Emerald M3DK

[old captain slow]

Just about to fit one of these jobbies in Will's car. We are fitting the "new" 1600K SS this weekend. The instructions seem ok, but ....

 

The old engine was a 1400K SS. In order to check everything out and confirming all the connections are good before powering up the Emerald, I'm contemplating starting the new engine up using the old MEMS 1400 unit. Just on idle of course. Can't envisage that this would be a bad idea. Can you?

 

Cheers!

The flywheel pattern may differ between the two engines, so the 1600 may not start with the 1400 MEMS.

I went from a '96 1.4SS to a new 1900K, and the wiring loom wasn't immediately compatible with the M3DK. If you're having problems, check that all 4 injectors are working as mine was only firing 2. This required a simple splicing of wires on the injector loom to get them firing in pairs. Karl @ Emerald should be able to point you in the right direction, as I don't have the exact details to hand right now.

Ah right. Thanks. I'll check the position of the flywheel sensor on the two engines.

You need to check the cutouts on the back of the flywheel - the 1400's are different to the 1600/1800's and the injectors on the 1400 are fired in batches of two whereas on the 1600s there not (or the otherway around)

Ok - sounds like a non-starter then (oops!). I'll go straight to the Emerald.

Is the flywheel from the 1400 engine, or is it a 1600/1800 version?

We have two! One on the 1400 still and the other which looks identical is apparently a lightweight flywheel that came with the 1600 engine originally. I can't see any difference between the two. Am I about to make a time consuming mistake?

The 1400 type has 2 missing teeth in the pattern, 1 each missing directly opposite each other, eg. at 0º and 180º. This setup will work with a 1400 mems, and definately only where a distributor is fitted, ie. not wasted spark distributorless ign.

 

The 1600/1800 has 4 missing teeth, 2 missing together, then usually 2 missing approximately opposite but separated by 1 or 2 teeth (not missing!) - this enables the mems to know which pair of pistons is up or down, but is not relavent in a distributor setup.

 

IIRC the early 1600s had the same flywheel as the 1400s - someone else may confirm this?Whichever size of engine it came from, it should be fine with the 1400 mems if the configuration is as the first example.

 

If you're using the bigger (straw coloured) injectors and the 1600 FPR, the 1400 MEMS setup should be pretty close anyway

Just looked at the new flywheel. It's got 2x1 tooth missing with a gap of 2 teeth on one side and 2x1 tooth missing with a gap of 1 tooth opposite.

 

I guess I'll just go straight for the Emerald installation and hope for the best. I might give them a call just for a bit of comfort.

 

Just started assembling the engine tonight and fell at the first hurdle as the blasted windage plate is full of fatigue cracks around the bolt holes. It's come from the old engine. Is this a common occurence? Ordering another from Caterham tomorrow - I suppose it's an essential component. I'm dumping the foam re all the threads a while back.
