Guess I slept through some of the postings, I thought Kents departure was going to be next week. Well, Bon-voyage Kent. Good luck on your new endaevors in France. Congratulations on your acheivements in life thus far, you seem to have what it takes to "Git Er Dunn". The ability to work in a team and pool resources
(mental and physical) goes a long way in determining how sucessful people will be in life.
I admire the support and team work displayed in this project by everyone really; but especially Jeff, Kent and kenteau, it makes me feel like this is a good group to be affiliated with.
Anyway, enough of the acolades.
I need one of these. How can I get my hands on one ?? Ill even consider an older "switched" version !!

Thanks Xavier8,
I sure envy you right now. You got the second of the autoswitching model correct ? SWEEEET !!!
I hope you enjoy the gains.
PS... I am an avid NGK wire advocate though. Remember rotaries don't like the higher resistance that often exists in other wires. But if it cant reach on stock wires ( depending on how things are mounted in your triumph) then do what you have to.
Thanks for chatting with the "Rook"

Ok here is my setup after I installed the new wires and did a test run which I can not believe where this performance came out. I swear I had the car hop in 3rd and my girlfriend got scare for a sec. She even said the performance, idle and sound is lot better. She is not a car person like that she’s been learning along with me and man if she can tell. Then something most be good in this setup and that my friend is the 2GCDFIS mod.

Totally Awesome!!!

Here is a picture of my setup, I Took it fast before it started to rain.

Looks awesome latin. Its amazing that my tiny car has more room to mount everything, mine doesn't look near as packed. I also redid my whole front wiring harness to incorporate the trick and 2nd gen coil, so she looks very professional. Did you go from completely stock ignition to 2nd gen with TT Latin? That must have been a giant change considering just adding the TT to my setup madce such a difference. I also gained better idle by reworking my ignition power thru a nice thick gage wire.
Sweet_Revvin: Where did you get your wires, and at what cost? I know that nopi can get me some sort of NGK for less than 20, but I haven't checked them out. I hope you have some luck getting a setup, it is so awesome.

Give everyone a better idea. My engine bay looks dirty, anybody have any tricks on removing engine paint so I could redo it?

A couple of really nice looking installs guys. Glad to hear that everybody seems to be getting the same astounding results as I did. I'm amazed at the power that this unlocked for me. Got to find a new source so we can get more people hooked up though.

Hey Xavier8, Nice little car you got there amazing. Your setup looks awsome as well and looks like you got alot of room in there. As for me, my car is stock completely stock so yea this is the first real mod to this car beside removing the flooper from the air box. Beside that, I still need to remove emission stuff, try to see if can start saving for header, presilencer and muffler but it all if I don't end up upgrading to a 13BTII or 13B Rew in the near future. For now small mods would be great.

Hey Kentetsu, Yea thanks for providing your pictures and information about the installation. From your information, kents, and jeff I got this to work in one shot. I know I have asked lots of question here and to ya but the reason I ask is to learn from one shot so I don't have to ask later on again. I feel comtable rewiring my engine now and re-installing the setup if I need to with out the need of looking at the information or asking anyone unless we do a new upgrade or modification.

I am still debating if I should buy a timing gun or not to check my timing.

N/M. Doesn't work too well with a turbo setup eh? Glad you didn't mess anything up too badly, and its not like you won't be able to sell it to someone else...

Sorry to hear that FB II. Which it did work to the point you can notice some good improvements. I have my car was crapping around two months already. I did a fresh installed of all this and it helped me alot. I am still thinking of getting the rotor replace new, getting a timing gun to test my timing. Hopefully buying a nickki to get it tune up and tweak so I can replace the one in the motor for better performance. There is so many things I want to do, little time and little money for them.

Good luck though which whatever setup you end up doing.

Looking great, guys. Made it to Avignon. Paris was a lot of fun. SUVs are extremely rare over here. Lots of French cars (of course), some BMW, Merecdes, and VW. Even seen a couple Ferraris, an Astron Martin Vanquish, and a couple Miatas. No 7s, though.

Let me know if you would be interested in a circuit (assembled or not). I can complile a list so we can see how many to build.

For those who don't want to wait, you can build the original circuit (just two transistors and a couple resistors) pretty easily. This setup works well and could get you by until more auto-switching boards are made.

FBII: What issue did you have wuth the 2GCDFIS? I know you don't have the TT (atleast not directly from me). TurboSE had one on his turbo SE and had good results. Just wondering what the issue may be.

Kent

Sweet_revvin_seven, welcome to the forum! Heh, you're a new guy and you're already using the new acronym: 2GCDFISw/TT.

TheLatinHeat, that's awesome that you got it all done in one shot. As Kent said, the leading timing retards slightly, so a timing light could help you get it back to normal and also you could play around with the trailing split. I think 12As like a split of 8°. Others will know for sure. Otherwise, it's ok to drive on it as-is for now.

Kent, I bet it's so nice not seeing SUVs everywhere you look. Have fun over there.

How do I test the 2nd gen coil? I think I got a bum coil.

Thanks Latin heat.. Your setup looks nice too. You did'nt use the spade plugs huh? or is that hte way they'll all go to the distributor ?

Im lovvin the Triumph Xavier. Sweet ride!! Lots of room to work too. Real neat.
I usually just order from NGK.com. They list it for under $17 bucks, but I think Napa will get it for you next day for $21.++.

Thanks Jeff. I know the importance of correct "Jargon". (Information Technology) .... I read the "Black box" exchange ... I agree. If something is being pioneered here, lets keep it unique. Congrats by the way... Idea to reality! Cool

Kent... I dont know if you will have the resources to continue producing the autoswitching units until you get settled in depending on how the transition goes. (I'm figuring that probably was why you didnt comit to it.) But if you have a list, definitely PUT ME ON !!

In the meantime, if anyone has a "TT" type1 they want to part with... Im your mann.

Kevin..

Yea me too, I'm definitely wanting one of these, preferrably one of the new models. So lets scrounge up some parts list and get this going again! I can solder all day long.

Hey Sweet_revvin_seven, I didn't use the spade plug because that is the way the setup should be. Right no the bay is messy with those wires I will take some time to get ready in order and might do some engine bay work when I get the chance.

Hey Jeff20B, Thanks, I will get a gun anyways sometime soon but for now is runing great.

Kent

really? hmmmm this is weird. my issue is that it seems to be igniting like crazy during the exhaust stroke. under boost at WOT it is throwing 6ft flames and hesitating bad. killing the boost and probably hurting my motor. it's not detonation or pinging, but just massive backfires. everything else works great. crank up, idle, cruising, half throttle low boost, but wot is just beat up. nothing changed in my setup... all i did was install this mod and that's it. would spark plugs make a big deal with this? i'm running b9es ngk's gapped to .030. i have a set of stock TII trailing bur9eq's i could try.

Well, I wouldn't be able to assemble them. I don't have any of my equipment here. The boards themself can be professionally made (~$10 or so each for a quantity of 30). We could have the boards made in the US and someone could be in charge of distributing them. There are also several guys on here that said they can solder, so they may be able to help assemble boards for those who don't want to. The key may be putting them in boxes, drilling the holes in the boxes and doing the wiring. This next batch may be more of a DIY sort of thing than the last batch. I would do them if I could, but the cost of everything would just be too high for it to work.

2wankel: I believe the resistance of the 2nd gen coil is suppose to be less than 1 ohm between the + and - terminal. It could be the ignitor, too. Do your LEDs blink when cranking? You can also try unplugging the first gen ignitor and taping the yellow wire against ground. The green should go out and the red should light up. The blue output wire should go to ~4.4V. This will tell you if the circuit is working. Make sure the 2nd gen coil body is grounded well and that the tan wire has 12v. Good luck.

FBII: He was using an EFI setup, so that may make a difference. He did say he ran like a 12.4 with the setup. He later said that he ignition problems but thought maybe his pulley was on wrong or something. Maybe you need different jets with this setup. You could try the other plugs. I think TurboSE was running 2nd gen leading plugs in his. Also, did you verify timing after changing to the 2GCDFIS?

Kent

Definitely have to adjust the timing. Wishing I had thought to ask you that last night. The ignition is for some reason retarded (about 8* on mine) after the installation of the TT. The late spark would not allow for complete combustion before it was exhausted (hence the flames). You think?

So Kentetsu, that means I would have to buy that timing gun tomorrw then. Most places I have looked have them for like $32-35 dollars. Is that the cheapest they run now? I want them with the clip that clips into the first sparkplug wire instead of placing them directly to the sparkplug.

***NOTE*** FB II did not have the transistor trick when he tested his turbo setup and the 2nd gen coil. And his issue was fixed by adjusting the trailing timing. (taken from update on other post). Just wanted to make this clear.

Thelatinheat- Timing will need adjustment, but you might be able to do it by ear if you need to. Otherwise, 30 bucks is probably about right for the inductive type light.
