Also you will need to buy 2x v6 coil packs, 2 x 20uF capacitors and get some standard plug leads made up...... Then once you've set up the basic parameters (let me know if you need a map to get it fired up)..... And off you go

Any updates?

Pics here until I'm back at the lap top.

I've installed the fans, painted the splitter frame, started covering under the bonnet in aluminum tape to reflect heat. The lights are now in the body, projector headlights upfront and led at the rear. My dash has finally arrived and I've spent this evening installing the savage switch, etb digi dash, afr gauge and the tyre pressure & temperature monitoring system.

I'll be trimming the dash tomorrow evening to fit in it's

I've made a big decision and decided to give her a nice lick of paint when everything has been installed.

Option 1 ..... Gloss black

Option 2....... Merc silver

Opinions?

"some mods improve your car and make it into something it never was, other mods, however, although essentially the same, are not, and make that car a ricer"

if your car isnt shiny, you dont know what you are talking about, remember; paint shine = knowledge. In order to be taken seriously, you should spend all your money on paint, (and get a dyno reading).
Dont forget to polish it often

I just found out MS1 with the MS1 Extra stuff can run dual EDIS modules with 6 ignition points(3 for each) so I am going to use that. I'm not electronically adept enough to be the first guy with a V12 running COPs on MS3 mobdro kodi. Plenty I've found out have done MS1 on V12's so I'm going that route.

Does that mean you can build an 18 cyl twin wasp radial. You still have 2 plugs per cylinder so I guess you would need 2.

Keep us posted on your project. I have a 1999 SL600 that I hope to do some MS and stand alone trans work on before I take it apart.

I guess it may be time to revisit my M120 swap plans. I'm using the early non-COP M120 with the 4 speed 722.3 for simplicity.

I was at a swap meet this weekend and saw a BigStuff3 Pro SEFI ECU module for $600. Tempting but didn't buy it after doing some research on what would be needed to upgrade to 12 cylinder sequential. Impressive specs though.

I have a bit of work to do before committing to the swap, including pulling the heads and probably replacing some intake valves (excessive leak-down on #11), porting while they're off, and generally checking the engine and resealing as needed. The wiring harness is in full degrade mode, mostly copper strands with very little insulation left so I know why the car was dismantled. Transmission is freshly rebuilt and I have a large case 2.24 LSD diff to complete the drive train.

So: MegaSquirt options? My M120 has the dual distributors and I'm good with that system. Sequential or at least semi-sequential with paired injectors 60 degrees apart would be nice but not essential. Mechanically paired aftermarket throttle bodies in place of the EA units. I like datalogging for tuning but my wide band LM-1 can do that.

I'm trying to keep the cost down and the value up. It looks like a few people have been thinking about this for a while so any options/combo ideas would be appreciated.

Good to see you are moving forward. I don't have any ideas because so far I have only done this with the stock MB computers but I believe it is doable especially with the older engine and 4 speed trans.

Ditto

Price distributor caps and rotors before you settle on using that system. The 96 - 99 V12 ( 02 in the SL600 ) use the same coil on plug as the similar year S420 and E420 . The 95 and older V12 valve cover will probably be different but might be able to be modified. I'd even investigate other engines that have a narrow coil.

It might be tempting to use 2 GM V6 modules / coil packs from V6. Feed it a crank signal then use your ECU to adjust timing.


Sequential only helps idle quality, maybe emissions.

I'd be tempted to put a balance tube between the two throttle bodies to eliminate one engine fighting the other especially at idle. ( I'm not sure if this engine has that already or not. )

I worked at M-B around 2000 and replaced one M120 coil pack - $4000 IIRC. Pretty whizzy though, it used an AC signal through the spark plug (ion sensing) after ignition to detect abnormal combustion (knock).

I can get a pair of caps and rotors for under $300. I'm old school so not too worried about COP.

Good suggestion on the GM ICM, I have a few of those around but it will mostly depend on the EFI system that gets chosen.

Also marginally helps fuel economy but again, not a high priority.

I've synced the carbs on an Espada, two throttle bodies won't present a challenge.

$4000 huh?

List price is $166 each. P/N 000-158-72-03

Oops, that was for an M137. My mistake!

Still, $177 x 12 is quite a bit more than a pair of caps and rotors.
