Stellar piece of kit.

I got this for my 1981 (77 Bandit clone) Trans Am to make it easier to tune from the drivers seat, add some technology to the car, and solve cold start issues. I have nothing but good things to say about the product. I ordered this in 2015 directly from the manufacturer along with the FiTech 40003 Fuel Command Center as well as an Edelbrock 2696 Four-Hole Square-Bore to Spread-Bore Carburetor Adapter. Installation with a friend took about 2 hours including the wiring and rerouting of fuel lines. For full details of the installation, please search "FiTech Throttle Body Go EFI 4 Installed in Project Trans Am" on the web.

Since my initial installation I have made additional changes that include modifying my Quadrajet intake so that I can bolt the FiTech directly to it (Quadrajet intakes otherwise are not compatible to this square bore throttle body) as well as redoing my ignition system using the timing built into the FiTech. The intake modification was necessary in order to use the factory air cleaner base with the FiTech so that the Trans Am shaker lines up on the hood perfectly. I could have swapped the intake to an Edelbrock performer to achieve the same result, but I wanted to maintain the factory intake. I documented this modification on my blog as well, search "Modified Factory Pontiac Quadrajet Intake for Square-bore FiTech Throttle Body EFI" on the web. Ignition wise, I am now using a locked out MSD distributor 2 wire connected directly to the FiTech with the negative side of the coil wired to the FiTech to control timing. Installation is simplified and I can now control timing from within the cabin via the FiTech controller screen.

The support team at FiTech are very helpful and passionate about their product. If you have a problem you can email them and get an answer within a couple days, sometimes directly from the engineers or even the owner.

As the title says, this particular FiTech model provides a lot of options that are invaluable. For example, you can simply use this as fuel injection only (just like the lower model cousin), or you can use this to control your ignition timing (you need a locked out distributor), and they have accessories to maintain your factory fuel system from the gas tank to the engine bay that way if you decide you want to go back to a carb or want to leave everything for resale value sake, you can by adding their Fuel Command Center. For those hotrodders who run catalytic converters, this system can be tweaked in order to keep your air fuel ratio exactly where you need it for your model cats.

One more important note, the screen that comes with the FiTEch system does not have to be constantly used. Once you are done tuning the system you can disconnect the screen and store it in your glove box, or have it connected to see real time information.

I cannot say enough how awesome the FiTech solution is. The only thing that would take this to the next level is if FiTEch partnered with a gauge company like Auto-meter or Dakota gauges, or integrated with a stereo system's screen in the dash.
