I was wrong, you are correct. It's been awhile since I looked into the matter and I got mixed up.

Thanks for clearing that up. I'll definitely be using my '99 rack then instead of the MSM one.

So I had a run with my buddy the other night

2012 Mercedes C63 AMG stock 451hp Sedan

0-120 Both spun, he spun more, beat him by ~5 cars
40-130 he said he jumped (I didn't see it) and I pulled a car length away by the end

Bonus: was creeping up hard on his brothers ~600whp e55 AMG, then found out the Benz was in limp mode haha

Pretty pleased. The hunt continues

So some new stuff. Got 949racing motor mounts. Super stiff and vibratey at first, 200 miles later they are much more mellow.

Skunk 2 throttle body and some IM porting to blend it together.

Got a lightly used set of Maxxis RC-1 245/40-15 for the 9" ULs. Definitely need to stiffen up the springs from the current 7/6 to probably a 9/6 or 10/7 setup but the grip is amazing as is the straight line traction. Car is now at the tuner for some refinements and maybe more boost. I want to do track days next year so reliability is important.

60mph pull in 3rd

At 17psi made 311/285
Up to 21psi made 328/328

Unfortunately anything over 21psi breaks up, out of power on the coil module. Going to work with Fab9 on this and hopefully order one soon and then maybe I'll try for more power. The jump in torque is gonna take some getting used to.

Thank you! Correction, it actually made 328/308 still a nice pickup

We are running the FAB9 coils in wasted spark. If we went to sequential, would that perhaps alleviate some issues? Does sequential still use the coil driver?

Worst comes to worst how hard is it to create a COP system that uses GM coils?

Does the module still get used or you don't know? I'm thinking its time to go LS coils next year and perhaps sell these to someone who won't be running them at max capacity.

pretty sure it does.


true seq requires re-wiring for each coil as you can see

I am planning on going to LS2 truck coils here shortly. I was going to wire them up without the Fab9 driver, we'll see how that goes. I don't see any mention of drivers on the write ups for the LS coils but maybe I'm blind.

So picked it up from the tuner. Feels good except the spark issues. You can hear it in the speedo video below. Besides that the car pulls hard and feels fantastic! I'll take it back once I get the new coil setup and it should have no issues.

Thank you thank you. The ignition woes are definitely still here and seems to be happening once I hit my 20psi mark no matter what gear or throttle position. I'm going to start working on the LS coils in the coming weeks and install. Even if I don't get to tune for more boost this year ill at least have good drivability.

I actually took my Fab9 COPs off in preparation for my LS coils and I am currently running the factory coils @20.5psi with no issues.. I was surprised to see that they are holding up to the boost. maybe your timing is more aggressive then mine, though.

I think that more timing and less fuel would actually help not break up, at least from what I've seen

I have the 8.6:1 compression Pistons and recall my tuner saying he ran less timing than expected. I've long ago sold my stock coils and wires so ill be working on the LS setup sooner than later. Does it require a module of some kind? I want to run sequential too.

now that you mention it.. That does make more sense the way you said it.

I have the same compression pistons, I was just going to wire my LS2 truck coils in a wasted spark configuration without a module. I'll be running the D585 coils mounted via tabs welded to a 99-00 valve cover. How are you planning to mount yours?

I am going to run my MSM valve cover. Darkcambria lives around my neck of the woods and has a spare harness and made some kind of bracket to hold things in place. I'll probably just replicate that setup. I have never seen one in person and don't know about them, just that they work.
