First of all, I'd like to thank Wesmaster for patiently answering my PMs. I thought I'd give him a break and post my questions publically to ease his pain and perhaps start a brainstorming session with this topic since the E-Manage is rarely discussed on this board.
The following is what I posted on Yahoo's E-manage Group:
Hi fellas,
Thought I'd try posting here for advice. Any clues are appreciated.
I just completed the wiring phase on my 2001 S2000. No forced
induction here, staying NA. What is wired is the standard main
harness along with the optional ignition and injector harnesses.
All the harnesses are spliced into an "intermediate" VAFC harness
(so as not to cut into the original harness).
I installed the loom and turned on the ignition and the two LEDs on
the E-Manage unit are lit, solid orange on the interaction LED and a
quick flashing green on the active LED. I push the ignition button
and it cranks over but will not fire up.
Before you folks say double-check your jumpers, rotary settings, I
have. Probably an insane number of times.
4-8-C
JP1 - 1-2 (Left two of three)
JP2 - 1-2 (Right two of three)
JP3 - 2-3 (Left two of three)
JP4 - 1-2 (Both two)
JP5 - Open (None)
JP6 - Open (None)
JP7 - Open (None)
I have quintuple-checked the harness for continuity and I'm
confident the harness is wired up correctly.
Everything on the car acts OK when I turn on the ignition (guages
light up etc - No CEL), just won't catch when I crank it over. I'll
remove the E-Manage and harness and return it to stock and it fires
right up so I didn't blow a fuse.
So to my questions:
What does a fast flashing green on the active LED tell me? The
manual only refers to a flashing RED LED for troubleshooting.
Do ya'll think that since I installed the optional ignition and
injector looms, I have to first get into the E-Manage utilizing the
support tools and do something in there first?
I haven't done this yet, I'm having difficulties getting the serial
connection to work through the cable that I just recieved from
Robyn. Seems as though he creates the cable with a female end on
the serial side and my laptop has a female connector as my serial
port. A gender-bender will resolve this, just have to go source one.
I'm stuck for now. Any help is greatly appreciated!

Wes,
I checked the "4-8-C" setting again and it is correct - No blown fuses.
For the benefit of others, if you turn the key on with the ignition harness installed and the incorrect dial settings you can blow the coil pack fuse under the dash. Some settings we tried did not blow the fuse while others did. So, if anyone does have a problem with the car starting after having the incorrect dials set, this is something to check.
The good thing is that since you used a V-AFC harness you can unplug the eManage and see if the car starts. At least that would isolate the problem. Try that.
BTW, the Active LED flashing means that the eManage is "correcting", or making changes to the voltage sent in from the wires. Mine blinks all the time too, for no good reason.
Thanks Wes. Yeah, I did what you stated above and removed the harness and E-Manage completly and went back to stock...fired right up.
Just wanted to keep this post filled with any information from the E-Manage group for future refence:

Subject: Re: [emanage] S2000 - Flashing Green Light on "Active" LED - Cranks but won't start.
well...I did a test...
After I disable the "Ignition Timing Adjustment Map" in the
"Parameter Setting" dialog, the engine can still fire up.
seems that even you did not enable the ignition control,
the main unit still works hard repeating the ingition signals.
Did you get the right corresponding sequence of the 4 ignition
wire? if you mess up the sequence, the engine won't fire up smoothly.
The flash green light of the active LED means the Air Flow Adjust VOL
control, at the right side of the active LED, has been triggered.
To void the green light , try to turn the the arrows to point to
0 as accurate as possible. If you have the support tool, you can
see the exact numbering read by the emanage.
Get a "Gender Convertor" of the DB9 will solve your connector problem.
by the way, can you post your HONDA ECU's number? it starts like 37820-.....
We had a problem with an S2000 here that my mechanic and I were tuning. My mechanic had soldered the harness for the customer. After hours and hours of having trouble getting the eManage to correctly add fuel we gave up. When the mechanic removed the harness to put it back to stock he found the problem. He had heated the V-AFC wires up too much when soldering and he had created a short inside the connector. So, just double check everything on the wiring harness. I don't know what else it could be.
You should have originally had a 4 ignition wires going from the long V-AFC connector to connector C on the V-AFC's ECU-side. Those should have been cut. When tapping them the IN that goes to the eManage would come from the ECU-side, since you're intercepting the signal that the ECU is sending out to the coil packs. Then the out would go to the V-AFC long harness, and eventually that modified signal goes out to the coil packs. You have it backwards huh?
