You just call Mike Simard up and say " I want your lightweight flywheel" and he sends a pretty one that looks like this:

Then you don't use anything in the stock system - and the replacement parts are all just in the tilton catalog. Boom - done.

Yes, the 36-1 on the front would allow you to just run-what-you-brung on the clutch side.

Part of the awesomeness of using the aftermarket EFI stuff is the ability to ditch all those redonkulous wires and coils and caps from the engine space.

I did not do anything with my flywheel set up due to the fact that I am feeding ms the ignition signal from the EZF, I have not messed with the oem ignition other than to tap it for the ignition pulse that ms needs to do it's thing.

All good stuff. That flywheel is pure jewelry. Maybe after I pay off the S4 motor .

This post is worthless without pics

This might be the way to get started for me too. Thank you.

Has anyone running M S on a 928 passed the California rolling emissions tests ?? I really do not know..How about Mustang guys ?

Michael, I would recommend either sending your crank pully out to say, Colin for the 36 tooth or order the predone flywheel. You will just need to figure out whether you want the single or dual clutch setup.

As far as smog is concerned, nothing will end up looking abnormal, and the sniffer portion will be handled via cats and tuning.
Otherwise, I will have him register it in Nevada using my address

If you can keep it stock looking, I think it would pass. They don't look at the computer.

UncleMaz

His word meaningful to me, the gentleman who sold me the motor has done quite a few of these and 944 variant swaps/ecu changes with no problems.

Thanks Sean I hope it does not come to that.

I want dual since that is what I already have and want to get max use out of it. So, I take it you don't like the DIYautotune guys suggestion to tap into the EZK for ignition?

I will send a PM to Colin re: His ideas and services.

This is my thinking. Colin also says it can be done totally stock looking.

I need to do a complete budget for the project and pick a combination of best practices and bang for my buck. To that end, I am getting so much valuable information and suggestion here. I really appreciate it.

Okay, I reread the entire thread and see I skipped over that whole thing. If that works then that would be nice to skip over that part of installation.

What did they say about a harness? I think Colin mentioned he could make one if they couldn't. It would take alot of my time down there to solder and run wire to make the harness and would be worth the money for DIY or Colin to have one for us ready to go.

Okay, I am about to place my order for the MSII. They said it will be a custom unit. So, I need to have my ducks in a row.

Besides fuel and ignition, what else will the box be controlling? I now know I need GM versions of AIT and CLT (not necessary but better). Does anyone have a part number on a TPS that will be a potentiometer style that I can use in place of stock? Anything else before I pull the crank trigger? What is the flappy? For now, I am going to go with a tap into the existing EZK wiring system for ignition pulse and add improvements down the road. Thanks.

flappy is the inductive tuning flap inside the intake on S4 engines. It changes the resonance of the intake so there are two torque peaks (Helmholzt effect). The existing brains use a combination of load and rpm to activate it...typically at 3200 ish rpm, and then off at 5500 (I think). The MS can run it by controlling the electrical connector that normals actuates it (two pole connection). A simple turn on at 3200 rpm works for me..

UncleMaz

Thanks Tom. Any other items the box controls on the S4?

I see you are getting solid horsepower above stock. Is that directly attributable to your ability to tune the motor or are there other trick bits in your set-up?

Tom. M

I talked to Louie Ott about the power increase from stock to MS (295 rwhp to 330rwhp) and he figured it was the ign advance and I think the EDIS 8 with large gap plugs probably helped. I still have some tuning to do (took Colin's base map from his 86 engine) and spent about an hour with a local dyno guy (no longer here unfortunately) to smooth out some of the transitions. I'm still learning the tuning aspect and have been playing with it more after recording some runs at our last track event.

Keep in mind you won't have knock control at this point..but it is adaptable to the MS.. I may do this down the road...

UncleMaz

Thanks Tom. Also, thanks for the PM.

Does an S4 stock engine management have knock control? Is knock control something I should have specifically built into the MS at this point? What is involved to adapt to it on the S4? Thanks again.
