Really? How is that? Both have 4 cylinders living under massive boost. Mine however has a much more efficient way of intercooler being that I use pressurized lake water for cooling. I also have sequential fuel injection instead of Batchfire injectors hoping that their plug wires aren't breaking down or the distributor cap is void of moisture. The replacement cost of my engine is over $6500 at the dealer, $1700 just for the wire harness... I can buy a Used Porsche for that amount. I found 8 pages of them on AutoTrader.com at that price.
Lets get back on topic of how to tune a MAF via ECU tweaking. I am using examples. Tried & True examples of how to make it work. I'm not even saying the A'PEXi is doing it the "Cheap Way" more than I am saying it is a viable option to drastic mods like standalones or ECU swapping.
Think about it like this... if these newer piggybacks are working with later model feedback OBDII ECUs then they are a cakewalk for the older stuff. Don't let the cheap price fool you. These things are marketed with KIDS and their HonDuhs in mind. By offering these parts at a lower cost they sell a bajillion of them compared to the high dollar Motec systems that do the SAME things. If it accomplishes the SAME goal... does it matter what the sticker on the side of the box says?

Yes... I was at MSRH before going to Sebring and was supposed to go Mon & Tues of this week for the Andretti testing but was rained out. Sam's Great! Haven't seen him in a while. He is probably one of the best Porsche Tuners other than my brother I have ever met.

The Tech 3's, and MoTeC, use straight forward mapping. And of course give a ridiculous amount of adjustment room...
Now, that said, YES, you can still make big power without resorting to this. As long as you don't have a faulty harness with crazy shorts like mine had.

honestly i can get any maf sensor for free. so im flow testing them seeing which one has the closest curve to the afm which might be fox body or cobra mustang maf. then if the curve is close enough i think an safc might fine tune the signal enough to work well

im gonna try and find an Iat for free as well that has the same resistance table as the afm Iat and put that in the plumbing or just rip the iat out of the afm.

no density is a big thing and temperature changes density. iat is very important with a maf. it has to be at least i know thats the way these newer computers work altho it is an old one. well i know its at least important for the dme.

air passes over the hot wire and the amount it cools it pretty much tells the airflow more air the cooler thats y the comp needs an iat to compensate for weather change. so yeah the maf sensor will change temp. thats how it works. if u didnt have the iat in the winter the car would run rich.

I messed around with something a bit better than a random MAF and IAT (ARC-2 Huntley Racing MAF kit) and it sucked. No 2 ways about it. I wasted A LOT OF TIME.
I bought a Vitesse MAF kit, spent 30 min installing it, and have been enjoying my car ever since... it's the best way to go.
