Here’s where a lap top computer enters the picture. If the fuel curve isn’t quite right, you simply key in new numbers within a table found in the ECU operating software. It’s like changing jets, but without dragging out a fresh set of gaskets, a screwdriver, and towels to mop up the mess. Equally important, with a Lambda sensor, this really isn’t a hit and miss deal. You dial in the numbers you require exactly.
What about the consistency of EFI race cars, especially those that have to race against a dial in or index? Typically, a "computer car" is more consistent than a carbureted example. If the car seems inconsistent, there's a very good chance it was the racer who was off, not the computer. What? That's right. Perhaps the most critical factor in racing a high tech EFI combination is the paperwork. You absolutely must have a quality, accurate weather station. And you have to know exactly what the EFI car will do when the weather changes, even minutely. With that information, you can change your dial accordingly. Other than a high-end weather station, an EFI system needs accurate records. You must keep track of what the car does under varying conditions. Once the log is established, and you have a handle on the dial, you and your combination will be consistent. Simple as that.
Stout? You’d certainly have to say so. Here are a couple of samples from the dyno test. While the peak power is eye-popping, the real key here is the torque curve. The EFI engine makes power just about everywhere. Factor in the ease of tuning and this would make bracket race combination anyone could live with.
