I think part of it is that no one has tried it. If I remember right, it's a 7 pin connector, and 6 pins are used. 2 pins for the ignition channels, 1 for 12V, 1 for ground, 1 for crank trigger input, and 1 for tach output... I don't yet know which pins exactly do those things... but I'm working on it, and it should work in theory. Everything the module needs, MSnS can supply.
Time will tell in a couple of months when I crank my Ecotec over. If it doesn't start... well, we'll have the answer to our question  ------------------

I may have the diagram you need, I'll post in a little bit if I can get ahold of it again

wftb- correct me if I'm wrong, but it looks like you've taken the ECM 'entier' from the cavalier and even the ignition switch and guage cluster. I presume that this allows you to use the stock ignition system as well? Will we not always need the eco's brain box to run it? I mean it sounds like we might be on the cusp of figuring out how to rig the MS to make it go, but my question is why we can't just make the Cav's ECM talk to the fiero guages? Is it as simple (ha) as routing each and every wire form the ECM to each and every applicable wire from the fiero's chassis electrical system? I seem to remember reading up somewhere that that's how the 3.8 guys do it, piggybacking the 3.8's brain on the fiero's accessories and guages. Are the inputs/outputs so different on the eco that they are in no way compatible with the stock fiero guages/chassis? ------------------

Oh- and I wanted to ask as well, is it possible/feasible/worth it to make a 2.2 that makes 200hp without blowing it or turboing it? ------------------

my ecotec engine is run off of the cavalier ignition ,ecm ,bcm and wireing .the fiero computer is not in the car.i use the cavalier instrument cluster because it plugs right in to the harness.i am not much of a computer person ,so i dont know if the fiero gauges can be blended with the cavalier ecm/bcm .my main goal was to make my fiero run with this motor ,and make it perfect later .so in my car the cavvy ecm/bcm will probably remain intregral.as for making 200 hp normally asperated ,i think that would not be hard unless you have nooo money .

I really have no idea on four bangers, what kind of mods would you have in mind to do that? Would it still get good mileage if you nursed it? ------------------

From what I have read (quiet a bit) 2.2 ecotecs can get up to 250+ hp easy with a gm supercharger kit. The 2.0 ecotec comes with a supercharger and is 230 or so from the factory, with a stage 2, it puts the motor up to 250-260. Ecotecs the best way to go.

That's crazy, man. Of course, I'm sure you're looking at a hefty chink of change for one of those blower units. What else are they doing to the engine to get those kind of numbers? The coolest part is that they still are way lighter than the original engines and any other iron block engine used for swapping. I'd like to see someone produce a kit made from wftb's mounts he fabbed, if it was comparable or less than archie's V8 kit I'd be all over that like fat on cheese.
cheers

i think 200 hp out of the 2.2 is do able with headers , better intake and throttle body ,custom exhaust and better cams .my plan is just to hang a turbo on mine , maybe next winter.i dont want to do anything that requires engine surgery .this motor ran really strong the way it was and with the better exhaust i am putting on it will be even stronger.i priced out a g-tech unit down in London today and i am going to get one before spring and then i will have some performance numbers to post.
i think the supercharged moter would be great .the kit is 2500.00 plus shipping .i think i can turbo for a lot less than that.plus once they start showing up in the wrecking yards , it should be cheaper to buy a whole engine and transmission than what the supercharger kit is going for.if GM would hurry up and put the supercharged motor in more cars ,the price would drop in a hurry.
as far as kits go ,i talked to Lloyd at Fast fieros and he doesnt want to do a kit until he has done some turnkey jobs and he has been too busy to mess with the ecotec.ceticars has a stand alone wiring harness and adapter plates are available to use the stock fiero tranny .of course that drives the price up .

I re-opened some of my research on MSnS with the stock Ecotec ignition control module.
It seems the "IC Timing Control A" and "IC Timing Control B" are the missing factors in getting the stock module to work.
What's needed is a square wave signal. All I need is to figure out the frequency and the amplitude.------------------
