Quad 4 2.3/2.4 ICM? Relocation?

[Blue Shift]

Befarrer, you probably know the answer to this one.

I have a 1994 HO Quad and 5 speed I'm going to put in my 2M4, but before I do that I have to get it to start to test it, and the IDI parts were missing when I pulled it. No ICM, no coils. Every 2.3 at every yard I've been to has the ICM missing, and usually the coils as well. WTF? Does anybody know if an ICM and DIS coilpack assembly from say, a 87-88 2.5L or the like can be adapted to work with the quad CPS and ECM? I'd just remote mount it and run wires.

I've read up on people relocating the stock coils, using DIS coils, or even Dodge Neon coils, but it appears that they're reusing the stocker Q4 ICM to do the job, which doesn't help. There's also 2 versions of the ICM, one with 8 pins, and one with 11 pins... I think the 8 pin was 93 and later, while the 11 pin was the earlier motors... Does that mean I can swipe the ICM from a 2.4 Twin Cam and make use of that if a cheaper and more plentiful part can't be made to work?

I *think* that the brains of the Q4 ICM are the same as any other GM 4 cylinder DIS module. IE, you could snag one from an iron duck, run plug wires and it *should* work.

Be warned that if you do that, you'll have to polish the cam towers so it looks like an Offy

Not sure if a standard ICM from a 2.5L or 2.2L will work. I do know that the HO and not HO ICM's are the same. The stock ICM has a 3 wire weatherpack plug on it, so if you do find one, it is easy to relocate, you just have to hook up the wires to the coils. I cant remember what goes into the stock ICM, but as long as all the inputs/outputs are the same it could work. I do know that the ECM used on the Quad 4's are unique to them only, even the programming is quite different from other GM engines (possibly why the ignition is different?), so it may not work.

[The Dark Side of Will]

Part of the reason the programming is different is that the Q4 spun so much faster than anything else GM built at the time.

the 2.4 IDI will work for you. If you need one email me I'll ship you one.

GM always liked to reuse anything they could... Makes engine swaps easier anyways. I always thought that all the DIS ICM's were more or less the same besides differences in cylinders, and would be surprised if there's nothing at all in common signal wise with the Q4 IDI system. Then again, I guess the Quad was a radical departure in everything from how they build the engine, to the design, etc.

Will - I've never been a polishing fan, but in this case I think it's required to bust out the sandpaper and the buffing wheel and go to town...

P8ntman - You got mail.

Things of great beauty... I got to see a Meyer-Drake era Offy come through the shop I worked for, on the way to the dyno for testing, as well as a real Duesenberg engine, also on it's way to the dyno. Just the attention paid to all the little stopcock valves and polishing and smoothing cam tower covers and every last little piece really reflected an era where people were proud of their craftsmanship and put it on display on everything they made. Amazing stuff.

Anyways, a buddy dragged me to the junkyard today where I found an intact 2.4TC IDI cover, ICM, and coilpack, and a Quad OHC, with complete IDI assembly as well. I jacked the ICM's from both, and also noted that the Neon coilpack assembly looks convenient for remote mounting - I'll get a fresh coil and some wires later and do that.

I don't think the Neon coil pack would work. The GM ICM's buffer and interpret the 7x reluctor wheel signals for the ECM. The ICM sees the analog signals from the sensors and outputs digital so that the ECM only sees digital signals.

I think one would be limited to using the actual coils themselves, in place of the original 2 IDI coils or 2 GM DIS coils while retaining the original GM ICM to drive it... Of course that still requires the GM ICM. I think the Neon part is just a convenient, easy to remote mount package that contains 2 DIS style coils in one.

[befarrer]

The neon coils is just the coils with 3 wires going to it. Chrysler ignition control modules are built into the ECM, all you do is plug the neon coils into the GM ICM (wired up properly), and it works. The GM DIS coils are a pain because they are designed to mount right on the GM DIS module, which has pins sticking out that go into the coils, where the neon one has 3 wire plug, with a pigtail, that you splice into the 3 wire coil output plug on the Quad 4/Twin Cam ignition module.
