Ignition writeup for the LD9 2.4TC
Tuesday, May 10, 2005 12:43 PM
Instead of taking up all kinds of space and bandwidth, here is the page for what was done to the 'blu's ignition system.

If anyone has any feedback on it or needs some further explaining, please post and let me know.
The more feedback I get, the easier it will be to make changes as needed.

I'm very hopeful someone else does this and can utilize this for their car.

If you don't mind doing the work and some fabrication, well worth it and believe me, the stock 2.4 coils suck bigtime in comparison.
Hopefully someone else will do this and prove me right and confirm my findings.
Good luck to you if you do this and will improve your times nicely.

How so?
What's the output of either system?
Whats the winding ratio?
What's the current draw?
Any other info you can add to justify this statement?

Quote:

It's been proven to work on my daily driver with more spark energy, super throttle response, a 2mpg increase for every tankful, and a guesstimate 10-20 hp added as a benefit.

GUESSTIMATE?!?!?!??!?!?
Any real testing done on this?

Quote:

The hp figure is a guess as the butt dyno really tells me this is the best mod added to the car yet.

Oops, spoke too soon....... now we really do know.... it must work.

So you are still waiting for some kind of proof to?



Nice web site though.

You know what the problem is with the JBO, you don't know squat about tuning, nor do you know what is going on with this ignition setup.
It pities me to see this as the once great JBO has fallen down on it's so called ppl that think they know what's going on.

I knew this would get flack and accept it.
Maybe someone will actually read the writeup and see what was done and how it has affected the performance of the ride.

I really thought that this information would be useful to those that don't mind doing things for themselves and having a custom ignition mod and not having to go out and buy an MSD. Maybe someone will.

Dave, take me off this JBO, ban me, I don't care.

There is no respect given to those that are innovative with designs and get nothing but flack from the posters on this forums.
Asking questions like the ones above would put me at an engineers qualification and no, I'm no engineer but know a good mod when I do one.

I'm out.

Your "good mod" was done only because one day you decided it was a good idea.

You cannot give any fact based specifications about the two systems.

So that simply means you made your decision with ABSOLUTELY NO INFO. In other words, you made an UNEDUCATED guess.

You then report your successes as verified buy your "Butt Dyno".
Somehow I feel safe in saying I doubt you can provide any sort of lab tested certification letter for the accuracy of your butt.

And again, What affect did it have on performance?
Real tested HP gain?
Real, track tested improvement in Quarter Mile times?
Real, track tested lap time improvement on a road course?

You know what the problem is with the JBO


Yes, its uninformed, unexperienced people doing unnecessary and useless modifications to their vehicles and claiming huge unsupported gains from them.
Then, they pass themselves off as an "expert" and convince others with less experience to follow their lead until their level of disappointment in the real results cause them to abandon their hope for their car and move on to other things.

I am not going to say that the mod is bad or god.

In all honesty it may be a good mod but i personally would like to see some numbers on this modification. I remember that many people have said the GM ignition system if pretty good and no need to upgrade. I am not bashing but before i do it i would like to know how well the mod worked.
Also how old is your car, have you changed the coil pack on your car, or any ignition items before this as part of maintainence. I know i just change my coil pack on my car and it is running much better now.

Just unanswered question. I am not an expert but i just want more information. If someone else does it and give more info or gains then more people would jump all over it.

Anyone that knows the name Misnblu knows that I don't post bull@!#$.
Most of you don't know me as I've not posted in quite some time. Look at the sig Protomec and maybe you'll understand.
I've been working on cars, modifying, restoring them longer than you've been on this planet and know a little something about cars, old, new, so I would'nt laugh so hard, Protomec.

On the issue of gains for this mod, none that I could see and if the article were read, would know exactly why.
Re: The downpipe that was done by a local muffler shop made the bend so small that it's smaller than factory at 1-7/8 inch inner diameter. This is called restriction and anything you do to pass more air through this restriction will limit overall hp, period.
That is why I've been stuck at the 15.6 mark for so long and wondered why everything I've done hasn't yielded any gains.
Yes, I know what I'm doing with the mods, how to tune, etc. I just don't have the money to get the exhaust changed to what I want as I have a Paintball team that I sponsor and solely pay for out of my pocket. Protomec or whatever, when passions change from cars to paintball, you too would spend every penny to take your team to the top and we're doing just that.
I've spent over 12,000 dollars into the team in the last 17 months and just think what that would have done to the car if it was spent on it instead, so you see where my money and passions go.

The only proof I have with gains is the last time I went to the track, posted three 15.6's in a row where I usually post high 15.7's and low 15.8's before the ignition mod.
Believe me, with the exhaust setup like it should, should be running low 15's with the setup and mods that I have.
I don't care what ppl believe on the.org, they've not done the mod, much less even read it word for word.

It just sickens me that when I first started on the JBO, I was hungry to learn all about the J-body and this was the place to go for information and gain information I did. Now it's just a bunch of dumbasses that have the money to just put parts on or have someone put them on and then brag because they have this mod and that mod. Woopeeee.
Make your own intake setup Protomec from scratch. Do your own ignition modification from scratch and don't use others information, use your head for the ideas of what to do. I doubt you could do that.

I'm working on the downpipe issues and will soon remedy all of the naysaying this place seems to be with times that will be proven with timeslips, as I always have proven with when there was doubt. I've always been truthful and never had a question about my integrity, character, be it here at home or on the net.
Btw Protomec or whatever, how's that 15.8 you're so proud of. lol
Anyone can use nitrous to make their cars go fast but do it in a n/a mode. Oh, you don't know how, that's understandable.
You suck man.

I hope you do and wish you find what I already know.
Thanks for the backup too.
Too bad I don't have a nearby dyno like Protomec and have the opportunity to delve into all of the aspects of posting every little nuance of information he so seems to need to prove things.

My car has 150,000 miles on it, is strong as ever and prior to doing the ignition mod, still ran 15.7's and 15.8's consistently. Track time is where I test and tune.
BTW, for those wondering when I did the 15.631 which is the best time I've done, is when I had the car completely gutted with no carpet, no passenger seat, no rear seats and was done over two years ago.
I change my oil with synthetic 5w30 Mobil1, change plugs every time I change oil, had the RKSPort booties with springs on the car prior to the conversion.
My last runs were 15.65, 15.67, and 15.69 at the track with just a passenger seat, no rear seat and full oem carpet in the car. I have time slips to prove it and witnesses from the car club as proof too.
I don't bull@!#$ when it comes to cars.

Thanks for the inquiery and hope this answers some questions.

Sounds good. I am not just going to take every thing just as it is. I am not one to just put a mod on just because. I usually wait till a bunch of people can verify it before i do it. If i see more postive feed back then i may try it. Then this kind make me wonder because other have commented saying the ignition systems we have are pretty good and really need no modification.
I have been on the JBO for 6 years as well even on the old Z24.com

If you were only 17, I would have expected and even accepted your lack of knowledge. At 45 years old, I think your learning disabled.
And besides, being a manager of an electronics store definitely means you have much more experience at this then me. I've only been wasting my time working (as in getting paid to) as a racing mechanic for the last 18 years. Time to stop wasting my time doing this.... got any openings at your place? I think I can accept making poverty level wages for a while just so I can go back to my career and school all these other losers I work with everyday who haven't had your background to REALLY UNDERSTAND automobiles.
Oh yeah, I'm truly laughing harder than ever now.

As for bragging rights about 1/4mile times, 15.6???? are you thinking this is Blackjack or something?

Back onto topic...
I thought about writing a page and a half about how the 2.2/2200 ignition system and the IDI system are both truly the same. The only physical difference is how they are layed out and how the components look because of it. But since everyone's supposed to just trust you about your claims, I decided they can just trust mine. I mean, after all, they can just ask me at IRP in July if they want to have it explained.

Hmmm... I don't agree completely.

The IDI and 2200 DIS system are functionally the same, not physically. In my experience (lotsa years fixing cars for a living) IDI systems are more likely to develop shorts in the secondary path than the external coils used on other engines. I've always believed this was caused by (1) differences in temperature between the external coil/ plug wires combo and the cylinder head mounted coil/ plug boot system, and (2) the amount of insulation between the secondary paths and ground. Granted, I have to say that both systems are reliable imo, and that I've never seen enough of a problem to need to convert from IDI type internal to DIS type external coils, but there may be some spark energy and a little bit more reliability to be gained by moving the coils and module away from engine heat. If I were making this conversion I definitely wouldn't mount them in the same place as the system I was removing.

With either DIS or IDI I would probably start an "ignition mods" project with a thorough check of the stock system and replacement of any suspect parts with OE quality or better equipment. I've seen cars with 200k miles on 'em and all original IDI parts except plugs, and they run fine. And I've seen the IDI system used on engines making a helluva lot more power than any 4 cylinder I've built, and they still work well enough to keep the engine builder happy. Besides, the "hot" swap is coil on plug, not waste spark.

I'm looking at doing the mod myself this year so I thought I would bring this back from the dead. Anyone else accomplish this mod? How hard was the re-wiring job? I'm trying to follow all the instructions and diagrams and I get lost a few ways here and there. Anyone have another write up or some other diagrams that they used?

Thanks for the help JBO.

I'm glad you searched, but you obviously didn't click on the best topic choice.

This has been done a bunch of times by a lot of people, some people are also using the Neon coil assembly now too the thread for that is still on the first page in this section too.

i have this mod done as well on my quad....did it give me 10-20hp? ha, i doubt it cus my butt dyno works really well ..did it help my start up?ummm it might take a COUPLE less times to turn over now before it starts...did it actually help my upper end spark or powerband at all?? dont know, my butt didnt actually feel much difference ..BUT i am getting another dyno this week..only thing ive added is the coil conversion......and the ttr upper mount ...so lets see if my first run pulls anymore than my last..hows that

I remember this thread and am still saddened by it's content.
No hard feelings toward anyone here.
I think that enough people have done this to prove some value to the modification.
Thanks to all that have tried this and approved.
I'm still running on the same original setup and haven't had one glitch ever.
Good luck all.

dont get me wrong..i havent had any issues with it...and if it lasts longer than my crappy stock coils that kept going out ill be happy with it...but as for proving performance gains its going to have to be done on a dyno....so like i said im going again this week to do some tuning..the only hardware ive added since last time is the coil conversion and the ttr upper..so before i start tuning my first run should show the gains if any ...ill let you guys know later this week
