Default Map-ecu

Hey, just wondering if anybody else has come across this? http://www.mapecu.com/files/index.php It's an ECU of sorts that gets rid of the MAF sensor in favor of a MAP sensor which reads to 30psi. It attaches through the stock ECU though which brings up a few questions. Primarily, if timing is based off of the MAF on the Subaru ECU in stock form then??? It doesn't say on that info page if it controls timing. Well, anybody know about it and if it might work?

its a huge ripoff - all it seems to be is one big map to which you will enter a MAF voltage corresponding to the given RPMxMAP value in the table. Although this works moderately well in practice, the UTEC you already have provides so much more functionality than this its doesnt even begin to compare.

The emanage ultimate provides this same ability to elimintate the MAF by defining the MAF output at all areas of operation. The EMU does much more however and the MAF elimination is really just a side feature that some may use.

They want to charge $650 for this unit!!!! Just for that one feature!!! They will never ever ever get that from anyone that has any sense.

$650...I didn't even see where the was listed. That's pricey if it only does what you said.

I believe it creates a "fake" MAF signal by combining speed and density in a 3D map. Your stock ECU still gets the MAF signal, but it has been faked by a speed/density 3D map device.

The point would be to eliminate the MAF, which is an intake restriction. You cannot do this with a UTEC. I don't think you can do it with an e-manage either. I think that can only modify a MAF signal, not create one with speed and density as inputs.

It would take a lot of tuning. It does not seem to have temperature compensation which is generally very important for speed/density, but I really only glanced at the website.

I think there are other better solutions if you are having trouble with the MAF, like a Hydra (speed/density to begin with), or BigMAF, move MAF to charge pipe, etc. I dunno, doesn't sound like a great idea. I think if you really want to go speed/density, you should get a full EM solution that is based on that from the ground up, like a Hydra.

Emanage Ultimate does it Mr. Freon, and it includes air intake temp and coolant temp compensation maps.

This thing sucks- it says it supports real time tuning but it doesn't. Every time you make a change it CUTS FUEL while it applies the change. So it stumbles all over the place and basically just sucks. Just say no to piggybacks, especially this one.

Not defending that product as I don't know much about it but the UTEC is pretty much a piggyback too.

True, the utec is pretty damn powerful for a piggyback- but it wont do a lot of things a standalone will do- Just depends on your level of modification i guess I have way too many mods to trust to any kind of piggyback ecu personally.
