Sounds to me like the VSS and reluctor you installed into your trans is putting out about 24,000 PPM which is what the later manual transmission VSS/reluctors produced. The ECM chip would need to be reprogrammed to fix this. The only other way to work around this problem besides getting the chip reprogrammed would be to purchase an aftermarket speed sensor signal adjustment box like the SGI-5 from Dakota Digital. But it would probably be cheaper to have your chip reprogrammed.

You will need to have adobe reader installed on your PC. Then when you click on one of the 7730 swap links on my webpage, it should open a new window or prompt you to download a .pdf file. If you have lots of anti-virus software or similar protection on your computer it may be blocking these links -- but still something should happen when you click on these links that prompts you that a file is trying to be downloaded or something. (do you see the notification bar appear at the top of your browser when you click one of these links?)

Was the chip reprogrammed for a manual transmission or is it programmed for an auto? This problem could also be caused by a vacuum leak, incorrect throttle stop screw setting, or IAC problem.

What does the "digital EVAP purge valve" for the digital cruise control look like? Can someone post a picture of the parts I would need for this?
I'll also try to see if there are some 7730 ECM at the yard if anyone needs one PM me.

Here's a link to a picture of a EVAP purge solenoid used on the 3800SC engines (also known as Canister Purge Solenoid)

Okay, I think I overlooked getting some of those from the junkyard...

Hi all,
After a long preparation and following this thread closely, I have finally got this ECM swap done.
We usually do all of the work on our Fieros on our own, but this time around the circumstances led me to Darth's shop and getting the job done by the pro himself.
I have no affiliation to Ryan, I emailed him a few times with questions and liked the responses, then we met at the 25th, and that closed the deal for me. Since I was on my long way west, he agreed to do the project ASAP and I was @ his shop 2 days later.
This is not a technical writeup but picture log serving as a description of the general process and the fine work Darth has done on my Fiero. I thank Ryan for his patience, as I was hovering over his shoulder with my camera (as I do in our own projects  )
I hope this would clarify the 7730 swap and help others take on this mod.
~~ 7730 ECM Swap ~~ Pictorial description ~~
At the shop
All the parts I've brought with me, most removed from a Beretta GT
Darth Fiero 
Wiring harness I got out of the Beretta. Used for the ECM connectors etc.
Center console removed and a hole drilled through the right connector to run the extra wires
(The mess of wires on the left is for my Carputer, and not relevant to this project)
Wires into the cabin
Wires on engine side
This is the Digital EGR adapter plate made by Gwain, a.k.a Marc
EGR bolts properly torqued
EGR wiring
Wires running close to the fire wall
New knock sensor and wires
Completing the cabin side wiring, soldering and heat shrink
Installation of the Fiero 88 4cyl ECM tray to match the 7730 ECM
Final wires tapping
ECM installed
EGR control solenoid deleted
Cold start injector disconnected, Fan switch disconnected, Redundant vacuum lines cleared and plugged.
New EVAP control unit installed and wired in place
"Set timing connector" - installed on the distributor wiring to allow adjustment on base timing
(The timing plug is just below the spark plug wires. The extra plugs you see are for the MSD box.)
All ready for the tunning
And more tunning...We did several test drives and further tunning to bring the setup to it's best performance and drive ability.
Final product
Out and ready for her maiden voyage 2859 km home...
Since we don’t have exact “numbers” to go by, all my comments below are based of my “feeling” and knowing the car.
After this road trip I have noted the following:
- Startup - The car starts up great and rests at the set idle of 850 RPM (sounds nice)
- Gas Mileage - I would keep monitoring it, as I did 98% highway driving I did not notice a measurable improvement yet.
- Response and power - The engine feels solid and "alive" - no other ways to describe it.
- Pinging - My Fiero had pinging issues that we were not able to solve for a long time, this problem prevented me from properly enjoying the car. Needless to say...Bye bye pinging 
Now with the knock sensor the engine can be pushed and pulled any way I want to, with no fear of internal detonation damage.
(I know the real problem that caused the pinging might still exist, but since we tried EVERYTHING...I'm just glad it's gone)
Don't let my subtle ways mislead you, I am extremely satisfied with this mod and positive that with time and new tunning possibilities embedded in this "newer" generation ECM my overall satisfaction and joy of driving will increase.
Given the time and place I would have done this project myself with the help of my Fiero friends. However, I don't think I would have been able to get this project properly done and running within the time restraint and using "trial and error" method.
I would like to objectively and openly recommend Ryan's services in performing this and other performance upgrades. I found him a true Fiero expert and a great guy to deal with. I have paid his asking rate for this job and he has exceeded my expectations in the level of craftsmanship and end result.
I decided to post this info in his original thread so to keep good information in one place.
I would keep you posted as I gain more experience driving with this improved engine management system. To all of you that are considering this ECM swap. Go ahead  ------------------

TTS Datamaster, TunerPro RT, and EFI Live V4 (OBD-1) will all log data from the 7730 running the $58 (Syclone/Typhoon) .bin file I made for you. I think what you buy from moates.net is just the cable, then the scanning/logging software must be downloaded/purchased seperately. The Datamaster software has a 20-use free trial and can be download from the net. The TunerPro RT software is actually a tuning suite but has a scanner plug-in; and is probably going to be your least expensive choice out of these three. EFI Live OBD1 has to be purchased to get the full use out of it.
