I'd like to get one of these boards or even prebuilt ones, are there any left? I'll be happy to chip in... I'm already running the 2ndgen coil, so this sounds like a great upgrade, thanks guys for putting this together...

I know it can be hard to follow. With the assembled kit, all you need is a 2nd gen leading coil. I even try to supply the needed connectors. mJust need to track down a source for the 1st gen ignitor connector. This plugs into the 1st gen leading ignitor. You then connect power and ground. Then just hook the output to the 2nd gen leading coil (you also have to hook up power to the 2nd gen coil of course). It is pretty straight forward. There is another post called something like "2GCDFIS with transistor trick installed" by lovintha7. You should check it out. Not so much technical stuff. It focuses more on the installation and results.

Zyrano: I'll add you to the list. I will make a few extras becuase I know some more people will probably pop up wanting one especially after more people try the circuit out.

This is so close I'm getting nrevous. Kent, when do you figure you'll get these ready to go? I've got an extra set of coils now so I believe I've got all the parts.

 

Real soon. Actually, you are basically at the top of the list because you stated that you wanted one of these for sure the earliest. How about I assemble one of these boards for you? I'll see if I can get all the parts locally. I'll figure out something on the ignitor plug. I can try nto hit a wrecking yard and grab a couple for now.

I got these 4 boards etched. They look pretty good. I'll post some pics later. I found the the box that we'll need to use will be bigger than those I used before. The extra space is needed for the auto switching circuit. Actually the old box is big enough physically, but they put posts on the inside to screw on the lid. These posts make the 3" long box only hold a board 2.25". RadioShack does sell a box that is 4"x2"X1" (same as the old box, just 1" longer). I think this will be the one we'll have to use.

Here is a pic of the etched boards :

 

Very nice looking boards. I think I am going to jump in on this as well.

 

Looks nice Kent. I switched back to variable p/w last night while cruising around town, and it sure does make a difference in the low rpm power/torque. I miss that high rpm surge though. Wonder if I should have mounted the box inside so I could flip it back and forth whenever I feel like it.

Hopefully you'll be able to get enough of these circuits together before you leave. Also, I wonder if there's anybody out there skilled enough to pick up the torch until you return.

 

Hiya Kent! How do I get on the list to purchase your board? Please let me know...

 

Me too, add me to the list for a board!

 

I'll add you guys to the list. The list is getting pretty big. That is a good thing. I think that you guys will enjoy this mod.

Kentetsu: You could mount in the car. I don't think the ignitor wires would reach, though, so you would have to extend them. I haven't had a chance to really check out the fixed PW mode. If it is that noticable, the new circuit should be really nice with the auto switching and all.

It would be good if someone could take over. The other thing I was thinking is that I could make several extra boards. I could then send them to someone I trust and then they could distribute them while I am gone. I will probably be back to visit next June and could crank out another batch then as well.

I will see if I can drill these boards today. It is hard to find a chuck that will hold these tiny bits, though. Also, the next batch I will leave in the etchant longer. There are a couple spots on these boards that I will have to clean up by hand. The toner bonded really well and did a very good job protecting the areas that weren't supposed to be etched. I now know that I don't really have to worry about over etching with this process.

Kent

 

I'm good with soldering on boards, though I have no idea how to etch them.

 

Kent,

I would be willing to help you in any way I can... Anxious to get one of these in my hands.

Toxic_d

 

Thanks for the offer. Did you want to get one of these blank boards? Or did you want to get an assembled unit?

Any help tracking down those ignitor connectors would be helpful. I have tried a bunch of places, but can't seem to find them.

Kent

 

you can prob count me in too thanks

 

I can't wait to see how this turns out compared to the MSD 6A I'm running now. I hope you've still got me on the list.

I'm not much of an EE geek, but if you need any IT type stuff, let me know -- I'll be more than happy to help.

--matt

 

Yep, still got you on there, speck. dj55b: I'll add you on as well. Thanks for all the support, guys.

 

Thata a positive on the board and if you want to contact CAG8or on the mazspeed forum about working with me... go for it I helped to get the A-pillar dual guage pod moving and helped him get rid of his extras.

You guys decided to use the auto switching idea afterall eh? Well, I officially feel like I contributed something to the project now! The hard part might be trying to figure out the exact right RPM to switch at. Maybe use an adjustable resistor or something to "tune" the RPM at which it switches for each individual car?

~T.J.

 

T.J.: Yep, we used your idea. Implementing it actually tuned out to be simple. Instead of using a microswitch or some sort of RPM switch, this design with switch based on whatever mode gives the longest PW (coil charging time). This way the variable mode gets used in the low end and whenever the variable mode drops below 2ms, the fixed pulse mode then will kick in. This way there is no adjusting. The outputs are still there for the fixed PW and the variable PW modes as well in case someone likes a single mode better.

toxic_d: Thanks for offering to help out. We can maybe set something up. Either I can make extra boards and you can distribute or I can teach you how to the boards and such yourself.

 

What ever you decide is cool with me...

 

i did the mod tonite just the simple 1 and wow.com the butt dyno is right my idle got better and man it pulls all the way threw the rpms. thanks gsl-se addict for thinking this up and maybe there is more in the trialing i hope

 

Cool. Keep us up-to-date on how you like it. Also check the timing. It was found that this setup tends to retard the timing a bit. Once you reset it, you may have even more get up and go.

 

oh heck yeah i will check it. and btw why does it play with the timing

 

I hate to say I told you so, but...well, actually I guess I don't hate to say it!

But yeah, if you didn't check the timing yet then you'll probably unleash a few more horses yet. Welcome aboard.

 

Sounds good! With all the know-how you all have together, Im sure you wouldve come up with the idea eventually, so Im not gonna take all the credit for it Im just glad that you guys are doing something that helps out our cars again. Good technical stuff in the forums again is nice. If I run a 12A in my car again, Im definatly going with this setup vs the DLIDFIS I had last time. I liked that a lot, maybe Ill love this, it sounds like everyone else does!
