Screencast: MAF and Speed Density

One thing I forgot to mention in the video is that if you're going to use a charge air temperature sensor (or blow-through MAF's internal IAT sensor), you'll want to zero out the temperature comps by putting '100' in for all of the values.

Another thing i just noticed is that if you were NA you could theoretically still use the MAF's internal sensor and not worry about comps, but then who tunes with speed density while n/a? Nobody lol. For people with no IAT whatsoever (which is none of us), you'll need to use the calibration temperature and compensations.

Other than that it's just a basic primer on MAF and speed density, what they are, how they work and what they're each good for. Also provides a very basic overview of the different options with RaceRom and how to get started setting it up.

More in-depth screencasts covering the tuning of both systems will be available soon.

Yeah Im going to give this a shot

Very generous of you to have taken the time to show some of the basics for individuals to experiment with EcuTek. As EcuTeks portfolio continues to grow of neat things that can be done in some of the advanced mapping features it will be interesting to see what the community comes up with in a year or so now that we have end user access to it.

James i love you, no homo ! thank you so much for this vid. Slowly grasping more and more about tuning :)

So to raise the maf limit the only way possible is having a larger pipe ?

Bigger pipe means it can meter more airflow (more air flow for a given voltage) but also that the air slows down, so it becomes harder to meter at low speed. It's not the slam dunk solution that some would suggest, but it works. I wouldn't go bigger than 3" since any larger would require a reducer into the throttle body.

@jamesm Love it keep giving away the farm!!!

jamesm for tuning president
