If only there was a forum wide ignore that no one would have to listen to it........ Okay maybe I shouldn't bait the trolls

 

I already tried it, YOU ARE STILL A MODERATOR

 

Maybe instead of just demoting you the can ban you as well? And even throw RSX in there too? That would be nice of them.

 

+1 lets keep this cleaned up.

 

Ok, stfu and get back on topic. No one likes it when half the thread is just stupid bickering.

 

03-rsxdsm has a lot of very useful information. I don't see why this argument is going on. Plus why don't you move it to another section, it is not pertaining to the original OP's thread at all. looks like someone needs to read harry potter bout power tripping lol

Edit: wow lol, his post got deleted for giving some advice on picking up spark plugs lol.

 

Clay if you're that interested in him, PM him and you guys can chat and scream till you're hearts content.

What do half these questions/posts have to do with spark plugs???

 

+1, please clean up and use MP for sold your different.

 

Well, it looks like the dyno testing will have to be put on hold for a little bit. I have no time during the week to do it and, as of yesterday, I do no have a license making it very difficult to get to a shop. As soon as I can get someone to drive me and my car I will do it, but I cannot make any guarantee when that will be.

 

So what is your guy's final verdic on these plugs after getting a chance to use them? From reading the forum thread (the technical parts) and the next to nothing results it kind of sounds like just another gimmick to me.

 

I think so far that "gimmick" is right. Based on their published data on the Toyota Corolla 1.8L engine, I think that any gains (if they exist) in a Fit, will be almost impossible to notice. I still intend to take a VERY hard mountain drive, but that won't show anything based upon performance so far.

We won't have the benefit of osborne's before and after dyno results due to his problems mentioned in his post above. I don't have time or patience to take the saqme drives at the same speeds over and over again to try to find a 2% improvement in fuel economy, and unless I see something obvious and positive in the next couple of weeks, I intend to send these things back. Remember, they last 1/2 as long as regular plugs that cost less than 1/4 the price.

Results so far: SAVE YOUR MONEY.

 

How did you piss off the cops or the court? Sorry to hear about your situation, and if it continues for very long, you might as well send your plugs back for a refund.

 

Sounds like good advice to steer clear. I have to say after reading the marketing info availaible I could feel myself getting sucked in

To be honest I think the ignition system in this car is already pretty good, I would doubt anything could boost it's performance drastically (and carry a reasonable price tag) enough to actually notice.

 

Well to make a long story short. I was driving a friend home who was too drunk to stand up. I had a couple of drinks, thought I was fine to drive, but the police officer thought otherwise. I had been cruising around on the hardship license, but that expired yesterday and I don't know how long it is going to be before this whole thing gets settled. I was hoping to dyno before and after the plugs were installed and I probably still will. And if don't and have to eat the $100 it won't be a big deal. THE MORAL OF THE STORY IS: Even two beers will get you locked up for DUI.

Now to get back on topic. I was also looking into the Plasma Direct technology from Okada Projects. They say that it will work with the pulse plugs, but they do not have any applications for the Fit.

 

Ouch! I was hoping that yours was a quick, simple problem. Guess not. I have decided not to return my plugs after all. I have no objection to them, and the cost wasn't that big of a deal. I don't feel cheated, but $100.00 certainly will buy other mods or pay a large part of their cost, that actually show immediate results.

I hope that your pedestrian status goes away soon enough to keep you from going crazy.

 

Okay boys and girls, the results are in and the conclusions are...

For me the results were DEVASTATING! I took the Fit to a local shop and had the car dyno'd three times. The first run was to get a baseline for comparison. The plugs were then changed out and a second run was completed. THERE WAS A 50HP DECREASE!!! It seems that one or more of the engine's cylinders were misfiring most likely due to a defective plug(s). The engine went into "limp mode" throwing an error code. Needless to say the plugs were taken out immediately and the originals put back in. The third run was to make sure that the engine had recovered. So after $146 dollars worth of runs and work I have decided to get my money back.



As for everyone else, the results are INCONCLUSIVE. I never got an actual result since one or more of the plugs were defective. Perhaps manxman can get a dyno run in since his plugs seem to be working properly.
But I am going to chalk this up to a waste of time and money.

 

I pm'd osborne to say that in his place, after all of the preparation and expense for the dyno runs, I would be EXTREMELY pissed off about the defective plug(s). My plugs do work fine, but since I didn't dyno the stock plugs, I have nothing to compare the new plugs to. I am not about to change plugs twice more just to dyno before and after with the new plugs. I don't even know where the nearest floor dyno is.

I should mention that my Fit feels a little quicker and stronger off the line since the plug change, but have not driven enough yet to get a good comparison of gas mileage with previous records. The perceived extra power is probably just my imagination, but I will give it a little more trust if the gas mileage is measurably better.

The installation instructions suggest that these plugs need to be handled carefully, and also tell you to follow the idle re-learn (disconnect battery before running engine with the new plugs).

Using capacitive discharge to intensify the spark and multiply the pulses is a great idea and works fine with systems like MSD, but in such SYSTEMS, the electronics are mounted away from the high temperatures of the cylinder head. These plugs are obviously IN the head, and the high temps. obviously limit the effectiveness and life span of the plugs.

osborne's experience shows you one of the risks inherent in merely TRYING these plugs. It will be interesting to hear from him if the plug marketer gives him any trouble in getting his refund.

 

Note that it is not the increased temperature that shortens the life of the plugs but the increased amount of electricity running though them. Every time a spark jumps the gap it takes part of the electrode with it, so even a CD ignition box will shorten the life of a spark plug. See below:

Center electrode

The center electrode is connected to the terminal through an internal wire and commonly a ceramic series resistance to reduce emission of radio noise from the sparking. The center electrode is usually the one designed to eject the electrons because it is the hottest (normally) part of the plug; it is easier to emit electrons from a hot surface, because of the same physical laws that increase emissions of vapor from hot surfaces. In addition, electrons are emitted where the electrical field strength is greatest; this is from wherever the radius of curvature of the surface is smallest, i.e. from a sharp point or edge rather than a flat surface. It would be easiest to pull electrons from a pointed electrode but a pointed electrode would erode after only a few seconds. Instead, the electrons emit from the sharp edges of the end of the electrode; as these edges erode, the spark becomes weaker and less reliable.

 

My point is that the capacitors that supposedly give the higher performance values in these plugs are most likely harmed by the high temps. of the cylinder head. Systems like MSD move the electronics (capacitors) AWAY from the engine. Of course all plugs wear out as the electrode disappears, and of course with higher energy and duration of the spark, the electrode will disappear faster. Of course the plug gap continues to increase as the electrode wears, and the spark gets weaker as the gap increases.

I gave our members credit for knowing how spark plugs work, and was trying to explain some of the other reasons for not buying THESE plugs.

 

Hello gents/ladies. First post, and I thought I'd add into this conversation on independent testing I've been doing with the Pulstar units.

A little about me: I'm the General Manager and tuner for a shop called Performance and Luxury Motorsports out of Franklin Park, IL. We had been asked to do some initial NA testing on two applications. One was an '03 Toyota Matrix, and my '07 Honda Fit. I'll repost some of the info I had placed on one of the Subaru technical forums I contribute to, but hope that this will at least help add another objective observation of the product.

For me at least, the fact that it did or did not make more power is a distant second to the fuel economy and emission testing that is the true mandate of the plug. That type of information will follow as the fuel logging continues over the next several weeks.

Glad to finally make it over here, and with no more delay, here's the post I put up on NASIOC.

---------------------------

OK, so here are some updates.

Car 1:

2007 Honda Fit (5MT), 24890 miles.

Originating plug gap on the NGK heatrange 6 iridiums that came out were confirmed at .045.

Pulstars went in at .045.



Subjective opinion is positive. All I can say is that the car feels "lighter". Throttle response is very positive, and the lower the rev-range, the better power delivery over stock. Especially obvious on low speed or second gear starts, rolling stops, etc.

Second car 2003 Toyota Matrix (4EAT), 94121 miles.

Originating plug gap on the factory heat range 5 NGK's was anywhere from .038-.041. Pulstars installed and gapped at factory .042.



Subjective observation is a similar "light" feeling to the pedal, but it also should be noted that the larger variance in performance vs car 1 could be due to the degraded plug condition.


Overall the tests were impressive. Objective time testing on the dyno saw between .1 and .3 seconds increase in pull times. But the big answer will be in fuel economy, as the fact that it made more power is a distant second to the original mandate of the plugs ability to improve fuel economy while reducing emissions.
