Mervyn,

What I did was modify the stock COIL WIRE. Only the COIL WIRE needs to be modified, the plug wires from the distributor to the plugs stay untouched.

To modify the coil wire, I cut off the end of the boot that normally connected to the Bosch OE coil. Then I took the parts supplied with the Accel coil and added it on to the coil wire I just cut. This allows the original coil wire to connect onto the tower of the Accell coil. Thats it.

I gapped the plugs at 1mm on my wifes car. Runs great.

There are many opinions on this board. Take them as you wish. Some people are purest who only will do what MB designed from the factory. Thats OK.

Then there are people that love their MB just as much but don't mind tinkering and experimenting on them. Hey, its your car, go ahead. Thats OK too.

Just keep safety and reliability in mind.

Good luck.

Hi David, about the COIL WIRE, I'm sorry I did not read your messages properly, but I do need the info on the coil wire mod. Its really helpful, thanks!!

I enjoy reading all the views in this forum. Nothing beats engaging in a good discussion, especially on MBs. I belong to the category of drivers who enjoy tinkering around with whatever that can be improved on a 4-wheeler, and I find that the learning curve is always steepest at the beginning.

Nevertheless, you guys can be sure I'll keep the fire going. Till my next mod, seeya!

Cheers!!


Mervyn

Amen.

Donald, Everyone,

My apologies if my posts seemed like they were meant to steal someone else's joy. Let me explain that I sell parts to put myself through school, and all day I hear people talk about how they plan to modify and "improve" upon their car's already incredible design. As a result, they often come back to buy OE or equivalent products to replace the ones that they butchered or discarded after the "upgrade". I wasn't trying to steal someone's thunder, just the post probably caught me after a double shift at work(Retail parts that means 8am-9pm). Sorry if there were any misunderstandings. As for the recheck, I want to feel sure when I give an endorsement whether good or bad about a product and that is why I would try the other coil that I had in stock.

Why is everyone so sensitive on this Forum? Granted, there are some replies that attack people. However, it would be pointless if all opinions were pretty one-sided. It is good that the Accel ignition coil worked out for one but, I also want to hear problems if, someone who did not get the same experience. It is great if, one can help out with others. I think objectivity and help is the key point not, you disagree with me so you're offending me. What is that?
Don't take it personally if, someone disagrees with another. It is only worth 0.02 anyways.

I second the motion.

Adam, still eagerly awaiting your pics of your new Accel Super Coil......

Mervin, I still have the OEM coil where it was originally mounted.
Here is where the change is made.
The coil wire from the OEM coil plugs into the Jacob's Interceptor Module.
A second coil wire comes from the Omni Magnum Unit to the coil position of the distributor cap.
This is where the ignition system from Jacob's inputs their high, constantly variable(depending on the resistance of each spark plug) secondary voltage.
To increase the secondary output of the triggerring coil would have no effect upon the output of the Omni Magnum's coils.
You could use a high performance coil as a trigger, but it would have no added output from the internal coils of the Magnum.
A plus feature of the Jacob's product is, should the Jacob's unit fail(pray NO), you simply return the original coil wire from the coil to the distributor cap and you're off running again, Stock ignition.
In reading all of the comments relative to using a higher output coil, a coil is a coil is a coil.
I see nothing special about the OEM coil.
The name of the game in coils is the turns ratio between the primary to secondary windings and the cooling media.
To add that higher output coil in hopes of more output from the Jacob's, NOPE.

Clauser, your question was addressed to me for an answer.
The question, will it work on your 190 2.6?
The ignition coil is independant as to the number of cylinders, provided there is enough dwell time to saturate the secondary windings, or the size of the engine it is applied too.
The coil in question has a very attractive housing, but the truth is the turns ratio between the primary to secondary windings.
Some years past while a member of The BMW Motorcyle Club of America, a test was made to determine the best replacement coil for higher output voltage. This test was also made by Hot Rod Magazine for auto engines.
The best coils all had a 400:1 turns ratio and the coil of choice was a K-Mart replacement coil.
Don't be blinded by a pretty package or high price tag. Inquire of the turns ratio.

Donald,
Are you saying that K Mart and OEM coil are just the same
as the fancy and expensive ones?

Don, thanks for the advice, its great!

Adam and David, what is the turns-ratio for the Accel Super Coil "140008"? Is the turns ratio usually printed on the coil housing or packaging?

Mervyn

Mervyn,
Just got my Performance Products catalog from Imco the other
day. Jacobs Omni Magnum is $275.15 there.

Hello Gang, what I said about ignition coils was, all coils is da same in design.
They all have a core and primary and secondary windings. Some have frames like a transformer, with Es and Is.
The output of the secondary is the stepup from the turns ratio.
The higher output coils typically have a 350:1 or 400:1 ratio.
If you inspect your coil, you find the output or tower terminal and a supply in terminal and the second terminal to the for control.
I can see no reason why I wouldn't try an El Cheapo coil if I didn't have the Jacob's System.
Coils like the Accel, Mallory and others have a very attractive package, but it's what's inside that matters. Their outer housing shame helps cool the coil as well as make it pretty.
Except for magnetos they all are similar to identical.
Many of the newer solid state ignition systems use a air cooled instead of oil cooled body.
Unless there is something I've missed, Please let someone enlighten me.

I was having idle shakes and weak engine pickup. Slow starts too. Thought the coil was a good place to start...then saw the posts on the weak M-B coils and found the price! HELLO! Did some searching and found the Acell article. Put it in thinking $60 total was a good bet and this thing rocks! My 1990 190E 2.6 runs much better...gas milage seems better too. Still have to usually start it twice in morning, but I think that is maybe the cold start valve or maybe old wires ( 106,000miles on orig wires)
Acell went in smooth to orig location, wire converted to accel supplied connector easy. Excellent!

Hi guys,

I just took a look at the factory coil location in my W124,
how do you guys fit a Accel coil in there? ( I am assuming you guys are talking about the big huge yellow one)

Thanks
