Every instance that I have seen on this forum (lots of them) when someone switches from stock ecu to something that uses a map sensor there has always been very reasonable gains over the stock maf sensor.

Alpha N, MAP, & MAF are three different fuel (load) metering strategies and the power production of an engine will be the same unless one particular metering strategy imposes a mechanical restriction.

Take care,

Brian_H- I definitely do not know more than Rob or Christian at COBB I'm a Dealer / ProTuner of their products. But, we are willing to test and deliver a bit more information to the public than most companies would. In the end, I turn to COBB's staff for information regarding their product.

In regards to a MAF, the following is from personal experience and is of my own opinion. The factory MAF has some limitations, but offers wonderful benefits to the vehicle. We've pushed stock MAF EVO's to 475 whp on our Mustang Dyno, roughly 525 on a Dyno Jet. At this level I start to question the strength of the internals. In the end, the stock MAF will accomodate roughly 90+% of the EVO moding community. For those that desire more, there are stand alone systems. It is my opinion that a car with 500+ whp has become more of a race application than a street driven errand runner. Race applications generally accept the fact of running 4" turbo inlets, BOVs, 1000+CC injectors, AEM EMSs', etc. This is what I've seen over the past 4 years of the EVO. This holds true for Subaru as well. They end up going to standalones at the 500-550 whp level. I'm not saying if you have 500+ whp that your car is unsafe and for racing only. I'm just trying to convey the reality that the stock EVO MAF can deliver results for 90+% of the EVO community. For blow through MAFs, speak to several tuners to see their feedbackson them. I've seen mixed results. More results are negative than positive.

In the end, if a person is die hard Open Source then they will not change to a new option, especially if you have to spend $$$ to so. Of course there is always someone that will. Maybe StreetTUNER will open some eyes, maybe not. Time will tell.

I foresee COBB's AP evolving very quickly. It is due to their dedication to their product as well as consumer feedback (such as this forum).

Now, my post is not intended to draw bad feelings towards you. Rather it is to contribute to the MAF discussion. But your continued inquires, although contributing, keep pitting the AccessPORT vs Open Source in a negative fashion. The AP is a newly released product, give them a break Time will sort out everything. in the end Open Source and AP will coexist for the EVO community. And yes, I've read where you support cobb and even sent your ECU to them For that, we all appreciate your help as it has helped the AP evolution.

One gentleman (mrfred) has said that on a stock car/motor/ecu that knock counts of 10 is normal and even up to 25 can happen...but that anything over 3 begins to pull timing.

THis, obviously is not the same thing we discussed...nor did I get that effect from Christian either in my PMs to him....could it be that the AP is registering knock in a different way?

Also, just want to be clear that the ECU can pull timing at knock sums of 1-3 as well. The ECU handles knock sums higher than 3 counts differently though.
