Re: What ECU for 20v!
There are a number of options out there. I am only familiar with a few and only on a pretty surface level. I know the most about MS but still don't know a lot. I have been about halfway through a MS3 build for about a year and a half now. I need to get the daughterboard before I can finish it.
The MS3 is awesome and has more capability than most will need, The main reason I went with it is the ease of doing sequential injection and the fact that it can be setup for internal knock monitoring and the knock module is supposed to be pretty good. I haven't read much about real world testing on the knock module though.
MS2 is enough to get a motor running quite well and do everything most people would need to do.
The DIYPNP requires assembly but plugs into a stock harness. The advantage is that during tuning or as a failsafe you can always plug your ECU back in and get around on that.
The MS PNP is a little more expensive but comes assembled.
I have been hearing a lot of good things about the AEM EMS4 lately. It should be able to do everything almost any 4 cyl owner would need and is a pretty great price.
I can also get a Tweaked plug and play harness made for it if you wanted or if you want a cleaner install you could get a whole engine harness made for your motor/chassis.

There is a great MS comparison here.

And a lot of info on the EMS4 here.

Thank you so much yoshimitsuspeed! I think I will go with the EMS4 it seems like a really good ECU. Once again thank you!

No problem. That's my website. If you can find it cheaper let me know and I'll see if I can match it.

Re: What ECU for 20v!
Would be worth checking with AEM if you intend to use the stock 20v magnetic cam / crank sensors with the EMS-4
In fact you would be much better off getting a crank signal from a hall sensor when using an AEM EMS
Sadly the AEM forum has disappeared, there was a lot of info. regarding sensors on it but the general opinion was that the Hall sensor signal worked much better than a magnetic sensor signal.
AEM ecu's are ok, I've been using one that was originally a plug and play unit for a Mitsubishi evo VI it was a bit of a trial but far easier than translating and subsequently tuning a Japanese Freedom ecu that I had before. Personally I prefer Freedom ecu over the AEM when it comes to the 4age but you are on your own when it comes to tuning it !!
