have it your way darkscout. I guess you know best.
You asked why some folks still run maf in their car.
I tried to explain why folks still run maf in their car.
You take that and try to twist it into some sort of advocacy position that you can use as an excuse to try and start a "popcorn anyone" conflict. If you already have the answers, why did you start this thread?
There are a ton of folks from 2008 through present with vnt17 or bigger and a speed density (you call maf-less) kerma tune. That's from before your boy even thought about selling tunes, and that's a LOT of happy people. You might be surprised just how many.
And that's a lot of experience too, actual experience in the trenches tuning actual cars for actual people, with a lot of hard knocks along the way. I think I should probably have SOME idea by now what works, and what doesn't. This is from actual practice in the trenches after dealing with thousands of actual cars. What I'm saying is not just idle speculation and posturing behind a keyboard. This is not what fabulous unicorn "might" happen "someday" but based in the practical reality and actual experience in the past and present with many actual TDIs.
One very popular TDI tuner is (or was) only changing the "maf unplugged fault" single value fallback from 550 mg to 1275 mg then going around calling it "speed density". This is the "other" method that mike refers to. But this is not me. I change that value ONLY as a diagnostic aid to help diagnose a bad maf.
Did you know: There are even north american TDI PD software versions with MAP-based smoke limiters from the factory. So speed density is not news to me. My own car (VE) runs a map-based smoke limiter, and has for years. MAP-based smoke limiter has its applications.
Regarding the "shoehorning" comment... As far as I can tell, the only alternative available at this point is talk about what "might" happen "someday". But if there's something else available to actually use today, I will certainly consider it on it's merits.
