They are finicky, prone to change reading values over there lifetime, shock sensitive, etc etc.

Modern hot film MAFs are no more or less prone to failure than any other sensor, including IAT and pressure sensors.

Incorrect. If that were true I wouldn't have a stack of those bastards from replacing them for random side jobs. Car runs like crap? The go-to is always unplug the MAF.

Either way, why all the negativity toward someone trying to do something different and new with the platform? We have obvious expert trolls who like to strut around professing their expertise without bothering to share any of it. I learn by doing, and I will do this. Why? I have a need to run a filter directly on my big single and refuse to pay a massive premium for blow through MAFs that require massive amounts of time tuning to get right. Speed density, which is NOT a hack by any means, is my answer. Whether it be ME or complete standalone. The former is within my budget at this time so that is the route I intend to take.

Quite possibly the easiest of ALL sensors to replace in a car....

You're going to add a piggyback which is going to introduce at least 4 or 5 additional potential error modes. Reliability is not going to get better, especially if you intend on using it in many other cars.

If not, and it is a one-off, knock yourself out (if only in the spirit of learning/experimentation; there is nothing wrong with that). But don't fool yourself into thinking you've designed a better or more reliable system.

I triple checked all my posts. Never once said I knew it all or that my idea was better or more reliable.
I even stated in my very first sentence in my reply that I was speculating and thinking 'out loud' about my idea.

Want to run proper SD?
Either Learn to disassemble or fit a standalone.

Want to only run 1/4 mile races? Run it alpha/n.

End of story, your useless offtopic banter does not add in any way to this thread.

What a fun thread.

Nye hates it though, which makes no sense. The thread is titled "me7.1 2.7t mafless error solution" and thats exactly what it supposed to be about... Roll Eyes

I tune 30r, 35r, 6266, 6262 etc mafless with large (890, 1000, 1700, 2200cc) injectors all the time. I can honestly say id rather setup a maffed car over mafless.  lots of fine tuning for large throttle with no maf. most times ill install a maf to get air over throttle maps close then remove the maf after, patch up dtc's and can hack. Mafless works but you are sacrificing resolution over all and requires a lot more fine tuning vs a mafed car. 

whats the lowest duty one can have with 2200cc? is there a way around the 1.7ms?
