I just installed the 2gcdfis and it starts right up and idles alittle low like at the first little line on the tach.but when i rev it up theres alittle hesatation in the low rpms like less then a second but after that it shoots up is this normal?and it still backfires just a little less. please any info will help thanks

sounds like you need to change your plugs and wires

Did it also do this on the stock ignition? Do you have the resistor wired in the circuit (in the back on the 2nd gen coil)?

Where in Oregon are you? Maybe we could meet up sometime.

im in clackamas and i did wire the resister i think

dumpedfb82

what wire is the resister wire and yes i have a stock ignition its a 82gsl is the resister wire the one that u splice together inside the coil or the - one on top

dumpedfb82

anyone help please

Here you go. It should look something like this.

yes i did i splinted those wires together then i disconected the + side on top of the coil i know all my wiring is right how would the resister affect the hesatation at low rpms

dumpedfb82

or at lease i think soo???

Besides splicing that wire, all you should need to do is connect switched 12v power to the + terminal (can use the same source as the first gen coils, black wire/yellow stripe). The - terminal of the 2nd gen coil should connect to the yellow wire with green stripe (the one that connected to the 1st gen leading coil, - terminal). Having the resistor shouldn't cause hesitation. You should use it or your ignitor may burn out. Did you have this hesitation with the stock wiring? Are you sure that your spark plug wires are all going to the right spot?

how do you connect switched 12v power to the + ??????explain

Same power supply as the stock coils. What I mean by switched is that it only has power when the key is on. How is yours wired? What did you connect to the coil + and what did you connect to the coil - ?

dumpedfb82

wait so I should connect the top + side of the 2ndgen coil that it tells you to take off the original wire and make a new wire too connect to the - side of the stock leading coil

dumpedfb82

i just have nothin connected to the + side of the 2nd gen coil i mean like the top of it where u can see the + sign where the plastic cover with l1 and l2 goes over

dumpedfb82

I did conect the spliced wire to the + side on the stock coil and the - side on the 2nd gen coil under the l1 and l2 cover ontop to the - side on the stock coil

I am not sure what you mean. Do you have a pic of how you have it wired up? If the coil looks like the one in the pic, you need

- power (can be from the stock coil +) connect to the 2nd gen +

- signal (- terminal) This should connect to the YG (yellow w/ green stripe) wire of the stock ignition. Connect this YG wire to the black wire coming out of the top of the 2nd gen coil. This black wire goes though the resistor and out to the coil - terminal.

Don't have the YG wire connected to both the stock coil (the one you aren't going to be using) and the 2nd gen coil. If you connect them this way, the ignitor is going to have to fire both coils together. This will place a large load on it and may burn it out.

dumpedfb82

on the power the stock coil + is the fat wire right and the 2nd gen + is the wire that you splice together on the inside then the signal is the yellow green wire connected to the - side of the 2nd gen coil on top underneath the l1 l2 cover

dumpedfb82

i took out the coil that i wasnt using

Well, follow this thread. It'll tell you how to do it.

https://www.rx7club.com/1st-gen-archive-71/electrical-easy-2nd-gen-direct-fire-install-20-minutes-398818/

So you have power to the black wire and then connected the black wire to the coil + and then connected the YG wire to the coil -, correct?

That should work. I was saying the same as this thread. Keep the black wire going to the coil - and connected the YG wire to the black wire (where it comes out of the top of the coil). Then connect power directly to the coil + (under the L1 L2 cover). Hope this helps. I have to go now. If you can show some pics or something I can tell you if it is right or not. Then we can go on to figuring out what is causing the hesitation.

wheres the resister??????im hella confused

dumpedfb82

u mean the ballest resister

Kentetsu

Yes he means the ballast resistor. It should be in the housing of the gen 2 coil pack (if I remember right).

Take a look at this thread if you like. It has some pics of my engine bay, and you can see some of the wiring for the coilpack. You can also see how your distributor should look when your done (once you have relocated the trailing plug wires and coil (high tension) wires to where the leading used to be)...

https://www.rx7club.com//showthread.php?t=414686

The fat red wire that you see exiting the coil pack is my positive, which hooks up right to the old coil's positive wire. My negative heads the oposite direction and runs to a bolt on the body.

Thinking about this though, I believe I will redo that and run it straight to the - post on the battery. You don't want to take chances with the grounding of your ignition. I should have considered this when I installed it. Oh well...

Hope this helps some. If not, the day shift will be in soon....

dumpedfb82

where does this wire go??????

Kentetsu

Man, its been over a year since I did this mod, but I believe that is your ground wire. You can either run it to a bolt on the strut tower or better yet, hook it straight to your negative battery post...

The other wire that comes out (the one that is spliced together) goes to the old coil's postive wire...

Kentetsu

Best thing to do would be to follow these directions (written by MetalRock)... Just go through the steps and make sure you did everything just the way he says. These are the same directions that I followed, so I know that they work...


1. Get your 2nd gen coil with ignitor.
2. Cut off the electrical connector for the stock wiring.
3. Take the 4 screws off the back.
4. You will see on the left side, a large ignitor - cut all the wires off of it as close as you can to the ignitor. (you won't need it, anyway) Now, un-screw the 3 screws that hold it in. Discard the 2nd gen ignitor.
5. On the right hand side, you will see a balast resistor. There will be a black wire going to and from it. When you cut the wires, previously, you would have noticed that 2 black wires were soldered together on the ignitor. Splice those two wires together. (connecting the - side of the coil to the bottom of the resistor)
6. Disconnect the positive side of the coil. - 7mm nut (you will have to take the plastic cover with L1, L2 on it, off)
7. You're almost done!! Screw the cover back on the ignitor. Mount the assy- closer to the spark plugs, the better. (shorter wires=less resistance)
8. Disconnect the stock wiring from the stock Leading Coil. Connect the wire which was previously connected to the - side of the stock coil to the black wire that you would have left sticking out the top of the 2nd gen assy. Do the same for the positive side.
9. connect leading wires to the 2nd gen coil, then to the leading plugs. Move your trailing wires to the leading position on the dizzy.
10. Start, drive, park, pull yourself out of the back of your seat.

Jump up and down and say "hell, yeah, that thing is fast!!!"
