Automatic Shift Knob Swaps

Camaro

Here’s the Camaro knob in a Fiero.

Edit – Actually, this one is covered with leather. I’m not sure what it came from but it’s shaped exactly like the Camaro knob.

To remove the knob, take a small screwdriver or the tip of a knife blade, and pry the C-clip out from the front. It looks like a long wire staple, and goes straight in to the front of the knob, down towards the bottom. Then pull the knob straight up.

Corvette

Here’s a leather wrapped Corvette auto shifter (pictured without button). It looks like a nice size and shape.

84 Corvette dark-grey leather wrapped shifter and shortened the steel shaft by 1-inch. The knob matches the dark-grey of the interior. I got a new soft-leather shift boot from Dickman.

Custom

5 minutes and a hacksaw…and we have 100% improvement.

Take 1 1/2″ off of the shift rod. You could go probably another 1/2″ to 3/4″.

You could actually do this mod using the factory shift knob,or one like the Camaro knob…but it would take a little more work.
What you would have to do,after cutting off the shaft…is use a dremel or other cutting tool…to notch the rod back like it was originally.

Again…this wouldn’t be that hard…just a little more time consuming.
Even though this shift knob uses a ring held in place by set screws to hold it in place instead of the c-clip…I may go ahead and notch mine just in case I ever want to go back with a factory style or Camaro style knob.

Here’s the piece I cut off to show what you would have to duplicate.

ECM upgrade (1227730) for stock 2.8

ECM upgrade (1227730) for stock 2.8

Recently a friend of mine brought me his Fiero to have a swap done. He had a very high mileage stock 2.8 and 125-C and wanted me to swap in a lower mileage 2.8 and 440-T4 OD transmission. Not content with sticking with the stock 2.8 ECM, I convinced him to swap out ECMs during the swap as well. In short, it was an excellent choice!

The ECM that was used in this swap was the 1227730 unit which was used in many 1987-92 era GM cars. For this application, I elected to use the $88 code mask programming which was designed to be used in a 1990-92 Camaro/Firebird 3.1. The Camaro/Firebird 3.1 is very similar to the stock Fiero 2.8 including it’s use of a distributor and iron-heads. With that being said, there were some significant differences between the two systems…

The 7730 ECM running $88 code mask does NOT use or need the 7th injector (cold start).
The 7730 ECM controls the coolant fan relay directly.
The 7730 ECM will interface with stock Fiero 2.8 ECM wiring harness. (although some modifications will be needed)
The 7730 ECM uses a knock sensor.
The 7730 ECM interfaces directly with the speed sensor which means changes can be made in the programming to calibrate the speedo without having to change out the plastic gears on the VSS sensor itself.
The 7730 ECM running the $88 code mask will NOT work with the stock Fiero 2.8 EGR valve. It is designed to work with the digital EGR valve used in the early-mid 90′s era GM V6 cars. I went ahead and designed an adapter plate and had another Fiero friend make one up so we could use the digital EGR valve on the stock Fiero 2.8 y-pipe.

The biggest advantage to using the 7730 ECM in a Fiero application is not only more tunable options in the programming, but the drivability and response time of the engine improved significantly. Gone was the unstable idle characteristics of the stock 2.8 which some have said existed from the factory. Gone was the high idle flare upon startup. We quickly found out that using the 7730 ECM system on the stock 2.8 greatly improved it’s drivability as well as throttle response and performance characteristics. Believe it or not, using the newer computer, even this stock 2.8 ran and acted like a new engine found in today’s new cars! And because the 7th injector, fan switches, and vacuum-controlled EGR valve were no longer required, it also allowed us to clean up the wiring and vacuum lines on the stock 2.8 engine as well…

I think this is one of the most worthwhile upgrades for a stock (or even modded) 2.8. Obviously, it can also be used on 3.1 and 3.4 OHV swaps. Although if you are swapping in a newer 3.1 or 3.4 that has provisions for the DIS ignition system, I would recommend using the DIS as well. The 7730 ECM will work with the DIS ignition system if you use a different code mask (programming).
