DIY BL Coil Fix

[doublespaces]

Here is a photo someone sent to me after fixing theirs. Regardless if you think this is causing a problem, they certainly do go down further. As you can see here, the coils are pretty much flush with the top of the valve cover and makes the engine cover sit better.

This is how much shield he removed:

lol ... well thanks for the lecture. 40 years of motorsports endurance racing experience between us, I'm sure we'll probably fuck up the measurements.

Whatever man, nobody was implying anything. But now that YOU brought it up though.....40 years of experience combined and yet you failed to catch the issue. Perhaps you are correct in your ability to take measurements.

Probably why my timing is so poor and all over the place.

Would like to know this. I was also suffering poor timing with these coils. When I returned back to oem coils, my timing has been pretty improved.

I think you answered your own question so to speak.

6- almost 7- months of abuse with the unmodified kit and zero issues leads me to believe that this is all personal preference on fit. Im going to defend bimmerlife tuning and their engineering because who the hell else is being a proprietary leader in the ignition field on the n54 platform? (Besides pr- respect) If you think you can do better than do it. Produce your own kit, sell it to the public. Let them take the piss out of your name over something that has no adverse mechanical effects. Then let us know how you feel.

Well at the risk of "lecturing" and since I have so little experience, I can only speculate. Keeping things simple, the DME sends a shot of electricity EXPECTING it to fire from the electrode to the tip / ground of the spark plug, yet gets interrupted by a "jump" the spark has to make from the end of the coil pack to the head of the plug, I would think it CAN in fact create timing issues. Its the equivalent of an engine that runs a distributor and wires to the plugs being cut midway down, and must jump from point a to point b, before it actually fires at the plug.

Lets get things straight.
1. I have no intention about producing kits.
2. I misfired and found coils dont sit correctly.
3. For all the work I put into a plug n play kit at 500.00 I feel is absurd.
4. I shared with people that do in fact have issues the fix that works for me.
5. I did say that the coils DO in fact work as my timing has improved and no more misfires.
6. Im so happy for you that you have zero issues and feel you got your moneys worth.
7. This is exactly why when I posted I told people to shoot me there # and I would text pictures of what I did to fix my problem.
8. I couldnt, really , really couldnt, give a flying fuck how you feel about me and anything I have posted.
9. Have a nice day

Open forum / free market. People are allowed to talk about their impressions of the quality of a part/kit they purchased. Just because someone is a "leader" in some area (what does that even mean?) they aren't given free reign to produce a poorly designed product. I'd let BL defend themselves if they want to.

I've had no issues at all since I got mine thru the raffle on here, and will say these made a great difference with my car, but if it can be improved I'm all for it. The only issue I've had was with the connectors to the factory wiring harness. I'd still recommend this kit to anyone looking for an ignition upgrade. It's easy enough with a tubing cutter and a razor to get them to seat properly on the plug

Obviously you're incapable of reading your own words; ironically your response was to one where I thanked you for providing the information which you have provided.

Let's debunk your comment on failing to catching the issue. You caught a misfire. Our guys ran 4 track days with no misfires. It's a simple fact. There was no misfire to catch. Easy enough for you?

Now that said, we'll measure and take a look at the coils and see what's going on, based on your comments and Tyler's (as I already said).

Thanks,

Filippo

Your post made me think of this. Just because you can hand tighten all your tires lug nuts onto your car and go a year without a tire falling off doesn't mean it never will.

The way I look at it, if I'm paying $500 a full coil kit it better be perfect for that price. If they didn't want to have the coils included in there kits to be judged as part of the product then don't include it. Stop selling the coils and only sell the harness, then the customers can't complain about coils needing to be modified, but by including in a full plug and play kit and still needing to modify it is misleading at the very least or false advertisment at worst. The gap you guys found makes sense on why some people seem to have BL coils randomly popping up.

 

[fmorelli]

Yup ... but we still need to measure and figure out what's going on with our setups, given what SlowE93 and Tyler have found. Not sure why one of the two cars is working fine, yet others are having issues. Obviously not good but unclear why some work and some don't.

I’m cutting that pieces next week, will see if there is any change. Will report back

I have never had any misfires or timing problems after installing the BL coils, running them at least 10000 miles now! But I did shave down the shielding and both tabs, on one coil to test ,exactly as photos, and the coils DO NOT sit any further into valve cover as compared to my others. I am on plug ngk 95770...Maybe OP has aftermarket coil packs, aftermarket valve cover (they are floating around Ebay cheaper than oem) or maybe those spark plugs you guys use the tip might be a little shorter hitting the coil... I am kinda disappointed that I did hack up one of my coils though.. ..

 

[Alex@BimmerLifeTuning]

@SlowE93 stick a plug into the coil, it clicks once seated correctly. I have no doubts that hacking up the coil you can make it sit farther down in the head but it’s not going to make the contact to the plug any different.

As far as aftermarket, there are several different versions, all which are slightly different. I havent tried them to see which ones work and don’t work. VAG also makes other “red top” coils which are different lengths for different engines.

Do you have a photo of how far it sits in the coil well? Which cylinder was this?

 

[FRNTHVY]

Interesting thread. I have kind installed although not running yet. What I can say is that the lead time was significantly different than the website said when I ordered which is whatever but the fact the connectors fall apart is ridiculous. The first harnesss I had the connector just fell apart. I contacted BL and they sent me a new harness after I had to send mine back (I think and advanced replacement would have been nice considering the lead time). The “new” harness was supposed to have better connectors. Well I plugged the first one in and went to pull it out and it also fell apart. For $500 it sucks to have a product fall apart like that.

 

[The Convert]

Are the connectors still 3d printed?

I will take pics tomorrow, I cut down to where slowe90 cut to, but you showed a pic I just noticed of someone else who cut much more off, I will cut more off tomorrow to see if that makes a difference but I think not, and give pics ...
