Is the Mark 8 80 MM maf worth the money? Running a base tweecer and 73 mm c&l that was on the car.

Worth what money? They are like ~$10 or so at most junk yards.

In any case, it's a **** of a lot better than that C&L MAF you're running now, and is plenty of MAF for the majority of people.

Has that been proven?

You're saying it can't be tuned with a Tweecer?
Yes it has been, countless times. The entire way the C&L MAFs work is to "fool" the stock electronics pack into seeing more air than is really being ingested into the motor and cause the car to run richer. The problem with the SHO version of the C&L is that it causes the car to run 5-10% lean. Every single time.

Sure, you can tune it with a TwEECer, but the problem is that you're still dealing with a stock electronics pack so there are limitations to the resolution and maximum volume that it can handle.

There are soooooo many better options out there.

Yea, but aren't they just "heated resistors" basically? It would just be a number for something to calculate and adjust one would think.

And I was told back in the day, that problem was "solved' by using a mustang sample tube. And I don't know how that really would work, but eh... I have never messed with the tuning or anything, so I don't know.. just things that were "sold" as truth back in the day...

Ok, so the 80 mm maf is good! Is the maf program that comes with the tweecer good or does it need some tuning?

Even C&L warns people that the Mustang calibration tube isn't "right".

The C&L MAF is a good unit.

Just not on a SHO.
Respectfully, I disagree.

All C&L MAF's AFAIK just re-use the stock electronics pack. There are two main reasons why people "upgrade" or replace MAF's, a. the size of their current MAF is restrictive in their application, and b. their current MAF has accuracy or resolution limitations.

While the C&L may solve the size problem, it doesn't solve the accuracy/resolution issues -- in fact, it usually makes them worse. That's probably the biggest problem with the C&L housings is that they cause extremely inconsistent results.

Again, with a TwEECer or other tuning where the MAF transfer function can be manipulated you can make it accurate, but you still run into the wall of maxing out the MAF's electronics.

The biggest problem is not with C&L but instead with the whole marketing tactics behind "performance" MAF sensors as a bolt-on power adder. It's become so ingrained in the aftermarket culture that most people have zero concept of what a MAF actually does and when upgrading is necessary. Most "bolt-on" MAF sensors just manipulate the data being sent to the PCM resulting in richer mixtures when the MAF is in the top 20% of its flow range, and that usually results in a little added power. It's not the proper way to get a 13.0:1 A/F ratio when the PCM is commanding something leaner.

Ok... I think I'm following a little better now... basically when a SHO is @ WOT, the resistors can only give a certian value range, and it isn't much higher than what it would be in say a stock MAF @ 7300 RPM?

Doing the math a 73 is twice the size as the stock, so I can see after only 4-5000 how it could be technically maxed out, and have to be cheated from that point.. and just trusting a pre programmed tune, vs letting the computer figure it out?

I just like to tinker with things and figure out how they work ya know? Thanks again, I always like your answers.. ;)

They aren't resistors but two heated wires. One is used as a constant base value and the other changes due to air flow. I guess the current changes so you could consider it a resistive device.
