E-manage Ultimate Hardware
Versions Updated August 8th 2007
You may have heard about the e-manage ultimate ignition chip
coming loose on some units, after reading many mailing lists and forums, I
started this page to clear some misinformation on this issue, First I will
start with the e-manage ultimate versions that hit the USA market,
From my experience selling the e-manage ultimate, I came to the
understanding that greddy made 5 versions of the e-manage ultimate hardware to
date, they are identified by the alphabetical letter printed on the board near
the 14-pin male white male harness, example,
Version A - I have not seen this version, it could have
been a pre production version.
Version B - This is the first version to hit the USA
market in July of 2005, I think it started at serial #1000 to #2999. This version is easily identified by the the white
cloth that covers the chips near the 'Active' led light, they were covered
because they came too close to the housing rail, I haven't seen any of these
units knock out the ignition chip, it could have happened to some users, but I
haven't see it personally happen on this serial range. there are many pictures
of this board Here.
Version C - I think it came out late 2005/early 2006,
this version had a hardware change in the same area where the white cloth use to
be, they moved the chips further back so they don't make contact with the
housing anymore, I believe this version had serial #2000 to #4999, in
this version I have seen the the cases of the ignition chip being knocked off,
I want to point out that if the engine suddenly doesn't want to start (when the ignition harness is
used), most likely the ignition chip got
knocked out while the e-manage ultimate board was being installed by the user into its
housing,
Neglect in inserting the board into its housing carefully will cause the chip to
be knocked out of its board,
This chip is a buffer input stage from the cars ignition...its marked "TD508AK
62503F".
According to the data sheet of this chip, "7ch SINGLE DRIVER (COMMON EMITTER)"
Repaired in this picture, you can solider it in carefully by yourself (will lose warranty), or
GReddy will if you still have
the chip, Contact the GReddy dealer that you bought your unit from and see what
they can do for you...
Version D - first seen in
June 2006, this version I believe started at serial #5000,
it got new hardware changes, actually it have so many changes that I can't
count them all, there are many parts that got moved around, and there are some
new parts added, the most noticeable change is the new locations of the jumpers,
greddy manual includes a sheet that shows the new locations, see this picture,
There is also noticeable clear and shiny substance under & over
the chip that usually gets knocked off, I think its a type of glue to give the
chip more strength to stay in place.

side by side,
Version E - first seen in
January 2007, didn't make it to the USA market till July/August 2007, this version I believe
started at serial #7000, and as far as #11000++.
There are several positive improvement that I noticed, the
ignition chip is finally relocated to a new safe position, see this picture,
They added one new pin, older versions had 20 pins, total is 21
pins in version E
