Speedfreak426 how does the launch control work? Also I'm going to be using the 1ZZ-FE coils, will I encounter much grief. Also can you stage nitrous.. I have more questions but I'm going to read some more and see if I can figure it out. I may buy my unit in a few weeks. Thanks man... I'm not going to lie I'm a bit intimidated with this but I'm going to go MegaSquirt here is another thread on CelicaSupra. Everything doesn't make sense that I'm reading
yet.

Launch control works by backing off spark timing a lot to change when the combustion even takes place, and it can also interrupt spark completely so it "misses" to get some of that fuel combustion going on in the exhaust manifold to spool up the turbo. You can really set it to do many different things.
To use those 1zz coils, you will either have to build many different circuits for ignitors, and build an extra circuit for a second trigger from the CPS for TDC reference, or wire them up in wasted spark mode with only 3 spark outputs. Or, run MS3, which i have no experience with, but should be able to give you spark outputs more easily than MS2, but you need to use more than just one pickup from the CPS.
As for nitrous, yes you can stage it if you use the MS extra software, I pulled up the settings and took a screenshot for you. You may have to build an extra circuit to get the trigger input to work, there is instruction on how to do this if necessary. I sure hope you do your research so you know what you are getting into!

Glad to hear you got the stock CPS to work. All I have heard is people either going with a 36-1 wheel on the crank or hacking the CPS to use only one pick up. It is awesome that you are using it in stock form.
I did, in fact, use only one sensor from the CPS. I also had to take the CPS apart so I could grind a tooth off of the wheel inside. So in a sense, it is "hacked"
I still do have all of the sensors remaining inside the unit, I am just not using them at the moment, I left them in there, in case I want to upgrade to COP in the future, or if I need to know where TDC #1 is, but it doesn't matter with wasted spark, and you can use just one output easily. I also used an oscilloscope to check the output of the CPS compared with the output of the conditioning circuit to the MS daughterboard processor.
It IS very confusing at times, but you just need to have a set plan on what you want the MS to control and what inputs and outputs you will be using. All of the information is out there, you just have to find it. I found everything I needed, there are just a lot of options. I loved the whole MS build, just because it is an awesome learning experience, and it challenges you to do things on your own. You will never be happier with yourself than when know what you have done, when your engine starts for the first time when you have build the contraption running it!
