I didn't read ALL 25 pages, but ...Is there a "Wiring Harness Adapter" available with a plug on BOTH ends, to just plug into the original wiring on one end , & the other end plugs into the 7730 without any "repinning" or "cutting" required ? ( Like the adapters they make to "change out stereos") ? Thanks

YES
"Mulletproofmonk" was making them, you might try contacting him.
I bought one from him and even though the wires were a bit shorter than I would have made them myself, it worked fine. ------------------

Well it took me 2 days to read most of this thread. Been trying to get the parts together for this swap and got an ECM from a 92 Corsica 3.1. The service # is 01227730, 863411 M111475137, 16173411. Don't know if this was an auto or stick, engine and tranny were both gone. Since it still needs reprogrammed guess it doesn't matter, right ? Also both 32 pin plugs have C&D and 24 pin has A&B. So the green/yellow plug should be E&F, E=C, F=D. Is this right ? Also Ryan since you last tuned my car, can you transfer that info to the new chip ? I am wanting to use the DIS and knock sensor functions also. Any recommendations on a good heated O2 sensor, You said the present one was slow or was that because of the 3" exhaust. ------------------

if the o2 sensor is further away from the manifold than normal, it will take longer to heat up and give a accurate reading. its possible for a non-heated o2 sensor to be so far away it never gets warm enough. even cars with the o2 sensor directly in the manifold can benefit from a heated o2 sensor though. it shouldnt have anything to do with the size of the exhaust pipe itself
I like denso o2 sensors

I finished doing the swap today, and she fired right up. Wo-hoo!
Did a short test drive, everything felt normal or better, so TC so far.
The repinning took only 2 hours (double checking everything), but I did the extra wires with Metripack (inside) and Weatherpack (outside) connectors and made sure everything looks stock (important over here).
I did a few things slightly differently:
I made an EGR harness that runs from the digital EGR, inside the plastic sleeve on the valve cover ending in a four pin Weatherpack connector which fits the stock Fiero EGR connector. This already had 12v and signals for two EGR coils, I removed the ground terminal and inserted a third wire for the third solenoid. This wire goes to the fan switch terminal via a one pin weather pack. This way the engine compartment looks completely stock.
The high side pressure switch wire needs to be cut, and I cut the fan switch wire next to the ECM, feeding one end to the EGR third coil driver, the other end to the fan relay driver.
I also swapped out the Fiero fuel rail for a F-body fuel rail, keeping the Fieo injectors. The new fuel rail doesn't have the hole for the CSV line. I also plugged the CSV hole with a plug from TPIParts.[This message has been edited by fieroluke (edited 05-01-2012).]

I've driven the car for 40 miles today, the engine feels alive! It's hard to explain, but I had a stalling issue when accelerating from a stop - gone. This upgrade is great, I'm very happy with it. I highly recommend it...
Thanks Darth - I always suspected the dark side to be more powerful ;-)

Now that the season is starting again, I have to work out a few wrinkles:
1.) Every so often, I get the SES light, usually when decelerating. Of course there is never a Scantool at hand when that happens, but I suspect it's a Code 32. I'll check if I have a restricted gasket, and I also got a replacement EGR valve.
2.) Highway only mileage at around 80-100 mph is a lot better than before the upgrade (may have to do with 95/98 octane gas here and the knock sensor), but my regular daily driving cycle has about 15% worse mileage than before. I didn't feel the DFCO kick in, is that disabled in the PROM?
3.) Sometimes I get a hard start, and exhaust smells like gas, so it's running too rich. Other times it's fine though...
