Some people have asked if EFI 101 is a pre-requisite course for taking EFI advanced.
Simply, yes.

Some tuners have already installed and tuned several systems and feels that they are beyond the level of instruction provided by the introductory class.

While the EFI 101 class is entry level, we feel that many of the topics covered typically dispell many rumors and open up many truths about the how- and why's of engine's and fuel injection systems.

It is our opinion that even those with lots of hands-on practical experience in tuning may not have ever learned the fundamental scientific properties behind WHY they do things.......the point is that we feel that while there may be a lot of tuners putting the right numbers into the maps, there are few who actually can explain WHY those are the right numbers.

We know that not everything needed to be a profesional tuner is taught in our EFI 101 class, especially the number one ingredient.......many hours of practice.

However, by taking the EFI 101 course, we find that many learn much about what is actually taking place inside the engine and this leads to totally new tuning techniques and a more complete understanding of engine tuning in general.

Still, there are those who feel they have progressed beyond the need for rudimentary training and think that their time and money would be wasted on such a course. For this reason, we will be offering a "test-out" option where folks can pay a fee to take a test online. If they pass the test, then they can qualify for automatic entrance into the advanced class.

This test will NOT be easy and is not reccomended for most beginner and intermediate tuners. The test will only be allowed to be taken once to prevent someone from looking up the answers afterwards and trying again. The test is designed to test the very limits of one's tuning knowledge and some topics in the test will not have been covered in the EFI 101 class, so they can only have been learned thorugh one's own study of science, physics, and math in addition to large amounts of actual tuning experience.

Here are some examples of questions that may be on the test:

1} Explain in detail how an engine's BSFC affects the injector selection process?

2} If an engine had a BSAC of 7.5, and consumed 1,500 cfm of air.......how much power could it be expected to make at standard atmospheric conditions?

3} If an engine had a wedge shaped combustion chamber with the sparkplug located near the exhaust valve, would it require more or less advance than a combustion chamber with a pent-roof design with the sparkplug in the center of the chamber, and why?

4} If a 120 cubic inch, single cylinder engine had a VE of 100%, and an injector that was capable of flowing 96lbs of fuel per hour at 100% duty cycle, then what pulse width would be required of it at 6,500 RPM under normal conditions of atmosphere and fuel pressure to obtain an air/fuel ratio of 13:1?

5} At the same operating point, what would be the lowest acheiveable air fuel ratio with the given parameters?

Well, these and about 20 other questions of varying difficulty will be on the test, so if you think you're up to it, then keep watching for the upcomming link to take the challenge!

A candidate must correctly answer at least 80% of the test questions in order to bypass the EFI 101 class.

By the way..............the test WON"T be open book!

Good Luck!

 

Dammit...I can feel the brain cells commiting suicide now.
