Hey guys, I just wanted to know, what's the maximum amount of power the stock MAF sensor can handle before I have to upgrade the ECU to an AEM for example?

 

Over 600 whp, so you're a long ways away from needing to worry about it.

 

Really 600. I thought it started to max out around 400 or so. The shop that I go to, the owner told me that around that power range it's good to get an aem because your MAF sensor starts to max out and you can't tune the car to its full potential. Is this true or is he just trying to get me to buy a $2000 ECU upgrade?

 

He might just be clueless which is even more scary because that probably means he really doesn't know much about tuning Evos. At any rate, there are tons of people who are in the 400-500 whp range, quite a few in the 500-600 whp range, and several who have surpassed 600 whp using the factory ECU and MAF. As knowledge of the factory ECU programming increases, these numbers will continue to grow.

 

Mellon is making over 700WHP on stock MAF. That shop owner needs to be told!

 

Wow I'm kinda suprised be3cause the owner used to own a 2003 EVO 8 and had alot of work done to it.

 

doesn't mean he knows a ton about it. I've got buddies that are 'car guys' and have owned lots of modified cars, but didn't really know anything about them.

It could also be that he doesn't frequent the development stuff, who knows.

 

Invite him to read Evom.net !

 

I figure lots of shops just don't have time to stay on top of the evo scene in particular like they should. when I joined evom several years ago I was being told you cant' go fast on the stock mas too. I was told the same thing on the 3000/Stealth platform too, sometimes you have to ignore the gospel and just give it a try anyway
