Your right, but they really didn't affect off road rec vehicles. You still haven't answer my question.... The EPA has ruined most two strokes but then again some would not even buy a two stroke with the higher performing four stroke EFI stuff out now.....
Looking at your other posts, you are probably right, You seam to know what you are talking about, but then again I'm not one of those guys that will tell you what YOU know..... How am I supposed to know what you know?
BTW, I don't feel I'm barging here. And I would like to move this little bickering match to a more fact based discussion... Maybe you and I can post some reasons and examples showing our believes???? We are kinda destroying the OP's thread here...

When you make big changes to a motor with mods, all you need to tune a carb is a few hand tools and some jets. With EFI you might find yourself spending hours, days, or even weeks getting it right. That would be longer than the few milliseconds you mentioned earlier wouldn't it.
I like both EFI and carbs. They both have their place and areas where they shine.

You're already around the price of two carburetors and you left a few things out. The biggest being the ECU.
Did I????
Yes, in many cases you can throw the proper carb on an engine and it will run well with very little adjustment. We were talking about initial set up and tuning later after mods. If you knew anything about carbs you would know that a carb does naturally what it takes a computer and lots of sensors to figure out with EFI. Yes, a carb automatically adjusts to changing weather and air density. A carb may not do it as well as EFI, but it does do it. It's pretty simple really, thin air draws less fuel as it passes the venturi, thick air draws more fuel. So a carburetor does by design what EFI does with lots of electronics.
Yep, I'm well aware of the venturii effect as well as low speed, high speed, transition ports, needle tapper, needle hight, emulsion tube. Etc...

I'll agree the learning curve on efi maybe steep, but once one figures it out, it is beyond easy to precisely add or subtract fuel in any area of the ve.
The EPA has it's hand in everything. And yes, that's your answer.
Manufactures are going efi before the EPA standards require it????
You said tuning carbs was part of your job. So yes, when you claim to be a diesel mechanic it does make me wonder how many carbs you run across while working on diesels.
Sorry, I had to reply in red, it is too hard to copy, delete and paste on my phone while I'm at my second job adjusting a little keihin carb... I'm not lying lmao...
You don't need to know what I know to read my posts.
You missed the point. On that one
I have better things to do than get into a long drawn out whine fest on here.

And on the subject of cost, there are very few applications these days that would require two carburetors. Some very nice power numbers can be made with one carb. Only when you get into max effort drag cars do you have a need for two carbs.
I don't think so.
That and many motor sports racing applications also. For most radical street/strip and drag racing applications a carburetor is still the best way to go. Nobody with an older drag car is running out to buy an EFI setup. Why? Because they would spend a bunch of money and get no performance advantage.

Looks like you're trying to talk about motorcycle carbs, but you're still having a hard time spelling.
Yea mine spelin is alitle off.... Didn't relize that had anything to do with the conversation other than give you something to point out in order to draw attention away from your lack of efi based knowlage. Good thinking, I think it's working lol.
BTW, Megasquirt is the ECM..
Sounds good, but it's usually not that simple. Just learning the tuning software requires a lot of time and you have to work with it regularly to stay familiar with it.

Actually it is that easy.
Is that unusual? Car manufacturers do it all the time.
Google carbon credits. Might learn that car manufacture have to run efi as carbs are not at precise.
Of course not, nobody ever lies on the internet.
Believe it or not I was adjusting a carb
I don't think so.

How about explaining why a carb will make more peak power than a fuel injected set-up do to a cooler charge, then I can point out that you are right however the carb would have to set-up and adjusted perfectly and changed as the track conditions change, where as efi might make a couple horse power less will make more overall because the computer will be making adjustments in real time.... So instead of calling me a lier, how about posting somthing useful to this thread, I will try to do the same...

I'm done bickering here. Nothing I say is going to change your mind, and much of what you're typing isn't worth reading. The fact is, I don't really care if I change your mind.
The more you type the less sense you make. It seems like if I quit typing you might take both sides and argue with yourself. Perhaps there is a pill you could take for that.
I'll leave you with this... At least I'm open minded enough to understand there is a place for both.
Yes, I own tuning software and have two LSx EFI cars I use it with. I've also tuned several other EFI cars besides my own.
Yes, I own and tune several cars with carbs and they run very well. Actually my carbureted cars are more fun to drive and have much better throttle response. I have a big block with a Holley 1050 Dominator carb that has better throttle response than any EFI car I've ever been in. It's also quicker than any EFI car I've ever been in.
So, you can love hug and squeeze your EFI.
I'll use both EFI and carbs, and I like it that way.

BTW, there are a lot of really good EFI tuning guys on here, I bet if you post up some of your stuff someone might help you get it running right....

Nice, I was just pointing out a few things..... One, I understand one of the theorys why carbs make more power. Two, I understand why EFI makes more sense on a day to day biases. Three, I was hoping by posting this you would see how normal people would chat about their opinions. Four, I posted all of this in hopes of getting you to post something useful instead of name calling..... I failed.... ...
...
Your "one" theory of why carbs make more power doesn't make sense, but I chose not to respond because you are only here to argue. If anything EFI probably gets cooler air due to the fresh air intake most come from the factory with these days, plus the plastic EFI manifolds transfer less heat to the intake air. But I didn't want to challenge your statement because it will just go on and on, never ending. Please, just let it go.
You aren't here to show how normal people chat, you are here to argue and that's all. Yes, EFI is better for a daily driver, nobody said it wasn't, that's where EFI shines. But a carburetor will also work fine on a daily driver. Carburetors worked just fine on daily drivers for many many years.
The subject isn't motorcycles. We are talking about cars. When you try to convince me you know all about carburetors, but you post about a motorcycle carb it tells me you don't have a clue about a carburetor you might find on a car. It also leads one to believe you might not have a clue about carburetors at all.
You seem to operate on the idea, "If you can't dazzle them with brilliance, then baffle them with BS".
And my stuff does run right azzhole. You can't catch it.

You started being hostile with your first post. You think you know it all, but most of what you post is BS. I never called you an idiot, but it seems the shoe fits. You should start a self improvement program by first learning to spell. You will never look very credible if you can't spell the BS you're spewing.
and see if, maybe, you provoked it???

I don't recall saying anything of that nature. Your memory seams to be letting you down, maybe there's a pill you can take for that.....
You seam to know it all about everyone.... Crazy...
BTW, the self help spelling seminar will be held on Wednesday nights at 10:pm. Think you can make it?
I'm just kidding. I believe you know how to spell *******, but think you need to change the spelling so the forum will allow you to post up your name calling....
