I know this topic has been posted before in the past but i thought alot of guys prob need to hear this again or for the first time.

I recently took a class at EFI University this past weekend. I went in with an open mind, but didnt really think i would learn alot from their beginner class.

I WAS WRONG.

Ive worked in this industry for 7 years. i have been around tuners and dynojets for the last 6.

I feel with their EFI 101 class i already know more than the "tuners" ive been around and that scares the crap out of me. It means all these cars ive seen tuned over the last few years, all the customers, power numbers, etc, i know more about the process of tuning than the people i was subbing TUNING out too.

I learned just how poorly educated i was.

It was the best money ive spent in this field, and i cant wait to take the advanced class next weekend.

The instructor was cool (Chris Marcelloro) , informative, we had group discussions and a demonstration.

If you think you know how to tune, or what tuning is, i challenge you to take even this beginner course because it will open alot of doors for you. It will teach you alot of valuable techniques.

FOr all you NOOBS coming up, take the class, its well worth it an it will make you a better tuner.

i have been planning on taking the class once i get out of school.

anyone else taken the EFI 101 class? I read others opinions and they believe that buying ben's book was almost as good as the class. I have the book "electronic fuel injection" and have read it a few times and had always wondered about the actual class.

 

I bought the book an read it before the class as well. It is NOT THE SAME THING.

THe book is a good introductory to the class, which is an introductory to tuning if that makes sense.

In the book they skim over things we spent hours talking about in the actual class. If you read the book it will help you understand the class better, but its def worth taking the class

 

where did you take it?

 

right down the street from where i live, i got lucky LOL

Forged Performance in Marietta GA

 

every person on this forum will learn a lot in the EFI101 class. worth every penny

 

yeah im tying to take the Advanced class here soon. It was a great experience

 

I also took it at forged performance. Great class. Same instructor as well. I went in the middle of January. Highly recommended.

 

I got my efi-101

Ben's book is a hunk of dog ****. Jeff Hartman's book is thorough and easily puts you in a position to start tinkering after reading it. The end result is tuning is simple stupid guess and check work. The difficulty comes when the mechanics doesn't match up with the theory (ie, bad wiring, bad parts, parts installed correctly, electronics issues, ect.)

 

i liked jeff's book as well. It is a bit more indepth indeed. But that should not go to say that ben's book is not a hunk of crap.

 

Ive wanted to take this class for a while, as Id like to tune my own stuff with more confidence. I have Hartman's book and it is very informative from a tuning noob's viewpoint.

To bad the closest class is 8 hours away.

 

dont worry...the class i took, after lay overs, was about 8 hours away on an airplane

 

I'm so jealous right now, I've been wanting to take that class for years now. Just thought I'd post up too, the course outline this is the intro class and look at how much information it covers.

Man, thanks for this post.. i have been thinking of taking one of these classes for a long time, and i just checked the schedule as a result of this thread, and they will be doing a class about 10 miles away from me in a month.. bad ***.

 

I took it in 2006 at Forged Performance, with the same instructor. What car did they have on the dyno this time?

 

Took this course a little over a year ago with the same instructor. Good class and great info. If nothing else it will just solidify your knowledge. You can't get the details that this class teaches from a book.

 

Here's to that. I'm certified. I do factory calibrations but I went just to see and I feel I left with a lot of gainful knowledge.

 

i heard that was a awsome school.im wanting to go really bad but the classes never come to fl.

 

Hey vteckidd what did they teach you about VE?

Alot, formulas, what it pertains to in terms of power, a/f ratios, etc.

I dont want to give alot away because it is someones business and i highly recommend you take the course.

PM me

 

Just tell me this: Does a turbo increase VE?

I've heard people say this same thing before, but without a specific in depth example of something learned, how do you sell it?
an analogy would be how are you going to buy a cd if you haven't heard any of the songs?
Give us a sample..

As much as I like Jeff Hartman's book, I would call you a fool if you said that you were able to tune anything after having read it. Lots of good basic info but not a whole lot that you can actually apply when you sit down on the dyno with a laptop.

What I would like to know is whether you feel that after taking this class, a person with no real experience could sit down with a laptop on the dyno and tune a vehicle.

I plan to take the class. When I asked a guy at the shop where my car was tuned what he thought of the class he said basically that it was interesting but he didn't learn anything applicable that he didn't already know; that he would recommend you save your money and just buy the book if you already have dyno experience. But I still want to take it.

I remember on the AEM forum when Ben first starting talking about offering the class. It's pretty cool how far his idea has come since then.

Having spent some time reading through archives and keeping up with efi101's forum, I can tell you that Ben would answer your question "no". But that's just another opinion with many credible contradicting opinions.

You learn so much of the WHY and the HOW.

Most of the tuners ive worked with dont REALLY understand anything about VE or Cylinder Pressure or even how TIMING works. Which is kinda scary lol.

WIth the proliferation of cheap or free tuning software it seems EVERYONE thinks they are a tuner. Punch some numbers until you get the right a/f ratio and you gods gift to the dyno.

Its simply not that easy.
