Just talked to RMR
hmmm what is his standpoint on other parts than his, with t he ecu reflash.. i talked to vishnu and he said that even with other parts and his xede, that i would expect similar gains.

Is this reflash, a reflash like they upload the data via some upgrade port ?
Or is it where they remove the EPROM / Flash device from the ECU board, solder a socket on and reprogram the EPROM / Flash in a EPROM programmer ?

Sounds like another great ECU tuning solution!
Man I really wish there were some tuners in the midwest or the east that were involved in this kind of tuning solution. Not that west coast tuners are bad, but RMR, Vishnu, and Works all seem to fall back to the safety net of tuning for 91 octane fuel.I think Vishnu will do a high octane map if you are local and spend time on the dyno. Some of Shivs past comments confirm how much better the car runs with 93-94 octane, and how much more detonation prone the car is running 91 octane.
Anyway, I am truly glad that there are more choices, but really am bummed that everyone gets to pay the penalty for California's crappy gas.
BTW- These comments aren't meant as a slap at Ca EVO owners. I know you guys don't have any choice in the matter, and are stuck with what you can get.

I wish I could answer everyone’s questions, but please give us a call if anyone has questions. I do not want info floating around that is misleading good or bad. Here are a few answers to some of the info above.
-The ECU is made with our intake, down pipe, and exhaust. Other companies’ products will probably work similar.
-The first car Dynode made 225hp, with an intake and down pipe it made 253hp and with the ECU, Intake and down pipe it made 278hp. with stock cat & exhaust...
- The ECU is a flash only reprogram. It does not require the computer to be opened up and soldered.
-The ECU does much more than what a boost and AF controller can do.
Can a boost and AF controller adjust for atmosphere?
Can a boost and AF controller adjust ignition timing?
Does the boost and AF controller have safety restrictions to save your engine?
There are a lot of good uses for those controllers, but the factory ECU can do much more.
-The ECU can adjust boost up to 1.3 bar (19.11psi) anything beyond that a boost controller is need to bring it higher, BUT the ECU has all the parameters for fuel and ignition up to 1.8bar if you wanted. (Defiantly not recommended for stock engines)
Basically what you are getting it is a save - reliable car that halls *** and you don't have to screw around with levels or worry about over boosting or leaning out too much. The car will hit 1.3bar and hold it though the power band. It is also great for cars looking for more serious power (350- ???). It’s a great base to start off of for a lot of other piggy backs and other controllers.
Please give us a call if you have any questions. We did not expect the info to get out so quickly, I will not be able to get the info up on our site for a little while.

Come on now Blair - you guys release an inexpensive (relatively speaking) chip from a reputable tuner located in the middle of the import craze that runs safely on 91 fuel and you didn't think the info would get out quickly?

... just a guess as far as the actual # 's but I wouldn't be so sure that this will be such a big deal. Don't forgret that our ECU is also self learning so there are many parameters that the brain will learn and adjust to on its own ... that's the beauty of running a reflashed or replacement ECU set-up opposed to a piggyback in most cases. I personally am really leaning toward this set-up ... seems like a much smarter & more practical way to go compared to Xede or GReddy EManage ... unless one enjoys constant tweaking with the EManage (EManage CANNOT adjust to atmosphere and other conditions on its own)!, or plans to really mod like craz-e and would rather not pay to have the computer reflashed over and over ... but then again, since the ECU is self learning, only major mod upgrades will call for a reflash.

As far as we've been able to tell, there is nothing self learning about the factory EVO ECU besides mild knock retard learning. We have not been able to isolate any long term fuel open loop learning or coarse/fine knock correction maps. It is very much unlike the Subaru WRX ECU and, therefore, has its own share of drawbacks and strengths.
The Emanage, or any other piggy-back, doesn't need to as the underlying stock computer is still actively handling the factory temp and altitude compensations. Unless you want to change the compensation variables (which is unlikely), there is no compromise in this repsect.
Whatever learning ability exists in a reflashed ECU still exists in a stock ECU/piggy-back combo.
They're are theoretical advantages to reflashed ECUs over piggy-backs, but they have yet to be mentioned. These include raising of the rev limiter, moving of map table rpm/load breakpoints. There are also theoretical advantages to good piggy-backs over reflashed ECUs. This incluces realtime maps switching, user programability, additional fuel/timing transient enrichments, 3D boost control, etc,. The actual relative pros and cons will depend upon application and mapping characteristics, of course.
Just my 2c,
