Stay with a carburetor or go EFI

Don't need peer approval but this is a forum. If we’re not bouncing these ideas off each other then what are forums for?

This is not an emotional decision, trust me. The car is apart. I can go one way or another. If I ever want to go EFI, now is the time.

Carburetors work, don’t have to make it seem like I believe they don’t. I also understand fuel injection is a better mousetrap. But, there are certain things that it can do that no mechanical fuel delivery system can which is datalog and tune itself of the fly. Obviously things need to be optimized for the self tuning aspect to bear fruit but again, EFI is all about real time evidence based off data. Not sure why that’s such a contentious point.

Despite what the marketing may lead you to believe, converting a car from carb to EFI is a lot of work and the initial money outlay is far greater than it would be if I just keep the carburetor.

The other idea the marketing promotes is that you just set it and forget it. That could not be further from the truth. Sure you can rely on a general base calibration to start but once you’re beyond that, things get pretty involved. The software provides the ability to fine tune every point within a range of data and then allows you to switch tunes with a few keystrokes for particular applications. Is that a bad thing? You’re on some sort of computer while you’re viewing this thread. Is that the only thing microchips and programming are good for? Its just another tool, thats all.

But to your point - carburetors can be tuned to a razor sharp edge but instead of software providing a visual representation of what the motor is seeing, you’d be relying on physical testing testing testing and more testing and if you kept notes, log books (aka data) for guidance. Nothing wrong with that at all, I’ve done it. I’m telling you that all the ideas to achieve your “tune” are the same, its just done with software.

The visual representation of the data is key.

You just made my point. If you have to have a graphical representation to do your tuning then don’t waste time with a carb.

I’ll leave you with one last thought. For what you are going to spend on EFI, you could buy a QUALITY carb from some like BLP, Thumpr or Lightning carbs and then invest some money in a QUALITY O2 sensor that you can also log throttle position and MAP and you will be much less money in.

It just frustrates me that guys are willing to spend big money for EFI but they want to spend 600 bucks for a carb and then nothing else. The off the shelf carbs are just that. If you pay someone to build you are carb the results would be significantly different. Then add in the ability to log O2 verses RPM/throttle position and MAP and you can easily get a tune very close to EFI.

But again, I’m not trying to change your mind. I’m just explaining my position.
