I'm going to have rails made soon...drop me a line if you want to get in on them @ the same time

Do you have a trigger wheel, trigger bracket yet?

Jonathan,
I meant to ask when we talked about fuel rails, but forgot...

The trigger wheel and spacer you are working on, they are intended to allow fitting EDIS?
If not, what system did you have in mind, or were you just intending it to allow MS or equivalent management to use it as a position sensor alone, and to control the coil directly?

I'm thinking EDIS...everyone on MS seems to like it and parts are Cheap!

Give a ring, we'll chat

Yeah, I might be interested in that. No I haven't collected anything else yet

EDIS is easy to work and works nice but it also makes that you can not use many good funktions becaurse of the edis modul.

You can not set a real rev limiter with a ignition cut.
You can only cut fuel with edis.
You can not control dwell time
You can not use launch and antilag control
And some other funktions.

I think that wasted spark is the best sollution for MS and making the most clean install too

Point noted Roman!! You have far more experience w/ MS'ing Mercedes engines then I do. I'll focus on wasted spark

Jonothan and others, the coil packs from an LSx engine will be a nice option, they have internal igniters and in your neck of the woods they should be easy to obtain. They are what Im going to use on the 119 when I find some as theyre like hens teeth down here.

Thanks James, will make that our 1st choice

Right now I'm looking @ the Wolf EMS units to do stand alone.. Have a potential customer that wants to do the conversion on two cars... So hopefully he'll come around

This has been an interesting thread. It seams the recommendation is to go with wasted spark and both Roman and Jhodg5ck have built fuel rails. What about the intake manifold. It seems the old Djet manifold off the early iron blocks might be a better solution than the CIS manifold. Will the old Djet manifold bolt to the newer heads. It just seams like less restrictive plumbing on the Djet style and puts your throttle body where you can reach it.

Thoughts

hey_allen · #28 09-20-2008, 03:16 AM

I'll have to take a look and see what the D-Jet manifolds look like.

I already had a set of rails built (and forwarded the info to Jonathan), but I got the design from the work that another of the gentlemen here had done, for his 450SLC.

Johnhef · #29 09-20-2008, 08:37 AM

Count me in too as a potential on this. Need people for a group buy or anything yet?

Bluefang · #30 10-07-2008, 09:11 AM

By the way, I have MSII v3 running fuel only on my '74 450SLC atm, U can use a Volvo pressure regulator that holds at 40-45psi, but its very small, cheap and is a inline one that u dont need to worry about mounting, If your too cheap to make fuel rails like me u can use the stock fuel rails and get the ends of the Injectors machined down to the metal core at the end with a barb fitting so that u can use the stock fuel rails(When i get the 350 head to install i am going to make proper fuel rails as i will need to buy bigger injectors to cope with blowing the engine).

If u are going MS make sure u buy the relay board too, makes it a MUCH easier and cleaner install, For my 36-1 tooth wheel i am getting my front crankshaft pulley modified, the ring closest to the engine is not used so having little pieces cut out of it. Will be ballanced too, costing me $70au

The car is more responsive to planting the foot. It also does slightly better on mileage with just fuel, with spark too its ment to be alot better. atm getting about 18-19mpg with a bit of a lead foot. I will have spark in the car in a week or so, once i have all the bits

for a insane SLC

Do u know this guy Pumpish? He is in Sweden too, and its about to dump a 560 into the SLC for even more power.....

And another thing, i thought EDIS was a wasted spark system, 2 sparks at the same time? But either way in one of your videos of your car doing a dyno u mentioned that it was been rev limited by fuel cuts, i keep hearing that this is really bad specialy with a boosted engine, and some people say its fine, I take it u have never had a problem with fuel cuts over spark cuts?
