An ECU is only as good as it's intended use.
For instance, would an M2 ECU be a good choice to get the car to 500rwhp? No
However, if you are looking for something that is "plug and play", and will get you in the low 300rwhp numbers, then it's a decent choice.

^ like mahjik said, it is a good ecu for basic bolt ons minus midpipe for 300ish hp. if your goals are bigger then a measily 300, a tunable ecu i would keep in mind.

If you have all the bolt on goodie with an upgraded fuel pump its good for 14.5psi on stock twins. The M2 runs on the rich side so you dont have to worry about burning the motor up as much.
Bolt on stuff would include dp, high flow cat, and muffler, air box, radaitor, and I/C. Ive had mine now for 2 years and could no be happier.
Like the other said its a great plug and play ECU but not for radical upgrades.

My car ran way too rich with it & would break up over 6k rpms. I only put out 252hp @ 12psi with all the usual bolt ons. Not a happy camper.
Bought a Power FC & dyno tuned it to 298hp @ 12psi.
M2 ecu adds too much gas in some cars. Plus I still got the 3k stumble from time to time.
The Power FC took care of that too.
You spend more, but get more....

ok, what do you all think if i can get the used M2 ecu for $300? Is that a good deal?
my set up right now is just dp,re amemiya intake, and boost cont. boosting 0.8cm^2kg. Planning to put ic+exhaust.....

Thats not a bad price but you need to find out what the ECU was tuned for. It would not do you any good if all it was for bolt on goodies you dont plan to have or wont have when you plug it in.

350rwhp isn't possible with bolt ons and increased boost with M2 ECU Stage III? No way, I'll be the first one to do it then!!

The Pettit ECU's aren't as conservative as the M2's. Even at 16 PSI with stock ports he didn't break 350rwhp (using the Pettit ECU). However, RTS3GEN has a ported motor using the Pettit ECU and dyno'd at 15 PSI at 359rwhp.
On stock ports, I don't think it's going to happen.

THEY ALSO TUNE FOR STAGE 1 AND 2?

I have dynoed at 284hp with all the goodies in my sig.
And the IC was cold during these runs due to the large vent they put infront of the car. I think it is low, as it is not measured at the wheels. My friend in his tuned 300ZX dynoed at 320hp whereas his mods are good for about 400hp.
So talking about horsepower numbers on different dynos is not relevant
And we are aproximately same in acceleration.
P.S.: John, enjoying every bit of it. Exept for the 3k RPM hesitation I got with this ECU
Doesnt bother me much.

For what you are looking to do, just find whichever one you can pick up used at a good price.

ok, now I am planning to get an ECU, but I am concerned that I only have stage 1 mod done on my rx7. Is the M2 ECU conpatible with all stages 1,2 and 3? or they program the ECU depending on what stage the car has been modified up to?
I am concerned because in future, I'd like to goto stage 2 and 3. But I'm worried if i'd have to get the M2 ECU reprogramed totall of 3 times. And that would suck!
Can anyone tell me if they only have one type of M2 ECU or They actually modifiy the ecu everytime you add stuff on.
And upto what cm^2kg of boost can the M2 ECU manage.
