ok, just got back from driving it, all i can say is wow, best 50 bux ever (coil + trick) and i haven't even adjust the timing yet... the car is smooth, doesn't choke at all until 1500 rpm (i have a aluminum flywheel, so it didn't like anything lower that 2k rpm decel)... more power up high and midrange... i sure hope somebody can take this project over, because this is a must have for all first gens!

oh yeah, the exhaust smells cleaner too!

kgray

so all are gone? any plans of another batch or something?...guess i was a few days late

If anyone can and has the desire to make these that would be great or a guide tomake them ourselves.

Just got home from work and the local bone yard.Scored a 2nd gen coil and 3 J-109 ignighters for $25 Installation of the box was very simple. Only drove home from the shop but noticed a much smoother idle and slightly changed exhaust note. Fun tommorow will tell. Also found 2 disc brake rearends at the yard if anyone is interested.

Kentetsu

I told you guys this rocked! Glad to hear its working out for you guys as well as it has for me. I totally agree, best 50 bucks ever spent on my car!

speckamp

does anyone have pictures of the 2gen coil mounted in a car w/ ac? I'm coming up a bit short in finding a spot to wedge that beast.

thanks,

I have yet to find a good spot. The coil just doesn't fit on the wheel well. I am tempted to seperate it into 2 parts so that I can mount it there though.

Kentetsu

I don't have my A/C installed anymore, but here is where I mounted mine if it will help any.

doh... missed my chance I suppose..

There may be an opportunity to purchase some of the old style (with switch between fixed or variable p/w) as members upgrade to the latest model. I have one extra now, but might be keeping it in case I ever pick up another 7. This model still works well, in either mode, with the variable giving nice idle and low rpm cruising performance and the fixed giving a weaker idle but more power at higher rpms. I always used mine in the fixed mode, but I believe most others used the variable. Whichever model you might end up with, I would highly recommend it.

I have the same problem. Kentetsus' setup only works because his A/C is not there, but it does look nice :-) I want to keep my A/C so I'll be mounting mine on the strut.

I'm planning on mounting 2nd gen coil seperated from the igniter backing plate. If you mount the coil separated from the igniter it will fit on the inboard side of the strut. We're not using the igniter anyway, except for that resistor and I should be able to pick one up at the 'shack. I'm fabbing up a sheet metal mount that hangs off of the two inboard strut bolts and around off of the back side of the strut tower where there's some existing threaded holes left for anchoring it. The coil will be on the inboard side of the strut and the j109 will be on the back side of the strut. I plan on making the whole thing an assemply that I can easily bolt in when its ready and just add some jumpers to the existing ignition to set it all up. I'll put the trick on the back side of the strut as well when I get to that point.

My goal is to make it very easy to switch between stock ignition and the new setup so I can have redudancy in case things fail. Plus I don't want to cut any 2nd gen coil wires or stock ignition wires if I can help it.

Kentetsu

You mentioned that "we are not using the ignitor anyway, except for that resistor". If I'm hearing you correctly, then you are mistaken. The 1st gen ignitor sends the signal to the 2nd gen ignitor, which then triggers the coils. You do need the 2nd gen ignitor for this to work.

Thats if I'm using the trick, right? If I just do 2GDFIS then I don't use the 2G ingitor at all.

Thanks for pointing it out. I will still have room on the back side of my mounting to put the 2G ignitor on there with the trick. Maybe I'll rework it so that the full coil unit with the ignitor sits on the back of the strut tower and the extra j109 sits on the inboard side.

Zyrano

yup, just for the trick, but the trick works way better then just the 2gcdfis.

DJAngelicon

Man hearing reading all of this about ya setup can not wait for my board to get here so I can start mine.

t_g_farrell

We'll see, I plan on staging this first as the simple 2GDFIS and then move to the trick once its all stable. Maybe even get a dyno on it, but don't hold your breath on me posting the results. It could be months before I get that far and then I'll have to wait until warm, dry weather in PA. Thanks for clearing that up for me.

Xavier8

honestly, it is no easier to setup it up for 2nd gen ignition with just the 1st gen ignitor then it is with the trick and both ignitors. Its a few extra wires and a tiny little box. If you have a second gen coil intact with ignitor not cut off anyway, then it would take you less time to set up the whole thing than it took for me to just swap to the trick. The hardest part was reinstalling the ignitor. No need at ALL to wait, it will not save you time and you'll have months without the extra power and smooth idle.
I can tell you aren't 23 like me, you mature rx7 drivers like to plan more than you like to drive. If you wait, you are just doing the job twice, and you don't need an ignition stabilization period my friend. Take our advice. Good luck.

Zyrano

yeah, i'm with xavier8, if you have the trick already, just install it, I ended up getting a second coil/ignitor from the junkyard so i don't have to try to get the ignitor back on the old 2nd gen coil.

I don't have the trick yet, I'll probably just build it myself based on the the info gsl-addict posted here earlier. Its a pretty easy circuit and he made it even easier by showing the board layout. Until I do that I want to start running with the 2G coil just to at least get the wasted spark ignition benefits. I'll take my time, as usual, and make sure its done to my satisfaction. Also, one of my goals is to be able to swicth back and forth easily so can measure any differences. I want to compare stock, 2GDFIS, and the trick so we can determine what the gains are and where they happen at. I don't trust butt dynos, or dynos that much really. I prefer to use a stop watch and some cones :-)

Zyrano

i don't think you'll see much dyno/butt/track improvement, but the car is so much more civilized, smooth, great response...

Xavier8

my car has a definite increase in upper rpm power, may be the ignition helping the streetport. From my understanding of everything said by addict, the stock 1st gen ignitor cut pulse width to very short at high rpm, much shorter than necessary to avoid overlap, so the longer fixed width pulse of the trick might be providing a more complete burn, and thus, higher power. One one or the other, I am happy with it, I redid my ignition wire loom today to clean up the engine bay and incorporate the trick box into the system.

Zyrano

hey guys, i'm trying to figure out the interests in this, I've been browsing a bit today, and it looks like we can get these boards manufactured for under 10 bux a piece. Note that this doesn't include any components, so somebody's got to built it, I'm not looking to make money on this, just figure that it's one way to get more people to experience the 'trick' i'm not very good at soldering, but maybe i can practice and get this going? what kinda interest would there be?

Alvin

grayhare54kc

id be in for one or two!
anyt 1 gen owner should have it.

toxic_d

Contact Kent before moving forward with such a project... If you were to build one for yourself I doubt he would mind but if you start selling them then thats a whole other situation.

Toxic_d

Zyrano

I know, i have every intention to do that, like it said, i'm not looking to make money or anything, but i'd definitly talk to ken first! or if anyone else ones to do it too, i just found online pcb manufacturing and it looks if the quantity is there, a board can be as cheap as 8-10 dollars... it's just my two cents
