read the entire mapecu2 website, lol. if this all works out it sounds like an awesome system... so they're sounding like they're going to produce and support a ra system? i'd be happy to donate my car and time if u need something closer to a stocker to map, all i got is a custom sri, ud pulley, and cat-back, i was thinkin rrm piggy next on the docket, but might wait around for this to come to fruition... keep us posted and ty for ur efforts!

MAP-ECU2 Fuel and ignition control unit
check this out found this--- MAP-ECU2 Fuel and ignition control unit [MAP-ECU2]
http://www.urdusa.com/product_info.p..._id=1260518555
READ THE WHOLE PAGE.
states its can control OEM O2 Sensor/AFR Sensor Adjust 26 x 19 (494 zone) table allowing control over Air/Fuel ratios, even in Closed-loop mode. and MAP-ECU2 controls the fuel by intercepting the signal from the Mass Air Flow Sensor (MAF), or the stock Manifold Absolute Pressure (MAP) Sensor, and modifying using a three dimensional map table based on engine load and engine RPM, or;
MAP-ECU2 can generate the signal internally based on manifold pressure and engine RPM and allows the stock Mass Air Flow Sensor (MAF) to be removed from the vehicle. This may require the use of an external MAP sensor on some vehicles.
What do you guys think?

The product would be appropriate for an NA vehicle, not turbo. Talk to dangerous dan, as he's been trying to get it to work on his car for a long time now.
Also, I've been designing ECU's for years and I can say that a lot of people fall into the trap of thinking that larger tables are better. In reality you do not need more than an 8x8 table to properly tune most engines. This requires careful selection of the RPM/load points so instead 12x12 adds enough that there isn't a lot of guesswork. If you really really want more you can do a 16x16 but it ends up wasting a lot of time since most engine relationships are linear - you're adding extra work for nothing.

this has been on the back burner for awhile. I think I've compiled enough data to get a rough map started, but it will be awhile before this becomes important again. I moved into a new house not long ago and it's taking a lot of my time.
