of the IC and better breathing made possible by the larger
VAM.

My 87 Merkur XR ECU is engineering number is E5ZF-12A650-F1D.  The 86
SVO ECU is engineering number E5ZF-12A650-E1A (also E2A, E3A).  My
question is this:  What differences are there in the ECU's?  I know
that swapping them is simply a matter of plugging one in for the
other, same connectors, wires...  Is the only difference in the E-prom
chip itself?

I'm hoping that the difference is solely in the E-prom.  I have a
friend with a 86 SVO and can have access to his ECU.  I own an E-prom
burner and can copy the chip easily.  I figure I should be able to
retain the original ECU and simply change out the chip.

I need confirmation of this though.  This list seems highly technical
and I apologize for posing a rather mundane "I want a superchip" style
question.  After I get the information, I probably won't stay on the
list.  But I invite anybody with Merkur or 2.3 Turbo specific
information to drop by the International Merkur Owners Network talk
list and drop some knowledge on us.

Thank you very much for your time, and thank you in advance for your
answers.

Bye, JP
