If I'm reading your post right, you're commenting on our data collection equipment and calling it "techno-gadgetry". Well, be that it may, that equipment has NOTHING to do with the setup or running of the EFI. It's merely for as I said, data collection when we do the SSCC events. Other that that, it's for kicks and giggles.

My question to you is, (and not a knock, just a query), have you ever seen or helped setup an EFI fuel table? What gives folks fits is not understanding the tables, what they do, and just plain do not pay attention to what the sensors are telling them. Before you even try to tune a car with a laptop, it is imperative to know what adjusts what. No different than a carb. With a carb, if the car falls on it's face at hi RPM, you gotta know what to adjust. Jetting - not idle mixture - right? Same as an EFI setup. With EFI, you have a base fuel map. The foundation if you will. Basically, the base map is for idle and cruising. You have a map for acceleration fuel, decay, ramping, etc. Just like setting up the acceleration pump shot with squirters and pump cams. You have maps for extra fuel when the motor is cold, much like what a choke does on a carb. You have ignition maps, just like setting the curve in a distributor. Get it? Bottom line - All you need to know is what graph affects what, and you've got it made. How do you learn it? Ask here. I'd be glad to help. And so are others. Besides that, there are guys like Craig Railsback at BDS that can not only help, but can put the car on his dyno and tune it right then and there. This argument about "EFI learning curve" is getting old and tired. Not to mention a bunch of crap. I'm no brain surgeon, and I figured it out.
Someone mentioned cold starts. Yeah, can give you a headache, since you really have a short time span to get it tuned every day under warmup, but how many people have the same fits with a carb and just pass it off with "Oh, she's just cold-blooded. She'll be fine when she warms up." Just need to change a few numbers in the warmup tables.
I'll give you that EFI is not for the light in the wallet. But that's not the point to the original post is it? We all know it costs $$$. Nobody needs to bring it up. The original post asked about the virtues of EFI vs carbs.
