Discussion and questions related to the course EFI Tuning Fundamentals

Great information! I want to learn but I can not make it past the formulas. It's like drinking water from a fire hose for me. Is there a way to simplify this at all? If not I should stop here unfortunately. I'm want to learn this and I've watched these videos over and over. I just can't grasp it fully. I completely understand the idea and I'm sure it's doable but I'm struggling. Any help would be great! Thanks

I've had to learn well over a hundred (or two, or three?) mostly for mechanical and electrical/electronics engineering (mostly forgotten now, unfortunately) and all I can suggest is you make sure you've learned the terms well, and are confident in using them, then start with basic formulae and go from there. When you understand the basics, you can then play around with them, re-writing them in different ways*, so you're more comfortable with them.

It's VERY tempting to jump right in, but that can be confusing, and from personal experience I'd strongly recommend you work from the basics on up. Oh, many of the terms use Greek alphabet symbols - make SURE you know both upper, and lower case symbols and their names.

When it comes down to it, it's almost all relatively basic algebra, arithmatic, and trigonometry.

For example, the basic V=IR and P=VI. If you don't know the voltage but do know the current and resistance, you can re-write the latter as P=(IR)I= IRI = I²R, so P= both VI and I²R. That's an example of substitution, where a known value, or formula, is used to replace an unknown.

Tavis,

I'd slow down and take it one at a time. It's easy to get overwhelmed trying to learn it all at once.

Give yourself an opportunity to let things soak in, one part at a time.

Also remember that in practice, we aren't using all these formulas on a daily basis, and you don't have to permanently memorize all of them!

They're great to help learn concepts, why things behave the way they do, why we do certain things, etc., but I don't manually calculate PV=nRT every day.

Once you understand each concept, referring back to the formulas once in a while is a great and important refresher, but you don't have to memorize them all.
