max hp is limited by the version megasquirt(built in sensors) or by the modules for boost control, pretty much unlimited for your application
ms has done 2 step, anti-lag, coil packs on different setups
can check out different setups here http://www.msruns.com/index.php
tuning is as hard as you make it? you cant exactly use other peoples bins for your setup, ms seems to be more specific to your own stuff
going to be alot of wiring until diy has the pnp module

I started reading into megasquirt, the more you read the more you realize how awesome it is. But when you first start reading posts you feel like a retard in calculus class, then once you start understanding wtf they're talking about things get easier. Still a lot of research i have to do.
But like everything, you learn by doing, you cant predict problems your gonna encounter, i would just start putting it together, and tackling your issues one by one. Same thing with when your setting up/ tuning the car. Its much easier to remember it when your entering the values and they mean something toward how the car runs, not just skimming and reading. It is a DIY ecu, but the one thing they have done is matched it with TONS of support, and addressed issues for very small percentages of users. Seems like they dont leave any group of car owners behind.
Just wanna say that is a very tough thing to do with all the options out there, and that DIYAutotune is a great company that really is in it for the everyday joe smo,.

so My question is, how are people handling trigger wheels (edis setup)
from all I have seen people are taking their crank pulleys in to have them machined and have the wheels pressed on to them. my stock wiring is corroded, falling apart and causing all kinds of short issues that I do not wish to deal with and I plan on removing it all when I fab my wire harness for ms2 this december. also trying to avoid the machining if possible, the machine shops in my area are pretty expensive

Haha I felt the same way, it was a bit overwhelming at first, but after you do it, you realize it isn't that difficult, and was definitely worth it.TanManS14 wrote: I started reading into megasquirt, the more you read the more you realize how awesome it is.

Feel free to flame me. I'm prepared:
So any of you here running the CAS KA24 dizzy with MS? I'm running a CAS Dizzy out of an 83 280ZX Turbo on my 78 to control spark with great results. I understand it's not the greatest resolution but IMO the benefits of EDIS didn't really outweigh using what bolted right on the car.
Also, there's only one guy who makes a CNC'd trigger wheel and sensor bracket for the L28 and it's a bit pricey.
Also it's so freakin easy to wire it up to MS which is good for first-timers. My diagram looked almost exactly like this:

Have you had any kick-back problems on start up with the stock cas wheel? I'm going to swap in a dsm cas wheel (direct bolt in) if i can find out what year/model we can use.

I'm not sure what you mean by that.
I'll tell you this though, I went from having to either set my throttle stop really high and have a high hot idle or set it lower to get a decent hot idle.
I am running a shaved manifold with no IAC and MegaSquirt has been an absolute dream. Startups have not been an issue.
My idle is rough right now as I haven't got a full tune on it yet [Slipping clutch and my LC-1 controller is being a whore] but it runs really well once you hit the pedal.
I also still don't have the goodies like Accel/Decel switched on yet. I took my last final yesterday so now I can finally start narrowing down my tune.

If it picks up an optical signal, you can use the home window pattern out of the KA dizzy.
Basically, the KA dizzy has the home window, and trigger signal window. Home is 4 slots, one for each tdc, and trigger which times the cam relative to the engine. This lets the ecm know if you are in intake or exhaust stroke.
You guys are getting kick back from only using the home window which is a really basic signal, and injecting fuel and sparking on the exhaust stroke.
That optical dizzy is REALLY universal between jap manufactures, and almost any trigger wheel will fit in any cas enclosure. There are also aftermarket wheels made by Mazworks and AEM to simplify the trigger window pattern so aftermarket ecms can read them.
I don't know if the Megasquirt can run a Home + Trigger optical, but from all the nissan related wiring I have seen, it can at least run optical home.
Taking all this into account, the accuracy sacrifice is kind of big one in high rpm / forced induction applications, either with the lower res wheel, or just running home window timing. The crank trigger wheel is kind of in the same ball park as this, but at least there are more teeth than the 4 window home.
I would see what applications they have done home + trigger on, then insert the cas wheel from that model. Disc size and key hole should be the same in almost all 80-90's jap opticals made by mitsubishi and hytachi.

I've seen people drop 4G63 trigger discs into the KA distributor before; MegaSquirt can run that pretty well. However, a better solution is in the works - the MS2/Extra team is working on a patch that allows using the 360 slot setup below 1200 RPM to eliminate the cranking kickback issue, and MS3 will use the extra slots at higher RPM too.

First car i ever owned and ever boosted, was a 1989 325is. t3 garrett airesearch turbo ebay mani ford 24lb injectors and a fmu. Those cars will run, i loved mine but i wanted something that was a little newer. It seems like i get something boosted then turn around and sell it. My 325is was delphin gray, idk if i still have any pics ill see if i can find some. And to stay on topic many of the guys who boost bimmers use megasquirt, seeing as there are no readly available pnp ecus. If you need info on tuning go to e30forums . com they can really help, its not the exact same but its may help you work around some issues.
