I just put in an e6k in my FD and everything was running fine for about 2 weeks and now at of no where the car just died. I towed it home and it turned out my plugs were fouled. So i put in a fresh set and the car is still breaking up. It seems no matter what i do it just keeps breaking up.. And the program that was in there wasn't that bad. I mean i don't think it was that rich. Anyhow im running premix at about 1 oz per gallon. Could that have anything to do with it?

It also seems to be fouling out the leading plugs. I put another new set it and it's the same ****.

What could it be?

 

Sounds like your running very rich. I had problems with my setup running too rich and sputtering/breaking up. You just want to make sure its not breaking up due to lean condition instead of rich conditions. What kind of ignition setup do you have? What are your air/fuel numbers when you datalog?

 

Also what turbo and injector sizes are you using? If its anything close to mine you could send me a map and I could look at it for you to compare.

 

the ignition is stock... Im using a wideband and im getting readings of 12.5~13.0 while cruzing and it still sputters. Whats wierd is that it was running fine with the same problem for a while. Now it just won't run... Today i tried using the base map from ricemobiles site. And it's doing the same thing... Could something else be wrong?

 

So the problem is occuring when your just cruising, how about wot? Have you tried to pull fuel out to see how it reacts while your cruising?

 

Stock injectors, Stock twins. For now.

I have 160lb injectors ready as well as a complete fuel system. Just working the bugs out first. If i go wot i can get it to go.. It seems to really happen mostly at cruzin speeds... What concerns me is that i have to take alot of fuel out for it to be at the right mixture.. Why would it be so bad.. It was running fine like this for 2 weeks and now nothing. I'll send you maps so you could take a look.. PM your email..

 

I get the same problem when I feather the throttle. The ecu doesn't know when you're on throttle or just trying to keep it steady.

 

Check to see if you leading coil is dead. If you're running too much coil charge time on stock coil, you'll blow them up. try to keep it less than 3.5ms if possible unless you have aftermarket coils.

 

Pluto, I believe your right. Because no matter how i tune it rich or lean it still breaks up... I guess it's true what they say about 3rd gen ignition quiting. I guess it's also explains why i keep fouling out leading plugs.

I have a set of 2nd gen coils and ignitor i will be replacing them tomorrow and i will let you know.

Thanks

 

How do you test them?

 

I believe you check the resistance across the terminals.
I will be testing mine shortly.

 

test it with what tool?

 

use a meter and test the resistance across the terminals and it should read less then 1 ohm. And you also check the resistance across the spark plug post and that should be between 9k and 16k ohms. (leading coil)

I tested mine and it seems fine. I also checked the resistance across my spark plug wires.

My MSD wires were between 35 ohms and 50 ohms
They were the owns currently on the car.

My old Magnacores were between 1.35k and 2.3k ohms. Why such a big difference between the two.


So I still can't figure out why my car is breaking up.
Has anyone experienced the same thing?

 

I'm going through the same thing with mine so I'm going to try throwin a couple msd 6a's on mine and see what it does.

 

Resource are you running e6k as well?.

I don't know whats wrong with my FD. It's starting to annoy me. Could it be the ignitor? If the ignitor goes bad will it still produce spark? or will it be completely dead? My car starts up fine. But it doesn't rev up cleanly or if it does, if you take it for a spin it will sputter and break up as soon as there's load.

I believe something is wrong with my ignition system but i can't seem to figure it out...

 

I have the power fc.

Mine has always broken up,the only way I got it to quit was to buy 120 dollar plugs (NGK11) and that cleared up the nasty breaking up issue for about 3 weeks then it went back to its same old shitty self again.......

I would figure if the ignitor was bad then the car wouldnt even run.not sure though.......

 

Yeah thats what i figured about the ignitor too, it's either works or it don't. If its bad the car won't start.

Anyhow there has to be something causing our cars to run like ****. My car before the E6k had a little misfire in 3rd and 4th gear at high rpm, like 6500~7000.

Then after the e6k install, it ran mint for about two weeks and now it's breaking up all over.

This is why im leaning towards something with my ignition. But when i test the coils they check out fine. Wires seem ok too.

Maybe it's my fuel pump? Im gonna rip that **** out and put it an aeromotive pump and big lines. I can't take it anymore.

 

You dont think it's your ignition?

It shouldnt be your fuel pump unless your getting high boost and your fuel pressure is dropping.

 

No. I still believe it's ignition. It's got to be.
I just want to elimate everything possible besides i already have the pump, filters, and regulator just sitting around.

Im thinking about trying different plugs. NGK 5671A-10 Maybe this will help?

 

I think if you put those nhk 11's in there you will see a tremendous improvement!

 

Im gonna try that today and i will let you know...
When are you gonna put in those MSD 6a's?

Im wondering if i should just go ahead and order some.

 

Not sure when I will put them in,probably next weekend sometime.

 

I have an extra ignitor if you need it
